What is Raw food ?
The dictionary definition says it all : Raw /
uncooked; being natural condition; not processed
or refined. Since uncooked, unprocessed and
unrefined foods are alive until the moment we
eat them, they give us that same energy, that vital
life-force that increases our health and make us
strong and vibrant.

Raw food contain enzymes and vitamins that are
destroyed when exposed to high temperatures.
That is why the raw food “rule” is not to heat
food above 40-47C / 104-117F if you want to
protect all thermally unstable (heat sensitive)
nutrients

Raw foodism (or following a raw food diet) is the
dietary practice of eating only uncooked,
unprocessed foods.
Depending on the exact philosophy or type of
lifestyle and results desired, raw food diets may
include a selection of fruits, vegetables, nuts, seeds,
eggs, fish, meat and dairy products.It may also
include simply processed foods such as various
types of sprouted seeds, cheese, and fermented
foods such as yogurts, kefir, kombucha or
sauerkraut, but generally not foods that have been
pasteurized, homogenized, or produced with the
use of synthetic pesticides, chemical fertilizers,
industrial solvents or chemical food additives.

Raw food diets are not anything new. Popular health
concepts often re-cycle in history and re-appear in a
different era as a "new" idea. Sylvester Graham
promoted raw food diets in 1839. He condemned
cooking and claimed that illness could be prevented by
eating only raw foods. Ellen White, however,
recommended the use of both raw and cooked foods.
She emphasized that some foods needed to be
thoroughly cooked. Her writings make it abundantly
clear that in her household they baked or boiled the
potatoes and beans, cooked their grains and baked
their bread thoroughly.

In all variants of the raw food diet, food is
consumed predominantly or exclusively as
uncooked and unprocessed raw food; the main
components of the diet are fruits, nuts, seeds, and
sprouted grains and beans.

By simply incorporating more raw food in your
diet you are providing your body with an
abundance of essential enzymes, nutrients in
fibre, all of which are needed for the body to
process food, detoxify, create energy and
perform at its optimum.

The Raw Food Diet, according to the food variety,
can be divided into:
1. Raw veganism,
2. Raw vegetarianism
3. Raw animal food diet.
Raw veganism considered to be mostly
widespread.

Raw veganism is a plant-based diet that involves no
cooking. No food is heated above 104 degrees
Fahrenheit (40 degrees Celsius). Foods are eaten
fresh, dehydrated with low heat or fermented.

Enjoying delicious raw foods that optimize your
health by alkalizing your body.At that rate your
elimination system can get rid of the toxins created
when you cook. But when you eat more cooked
food you are consuming acidic toxins faster than
your body can eliminate them so they back up,
disrupting your body's delicate acid/alkaline balance,
a major cause of excess weight and disease.
Heating food above 118 degrees F. causes the
chemical changes that create acidic toxins, including
the carcinogens, mutagens and free-radicals
associated with diseases like diabetes, arthritis, heart
disease and cancer. Cooking also destroys the live
enzymes that aid in digestion and health.

Page 11
Your body is actually sort of an alkaline battery, running on
electrons.All life-giving chemical reactions only happen when
electrons or energy flows between atoms. Cooking or
processing causes food to lose electrons - the source of the
energy your body needs.Things that are healthy 'contribute"
electrons/energy, and are called alkalizing or "reducing."Things
that are unhealthy steal electrons/energy, and are called acidic or
“oxidizing” (which means to burn up, rust, break down or
decay).
Your body is designed to be alkaline, like the battery! Because
the pH scale is logarithmic even a fraction of a point can create
huge changes to health! One hydroxyl molecule (-OH) in 550
million is enough to make water conductive. In fact, most
important processes in your body only work within a very
narrow pH range. For example, if the pH of your blood falls to
the low end of its normal range (~7.35-7.45), a .10 difference, it
could reduce the oxygen levels in your blood by as much as
300%!

Fruit and vegetables, especially raw leafy greens,
which are full of chlorophyll, have the added benefit
of being incredibly alkalizing.
Eating cooked, processed foods and animal products,
this increases the body acidity.Too many acid can
promote inflammation, lower immune function and
reduce levels of alkaline minerals, such as calcium
and magnesium.

Processed vegetables comprised mainly
cooked vegetables. Cooked vegetables also
have a generally lower dietary fiber content
than raw ones, vitamin C can be lost in

Our immune system also becomes stronger and we
have more energy and stamina. Many people
experience intense mental clarity and better focus
after introducing more natural foods into their diet.
Clear complexion, strong hair and nails can also be
side effects of eating this way.

Dietary guidelines recommend a high intake of
vegetables and fruits and a low intake of SFAs and
cholesterol to reduce cardiovascular morbidity. In
this context, a large body of evidence indicates
that predominantly plant-based diets (vegetarian)
can effectively contribute to the prevention of
cardiovascular disease (CVD).

The nutrient-rich raw food is high in antioxidants,
phytochemicals, vitamins, minerals, fiber, and healthy
fats (such as omega-3 fatty acids),
so it maximizes health and vitality.
Raw food rich in antioxidants, phytonutrients, and vitamins
that protect the body from free radicals, which attack
healthy cells--and people who are well nourished tend to
feel good and maintain a healthy body weight well into
their golden years.
Fats, especially heat-processed oils, slow you down because
they require long periods of digestion, which steals energy
from your body. Light foods, such as fruits and vegetables,
digest easily.

less sleep is required when you eat foods that are fresh
and light.When you consume heavy, cooked foods,
especially in the evening, several hours of sleep time are
spent digesting food rather than moving you to the
deep sleep zone that is required to reach beta levels
and the dream state.
Whole, ripe, raw organic plant foods provide the power
needed for strong mental acuity.The essential fats that
the brain requires, such as omega-3 fatty acids, are in
leafy greens, flaxseed, chia, hemp, and walnuts as well as
many other raw plant foods.The human brain also
should get plenty of water, magnesium, and organic
sodium; whole raw foods offer an abundance of these
nutrients.

When our liver overworked and we cant’s detoxify
effectively, waste products and toxins will be stored
in our fat cells – so there more toxins that are in

effectively, such as balancing blood sugar, reducing
cravings, eliminating excess hormones and
producing bile to break down fats and keep
cholesterol levels healthy.

Low mineral absorption.
Many nutrients are locked within the tough fibrous
matrix of vegetables. These are bio unavailable if eaten
raw because:
a) Human beings cannot digest cellulose and other
fibrous starches. Humans lack the enzymes to digest
cellulose and other vegetable fibers. This is a fact, even
if one does not like it. Taking a cellulose enzyme might
help a little, but will not overcome this problem.
b) Many people also have very weak digestion, making it
even harder to digest vegetable fibers. Cooking breaks
down the starch and cellulose and other fibers,
releasing the minerals, in particular, and perhaps other
phytonutrients. While raw food provides more of a few
vitamins such as vitamins C and E, this is more than
offset, in most cases, because we cannot digest
vegetable fibers very well.

Raw foods are somewhat irritating to the
digestive tract.
Sugars found in fruit and other sweets are also

Raw food fills up the stomach, reducing the amount
of other food that one can eat.
This may sound like a silly reason to avoid raw foods.
However, the bodies today are so nutrient-deficient
that filling your stomach with large salads, for
example, is not healthful at all. One does not obtain
enough minerals from salads, and there is little room
left for other more nutrient-dense foods.

Food Poisoning
Eating raw foods, such as meat or fish, contaminated
with bacteria, parasites, viruses or harmful chemicals
can cause food-borne illnesses. Diarrhea is a common
symptom of eating contaminated foods that can
interfere with absorption of nutrients from foods.
Research conducted by scientists at the Federal
University of Bahia in Brazil and published in the
"Journal of Pediatrics" in August 2001 discovered that
diarrhea can cause incomplete absorption of
carbohydrates, such as fruit juice.

Cleanliness
This is a problem today with some raw foods,
including even salads at salad bars. It is mainly a
problem in restaurants, where one does not know
how clean the vegetables are.
It is also a serious problem with all meats, fish, eggs
and seafood. Please do not eat these raw, no matter
what anyone claims! They contain bacteria, parasites
and other microorganisms, many of which are killed
by proper cooking.

Ulcers
Eating raw foods can increase your risk of bacterial
infections that can affect your gastrointestinal tract and
your ability to digest and absorb nutrients. Helicobacter
pylori, or H. pylori, is a bacterium that can cause
stomach and small intestinal ulcers. Research by
scientists at that Department of Health and Animal
Welfare in Valenzano, Italy and published in the
"International Journal of Food Microbiology" in May
2008 discovered that raw goat milk may contain H.
pylori DNA. The scientists conclude that raw goat milk
may increase the risk of H. pylori infections in humans
who consume it.

Maldigestion
Eating plentiful amounts of vegetables each day can
help you reduce your risk of chronic diseases, such as
cancer, heart disease, Type 2 diabetes and high blood
pressure, according to the Centers for Disease
Control and Prevention. However, eating raw
vegetables may cause gas and bloating. Raw vegetables
contain enzymes that may help you digest the food,
but they also contain an insoluble fiber called cellulose
that humans are unable to digest. Unlike cows, human
intestines do not have bacteria that produce an
enzyme called cellulase to help you digest cellulose
into sugars. However, fermenting raw vegetables can
pre-digest the fiber before you eat them.

Physical pH of raw foods.
You’ve probably heard of foods being “alkaline” or “acidic”—
that is, some leave an alkaline residue after digestion, while
others leave an acidic one. But when it comes to dental health,
you’ve also got to consider the actual pH of food when it first
enters your mouth and hits the surface of your teeth.
Regardless of what happens to food after metabolization, the
initial contact is what can cause the most damage.
Here’s a list of the pH of some raw foods taken from FDA
measurements. The lower the number, the more acidic the
food; 7 is considered neutral, although anything with a pH of 5
or greater is less likely to damage your teeth. Citrus often gets
a bad rap, but notice that some other fruits—especially
berries, plums, and grapes—have an even lower pH than
oranges. And bear in mind that unripe fruit will typically have
values lower than the ones listed.

Potential effects of cooking
Thyroid Health
Many vegetables in the cruciferous family such as kale,
broccoli, cauliflower, cabbage, mustard greens and
brussel sprouts contain what are known as goitrogens.
Goitrogens are naturally occurring compounds in some
foods that may block thyroid function and can
eventually lead to goiter and hypothyroidism. For
people with an already weakened thyroid function, or
for those who have a propensity to thyroid disorders,
goitrogens can worsen the ability of your thyroid to
produce important hormones. Goitrogens can be
deactivated by heat. So, cooking your vegetables can
deactivate a good amount of goitrogens.

Potential effects of cooking
Digestive Health
Plants and vegetables have cellulose and other fibrous
structures that our stomachs have a hard time breaking
down. Human stomachs are not like other vegetarian
animals such as cows. Many of these animals have extra
stomachs to help break down and digest the tough plants
and grasses they eat. Humans, unfortunately, don’t have these
extra stomachs to break down all the fibrous cellulose
contained in plants.This makes it especially difficult to digest
vegetable fibers.When we’re constantly eating foods that
our bodies cannot digest, our ability to digest foods in
general is weakened.A weakened digestive system can cause
bloating, indigestion, constipation or loose stools, weight
gain, malnutrition, food allergies and a lowered immune
system. Our digestive system is a key element to good
health, so it’s important to ensure it is healthy and
functioning properly.

Nutrient Absorption
If we are unable to digest our foods, there's a good
chance that we're not absorbing many of the nutrients
in the foods we eat. A lot of the nutrients in vegetables
are stored in its tough fibers. Unless we break down
these vegetable fibers, our bodies will not be able to
use these nutrients.

Cooking, especially for long periods, can damage
some vitamins. Boiling and steaming causes some
vitamins and minerals to seep out of the food.
Chemicals thought to cause cancer are formed when
food is burned or oils are heated above the point at
which they smoke. Deep-frying foods causes trans
fats to form.
On the plus side, cooking can break down food
components that would otherwise bind minerals and
prevent their absorption. It can soften fiber, which
allows more food to be eaten. Cooking liberates
some nutrients, such as beta-carotene and other
antioxidants, for easier absorption

Raw food

  • 2. Page 2 What is Raw food ? The dictionary definition says it all : Raw / uncooked; being natural condition; not processed or refined. Since uncooked, unprocessed and unrefined foods are alive until the moment we eat them, they give us that same energy, that vital life-force that increases our health and make us strong and vibrant. Dunja Gulin. (2012) Raw Food Kitchen: naturally vibrant recipes for breakfast, snacks, main & desserts. UK: Ryland Peters & small
  • 3. Page 3 Raw food contain enzymes and vitamins that are destroyed when exposed to high temperatures. That is why the raw food “rule” is not to heat food above 40-47C / 104-117F if you want to protect all thermally unstable (heat sensitive) nutrients Dunja Gulin. (2012) Raw Food Kitchen: naturally vibrant recipes for breakfast, snacks, main & desserts. UK: Ryland Peters & small
  • 4. Page 4 Raw foodism (or following a raw food diet) is the dietary practice of eating only uncooked, unprocessed foods. Depending on the exact philosophy or type of lifestyle and results desired, raw food diets may include a selection of fruits, vegetables, nuts, seeds, eggs, fish, meat and dairy products.It may also include simply processed foods such as various types of sprouted seeds, cheese, and fermented foods such as yogurts, kefir, kombucha or sauerkraut, but generally not foods that have been pasteurized, homogenized, or produced with the use of synthetic pesticides, chemical fertilizers, industrial solvents or chemical food additives. http://en.wikipedia.org/wiki/Raw_foodism
  • 5. Page 5 Raw food diets are not anything new. Popular health concepts often re-cycle in history and re-appear in a different era as a "new" idea. Sylvester Graham promoted raw food diets in 1839. He condemned cooking and claimed that illness could be prevented by eating only raw foods. Ellen White, however, recommended the use of both raw and cooked foods. She emphasized that some foods needed to be thoroughly cooked. Her writings make it abundantly clear that in her household they baked or boiled the potatoes and beans, cooked their grains and baked their bread thoroughly. Winston Craig (2014). Raw Foods - Claims and Reality. Retrieve from http://www.vegetarian-nutrition.info/updates/going_raw.php
  • 6. Page 6 In all variants of the raw food diet, food is consumed predominantly or exclusively as uncooked and unprocessed raw food; the main components of the diet are fruits, nuts, seeds, and sprouted grains and beans. Messina V., Mangels A. R., Messina M. J.What is a raw foods diet and are there any risks or benefits associated with it?. The Dietitian’s Guide to Vegetarian Diets: Issues and Implications. Jones and Bartlett Publishers Boston, MA.
  • 7. Page 7 By simply incorporating more raw food in your diet you are providing your body with an abundance of essential enzymes, nutrients in fibre, all of which are needed for the body to process food, detoxify, create energy and perform at its optimum. Christine Bailey (2012), The Raw Food Diet. London: Duncan Baird Publisher
  • 8. Page 8 The Raw Food Diet, according to the food variety, can be divided into: 1. Raw veganism, 2. Raw vegetarianism 3. Raw animal food diet. Raw veganism considered to be mostly widespread. Healthy Lifestyle (2012). The Raw Food Diet – good or bad? Retrieve from http://www.healthylifestyleart.com/the-raw-food-diet-good-or-bad
  • 9. Page 9 Raw veganism is a plant-based diet that involves no cooking. No food is heated above 104 degrees Fahrenheit (40 degrees Celsius). Foods are eaten fresh, dehydrated with low heat or fermented. ChristopherWanjek (2013) Reality Check: 5 Risks of RawVegan Diet. Retrieve from http://www.livescience.com/26278-risks-raw-vegan-diet.html
  • 10. Page 10 Enjoying delicious raw foods that optimize your health by alkalizing your body.At that rate your elimination system can get rid of the toxins created when you cook. But when you eat more cooked food you are consuming acidic toxins faster than your body can eliminate them so they back up, disrupting your body's delicate acid/alkaline balance, a major cause of excess weight and disease. Heating food above 118 degrees F. causes the chemical changes that create acidic toxins, including the carcinogens, mutagens and free-radicals associated with diseases like diabetes, arthritis, heart disease and cancer. Cooking also destroys the live enzymes that aid in digestion and health. Robert Alan Ross (2009). Why Alkalizing Raw Food IsThe KeyTo Health. Retrieve from http://www.rawfoodlife.com/#ixzz3PMill7Ii
  • 11. Page 11 Your body is actually sort of an alkaline battery, running on electrons.All life-giving chemical reactions only happen when electrons or energy flows between atoms. Cooking or processing causes food to lose electrons - the source of the energy your body needs.Things that are healthy 'contribute" electrons/energy, and are called alkalizing or "reducing."Things that are unhealthy steal electrons/energy, and are called acidic or “oxidizing” (which means to burn up, rust, break down or decay). Your body is designed to be alkaline, like the battery! Because the pH scale is logarithmic even a fraction of a point can create huge changes to health! One hydroxyl molecule (-OH) in 550 million is enough to make water conductive. In fact, most important processes in your body only work within a very narrow pH range. For example, if the pH of your blood falls to the low end of its normal range (~7.35-7.45), a .10 difference, it could reduce the oxygen levels in your blood by as much as 300%! Robert Alan Ross (2009). Why Alkalizing Raw Food IsThe KeyTo Health. Retrieve from http://www.rawfoodlife.com/#ixzz3PMill7Ii
  • 12. Page 12 Fruit and vegetables, especially raw leafy greens, which are full of chlorophyll, have the added benefit of being incredibly alkalizing. Eating cooked, processed foods and animal products, this increases the body acidity.Too many acid can promote inflammation, lower immune function and reduce levels of alkaline minerals, such as calcium and magnesium. Christine Bailey (2012), The Raw Food Diet. London: Duncan Baird Publisher
  • 13. Page 13 Processed vegetables comprised mainly cooked vegetables. Cooked vegetables also have a generally lower dietary fiber content than raw ones, vitamin C can be lost in cooking water Rickman JC, Barrett DM, Bruhn CM (2007) Nutritional comparison of fresh, frozen and canned fruits and vegetables. Part 1.Vitamins C and B and phenolic compounds. Journal of the Science of Food and Agriculture 87: 930–944.
  • 14. Page 14 Our immune system also becomes stronger and we have more energy and stamina. Many people experience intense mental clarity and better focus after introducing more natural foods into their diet. Clear complexion, strong hair and nails can also be side effects of eating this way. Dunja Gulin. (2012) Raw Food Kitchen: naturally vibrant recipes for breakfast, snacks, main & desserts. UK: Ryland Peters & small Health benefits :
  • 15. Page 15 Dietary guidelines recommend a high intake of vegetables and fruits and a low intake of SFAs and cholesterol to reduce cardiovascular morbidity. In this context, a large body of evidence indicates that predominantly plant-based diets (vegetarian) can effectively contribute to the prevention of cardiovascular disease (CVD). Hu F. B. Plant-based foods and prevention of cardiovascular disease: an overview.Am. J. Clin. Nutr. 2003;78:544S-551S. Health benefits :
  • 16. Page 16 The nutrient-rich raw food is high in antioxidants, phytochemicals, vitamins, minerals, fiber, and healthy fats (such as omega-3 fatty acids), so it maximizes health and vitality. Raw food rich in antioxidants, phytonutrients, and vitamins that protect the body from free radicals, which attack healthy cells--and people who are well nourished tend to feel good and maintain a healthy body weight well into their golden years. Fats, especially heat-processed oils, slow you down because they require long periods of digestion, which steals energy from your body. Light foods, such as fruits and vegetables, digest easily. Dan Ladermann & Cherie Sorie. (2013)Raw Food For Dummies. USAToday Magazine. Vol. 141 Issue 2816, p60-61.2p. Health benefits :
  • 17. Page 17 less sleep is required when you eat foods that are fresh and light.When you consume heavy, cooked foods, especially in the evening, several hours of sleep time are spent digesting food rather than moving you to the deep sleep zone that is required to reach beta levels and the dream state. Whole, ripe, raw organic plant foods provide the power needed for strong mental acuity.The essential fats that the brain requires, such as omega-3 fatty acids, are in leafy greens, flaxseed, chia, hemp, and walnuts as well as many other raw plant foods.The human brain also should get plenty of water, magnesium, and organic sodium; whole raw foods offer an abundance of these nutrients. Dan Ladermann & Cherie Sorie. (2013). Raw Food For Dummies. USAToday Magazine. Vol. 141 Issue 2816, p60-61.2p. . Health benefits :
  • 18. Page 18 When nutrient- and water-deficient foods--including pasta, pizza, and other fare that is laden with hydrogenated, saturated, and cooked fats and salt--are replaced with nutrient-dense whole plant foods and healthy fats, brain function improves. Reduces or even eliminates their respiratory problems, colds, flus, and allergies.A raw diet especially is effective for people who are intolerant of dairy, wheat, and soy because raw foods virtually have no hidden ingredients. Apples and carrots, for instance, are dairy- and lactose- free, wheat- and grain-free, soy-free, egg-free, and even corn free.A raw diet would eliminate a lot of allergy- related worries. Dan Ladermann & Cherie Sorie. (2013). Raw Food For Dummies. USAToday Magazine.Vol. 141 Issue 2816, p60-61. 2p. Health benefits :
  • 19. Page 19 When our liver overworked and we cant’s detoxify effectively, waste products and toxins will be stored in our fat cells – so there more toxins that are in our bodies. By nourishing the liver with raw foods, we also enable it to carry out other important tasks more effectively, such as balancing blood sugar, reducing cravings, eliminating excess hormones and producing bile to break down fats and keep cholesterol levels healthy. Christine Bailey (2012), The Raw Food Diet. London: Duncan Baird Publisher Health benefits :
  • 20. Page 20 The present study, found that raw fruit and vegetable consumption was inversely related with CHD (Coronary Heart Disease) incidence.To the best of our knowledge, this is the first prospective cohort study that examined raw fruit and vegetables using an integral approach raw fruit and vegetables are rich sources of nutrients and bioactive phytochemicals that may have beneficial effects on CHD incidence.

  • 21. Page 21 It is well-known that processing improves the bioavailability and bio accessibility of bioactive compounds in fruits and vegetables. Heat treatment enhances the bioavailability and strengthens the beneficial health effects of lycopene as well as carotenes and folate. Lycopene, for example, the main carotenoid in tomatoes, accounts for ,50% of the carotenoids in human blood and is suggested to protect against CVD (cardiovascular disease).

  • 22. Page 22 To release all the valuable nutrients from within the cells, the cell walls need to be ruptured. It is not easy. This is why eating greens without masticating the thoroughly would not satisfy on nutritional needs. In simple words, we need to chew our greens to a creamy consistency in order to get this benefits. Victoria Boutenko (2007). How to End your dependency on cooked Food . California: North Atlantic books
  • 23. Page 23 There are five main types of nutrients: carbohydrates, proteins, fats, vitamins and minerals. In addition to the big five, water and fiber are also essential for our body to function properly.The staple ingredients of a largely raw-food diet are rich in carbohydrates, water,‘good‘ fats, fibre, vitamins and minerals Dunja Gulin.

  • 25. Page 25 Vegetables in the markets and restaurants had higher total coliforms and E. coli counts than the vegetables at the vegetable cultivation fields. it was found that vegetables are washed in nearby canals after harvesting. Those canals are contaminated with human and animal excreta, which in turn may contaminate the vegetables.

A number of major food poisonings have been caused by raw or improperly cooked foods contaminated with Salmonella and E. coli 07:H157. Sufficient heat is required to destroy these dangerous organisms. Winston Craig (2014).Raw Foods - Claims and Reality. Retrieve from http://www.vegetarian-nutrition.info/updates/going_raw.php
  • 27. Page 27 Low mineral absorption. Many nutrients are locked within the tough fibrous matrix of vegetables. These are bio unavailable if eaten raw because: a) Human beings cannot digest cellulose and other fibrous starches. Humans lack the enzymes to digest cellulose and other vegetable fibers. This is a fact, even if one does not like it. Taking a cellulose enzyme might help a little, but will not overcome this problem. b) Many people also have very weak digestion, making it even harder to digest vegetable fibers. Cooking breaks down the starch and cellulose and other fibers, releasing the minerals, in particular, and perhaps other phytonutrients. While raw food provides more of a few vitamins such as vitamins C and E, this is more than offset, in most cases, because we cannot digest vegetable fibers very well. Lawrence Wilson (2014).

  • 28. Page 28 Raw foods are somewhat irritating to the digestive tract. Sugars found in fruit and other sweets are also irritating. One reason for this may be that they feed improper intestinal microorganisms such as yeasts and parasites. Lawrence Wilson (2014). Raw Food and Juicing.The Center For Development.

  • 29. Page 29 Raw food fills up the stomach, reducing the amount of other food that one can eat. This may sound like a silly reason to avoid raw foods. However, the bodies today are so nutrient-deficient that filling your stomach with large salads, for example, is not healthful at all. One does not obtain enough minerals from salads, and there is little room left for other more nutrient-dense foods. Lawrence Wilson (2014). Raw Food and Juicing. The Center For Development.

  • 30. Page 30 Food Poisoning Eating raw foods, such as meat or fish, contaminated with bacteria, parasites, viruses or harmful chemicals can cause food-borne illnesses. Diarrhea is a common symptom of eating contaminated foods that can interfere with absorption of nutrients from foods. Research conducted by scientists at the Federal University of Bahia in Brazil and published in the "Journal of Pediatrics" in August 2001 discovered that diarrhea can cause incomplete absorption of carbohydrates, such as fruit juice.

  • 31. Page 31 Cleanliness This is a problem today with some raw foods, including even salads at salad bars. It is mainly a problem in restaurants, where one does not know how clean the vegetables are. It is also a serious problem with all meats, fish, eggs and seafood. Please do not eat these raw, no matter what anyone claims! They contain bacteria, parasites and other microorganisms, many of which are killed by proper cooking. Jeffrey Traister ( 2012).

  • 32. Page 32 Ulcers Eating raw foods can increase your risk of bacterial infections that can affect your gastrointestinal tract and your ability to digest and absorb nutrients. Helicobacter pylori, or H. pylori, is a bacterium that can cause stomach and small intestinal ulcers. Research by scientists at that Department of Health and Animal Welfare in Valenzano, Italy and published in the "International Journal of Food Microbiology" in May 2008 discovered that raw goat milk may contain H. pylori DNA. The scientists conclude that raw goat milk may increase the risk of H. pylori infections in humans who consume it. Jeffrey Traister ( 2012). Digestion Problems From Raw Food.

  • 33. Page 33 Maldigestion Eating plentiful amounts of vegetables each day can help you reduce your risk of chronic diseases, such as cancer, heart disease, Type 2 diabetes and high blood pressure, according to the Centers for Disease Control and Prevention. However, eating raw vegetables may cause gas and bloating. Raw vegetables contain enzymes that may help you digest the food, but they also contain an insoluble fiber called cellulose that humans are unable to digest. Unlike cows, human intestines do not have bacteria that produce an enzyme called cellulase to help you digest cellulose into sugars. However, fermenting raw vegetables can pre-digest the fiber before you eat them. Jeffrey Traister ( 2012). Digestion Problems From Raw Food.

  • 36. Page 36 Physical pH of raw foods. You’ve probably heard of foods being “alkaline” or “acidic”— that is, some leave an alkaline residue after digestion, while others leave an acidic one. But when it comes to dental health, you’ve also got to consider the actual pH of food when it first enters your mouth and hits the surface of your teeth. Regardless of what happens to food after metabolization, the initial contact is what can cause the most damage. Here’s a list of the pH of some raw foods taken from FDA measurements. The lower the number, the more acidic the food; 7 is considered neutral, although anything with a pH of 5 or greater is less likely to damage your teeth. Citrus often gets a bad rap, but notice that some other fruits—especially berries, plums, and grapes—have an even lower pH than oranges. And bear in mind that unripe fruit will typically have values lower than the ones listed. Denise Minger (2010). Dental Drama:Tooth Problems on the Raw Diet (Part 1).

  • 38. Page 38 Potential effects of cooking Thyroid Health Many vegetables in the cruciferous family such as kale, broccoli, cauliflower, cabbage, mustard greens and brussel sprouts contain what are known as goitrogens. Goitrogens are naturally occurring compounds in some foods that may block thyroid function and can eventually lead to goiter and hypothyroidism. For people with an already weakened thyroid function, or for those who have a propensity to thyroid disorders, goitrogens can worsen the ability of your thyroid to produce important hormones. Goitrogens can be deactivated by heat. So, cooking your vegetables can deactivate a good amount of goitrogens. Caroline La (2014).3 Reasons No One Should Be On A Raw Foods Diet.

  • 39. Page 39 Potential effects of cooking Digestive Health Plants and vegetables have cellulose and other fibrous structures that our stomachs have a hard time breaking down. Human stomachs are not like other vegetarian animals such as cows. Many of these animals have extra stomachs to help break down and digest the tough plants and grasses they eat. Humans, unfortunately, don’t have these extra stomachs to break down all the fibrous cellulose contained in plants.This makes it especially difficult to digest vegetable fibers.When we’re constantly eating foods that our bodies cannot digest, our ability to digest foods in general is weakened.A weakened digestive system can cause bloating, indigestion, constipation or loose stools, weight gain, malnutrition, food allergies and a lowered immune system. Our digestive system is a key element to good health, so it’s important to ensure it is healthy and functioning properly. Caroline La (2014). 3 Reasons No One Should Be On A Raw Foods Diet.

  • 40. Page 40 Potential effects of cooking Nutrient Absorption If we are unable to digest our foods, there's a good chance that we're not absorbing many of the nutrients in the foods we eat. A lot of the nutrients in vegetables are stored in its tough fibers. Unless we break down these vegetable fibers, our bodies will not be able to use these nutrients.

  • 42. Page 42 Cooking, especially for long periods, can damage some vitamins. Boiling and steaming causes some vitamins and minerals to seep out of the food. Chemicals thought to cause cancer are formed when food is burned or oils are heated above the point at which they smoke. Deep-frying foods causes trans fats to form. On the plus side, cooking can break down food components that would otherwise bind minerals and prevent their absorption. It can soften fiber, which allows more food to be eaten. Cooking liberates some nutrients, such as beta-carotene and other antioxidants, for easier absorption Jack Norris, Ginny Messina, MPH, RD. (2010) Vegan For Life.
