Sugihiro T, et al. – Researchers investigated the link between Westernized dietary habits and the development of obesity or diabetes in this study involving 765 Japanese Americans with normal glucose tolerance at baseline who were stratified at baseline as “lean” (n=576 individuals; body mass index < 25 kg/m²) or “obese” (n=189; body mass index of ≥ 25 kg/m²). A positive association of diabetes development with consumption of animal protein, animal fat, and saturated fatty acid was observed among 36 obese participants who developed diabetes. Obesity developed in 85 lean participants, and was found to be positively related to consumption of simple carbohydrates, sugar, and fructose, and showed inverse associations to consumption of vegetable protein and complex carbohydrates (mean follow-up period: 10.4 ± 6.5 years). Overall, the development of obesity and diabetes in Japanese Americans was influenced by different nutrient intakes. Based on the presence or absence of obesity, variations were noted in the associations of nutrient intakes with diabetes development.
