(Reuters) – Native Americans who often ate processed meat in a can, generically known as “spam” and a common food on reservations, one subsidized (trợ giúp, trợ giá) by the government — had a two-fold (2 lần) increased risk of developing diabetes (phát bệnh tiểu đường) over those who ate little or none, according to a U.S. study.
Native Americans are at especially high risk of developing diabetes, with nearly half having the condition (bị bệnh này) by age 55.
Researchers writing () in the American Journal of Clinical Nutrition surveyed (khảo sát) 2,000 Native Americans from Arizona, Oklahoma and North and South Dakota to look into (xem xét) potential reasons (các nguyên nhân khả dĩ ) for the high rate.
“A lot of communities in this study are in very rural areas with limited access to grocery stores (các cửa hàng bán lẻ thực phẩm nhỏ)… and they want to eat foods that have a long shelf life,” said Amanda Fretts, the lead author and a researcher at the University of Washington School of Medicine.
None of the survey participants, whose average age was 35, had diabetes at the start of (vào lúc bắt đầu) the study when they answered questions about diet and other health and lifestyle factors.
After five years, a follow-up survey found that 243 people had developed diabetes.
Among the 500 people in the original study group who ate the most (ăn .. nhiều nhất) canned processed meat, 85 developed diabetes. In contrast, among the 500 people who ate the least amount of “spam,” just 44 developed the disease.
Though Spam is a brand-name pork product, the lower-case term is also used to describe any kind of processed, canned meat, Fretts said. Canned meat is available freely (dễ dàng) to many Native Americans on reservations as part of the U.S. Department of Agriculture’s food assistance program (chương trình hỗ trợ thực phẩm).
Fretts and her colleagues found that unprocessed (không qua chế biến) meat did not have the same relationship with diabetes, with people equally likely to develop diabetes regardless of how much hamburger or cuts of pork (lát thịt heo) or beef they ate.
Fretts và các cộng sự thấy rằng đối với những người có cùng khả năng bị tiểu đường, thực phẩm thịt không qua chế biến không có tương quan ảnh hưởng với bệnh này dù họ có ăn nhiều hay ít hamburger, thịt heo hay thịt bò
“I think what this study indicates is processed meats should be a priority for reduction (một sự tiết giảm cần ưu tiên) in the diet, especially among American Indians where they can go to food assistance programs and they can get discounted spam (thịt giảm giá),” said Dariush Mozaffarian, a professor at the Harvard School of Public Health who was not involved in the study.
Mozaffarian and his colleagues two years ago conducted an analysis that found that processed meats were tied to (có liên quan, gắn liền với) a 19 percent higher diabetes risk, while unprocessed meats were neutral (trung tính).
“I think the biggest difference between processed and unprocessed meats is sodium (natri),” he said, though he added that there is no clear explanation for the link of (mối quan hệ) processed meats and diabetes.
Fretts and her colleagues noted that the people who ate the most processed meats tended also to be heavier, with larger waistlines (vòng bụng lớn hơn), raising the possibility (gia tăng khả năng) that processed meats contribute to obesity (béo phì), which raises the risk (làm tăng nguy cơ) of diabetes.
In an emailed (gửi đi bằng email) statement to Reuters Health, The American Meat Institute, which represents companies that process meat, said that “processed meats are a safe and nutritious part of a balanced diet.”
Fretts said the study could not prove that eating processed meats was to blame for (quy kết là nguyên nhân) the increased risk of diabetes.
“I think there needs to be more follow-up (cần có nhiều sự theo dõi tiếp tục),” she said.
