[Dr. Mercola from mercola.com] Limiting sugar in your diet is a well-known key to longevity, because of all the molecules capable of inflicting damage in your body, sugar molecules are probably the most damaging of all. Fructose in particular is an extremely potent pro-inflammatory agent that creates AGEs and speeds up the aging process. It also promotes the kind of dangerous growth of fat cells around your vital organs that are the hallmark of diabetes and heart disease. In one study on fructose, 16 volunteers on a controlled diet including high levels of fructose produced new fat cells around their heart, liver and other digestive organs in just 10 weeks!
Sugar/fructose also increases your insulin and leptin levels and decreases receptor sensitivity for both of these vital hormones, and this is another major factor of premature aging and age-related chronic degenerative diseases such as heart disease. Keep in mind that while it’s perfectly normal for your blood sugar levels to rise slightly after every meal, it is not natural or healthy when your blood sugar levels become excessively elevated and stay that way.
Unfortunately, that’s exactly what will happen if you’re eating like the stereotypical American, who consumes a staggering 2.5 pounds of sugar a week on average!
And when you add in other low-quality carb foods such as white bread, sugar, pasta, pastries, cookies, and candy, which also break down to sugar in your body, it’s not so difficult to see why so many Americans are in such poor health.
This type of high-sugar (high-carb) diet is also what’s driving the obesity epidemic—not diets high in fat. An infographic created by Column Five for Massive Health, based on Why We Get Fat by science writer Gary Taubes, explains why. In short, carbs, like fructose and other sugars, destroy your insulin and leptin sensitivity, which in turn causes your cells to accumulate more fat, and makes it more difficult to get rid of the extra weight as well. So, the bottom line is this: If you want to look and feel younger longer, avoid all forms of sugar (including grains) as much as possible!
