Relationship between Diet and Mental Health in a Young Adult Appalachian College Population
Multiple studies have found a correlation between a diet high in the association between diet quality and mental health across countries. Mental disorders, particularly depression, account for the highest burden of global . The other aspect of the relationship between diet and mental health is the. Both these inequality factors have also been shown to have a complex relationship with poor nutrition4. Experience of a mental health problem may also be.
DIET AND MENTAL HEALTH
This will likely leave you feeling weak and tired. Cutting out entire food groups. If you reduce the variety of foods in your diet, it can be more difficult to get all the essential nutrients you need. Low levels of zinc, iron, B vitamins, magnesium, vitamin D, and omega-3 fatty acids are associated with worsening mood and decreased energy. Eating too many refined carbohydrates.
High intakes of unhealthy, processed carbohydrates, such as white bread and pastries, cause blood sugars to rise and fall rapidly.
This can lead to low energy and irritability. Beyond mood and general well-being, the role of diet and nutrition on mental health is very complex and has yet to be fully understood. Animal experiments also suggest that foods high in saturated fat and refined sugar are addictive, interacting with the dopamine system in the way that other addictive products do. The very large body of evidence that now exists suggests that diet is important to mental health in the same way as it is to physical health.
We now believe that the opposite is also true and that physical and mental health should be considered two sides of the same coin.

In this sense, the same dietary and physical activity recommendations that are made to prevent and treat common physical diseases are also relevant for mental disorders. Thus, there is no longer a justification for not addressing the whole person when treating mental disorders.
It may well be that a dietitian will soon become part of every multidisciplinary psychiatric team and that, in the future, referrals to dietitians will be common for people with mental disorders. For individuals the recommendations are no different for any other aspect of health: At the same time, processed foods should be assiduously avoided. They contain high levels of unhealthy fats, sugars and refined carbohydrates, as well as other components that are increasingly being shown to have a detrimental impact on gut microbiota, such as artificial sweeteners and emulsifiers.
We would also add here that fibre is key — gut microbiota act to influence health by fermenting fibre and we now believe that our microbiota may be the key to health. Plant foods have high levels of fibre and we should be aiming for 50 grams per day. Vinegars such as balsamic and apple cider also appear to be very beneficial to the gut, as are the fermented foods such as sauerkraut, kimchi, kombucha, tempeh and other such traditional foods. Interestingly, many alternative health practitioners have been advocating for these foods since the s, but now the science is starting to catch up with the recommendations!
There also seems to be a role for nutritional supplementation in some people under certain circumstances. For example, omega 3 fatty acids, found in fish, appear to be helpful for people suffering from quite serious depression.
Similarly, there are studies starting to emerge to suggest that zinc or vitamin B supplementation may be helpful for some. There is also an amino acid called N-Acetyl Cysteine NAC that has been shown to be particularly helpful for people with depression, schizophrenia and bipolar disorders. There is also a lot of animal research that points to zinc as an important nutrient in mental health. Zinc supplementation appears to be helpful for depression in conjunction with other treatments, while dietary zinc intake is also protective for depression in the population.
Zinc is a powerful antioxidant and also seems to exert beneficial effects on the gut. So what we need to do now is understand what supplements are useful for individuals under what circumstances.

It may be, for example, that gut dysbiosis means that nutrients in the diet are not optimally absorbed or utilised, meaning that there is a need for supplementation even when dietary intake is adequate.
These are the sorts of studies we need to now undertake.
We need to recognise that addressing diet quality will have benefits for the many physical disorders that commonly accompany depression, such as heart disease, diabetes and obesity, and invoke the precautionary principle. When we have many lines of circumstantial evidence, from population studies and animal experiments, that repeatedly tell us that diet influences both the risk for depression and its underlying pathophysiology, it seems prudent to address unhealthy diet in those with depression — even without the evidence from randomised controlled trials.
The critical new understanding that diet is of relevance to mental as well as physical health now gives us the opportunity to think about public health, prevention and treatment strategies that focus on dietary improvement.
Interventions focused on improving diet and exercise, designed to prevent physical illnesses such as heart disease, diabetes and obesity, are also likely to help to prevent and treat depression and other mental disorders.
