In my opinion… it is not enough to eat healthy foods, but we should add herbs and maybe checking that the food that is eaten is as organic as possible, and that there are no unnecessary spraying or… grow some of your food in your garden or on your balcony.
Recently I investigated the subject and came to an interesting book The Lost Book of Remedies, how to find them and how to grow on your own for batter health..

Difficult to understand how early man survived without access to the wide range of foods suggested. Our ancestors did not have the ability to, “combine healthy choices from across all food groups.” Our ancestors were not at one with nature. Nature tried to kill them and starve them out; they survived anyway, sometimes with more meat, sometimes with less, thanks in part to the ancient flexibility of our guts. it has been suggested that our shift to eating more meat historically might have allowed investment in bigger brains which might, in turn, have required us to eat more meat so as to feed the bigger brain and simultaneously made our large intestines and their fermentation less necessary. In summary, our bodies are all fully-equipped to deal with meat and natural sugars , and harder to digest plant material. I prefer to eat seafood and some red meat., and some fruit.

I wonder how true these “truths” still are…given the level of mercury and plastics in sea water, how much pesticides, fungicides, sprayed on our produce.

Does drinking hazelnut coffee without cream or sugar contribute to a healthy diet?

I believe Dr. Steven Gundry in Plant Paradox is totally correct in his elimination of whole grains, tomatoes (and other nightshades) and legumes from a healthy diet…too many gut damaging lectins, mainly in the bran of wheat and rice.

Is there any proven strategy for attracting YOUNG adults to this site?
They are the least informed group of consumers when it comes to eating healthy. It is imperative that we reach this demographic if we are to
save the human race from ever more man-made diseases promulgated
by by-products of plastics in our foods.

Great food choices. Can fermented porridge offer the good bacteria for those who do not consume dairy milk?

Some farmed salmon has far higher levels of PCBs then wild caught fish. Because many farmed salmon are, like all ‘farmed’ animals kept in large numbers in way too small of spaces, pesticides and antibiotics are used to keep disease/pest levels down. Not so with wild salmon. Sea lice are a big problem w/farmed salmon, yet another pesticide must be added to the farmed salmon environment to control those sea lice. It’s rare for wild salmon to have a problem/overload of sea lice.

PCDBs are found in the feed of farmed salmon, these are flame retardants that have become almost ubiquitous in the environment but are found in at far higher levels in farmed then wild caught salmon.
These chemical compounds are endocrine disruptors.

Not all fish, not even all salmon are equally nourishing or a “superfood.”

As for vegetables & fruits, I’d check the Environmental work group for which fruits, veg, legumes and whole grains are best to buy organically grown and which are fine if you buy conventionally grown. It’s smart o limit your and your family’s exposure to pesticides and herbicides. Doesn’t hurt to support methods of farming that best protect the environment either as long as you can afford to. Those who have the space & time or access to community garden space, might want to try growing some of their own veg/fruit. Fresh ripe tomatoes, etc. usually taste the best.
