Sugar

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 Pancreas

When you eat, your pancreas pumps out insulin. But if you’re eating way too much sugar and your body stops responding properly to insulin, your pancreas starts pumping out even more insulin. Eventually, your overworked pancreas will break down and your blood sugar levels will rise, setting you up for type 2 diabetes and heart disease.

Your Heart

When you eat excess 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. Research also suggests that eating less sugar can help lower blood pressure, a major risk factor for heart disease. Plus, people who eat a lot of added sugar (where at least 25% of their calories comes from added sugar) are twice as likely to die of heart disease as those whose diets include less than 10% of total calories from added sugar.

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. In turn this causes:

Non-alcoholic fatty liver disease (NAFLD): This is seen as excess fat build-up in the liver.
Non-alcoholic steatohepatitis (NASH): is a fatty liver, inflammation and "steatosis," which is scarring of the liver. Scarring eventually cuts off blood supply to the liver. Many of these develop into cirrhosis and will need a liver transplant.

Your Teeth

You probably rolled your eyes at age 12, but your mother was 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 sugar consumption can increase your risk of developing rheumatoid arthritis.

Your Skin
Another side effect of inflammation - 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 elastic in your skin -- protein fibers that keep your skin firm and youthful. The result? Wrinkles and saggy skin.
