The Impact of Diet and Nutrition on Anxiety

Chronic anxiety is when your anxiety lasts for days or weeks. Chronic anxiety is problematic since it can eventually result in health issues. No easy or quick solutions, but you can counteract the damaging consequences by eating to increase or decrease particular substances in your body (3).

Psychotherapy and psychopharmacology are the two types of treatments that are most frequently utilized in the treatment of anxiety-related disorders.

Although many clients find these therapies helpful, a sizable proportion of people claim that they are not easily available, pleasant, or capable of reducing anxiety symptoms to a sufficient degree. These factors have sparked interest in the analysis of complementary or alternative therapy modalities.

The use of dietary therapies in the management and rehabilitation of psychological issues is the subject of the developing field of study known as nutritional psychiatry.

Nutritional advice is rarely given to mental patients in clinical practice, despite mounting evidence of its positive effects. This has been traceable to the inadequate knowledge of the impact of diet and nutrition on the mental health of patients (8).

Smoothies with protein can prevent high blood glucose levels and lessen the chance of sugar spikes.

There is a lot of data that suggests people who suffer from anxiety should think about eliminating or drastically reducing their gluten intake to see if their symptoms could improve. Gluten is problematic for people with non-celiac sensitivity in conjunction with celiac disease. Yet, research has shown that there is a strong correlation between gluten and anxiety (2).

Serotonin is believed to enhance cognitive function and lessen anxiety. As serotonin cannot cross the blood-brain barrier, foods, and drugs containing it do not immediately deliver serotonin to the brain, but they can trigger chemical events that raise serotonin levels there.

According to several studies, nutrition and gut bacteria may be important in both preventing and treating anxiety-related symptoms. To establish whether this is feasible, more investigation is required.

2. Pumpkin seeds

According to a study, pumpkin seeds are a great source of the mineral potassium, which aids in controlling electrolyte balance and blood pressure.

Tryptophan, which is abundant in chocolate and is used by the body to make neurotransmitters that elevate mood, like serotonin, in the brain.

Also, a great resource of magnesium is dark chocolate. Tension and anxiety symptoms may be lessened by taking supplements or eating a diet high in magnesium.

Instead of relying solely on food sources for magnesium, people with magnesium insufficiency may think about using high-dose supplements.

Use dark chocolate with at least 70% cacao. Dark chocolate should only be consumed in tiny servings of 1-3 grams (g) because it still includes additional sugars and fats (6).

Spices like turmeric are extensively employed in Southeast Asian and Indian cuisine. Curcumin, the active component in turmeric, will assist people with anxiety by lowering both oxidative stress and inflammation, two factors that frequently rise in people with mood disorders like anxiety and depression.

In other words, larger consumption of these vitamins was associated with reduced depression.

Also, a 2018 study found that college students typically felt quieter, happier, and more productive on days they ate more vegetables and fruit. This research was reported in Frontiers in Psychology.
