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 just beginning a study of good food choices, the federal guidelines are not a bad place to start. You will get an overview of conventional wisdom about minimum daily requirements of vitamins and minerals, calories, protein, fats, and fiber. The human body is very efficient if given the nutrients it needs; a good diet is the foundation of health.
One complication is that not everyone is the same. Food that sustains one person might give another an allergy attack or gastric distress. Regularity might be usual for one person, who needs little fiber, while another might struggle for proper elimination no matter how much whole food is consumed.
Food can contain allergens that make it indigestible for a person who will get little or no nutrition out of it. Foods can also be laced with preservatives, artificial flavors and colors (that can trigger hyperactivity in children), sweeteners, sodium, or spices that might make it a poor choice. Fresh produce can be tainted with pesticide residue and could even be genetically modified.
This is why it pays to know what ingredients are in your food and where it comes from. Produce grown in other countries might have a higher pesticide content - but not necessarily. Exotic fruits and vegetables probably will be picked before full ripeness, and long shipping times can lessen the food value considerably.
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.
The best practice is to read as much reputable nutrition data as you can, to get a consensus of opinion. Then try some of the programs for yourself. If you are sensitive to wheat or dairy, you will soon know. If you must eliminate certain foods to feel your best, make sure to find acceptable sources of the nutrients you will be missing. The more you investigate and experiment, the more you will feel sure of satisfying your own personal needs.
