TABLE 2--Leaf
macronutrient content (mg plant-1) of mangabeira seedlings (Hancornia speciosa Gomes) grown in a complete nutrient solution or in macronutrient-deficient solutions.
The more you know about the
macronutrient breakdown of your food, the more likely you are to watch what you eat and make healthy choices.
"There is already agreement that reducing saturated fat lowers risk of heart disease, but the question of which
macronutrient to emphasize has been controversial," states Lawrence Appel, M.D., M.P.H., professor of medicine at the Johns Hopkins School of Medicine and lead author of the OmniHeart study, in a press release prior to the study's publication.
The draft guidelines advise long-term vitamin and mineral supplementation as needed, depending on the procedure, and periodic monitoring for micronutrient deficiencies in the first 2-3 weeks after surgery and for
macronutrient deficiencies in the first several months.
Sixty healthy postmenopausal women were randomly assigned in a crossover design to consume a low-fat diet or a diet of similar
macronutrient content in which one-half cup per day of unsalted soy nuts (providing 25 g of soy protein and 101 mg of isoflavones daily) replaced 25 g of non-soy protein.
There may be some differences in water loss on a low-carb diet and there may be a difference in compliance, but the bottom line is that a calorie is a calorie regardless of the
macronutrient consumed.
GMA based its recommendation on the National Academy of Sciences'
Macronutrient Report as well as FDA precedent for other nutrient content claims including "low fat," "reduced sodium", and "good source of calcium".
Although protein provides amino acids for promoting muscle growth and recovery from strength training, the most important
macronutrient for strength building is carbohydrate.
Children's patterns of
macronutrient intake and associations with restaurant and home eating.

Hall's research involved monitoring 17 healthy adult dogs and 27 cats over 28 days and used four types of food that were designed to taste equally good; with flavor out of the equation, the animals could make
macronutrient choices based only on what their bodies were telling them they needed.
The researchers found that the mean 12-month
macronutrient distributions were 48 versus 30 percent for carbohydrates, 29 versus 45 percent for fat, and 21 versus 23 percent for protein in the HLF versus HLC diets.
