Americans’ eating habits have improved – except among the poor, evidence of a widening wealth gap when it comes to diet. Yet even among wealthier adults, food choices remain far from ideal, a 12-year study found.
On an index of healthy eating where a perfect score is 110, U.S. adults averaged just 40 points in 1999-2000, climbing steadily to 47 points in 2009-10, the study found.
Scores for low-income adults were lower than the average and barely budged during the years studied. They averaged almost four points lower than those for high-income adults at the beginning; the difference increased to more than six points in 2009-10.
Higher scores mean greater intake of heart-healthy foods including vegetables, fruits, whole grains and healthy fats, and a high score means a low risk of obesity and chronic illnesses including heart disease, strokes and diabetes. Low scores mean people face greater chances for developing those ailments.
The widening rich-poor diet gap is disconcerting and “will have important public health implications,” said study co-author Dr. Frank Hu of the Harvard School of Public Health. Diet-linked chronic diseases such as diabetes have become more common in Americans in general, and especially in the poor, he noted.
