High-fructose corn syrup is the principal sweetening agent in most high-sugar soft drinks. Fructose provides the sweet taste in fruits. In sedentary people, it is linked to an increased risk of the metabolic syndrome (abdominal obesity, abnormal blood fats, high blood pressure, poor blood sugar regulation, inflammation and blood-clotting abnormalities). People consume about 300 more calories per day more than they did 30 years ago, largely because of an increased intake of fructose. A report published in Current Sports Medicine Reports, stated that a high fructose intake was beneficial for athletes. Fructose stimulates the digestion and promotes carbohydrate used during exercise, which are important for optimal performance. Intense training involves high energy expenditure, which protects athletes from the negative effects of fructose experienced by sedentary people.
