Yamakawa M, Wada K, Koda S, et al. - In this prospective cohort analysis, researchers investigated the relationship between alterations in weight and the consumption of different carbohydrate types—including starch, total sugars, and free or naturally occurring sugars and saccharides (ie, glucose, fructose, sucrose, and lactose)—among 13,229 Japanese men (n = 5,879) and women (n = 7,350) aged 35–69 years. These participants took part in the surveys performed in 1992 and 2002. People with cancer, coronary artery disease, stroke, or diabetes on the first survey and those without data regarding body weight on both surveys were excluded. Among Japanese men, long-term weight gain was observed in relation to high intakes of free sugars, sucrose, and fructose. Among women, there was no significant link between consumption of any type of carbohydrate and weight change.
