Dietary Fiber Intake and Depression Symptoms May be Linked
While depression is a psychological illness, there may be physical causes and connections as well. A recent study suggests that dietary fiber consumption may be inversely related to depression symptoms.
For this study, researchers examined data from the National Health and Nutrition Examination Survey, which took place from 2007 to 2014 and included the dietary habits and nutritional status of more than 16,000 Americans.
After examining the data, they found that people who consumed 21 grams of fiber per day were less likely to exhibit depression symptoms than those who consumed less. They also found that the average intake was only 15 grams per day, suggesting that more fiber might be a good recommendation for people prone to depression.
Researchers from Qingdao University in China conducted the study. It was published in the October 2018 issue of Nutrition.
There are two types of fiber: soluble and insoluble. Soluble fiber can be found naturally in oats, peas, beans, apples, citrus fruits, carrots, barley and psyllium. Insoluble fiber can be found in whole wheat and grains, brown rice, fruit, broccoli, cabbage and dark leafy vegetables.
