Digestive System: Nutrient Absorption

Have you ever wondered where all of those digested food molecules are absorbed in your body? Well, before those carbohydrates, proteins, and fats can be absorbed, they must be broken down into smaller molecules. Carbohydrate digestion begins in the mouth, protein digestion begins in the stomach, and fat digestion begins in the intestines.

Once these materials have been broken down, nutrient absorption can occur. As food is processed along the digestive tract, most of the nutrients are absorbed through the walls of the small intestines. The nutrients are carried into the bloodstream where they can travel to all parts of the body. Other substances that are absorbed during digestion include vitamins, water, and salt.

Also interesting is Vitamin absorption as a part of nutrient absorption. ALL ONE founder Doug Ingoldsby shows on talk shows sometimes how even after 1/2 hour, many tablet type vitamins are undissolved in a glass of water and so are not well absorbed into the body either. His blog post on vitamin absorption is very revealing on this and shows the best ways to get supplements to be easily absorbed into the body. Thanks!
