Food Labels

Do you know what "light" and "low-fat" really mean? Here's how to read between the lines on food labels.


Vitamins are essential components of our diets. They are required to maintain normal growth, development, and function of our bodies. Vitamins are classified as either fat-soluble (vitamins A, D, E, K) or water-soluble (all others) based on the way the body absorbs these nutrients. Many of us take a daily vitamin supplement to be "healthy," even though all our needs can be met with a balanced diet. Vitamin deficiencies can result for a number of reasons, including inadequate dietary intake, inability to absorb consumed nutrients, increase need or loss of vitamins, or by interactions with certain medications. Both vitamin deficiencies and excesses can have serious health consequences. There are certain vitamins in which more may be better, but care must be taken to avoid toxicity.


Malnutrition is a broad topic but simply indicates inadequate nourishment to maintain health and normal development.
