Nutrition data is readily available; for instance, you can access federal guidelines issued for public information and read the labels on food packages. Online sites and books of advice abound. There is more information than anyone can absorb. Both conventional and alternative views vie for attention and the money that consumers spend on food and supplements.
If you are a beginner to this study, read the federal guidelines for a basic, conventional view of foods that promote health. There will be minimum daily requirements for vitamins and minerals; an ideal calorie allotment geared to age, height, and activity level; a standard for protein, carbohydrate, and fiber intake.
Things are complicated by the fact that everyone is an individual, with specific needs that might be different from those of the general public or even members of the same family. For instance, whole wheat bread could be a good source of fiber, B vitamins, and calcium for those who can digest wheat gluten without problems. For others, even one slice can cause gastric distress.
If a person has a sensitivity or an allergy to certain foods, they will probably be unable to absorb nutrients from that food. In fact, a severe case can mean that a person can eat a lot but actually suffer from malnutrition. Some processed food has too much sodium, an overload of preservatives, artificial flavors and colors, and are loaded with fat or sugar.
It is important to know what is in your food, where it comes from, and how fresh it is. Vitamins may break down over long periods of shipping or of sitting on a shelf, and minerals can be lost during preparation - such as in canned vegetables or soups. Fresh local produce may be a better choice, but it is still important to know how it was grown and prepared for market.
Advice books on weight control, energy, mental alertness, and more abound, each with a point of view. One says to eat whole wheat bread you make yourself, and others that say you should never eat the grain in any form. Some books promote high protein, others say that a small number of almonds contain all the protein you need for one day.
Make sure that your sources are reputable and not cleverly disguised advertisements for certain foods or programs. Find facts that many experts agree on or which are supported by clinical research, factor in your own needs and sensitivities, and choose what advice you will follow. Nutrition data is great if you use it as a guide rather than getting discouraged by the scope and variety.
