Years ago, 50 probably, A doctor showed a strong man sitting in his office. The man was asked to hold out his arm and told to resist the doctors push downward. The man held back the doctor. Then the doctor gave the man a spoon full of sugar to put in his mouth and repeated the test.. The man had no resistance at all. Never forgot that video.

I believe the sugar/inflammation correlation. Almost all packaged food is full of sugar. Recent history showing the rise of obesity, diabetes and heart disease should support the theory that sugar and high carb intake are significantly responsible.
