Document Summary
Not used by average people: acceptable macronutrient distribution ranges (amdr): what percentage of calories should be given to each macronutrient, carbs- 45-65% of kcals, fats- 20-35% of kcals, proteins- 10-35% of kcals. Dri nuances: different recs for different segments of the population. Ex: different recommendations of iron for men and women: optimal recommendations, not minimums, different from daily values seen on food labels- which are good for comparing foods, not nutrient intake goals for individuals. The usda (us government) issues the dietary guidelines every 5 years: committee of nutrition experts, influenced by science politics. The guidelines: follow a healthy eating pattern across the lifespan: variety of vegetables from all subgroups- dark green, red and orange, legumes, starchy. Grains- at least half of which are whole. A variety of protein foods- seafood, lean meats and poultry, eggs, legumes, nuts, seeds, oil. Consume less than 10% of kcals from added sugars and saturated fats, and less than 2,300 mg sodium.
