Research indicates that there is a positive correlation between consumption of high fructose corn syrup and obesity percentages. Sucrose is the leading added sweetener in in the manufacture of foods in the Unites States and is the biggest source of fructose. Sucrose and high fructose corn syrup (HFCS) are metabolized identically and react the same way to insulin‚ leptin and ghrelin. Sucrose is indifferent from HFCS in causing obesity.
