"New research on aging suggests that carbohydrates influence two key genes that directly affect longevity and youthfulness"

"Carbohydrates (glucose) directly affect the genes that govern youthfulness and longevity! So, you may actually be able to extend your life and stay fit throughout your old age with a simple dietary change that switches on your “youth” gene."

"Animal studies have shown a relationship between carbohydrate intake and aging, or more precisely, a relationship between the hormones that are activated by carbohydrates and aging."

"A low carb diet is likely to be very, very good for you if:
* You carry your fat disproportionately on your abdomen
* You are hungry within 60 - 90 minutes of eating carbs
* You have serious energy slumps -- especially slumps that happen at a predictable time every day"

"Over the years, studies have found that restricting calories slows aging and increases longevity—however the mechanism of this effect has remained elusive,” Verdin said in a statement. “Here, we find that βOHB—the body’s major source of energy during exercise or fasting—blocks a class of enzymes that would otherwise promote oxidative stress, thus protecting cells from aging.”

"Menopause and perimenopause, the 5-10 year period preceding it, often result in decreased insulin sensitivity, particularly in those predisposed to endocrine imbalances. Recent research indicates that decreasing levels of estrogen lead to insulin resistance and impaired carbohydrate tolerance even among nonobese menopausal women. Weight gain during perimenopause and menopause is  an obvious result; it's difficult to ignore your pants getting tighter even if you're not weighing yourself regularly. What many  women are less aware of (unless they're testing with a glucometer) are elevated blood sugar levels after eating."

"First, to get any anti-aging properties from our diet, we must know what food to avoid. The single biggest culprit that causes aging and the appearance of aging is sugar. This doesn't mean just the white granulated stuff in your canister on the counter either. High fructose corn syrup is even worse for the body than sugar, because it has the same negative effect on insulin in the body as well as having the negative effects that corn itself can cause for aging the body."

"Fructose has been hypothesized to cause obesity ^[2], elevated LDL cholesterol and triglycerides, leading to metabolic syndrome. Unlike animal experiments, some human experiments have failed to show a correlation between  fructose consumption and obesity. Short term tests, lack of dietary control, and lack of a non-fructose consuming control group are all confounding factors in human experiments. However, there are now a number of reports showing correlation of fructose consumption to obesity, especially central obesity which is generally regarded as the most dangerous type."

"Carbohydrate is the main killer in the average Western diet, not fat. Eskimos and other aboriginal people with very high fat levels in their diet do not suffer degenerative artery disease in the way we do in the civilized world. However misinformation and ignorance abounds. Whatever science you read extolling the supposed benefits of carbohydrates, this will always refer to complex carbohydrates (meaning whole grains). This also overlooks the fact that many people are intolerant to grains. Despite all the propaganda, even whole grains are not “natural” foods at all. Man evolved as a hunter gatherer and grains have only been in our diet for the last 10,000 years or so. Many people cannot digest grains but get unpleasant reactions."

Cross-sectional studies indicate that diets that provide a higher dietary glycemic index (dGI) are associated with a greater risk of age-related macular degeneration (AMD).
