Why Sugar Is Bad for Your Health

Unstable blood sugar can leave you experiencing mood swings, fatigue, and headaches. It also contributes to cravings, which begins the cycle of false hunger. By contrast, those who avoid sugar report having fewer cravings while feeling more emotionally balanced and energized.

While we all like to indulge once in a while, foods that quickly affect blood sugar contribute to a greater risk of obesity, heart disease, and diabetes.1 Emerging research also suggests connections between these high-glycemic diets and various forms of cancer. These effects are often a result of added sugars working in your body, so be sure to read those nutrition labels.

As if being sick wasn’t bad enough, studies have shown that sugar can interfere with the way your body fights disease. Bacteria and yeast feed on sugar, so excess glucose in the body causes these organisms to build up and cause infections.

Chromium, a trace mineral, helps regulate blood sugar in the body. While it can be found in meats, seafood, and plant foods, 90% of Americans still don’t get enough chromium because of refining starches.6 Other carbohydrates can also rob foods of their chromium supplies, so limiting your carbs is your best bet for increasing those mineral levels.

While you probably know that sugars can affect your body composition, they can also mess with your skin by contributing to wrinkles and sagging. After sugar hits your bloodstream, it attaches to proteins. The mix of these proteins with sugar causes the skin to lose elasticity and leads to premature aging.

With all the other life-threatening effects of sugar, we sometimes forget the most basic cosmetic damage it does. When it sits on your teeth, sugar causes decay more efficiently than any other food. It’s important to brush your teeth at least twice a day to stop sugars from fueling plaque and bacteria.

Increasing evidence shows that chronic infections, like those that result from dental problems, play a role in the development of heart disease. Most researchers believe that the connection stems from the body’s inflammatory response to infection. Luckily, this works both ways. Maintaining a healthy lifestyle will decrease your risk of common illnesses, which reduces the chance that they’ll become a more serious condition later on.

Let’s not forget about our little ones! When New York City public schools reduced the amount of sugar in their lunches and breakfasts, their academic ranking increased 15.7% (previously, the greatest improvement ever seen had been 1.7%).11 The study also eliminated artificial colors, synthetic flavoring, and two preservatives, showing the importance of natural ingredients for children.

When we’re under stress, our bodies immediately kick into fight-or-flight mode, releasing large amounts of hormones. Surprisingly, the body has the same chemical response when blood sugar is low. After you eat a sweet snack, stress hormones begin to compensate for the crash by raising your blood sugar. The result? Unexplained anxiousness, irritability, and even shakiness.
