Can eating certain fruits and vegetables help you in your quest for weight loss?
A recent study, published in the journal PLOS Medicine, reveals that a few fruits and vegetables can help maintain or control body weight.
The longitudinal study, conducted at Harvard T. H. Chan School of Public Health and Brigham & Women’s Hospital in Boston and led by Dr. Monica Bertoia, revealed that that certain fruits and vegetables may be more or less beneficial for maintaining or achieving a healthy weight.
The researchers also found that an extra serving of fruit a day can lead to a weight loss of 0.24 kg as compared to the 0.11 kg lost with an extra serving of vegetables during the course of the study.
The research revealed that consuming fruits and vegetable with a higher fibre content or lower glycemic load – a number that estimates how much the food will raise a person’s blood glucose level after eating it – would be more likely to lead to a healthy weight than consumption of those with a lower fibre content or higher glycemic load.
More than 70 items were included in the study, with care taken to include fruits and vegetables with similar nutritional values such as apples and pears. The fruit categories included citrus, melon, and berries; vegetables were classified into cruciferous, green leafy, and legumes.
All fruits and vegetables were classified as high or low fibre, and as high or low GL. This was calculated by multiplying the carbohydrate content of each fruit/vegetable (grams per serving) by the glycemic index of that fruit/vegetable.
