New research shows increasing your intake of fresh fruits and vegetables can boost your well-being in as little as two weeks. Although the study didn’t explain why, previous studies show eating more vegetables impacts brain, immune, and gut health — all of which affect your mood.
The New Zealand study divided more than 170 young adults into three groups. The researchers personally gave one group two servings on fresh fruits and vegetables each day. The second group was given vouchers and text reminders to consume extra produce. The third group was not given any produce or vouchers.
The first group given the extra produce in person consumed an average of 3.7 servings a day of fruits and vegetables. After two weeks they reported feeling improvements in mood, vitality, motivation, as well as a flourishing of well-being.
The other two groups reported no change.
5 ways eating more produce makes you feel better
When you look at the effects of a plant-based diet on health, the results of this study are no surprise.
Here are five reasons why eating more fruits and vegetables can make you happier and more motivated:
Eating more vegetables increases the gut bacteria that promotes relaxation. Brain scans show healthy gut bacteria promotes relaxation.
Eating more vegetables increases the gut bacteria that lower brain inflammation. A Harvard-affiliated study found that healthy gut bacteria lowers brain inflammation, thus lowering the risk of dementia. Brain inflammation is also linked with depression, anxiety, and irritability.
Eating more vegetables increases the gut bacteria that lower depression, anxiety, eating disorders, autism symptoms, and obesity. By now you get the picture. Studies continue to find links between gut bacteria and a variety of mood and mental disorders. Eating a wide variety of plenty of produce is the best way to create a healthy diversity of gut bacteria.
Regular bowel movements from increased fiber of a high-vegetable diet improve your mood. It’s no mystery why constipated babies are so fussy. Research shows a higher prevalence of mood disorders in those with chronic constipation. Although myriad factors can cause constipation, often it’s as simple as too little plant fiber. Eating ample amounts of vegetables and fruits promotes regular, healthy bowel movements (unless you have a gut disorder that makes digesting produce difficult). Constipation increases circulating toxins in the body, which can inflame the brain and leads to bad moods.
What does a serving of vegetables look like?
The new recommendation from the American Institute for Cancer Research is to eat at least five servings a day of fruits and vegetables, but ideally you should eat seven to ten. Five of those servings should be vegetables and two to three fruit (to avoid consuming too much sugar). In other words, two-thirds of each meal should be vegetables.
A “serving” is a vague reference. Here are some ideas of what a serving looks like:
- ½ cup of fruit
- 1 medium piece of fruit
- ¼ cup of dried fruit
- 1 cup of leafy vegetables
- ½ cup of cooked or raw vegetables
Most Americans don’t eat near enough vegetables. It takes some practice and discipline to develop a vegetable habit (vegetable for breakfast, anyone?), but once you do you’ll be motivated by how much better you feel.
Pre-prep veggies for quick salads, and make big batches of veggie soups and stews to facilitate the transition.
