All too often we hear nutrition myths. They confuse many people and result in personal choices that compromise health and increase the risk of disease. In this powerpoint, Dr Esser reviews some foundational and a few specific myths and presents compelling science to set the record straight. Enjoy and remember to keep on asking questions and learning how you can achieve your best health in 2018.
5. âA global response to a
global problem: the epidemic
of overnutrition.â WHO
It is estimated that by 2020 2/3rds
of the global
burden of disease will be attributable to chronic
non-communicable diseases, most of them
strongly associated with diet. The nutrition
transition towards refined foods, foods of animal
origin, and increased fats plays a major role in
the current global epidemics of obesity, diabetes
and cardiovascular diseases, among other non-
communicable conditions. Sedentary lifestyles and the
use of tobacco are also significant risk factors. âŚâŚ.. A
concerted multi-sectoral approach, involving the use of
policy, education and trade mechanisms, is necessary
to address these matters.
6. Healthy living is the best revenge: findings from
the European Prospective Investigation Into
Cancer and Nutrition-Potsdam study 2009
⢠23,153 participants (35 to 65yr) for about 8 years
⢠Rates of type 2 diabetes mellitus, myocardial
infarction, stroke, and cancer
⢠4 Variables:
â Never smoking
â BMI<30
â 3.5 h/wk or more of physical activity
â healthy dietary principles (high intake of fruits,
vegetables, and whole-grain bread and low meat
consumption).
If you had all 4 factors at baseline you had
⢠78% lower risk of developing a chronic disease
â˘
⢠93% lower risk of diabetes
â˘81% lower risk of myocardial infarction
â˘50% lower risk of stroke, and
â˘36% lower risk of cancer

19. Vegetarian diets: what do we know of their
effects on common chronic diseases?
Am J Clin Nutr May 2009 vol. 89 no. 5 1607S-1612S
There is convincing evidence that vegetarians
have lower rates of coronary heart disease,
largely explained by low LDL cholesterol,
probable lower rates of hypertension and
diabetes mellitus, and lower prevalence of
obesity. Overall, their cancer rates appear to
be moderately lower than others living in the
same communities, and life expectancy
appears to be greater.
22. No Conflict
⢠More FiberâŚâŚâŚ
⢠More Micronutrients
⢠Less Saturated, Trans Fat, Cholesterol
⢠Fewer Refined foods
⢠Less Cholesterol
28. Salt
⢠1 tsp Table Salt = 2300mg Sodium
⢠1tsp Sea Salt = 2300 mg Sodium
⢠1tsp Himalayan Salt = 1680mg Sodium
⢠1tsp Kosher Salt = 1120 mg Sodium
â Varies by size of crystal, preparation etc
⢠Recommended < 2300mg ( < 1500mg per day)
29. Salt
⢠Takeaway:
â Salt is NOT a health food regardless of color, country
of origin, molecular size, micronutrient content etc
â Increases water retention, stimulates appetite
â Damages blood vessel walls, increases risk of heart
disease

⢠Artificial Sweeteners: A systematic review of
metabolic effects in youth Pediatric Obesity 2010
⢠However, recent animal studies provide intriguing information that supports an active metabolic role of artificial sweeteners. This systematic review
examines the current literature on artificial sweetener consumption in children and its health effects. Eighteen studies were identified. Data from
large, epidemiologic studies support the existence of an association between artificially-sweetened beverage consumption and weight gain in
children. Randomized controlled trials in children are very limited, and do not clearly demonstrate either beneficial or adverse metabolic effects of
artificial sweeteners. Presently, there is no strong clinical evidence for causality regarding artificial sweetener use and metabolic health effects, but it
is important to examine possible contributions of these common food additives to the global rise in pediatric obesity and diabetes.
⢠Relationship between artificial sweeteners and obesity
⢠Artificial Sweeteners may alter satiety and increase appetite and
food consumption

57. The Science
⢠Low-Carbohydrate Diets and All-Cause
Mortality: A Systematic Review and Meta-
Analysis of Observational Studies PLOS 2013
â Low-carbohydrate diets were associated with a
significantly higher risk of all-cause mortality
58. The Science
⢠Dietary Protein Intake and Incidence of Type
2 Diabetes in Europe: The EPIC-InterAct Case-
Cohort Study Diabetes Care 2014
â High total and animal protein intake was
associated with a modest elevated risk of type 2
diabetes in a large cohort of European adults. In
view of the rapidly increasing prevalence of type 2
diabetes, limiting iso-energetic diets high in
dietary proteins, particularly from animal sources,
should be considered.
59. The Science
⢠Low-Carbohydrate Diets and All-Cause and
Cause-Specific Mortality: Two Cohort Studies
Annals of Internal Medicine 2010
â A low-carbohydrate diet based on animal sources
was associated with higher all-cause mortality in
both men and women, whereas a vegetable-
based low-carbohydrate diet was associated with
lower all-cause and cardiovascular disease
mortality rates.
60. Meat
⢠Dietary Protein Intake and Risk of Type 2
Diabetes in US Men and Women Am. J. Epidemiol,
March 2016
⢠Investigated the associations between total, animal, and vegetable protein and
incident T2D in 72,992 women from the Nurses' Health Study (1984â2008), 92,088
women from Nurses' Health Study II (1991â2009) and 40,722 men from the Health
Professionals Follow-up Study (1986â2008).
⢠âSubstituting 5% of energy intake from vegetable protein for animal
protein was associated with a 23% (95% CI: 16, 30) reduced risk of
T2D. In conclusion, higher intake of animal protein was associated with an
increased risk of T2D, while higher intake of vegetable protein was associated with
a modestly reduced risk.â

Women: 46 g protein per day Men: 56 g of protein
EAR for adults is 0.66 grams of protein for every 2 pounds of weight. The RDA for adult men and women is 0.8 grams of protein for every 2 pounds of body weight.
If your goal is a âhealthy weightâ you either have to eat less of calorie dense foods or you can eat unlimited amounts of low calories, night nutirent dense foods. The law of thermodynamics will not be denied.
