So was mine. Then, I was diagnosed with type 2 diabetes. After years of cavalierly treating it, I became depressed, irritable and it almost cost me the things I hold dear.
After much research, and the help of a family member who is a doctor, I slowly came to realize that it is the foods we eat today that are causing a multitude of problems, including the epidemic of type 2 diabetics, mostly related to how the body processes sugars, and how the body utilizes insulin.
My doctor relative is even more convinced now that diet plays a much larger role in the ills of society tody than we ever thought.
If one looks at things like crime increases, and anti-social behavior increases, you can see that the timeline coincides with the introduction of "fast foods" of various kinds.
Hormonal imbalances caused by these foods also may be responsible for the 'they didn't make girls like that when I was in school' observation. In fact, they didn't. But hormonal changes brought on by food additives and processes seem to be causing puberty and accelerated growth stages in our youth, with all of the attendant problems that causes.(girls and boys in adult bodies)
Nowadays, having a garden to grow your own produce may be a vital means of self defense.
Have cut my own "impacting" carbs down to around 30-40 grams a day, about ten percent of what's recommended on the AHA food pyramid. Attained my weight goal six months ago. I used to be famished by ten in the morning, and sleepy by three in the afternoon. No more... The Heart Association has turned us into a nation of rolypoly diabetics, and they have the nerve to blame video games...
I suspect diabetics are also consuming too many carbs. I've looked into using foods designed for diabetics and they are too high in sugars/starches.
