Schizophrenia is a chronic mental illness that causes delusions, hallucinations, and rambling speech and behavior. People with the condition often have bad eating habits as well, which worsens the symptoms. Therefore, following a proper nutrition plan is essential. Studies have shown that eating certain foods and avoiding others can ease the existing symptoms. Below are the five worst foods for schizophrenia. These should be avoided or at least had in moderation.

1. Foods containing gluten
Gluten is a kind of protein present in wheat, rye, barley, and other grains that can affect brain function and worsen psychological symptoms like hallucinations and brain fog. It can also obstruct communication between neurotransmitters in the brain. Moreover, gluten is hard to digest. If one has gluten-based foods often, they may get addicted to it, leading to uncontrolled cravings. Therefore, it is one of the worst foods for schizophrenia.

2. High-fat dairy products
Cheese and other high-fat dairy products may cause inflammation in the body, worsening schizophrenia symptoms. This is especially true for those who are lactose intolerant. If one is not sure about this, they must avoid dairy products like whole milk, butter, heavy cream, etc. for a couple of weeks to see if it helps ease the symptoms in any way.

3. Refined sugar and artificial sweeteners
Items that have refined sugar and artificial sweeteners are the worst foods for schizophrenia patients. Since those with the condition are poor eaters, sugary products put them at a higher risk of diabetes and other ailments. It is also harmful to mood, memory, coordination and can even lead to depression. Hence, it is essential to stay away from cakes, candies, sweetened beverages, and other edibles that contain high amounts of sugar.

4. Packaged and processed foods
Most processed foods have a lot of vegetable oil. These oils contain more omega-6 fatty acids, a high intake of which can impact mental health. Moreover, vegetable oils are low in omega-3 fatty acids – healthy fats necessary for brain health. Studies have shown that low levels of omega-3 to omega-6 in the body can increase the risk of depression and other mental conditions.

5. Certain healthy foods
Although nutritious foods are a must for healthy living, those with high amounts of sugar and unhealthy fats can harm one’s mental health. Some items that are safe for others but harmful to schizophrenia patients include granola bars, juices, and salads with toppings.

As schizophrenia is a lifelong illness, patients should follow a healthy nutrition plan and avoid foods that worsen the symptoms. Foods rich in healthy fats, antioxidants, niacin, folic acid, and vitamin B6 and B12 are recommended. But one should consult a doctor before changing their eating habits significantly.
