There is a lot of ambiguity about what the recommended diet is, so most people mistakenly believe that their diet is satisfactory, even though it is not.
The diversity of diets, supplements, and a wide range of products (primarily industrialized) makes choosing a personal and family diet challenging. Consistently, people think they are eating healthy food. On closer inspection, it turns out that this is not the case! The explanation for the phenomenon stems from the ambiguity of the whole subject of nutrition science, which does not have an agreed and precise methodology. Everyone has the right to name the diet after them and advertise and market it.
The article in the link below describes the balanced-varied diet. It attempts to establish the principles and rules for an optimal diet that can serve most of the population, including chronic patients. (With minor changes)
- Primary principles of the balanced-varied diet - Much unprocessed natural food (preferably organic and not genetically modified) contains all macronutrients and ingredients—reduced quantities of animal protein, preferably grass-fed or organic range-free products. Many dietary fibers are mixed with natural oils & fats that enable an effective emulsification process. Fermented products with natural live bacteria are essential for good health. Vegetables, fruits, seeds, sprouts, roots, legumes, mushrooms, beans, berries, and nuts should be very high-volume diet components.
