Chances are you already know that eating too much sugar isn’t good for you. Yet you’re probably still overdoing it. Americans average about 270 calories of added sugars each day. That’s about 17 teaspoons a day, compared to the recommended limits of about 12 teaspoon per day or 200 calories.
Sugary drinks, candy, baked goods, and sweetened dairy are the main sources of added sugar. Added sugars may be hard to spot on nutrition labels since they can be listed under a number of names, such as corn syrup, agave nectar, palm sugar, cane juice, or sucrose.
No matter what it’s called, sugar is sugar, and in excess, it can negatively affect your body in many ways. Here’s a closer look at how sugar can mess with your health, from head to toe.
Your Brain
Eating sugar gives your brain a surge of a feel-good chemical called dopamine. That explains why you’re more likely to crave a candy bar at 3 p.m. than an apple or a carrot.
Because whole foods like fruits and veggies don’t cause the brain to release as much dopamine, your brain starts to need more and more sugar to get that same feeling of pleasure. This causes those “gotta-have-it” feelings for your after-dinner ice cream that are so hard to tame.
Your Mood
The occasional candy or cookie can give you a quick burst of energy (or “sugar high”) by raising your blood sugar levels fast. When your levels drop as your cells absorb the sugar, you may feel jittery and anxious (a.k.a. the dreaded “sugar crash”).
But if you’re reaching into the candy jar too often, sugar starts to have an effect on your mood beyond that 3 p.m. slump: Studies have linked a high sugar intake to a greater risk of depression in adults.
Your Teeth
You probably rolled your eyes at age 12, but your parents were right: Candy can rot your teeth. Bacteria that cause cavities love to eat sugar lingering in your mouth after you eat something sweet.
Your Joints
If you have joint pain, here’s more reason to lay off the candy: Eating lots of sweets has been shown to worsen joint pain because of the inflammation they cause in the body. Plus, studies show that people who eat or drink a lot of sugar may be more likely to develop rheumatoid arthritis.
Your Skin
Another side effect of inflammation is that it may make your skin age faster.
Excess sugar attaches to proteins in your bloodstream and creates harmful molecules called “AGEs,” or advanced glycation end products. These molecules do exactly what they sound like they do: age your skin. They have been shown to damage collagen and elastin in your skin — protein fibers that keep your skin firm and youthful. The result? Wrinkles and saggy skin.
Your Liver
An abundance of added sugar likely contains fructose or high fructose corn syrup. Fructose is process in the liver and in large amounts can damage the liver. When fructose is broken down in the liver it is transformed into fat.
Your Heart
When you eat or drink too much sugar, the extra insulin in your bloodstream can affect your arteries all over your body. It causes their walls to get inflamed, grow thicker than normal and more stiff, this stresses your heart and damages it over time. This can lead to heart disease, like heart failure, heart attacks, and strokes.
Your Kidneys
If you have diabetes, too much sugar can lead to kidney damage. The kidneys play an important role in filtering your blood. Once blood sugar levels reach a certain amount, the kidneys start to release excess sugar into your urine. If left uncontrolled, diabetes can damage the kidneys, which prevents them from doing their job in filtering out waste in your blood. This can lead to kidney failure.
Your Body Weight
This probably isn’t news to you, but the more sugar you eat, the more you’ll weigh. Research shows that people who drink sugar-sweetened beverages tend to weigh more — and be at higher risk for type 2 diabetes — than those who don’t. One study even found that people who added more sugar to their diet gained about 1.7 pounds in less than 2 months. Excess amounts of sugar can inflame fat cells causing them to release chemicals that increase weight.
