5 Foods to Avoid if You Have Bipolar Disorder
Why Diet Is Important When You Have Bipolar Disorder
This is in part because the medications used to treat bipolar disorder can make it difficult for people to feel full and satisfied after eating, and they may eat more as a result, says Melvin McInnis, MD, who is the Thomas B. and Nancy Upjohn Woodworth Professor of Bipolar Disorder and Depression at the University of Michigan in Ann Arbor.
“Choosing foods such as whole grains, produce, and fish can mean that when people with bipolar disorder eat extra helpings, they are eating healthier foods,” Dr. McInnis says.
If you have bipolar disorder, filling your plate with these nutritious foods can help you maintain or achieve a healthy weight, while delivering additional mood and overall health benefits:
Foods to Eat More of When You Have Bipolar Disorder
1. Whole Grains
Whole grains are thought to help increase the production of serotonin, a brain chemical that helps regulate mood and behavior, says April Hackert, RDN, a psychiatric culinary medicine dietitian who specializes in nutrition therapy for people with mental health conditions, based in Iron Mountain, Michigan.
A good place to start is with oats, whether in oatmeal, granola, muffins, or pancakes. “They can be easier on the stomach for people who aren’t used to the fiber of whole grains in their diet,” says Hackert.
2. Mangoes
It’s hard to beat the sweetness — and the nutritional profile — of a mango, making it an excellent food for people with bipolar disorder. According to Hackert, mangoes are especially rich in folate, which may help stabilize mood.
- Fiber, which, as already noted, has many health benefits
- Potassium, which Hackert says may help with side effects from bipolar 1 medications
3. Citrus Fruits
4. Fish and Seafood
Many types of seafood — including salmon, tuna, cod, sardines, herring, and Atlantic mackerel — are loaded with omega-3 fatty acids, including eicosapentaenoic acid, and docosahexaenoic acid. These nutrients may help with brain signaling and also decrease oxidative stress, a type of damage from unstable molecules called reactive oxygen species that can harm the brain, says Hackert.
5. Nuts and Seeds
6. Root Vegetables
- Vitamin C
- Potassium
- Fiber
- Niacin (aka vitamin B3)
7. Avocados
Avocado can be easily sliced and added to salads or sandwiches made with whole-grain bread. On the run? Consider snacking on guacamole in single-serving packages, which can be found in the supermarket’s refrigerated section, paired with a single-serving package of whole-grain crackers, says Hackert.
