1. Sugar leads to rise in blood glucose

Sugar leads to rise in blood glucose

Unstable blood sugar causes mood swings, fatigue, headaches and cravings for more sugar. Cravings set the stage for a cycle of addiction in which every new hit of sugar makes you feel better temporarily but, a few hours later, results in more cravings and hunger. On the contrary, those who avoid sugar often report having little or no cravings for sweet things and feeling balanced and energized.

2. Sugar increases the risk of heart disease.

Sugar increases the risk of heart disease

Large-scale studies have shown that the more high-glycemic foods (those that quickly affect blood sugar), including foods containing sugar, a person consumes, the higher his risk for obesity and for developing diabetes and heart diseases.

3. Sugar increases stress.

Sugar increases stress

When we’re under stress, our stress hormone levels rise; these chemicals are the body’s fight-or-flight hormones that prepare the body for facing any situations. These chemicals are also called when blood sugar is low. For example, after a blood-sugar spike (say, from eating a piece of birthday cake), there’s a compensatory dive, which causes the body to release stress hormones such as adrenaline, epinephrine and cortisol. One of the major effects of these hormones do is raise blood sugar, providing the body with a quick energy boost. The problem is, these helpful hormones can make us feel anxious, irritable and shaky.

4. Sugar interferes with immune function.

Research on human subjects is scant, but animal studies have shown that sugar suppresses immune response. We know that bacteria and yeast feed on sugar and that, when these organisms get out of balance in the body, infections and illness are more likely.

5. Sugar accelerates aging.

Sugar accelerates aging

It even contributes to sign of aging: sagging skin. Some of the sugar you consume, after hitting your bloodstream, ends up attaching itself to proteins, in a process called glycation. These new molecular structures aid to the loss of elasticity that ocur in aging body tissues, from your skin to your organs and arteries. The more sugar circulating in your blood, the faster this damage takes hold.
