why is too much sugar bad for your health
In order to understand what is so bad about sugar, then you need to understand what it is made of. Before sugar enters the bloodstream from the digestive tract, it is broken down into two simple sugars. glucose and fructose. Glucose is found in every living cell on the planet. If we don t get it from the diet, our bodies produce it. Fructose is different. Our bodies do not produce it in any significant amount and there is no physiological need for it. The thing with is that it can only be metabolized by the liver in any significant amounts. This is not a problem if we eat a little bit (such as from fruit) or we just finished an exercise session. In this case, the fructose will be turned into glycogen and stored in the liver until we need it (
). However, if the liver is full of glycogen (much more common), eating a lot of fructose overloads the liver, forcing it to turn the fructose into fat ( ). When repeatedly eating large amounts of sugar, this process can lead to fatty liver and all sorts of serious problems ( ).
Keep in mind that all of this does NOT apply to. It is almost impossible to overeat fructose by eating fruit. There is also massive individual variability here. People who are healthy and active can tolerate more sugar than people who are inactive and eat a Western, high-carb, high-calorie diet. Bottom Line: For people who are inactive and eat a Western diet, large amounts of fructose from added sugars get turned into fat in the liver. 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. б If you have joint pain, hereБs 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, studiesб show that sugar consumption can increase your risk of developing rheumatoid arthritis. Another side effect of inflammation: It may make your skin age faster. Sugar attaches to proteins in your bloodstream and creates harmful molecules called БAGEs,Б 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. б The result? Wrinkles and saggy skin. An abundance of added sugar may cause your liver to become resistant to insulin, an important hormone that helps turn sugar in your bloodstream into energy. This means your body isnБt able to control your blood sugar levels as well, which can lead to type 2 diabetes. б When you eat excess sugar, the extra insulin in your bloodstream can affect your arteries, part of your bodyБs circulatory system.
It causes their walls to grow faster than normal and get tense, which adds stress to your heart and damages it over time. This can lead to heart disease, heart attacks, and strokes. Researchб 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. б б When you eat, your pancreas pumps out insulin. But if youБre 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. б
