Share this with everyone you know, I'm going to save a lot of lives:
Diabetes is not caused by sugar, it is caused by junk food (sausage, bacon, McDonalds and whatever goes into THAT kind of food).
Sugar alone has no nutrition but it is NOT bad. White / cane sugar (sucrose), fructose are harmless. Lactose (milk) is harmless too, people aren't intolerant you just can't drink it cold (heat it up and you can drink a lot). Starch is the most harmful 'okay' sugar but not bad.
Brown sugar, wheat and all the 'hard to digest' sugars/carbs are bad. They sit in your stomach and bacteria feeds off of it.
The priority with food is this:
#1) It must not be bad for me (poisonoius)
#2) It must be nutritional
That's it. 'Junk food' is food that doesn't fulfill #1. PURE WHITE SUGAR is not bad, but it has no nutrition. PURE BROWN SUGAR is bad, it comes from wheat and it has no nutrition, it also slows the metabolism. White rice > brown rice. You don't want food that slows metabolism or worsens stomach bacteria, that is the easiest way to get disease.
Milk is good because it fulfills #1 and it has almost all nutrients, but it is bad to drink full fat milk since fat is unecessary.
Fat is bad in large quantities. Polyunsaturated fat should be avoided (nuts, seeds, most oils except coconut oil which also speed metabolism)
Protein is essential but beef is better than chicken/turkey because cows are ruminant animals. This means any bad food that cows are fed will not effect you, but if you eat a chicken fed a poor diet you will basically eat its diet yourself.
If you eat meat and it has iron, iron is bad for you so eat it with caffeine so it is inhibited.
Too many vegetables and grains are bad for you because they inhibit calcium absorption.
Cigarettes (nicotine) are okay once in a while. Good for you for similar reason to caffeine.
There is more, I learned this all from Ray Peat.
