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.
After you gain a basic understanding, you will want to remember that we are not all alike. "Whole foods'" can mean lots of whole wheat bread, whole grains, and nuts for one person, while another may have a sensitivity to wheat and an allergy to tree nuts. A person who loves meat might get adequate protein but not enough vitamins and minerals, while a vegetarian could be lacking in protein.
If a person is allergic to foods or cannot digest them properly, that individual might get little food value out of their diet. Foods that contain 'empty calories', like potato chips or sodas - or that are full of preservatives, sodium, or sugars - will destroy health rather than build it. Artificial flavors and colors are additives that may cause problems.
It is important to know what is in the food you plan to eat, in order to avoid empty calories or allergens. You should also know where it comes from. Produce that is imported might have been grown in an area with lax control over pesticide and herbicide use. If it comes from a country with strict controls, it could be premium fare. Remember that produce from far away was probably ripened during shipment, sprayed with fungicide, and could have lost much of its nutritional value.
You will find experts - many of them medical doctors - who advocate lots of good fat, almost no fat at all, complex carbohydrates as the basic food group, low-carb and high-protein diets, fruit only, vegetables only, or who say that you can eat anything you want if you exercise enough. The trick is to find out what works for you, create a program that builds health and fosters ideal weight, and stick to it.
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.
