Eating more fruits and vegetables can help control weight, but a new study suggests that it depends on which fruits and vegetables you eat.
Researchers recorded diet information for 117,918 men and women in their 30s and 40s at the start of a study and followed them for 24 years, with interviews at four-year intervals.
An overall increase in a daily serving of vegetable or fruit over a four-year period led to less weight gained — 0.25 pounds less for vegetables, and 0.53 pounds for fruit.
Increased intake of berries was linked to a 1.11-pound lower weight gain, and of citrus fruits a 0.27-pound lower gain. Adding a daily serving of tofu or soy was tied to 2.47 pounds less weight gained, and of apples or pears 1.24 pounds less. Carrots and peppers were also linked to smaller gains, but potatoes, peas and corn were not.
The study, in PLOS Medicine, controlled for many health and behavioral variables, including changes in dozens of food and nutrient intakes apart from fruits and vegetables.
The lead author, Monica L. Bertoia, a researcher at the Harvard T.H. Chan School of Public Health, said that Americans’ fruit and vegetable intake was mostly fruit juices and potatoes. But, she said, “There are many fruits and vegetables that may be better choices — apples, pears, berries and nonstarchy vegetables.
