As I've pointed out before, carbohydrate foods are not necessary. Particularly because a carb is only an energy food, yet protein and fat are energy + muscle maintenance and repair, support organ and bone health, and you can not live without them. On the other hand, you can live without sugars and grains. You can thrive on a diet of low carbs and high protein and fat.

Carbohydrate foods force your pancreas to pump out insulin and shuttle nutrients to greedy fat cells, thus starving our organs and organ systems of much needed nutrients. Sugar spikes and insulin driven storage of nutrients results in insulin resistance and diabetes with myriad of health consequences.

But hold on, there's more...

Carbohydrates lower one's levels of health promoting testosterone! Check out this new study:

Past research shows that a high level of insulin, the hormone primarily secreted after eating, is related to low testosterone levels. Like eating, glucose intake causes blood glucose (sugar) levels to rise, which stimulates secretion of insulin. Hayes and her colleagues examined the impact of a standard dose of glucose on testosterone levels in 74 men. The researchers administered the oral glucose tolerance test, a screening test for diabetes that involves drinking a sugary solution (75 grams of pure glucose) and then measuring blood sugar levels.  

Of the 74 men, 42 had normal glucose tolerance on the test, 23 had impaired glucose tolerance (also called prediabetes) and 9 had newly diagnosed type 2 diabetes.

The authors found that the glucose solution decreased blood levels of testosterone by as much as 25 percent, regardless of whether the men had diabetes, prediabetes or normal glucose tolerance.

Two hours after glucose administration, the testosterone level remained much lower than before the test in 73 of the 74 men, a statistically significant difference, the authors reported. Of the 66 men who had normal testosterone levels before the test, 10 (15 percent) became hypogonadal at one or more time points during the test.

The results did not differ by changes in insulin levels, according to the abstract. Other hormones that could change testosterone measurements also did not appear to affect results. Hayes said more research is needed to find the factor or factors responsible for this drop in testosterone.
