Comment on Why very high fruit diets are a *disaster* for most of us by Richard.
This article is well written but is based in an incomplete understanding of metabolism. Firstly a diet high in sugar does cause insulin spikes, but so does a meal high in protein. Protein spikes insulin regardless if sugar or carbohydrate is present. So any meal you eat (unless it is a meal of pure fat) will significantly increase insulin. Whey protein for instance increases insulin as much or more than some carbohydrate meals. Next sugar does not turn to fat, unless certain conditions are met. It would be safe to say that most body fat actually comes from dietary fat. Next fruit based diets do have certain deficiencies. Most of these can be compensated for with a diet that contains lots of nutrient dense meals made with bone broth, liver, grass fed milk, meat, cheese, eggs, and well cooked greens, herbs and spices. Presently I obtain most of my calories from sugar from fruit, milk, and honey, I also eat pastas and other starches. The real problem is PUFA (polyunsaturated fats) which damages the organs, upsets hormone levels, causes inflammation, oxidation, promotes cancer and ultimately leads to disease.
