You can prevent it NOW...by rejecting the very wrongheaded dietary guidelines that created the “crisis” to begin with. Eat avacados, coconut and olive oils, butter, eggs (WITH yolks). Avoid sugars, excessive carbs, margarine, pesticides. Avoid “low fat” diets in favor of low carb and low sugar diets.
Our brains are fat fed. I have low blood sugar and my brain is the first sign. I can’t eat sugar so I eat fat.
I believe it is stress that causes the problems.
