Appropriately planned vegetarian diets are healthful and nutritionally adequate for all stages of the human life cycle, including during pregnancy, lactation, infancy, childhood, and adolescence. [1]
Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.
Iron helps to strengthen the body's resistance to infections and diseases by facilitating the growth and health of immune cells. So, it is vital for the proper functioning of the immune system.
All macronutrients except water are required by the body for energy, however, this is not their sole physiological function. The energy provided by macronutrients in food is measured in kilocalories, usually called Calories, where 1 Calorie is the amount of energy required to raise 1 kilogram of water by 1 degree Celsius.

This, in turn, leads to the production of magical compounds called short-chain fatty acids that help reduce inflammation throughout the body. Resistant starch has another neat trick: Research ...
The seven major classes of nutrients are carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. [7] Nutrients can be grouped as either macronutrients or micronutrients (needed in small quantities). Carbohydrates, fats, and proteins are macronutrients, and provide energy. [7] Water and fiber are macronutrients, but do not provide ...
