Dietary Approaches to Tackle Depression: A Nutritional Psychiatry Guide

Introduction:

In the field of nutritional psychiatry, there is an innate connection as established by medical and nutrition research that links the dietary elements or daily food that improve mood, health, and their ability to fight mental health disorders and stress. If this seems surprising, then one needs to know the terminology commonly used in the nutrition field called the "gut-brain connection" or the direct impact of food on the central nervous system and in fighting depression. The simplest logic offered by current nutrition experts across the globe is that what is consumed- vitamins, minerals, antioxidants, or trace minerals- will all directly nourish and impact brain health. Several dietary elements consumed every day can have a positive influence or impact on the brain in short, they can be termed mood-boosting foods. One of the classic examples in which diet can play a major role in shaping life is the prenatal supplementation with folate in a pregnant woman and the nourishment of the fetus through the intake of nutritious foods in pregnancy. This is a classic way that demonstrates how both maternal and child health are boosted only through diet.

What Are the Food Groups That Help to Fight Depression?

Take a look into the important food groups that have been touted by nutrition experts in general to fight off depression and prevent stress, by aiding in food satisfaction and also in simultaneously boosting immunity in a positive mentally impactful way :

1) Purple and Blue-Colored Fruits and Vegetables: There is more to these two colors than meets the eye. The presence of anthocyanin pigments or potential antioxidant compounds is what makes these colors special in boosting systemic immunity. Nutritional psychiatry indicates more than 88 percent of individuals globally cannot meet the appropriate consumption of these positively neurocognitive mood-boosting foods. Not only cognitive dysfunction but anthocyanin-comprising foods are shown to be great mood boosters and can prevent anxiety and stress. The following are some classic examples of purple and blue fruits and vegetables:

• Beets or beet greens.

• Purple radish.

• Blueberries.

• Blackberries.

• Purple grapes.

• Eggplant.

• Purple cabbage.

• Purple carrots.

• Purple potatoes.

• Purple passion fruit.

• Plums.

• Prune fruits.

• Black currant fruits.

• Elderberries.

• Figs.

2) Seafood: As most fatty fish like salmon and sardines are rich in essential fats such as PUFAs (polyunsaturated fatty acids.), primarily omega-3 fatty acids that are high in content of essential compounds like eicosapentaenoic (EPA) and docosahexaenoic (DHA) - these have been deemed by nutritional psychiatry research to be a great proteinaceous source that can boost brain health and skive off feelings of depression. Fish in general are highly saturated in both DHA and EPA which are attributed to an abundant cardioprotective or heart-healthy supply of Omega 3 fatty acids.

3) Eggs: The presence of neurocognitive boosting choline element in eggs, sulfated glycopeptide compounds present in the egg yolk that boost white blood cell production, and their proteinaceous nature gives a natural boost to immunity. Eggs can be all-rounder foods that can be essential in sustaining neurocognitive health.

4) Nuts: According to nutritional psychiatry research on women, consuming nuts regularly can prevent feelings of depression and promote anti-aging effects in women over the long term. Researchers who extensively focused on nut consumption over the years in both men and women, on the other hand, noted that several cognitive parameters were improved over the years in individuals who consumed at least five servings of heart-healthy nuts every week. Most nuts, be it almonds, cashews, macadamias, brazil nuts, pistachios, water chestnuts, walnuts, etc, are a source of heart-healthy polyunsaturated fatty acids (PUFAs) and several phytonutrient compounds that can help individuals fight off stress and depression. Consuming nuts for snacks, in limited servings (a handful usually every couple of hours) can ensure freedom from binge cravings or junk food cravings as well.

Which Diets Can Fight Depression?

There are several common diets that are recommended in nutritional psychiatry to boost neurocognitive health and prevent feelings of mental stress and depression. These diet often include antioxidant-rich foods that fight cellular damage and improve the neurovascular permeability of nutrients,thereby promoting mental health.

1. Rainbow Diet: Consuming fruits, vegetables, and plant proteins that are rich in rainbow colors, basically the different colored fresh or frozen fruits and vegetables - can provide the needed macronutrients, and heart-healthy fiber and also keep satisfaction through the course of a day preventing junk cravings. Nutritional research indicates that the more amounts of fruits and vegetables that are included in a diet, especially those emphasizing vegan or vegetarian diet forms rich in these antioxidants and vitamins - it can be a long-term investment or sustenance of good health.

2. Mediterranean Diet: This diet form is centered on reducing refined sugars, refined grains, and saturated fats. The rationale is to consume whole foods that boost heart health. The Mediterranean diet recommends the consumption of monounsaturated fats (MUFAs), like olive oil commonly alongside plant proteins, fresh vegetables, fruits, whole grains, nuts, fatty fish, etc. Mediterranean diet hence automatically qualifies according to nutritional psychiatry in preventing age-related cognitive decline and in boosting positive mood.

3. The Ketogenic Diet (Keto): Though considered only primarily to be a low-carbohydrate diet with high protein intake meant for weight management, this diet form advocates consuming moderate protein with low-carbohydrate satiating foods. Preliminary medical research and animal studies demonstrate this diet can have a positive effect in preventing mental stress and depression.

4. The Dash (Dietary Approach to Stop Hypertension) Diet: This is a low-fat and low-sodium diet, that focuses on consuming more polyunsaturated fats with lean proteins poultry, whole-grain or fortified cereals, fruits, vegetables, and nuts that are low on calories. These are popular diet forms that are deemed to give a positive boost to neurocognitive health and play a promising role in fighting depression.

Conclusion:

The above enlisted common foods and popular diet forms are only some examples of tested foods through the nutritional psychiatry field that can enhance brain health and prevent cognitive age-related decline responsible for mental stress, feelings of isolation, depression, suicidal tendencies, etc. Understanding the diet or the gut-brain connection can also ensure the boosting of mental health and reducing the overall risk of being prone to depression.
