Past research suggests that overloading on sugar can increase your blood pressure, triglycerides levels and inflammation in your body – all precursors to cardiovascular disease, the study authors say.
2. Too much sugar might make you break out more
Foods with a high glycemic index (GI) ranking – which is based on their potential to spike your sugar levels – may be behind your pesky breakouts, according to the American Academy of Dermatology.
High GI foods are generally higher in added sugars or refined carbs, and include things like white bread, white rice, potato chips and ice cream. While a lot more research needs to be done to understand the complex relationship between your diet and acne, multiple studies have found that following a low-GI diet may help improve your skin, according to a review published in the Journal of Clinical and Aesthetic Dermatology. Why? Higher sugar levels leads to more production of the hormone insulin, which in turn, increases sebum, or oil, production in your skin.
Eating a diet rich in low-GI foods – like whole grains, fruits and vegetables, which don’t cause as big a blood sugar spike – may actually reduce the size of your oil glands and decrease inflammation in your skin, the review concluded. And that can mean smoother skin.
3. Too much sugar makes your belly bigger
Unsurprisingly, sugary foods pack on the kilos – so much so that sugar has been identified as one of the main culprits behind America’s obesity epidemic. In fact, in a meta-analysis of 68 trials and studies, researchers concluded that people who ate however they wanted typically weighed more when they loaded up on sugar and less when they didn’t consume as much.
Why? Sugary drinks don’t keep you feeling full like naturally sweet foods do, so you’re more likely to go overboard with a sweetened beverage, which, of course, packs in the extra kilojoules. And sugary foods (we’re looking at you, delicious chocolate chip cookies) are typically higher in kilojoules than the more nutrient-dense stuff, the researchers say.
