Well, that's very kind of you to say, Gumby.

I learn a lot from this forum, not just about investing, and I like giving to it, too.
"Food" vs. "Ingredients": The standard processed food (I hesitate to use the word "food") supply has become a dumping ground for lots of leftover materials and chemicals that would be toxic waste if buried under ground, or that have to be handled under fume hoods and while wearing hazmat suits. As a result, much of the stuff sold from supermarket shelves are made primarily from "ingredients" and not "foods." It even says it on the labels! All foods start out as living things.
Rule of thumb: All foods are ingredients, but not all ingredients are foods. If you can't put a teaspoon of an "ingredient" in your mouth and safely eat it, it's not a food. Chicken is a food. Lettuce, rice, and lard are foods, as is honey, maple syrup, and sugar cane. BHA, however, is not a food, and neither are phosphoric acid, Yellows No. 5 and 6, sodium phosphate, E250, nor caramel color, just to name a few examples. (There is a small group of ingredients, like baking soda--sodium bicarbonate and salt, that you can't do the teaspoon test with, and that do not start out as living things. They usually have dual uses with foods and nonfoods. But they have been around since pre-civilization and our bodies have adapted to them.)
Here's a list of foods eaten all over the world, arranged by food families. (In taxonomy, "family" comes after "class" and it comes before "genus" and "species.") A person with an allergy or sensitivity to a particular food will often have allergies/sensitivities to other foods in the same food family, hence these charts to help understand the possibilities. They are also useful to help people living here in the 21st Century understand some of what actually constitutes food:

People differ in their ability to find healthy foods to incorporate into their diets, but the overall goal is to arrange your life so that as much of what you eat is made up of "food" as possible, while consuming as few (non-food) "ingredients" as possible. Right now, for many people, it's the reverse. Carbonated sodas are about as close to non-food as it gets, but for some people they actually constitute the majority of calories consumed in a day. Some people actually drink them as their only water supply.
Peanut butter: It's a great food, unless you have food allergies. (Try to insure that the peanuts are from a source that's free of aflatoxin, which causes cancer.) Be sure to read the ingredients labels of everything you buy to eat, even if you have safely eaten it before. The only stuff in the peanut butter jar should be peanuts and salt. Even better, get the salt-free kind and add your own sea salt. If there is sugar, high-fructose corn syrup, hydrogenated or partially-hydrogenated fats, or mono- and diglycerides--forget about it. If you want sweet peanut butter, add your own sweet to it. If you want a peanut butter and jelly sandwich, use your own jelly. (In other words, avoid the stuff in the jar with a "swirl" of jelly running through it.)
With this basic peanut butter you have to stir it frequently or it will pack down in the jar. The liquid peanut oil will rise and sit over the carb and protein solids. (This is one reason hydrogenated fats were added to peanut butter--since they stay solid at room temperature, there's less liquid oil to rise, and the peanut solids don't pack down.) It won't be impossible to get out of the jar, but will require some elbow work if it gets packed.
Grass-fed vs. grain-fed beef and milk: Green grasses are the natural foods of cattle. Because grains--the actual seed part of the grass that we call corn, wheat, rice, etc-- are also part the grass, healthy cattle may consume small bits of grain as they eat in pasture. But they get fat if they are fed exclusively or primarily on grains, and that excess fat scatters through the muscles, which is not good for the cow. It's the "marbling" one sees in conventional grain-fed beef cuts. Supposedly this marbling effect leads to more tender and juicy beef, but there are many debates about this.
Grass-fed cattle produce many more CLAs (conjugated linoleic acids) in their meat and milk than grain-fed cattle. I read somewhere that it can be as much as 500% (five hundred percent--that's not a typo) more. CLAs affect the metabolism and immune function of mammals; if you don't get enough CLAs your body undergoes inflammatory processes and you get lots of body fat. CLAs fight this inflammation and may have anti-cancer properties. Because grain-fed cattle tend to get sick more often, they may be fed or injected with all sorts of pharmaceuticals. Most of the antibiotics used in the USA, for example, are fed to livestock, especially cattle, primarily to enhance the fattening effect (a side effect of antibiotics that can happen in humans, too), but also as a prophylactic to deal with infections. It's not just antibiotics, however--another big class on the list are hormones of all kinds, and in dairy cows, there are growth hormones made by genetically-modified organisms.
Bacon: The concern with sodium nitrite is that it forms nitrosamines when heated, browned, or charred, and nitrosamines are known to cause cancer. (Sodium nitrite also causes migraines in some people.)
Early in the 20th Century meat processors added lots of sodium nitrite to meat--it gives it the characteristic red color we've become accustomed to, helps keep the fat from becoming rancid, and makes it harder for microorganisms to grow, particularly the spores that cause botulism. That was before there was widespread refrigeration. Deep freezers for residential use just did not exist, unlike today. It was discovered that sodium nitrite contributed to stomach cancer, a major cause of cancer death in those days. One of the first big drops in cancer incidence in the USA from a science-based change came about when the government mandated that the amount of sodium nitrite in meat be dramatically reduced. That was in the 1920s. Supposedly the incidence of stomach cancer dropped dramatically right after the change.
Nitrites occur naturally in spinach, lettuce, celery, etc. Often in nature, a problematic part of an edible plant will come with a feature that alleviates the problem, if not cancels it outright. (Example: The soluble and nonsoluble fibers in fruits help alleviate the toxic features of fructose.) But spinach, lettuce, and celery are foods (see above), whereas sodium nitrite is not. Still, there are hot dogs, bacons and hams made without any celery or other nitrite source, whether inorganic or natural. Whole Foods carries a bunch of different brands.
Don't forget, before humans began eating pre-cooked, pre-processed, and packaged ingredients, we made good stuff all by ourselves, from food.
