We are told by our doctors to take vitamins. The advice is understandable. We do not get enough vitamins from our fruit and vegetables. Either we don’t eat enough, or they are so pump with water that the effectiveness of the vitamins is in doubt.

Which vitamins to take is another question. And the more you’ll ask the more answers you’ll get. Here is some order in the confusion and the recommended daily allowance by the food and drug administration.

We are told that in order to stay healthy we need to check the nutritional facts on the back of boxes of food we buy. But do we understand what they really mean? Here’s a short description.

Calories

– The amount of calories in a certain food is a way to measure how much heat will be released while burning that food. A man needs about 2,000 calories a day, a woman a little less depending on their activity levels. Calorie amount is given so we will know how rich or dense the food is so we can calculate how many calories we eat.
