It is true that eating vegetables and fruits helps control weight, but not all vegetables and fruits have the same effect on weight control and reduction. According to the New York Times, the results of a new and detailed study conducted over 24 years by Harvard University show that some vegetables and fruits are more effective in helping control and reduce weight. This study began with over 100,000 men and women in their thirties and forties and followed them for 24 years. Overall, increasing the consumption of vegetables and fruits slows down the process of gaining weight. However, fruits from the blueberry family are more effective than citrus fruits in slowing this process. Additionally, the consumption of carrots and peppers leads to better weight control, while potatoes and peas have no effect on this process. Participants in this study who included starchy fruits and vegetables like potatoes, corn, or peas in their diets showed no signs of weight loss or control, while non-starchy fruits and vegetables—which have more fiber and fewer carbohydrates, such as beans, lettuce, apples, or pears—had a greater impact on weight loss. According to Harvard News, the lead researcher of this study, Dr. Monica Bertoya from Harvard's School of Public Health, states that fruit juice and fried potatoes do not count as fruits and vegetables and should not be considered as part of daily fruit and vegetable consumption. In this context, continuous stress leads to weight gain, dissatisfaction with the body and its consequences, and limited food promises further activate hunger hormones. The Ministry of Health reports that 88% of people in Iran have unhealthy diets. The increase in cancer in low-income countries is attributed to 'following a Western lifestyle.'
