Added sugars, like high fructose corn syrup and sucrose, contains a lot of calories with no essential nutrients. That’s why they’re called empty calories.
There are no proteins, essential fats, vitamins or minerals in sugar – only calories.
Sugar is the leading contributor to obesity in both adults and children. People who consume a lot of sugars are more likely to become obese, and this applies to all age groups.
Sugar is very easy to overeat. Some nutrients make us feel fuller for longer, therefore we eat less within a 24 hr period. Protein and fiber are known for their satiating properties, but sugar isn’t. In fact, foods and drinks high in added sugar are extremely easy to over-consume. Sugar-sweetened beverages are the worst because even though they’re high in calories, your brain doesn’t register them like solid food. So you won’t eat less food to compensate for those calories.
Sugar can contribute to insulin resistance, that can cause serious metabolic problems. Insulin is a very important hormone when it comes to weight loss. It allows blood glucose (blood sugar) to enter cells to be utilized for energy. Too much glucose left in the blood can cause complications, like diabetes, kidney damage or blindness.
Insulin resistance is when cells become resistant to insulin which means it stops working as it should. Insulin resistance is believed to be the major cause for metabolic diseases.
Sugar also causes tooth decay. When we eat sugar, the harmful bacteria in the mouth can use it for energy. This allows them to grow, multiply and secrete acids that erode the protective enamel of the teeth. Sugar alcohols are popular alternatives that may help protect the teeth.
What you can do if you would like to lose weight is to cut back on added sugars in your drinks and foods. If you miss the sweet taste, you can use certain natural sweeteners to cure your cravings.
