Researchers analyzed data from 11 populations of adults totaling nearly 400,000 men and women, finding no correlation between refined grain intake and the risk of developing type 2 diabetes. In contrast, total grain intake was consistently associated with a lower risk of T2D.
A recent study found that eliminating enriched refined grain foods from the American diet results in lower nutrient levels, particularly for dietary fiber, iron, and magnesium. The removal of these grains also leads to a reduction in energy intake by approximately 10% in both age groups.
A comprehensive analysis of data on nearly two million adults found that high-glycemic foods are neither more nor less likely to lead to weight gain than low-glycemic foods. The study suggests that carbohydrate quality, rather than glycemic index, is a more important factor in determining body weight.
The study found that infants who consumed grains had higher nutrient intakes, better diet quality scores, and broader food group intake. Grains were associated with greater daily dietary fiber, iron, zinc, magnesium, phosphorus, folate, riboflavin, niacin, thiamin, vitamin A, vitamin B6, and vitamin B12 compared to non-consumers.
