Adults generally need fewer calories as they age, with recommended daily calorie intake ranges being 1600-2400 calories for those aged 23-50, 1400-2200 calories for ages 51-75, and 1200-2000 calories for ages 75 and above. Nutrient needs also change with age due to factors like declining organ function and changes in metabolism. Common health conditions that affect adults include heart disease, cancer, diabetes, osteoporosis, and prostate cancer, with risk influenced by diet and lifestyle habits. Meeting nutrition needs becomes more challenging for older adults due to physical and social factors.
