The belly rules the mind. ~ Spanish proverb
It is astonishing that nutrition can be a controversial subject. It remains so because of widespread ignorance.
Simply, the best diet consists entirely of organic vegan produce: a variety of fruits and vegetables, with a smattering of seeds (nuts, grains, and legumes).
A healthy diet is high in carbohydrates, with a modest amount of protein, and the fat found in otherwise nutritious fruit, such as nuts and avocado.
Eating the right kinds of difficult-to-digest food – dietary fiber – is essential to health. This seems something of a paradox. It is instead sharing the wealth.
The gut flora that digest what we eat need sustenance. If microbes in the stomach cannot consume all that comes to them, those in the lower tract have something to chew on. Otherwise these lower denizens starve, and the digestive system suffers.
For healthy digestive microbial communities throughout the digestive tract, dietary fiber, such as resistant starch, must be eaten. Resistant starch comprises carbohydrates that pass through to the large intestines undigested. Many natural foods contain resistant starch.
From a health standpoint, the term vegetarian is an oxymoronic combination: vegan (fruits, vegetables, and seeds) and dairy. Dairy clogs the system with its excessive protein and unseemly fat. It gives an otherwise healthy diet a bad name. Veganism is the healthy choice. Vegetarianism is not.
Meat, especially mammal flesh, presents serious digestive difficulty. Its regular consumption accelerates aging.
Nominally healthy seafood has been seriously polluted by worldwide industrialization. Fatty fish, such as tuna, have become more toxic than nutritious.
What most people eat – processed foods – barely sustains the body. What tickles the taste buds for so many, while doing the most damage, is sugar and its artificial substitutes.
