Data Coding And Analysis
Data was classified through a mix of a priori and iterative coding strategies. Fields that were decided a priori served to identify both trends and gaps. Iterative coding included the specific measures within FSN and mental health groups. For example, although we had pre-identified a list of common and validated measures of anxiety or depression, or food security, there were many more measures that emerged beyond initial lists. These were grouped into a code if more than one study employed the measure. We used a coding form built in EPPI Reviewer to extract data on eligible reports. Only analytical comparisons and their characteristics were considered for data extraction.
We extracted information on publication year, country and regions, study design, hypothesized direction of association between FSN and mental health and specific categories of measures and indicators, study population characteristics and sample size, and whether the analysis was adjusted or not . For the hypothesized relationship, we coded based on the authors stated aims and methods even for cross-sectional and qualitative studies. The adult population category included any age range over 18, whereas studies with populations limited to older people were coded with mid- to later-life populations only.
Diet And Emotional Well
Diet is such an important component of mental health that it has inspired an entire field of medicine called nutritional psychiatry. Mind-body medicine specialist Eva Selhub, MD has written a superb summary of what nutritional psychiatry is and what it means for you right here on this blog, and its worth reading.
What it boils down to is that what we eat matters for every aspect of our health, but especially our mental health. Several recent research analyses looking at multiple studies support that there is a link between what one eats and our risk of depression, specifically. One analysis concluded:
“A dietary pattern characterized by a high intake of fruit, vegetables, whole grain, fish, olive oil, low-fat dairy and antioxidants and low intakes of animal foods was apparently associated with a decreased risk of depression. A dietary pattern characterized by a high consumption of red and/or processed meat, refined grains, sweets, high-fat dairy products, butter, potatoes and high-fat gravy, and low intakes of fruits and vegetables is associated with an increased risk of depression.”
Depression Screenernational Health And Nutrition Examination Survey
NHANES is a program of studies designed to assess the health and nutritional status of adults and children in the United States, which is conducted in 2-year cycles. The survey is unique in that it combines interviews and physical examinations. The Depression Screener has been administered during a computer-assisted personal interview as part of NHANES since 2005.

How Can Food Help Overcome Mental Anguish
They say we are what we eat but, unfortunately, we cant eat sunshine and smiles. We can, however, eat in a way that reflects the link between nutrition and depression.
The Mediterranean diet, with its fresh fruits and vegetables, fish, seeds, and nuts can reduce symptoms of depression. Meanwhile, a study led by the University College London found that:
following the plant-rich diet was associated with a 33 percent reduced risk of depression
Similarly, research into the DASH diet has also shown positive results in terms of providing nutritional support for depression. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, was designed to help people with high blood pressure but studies are now showing that individuals who adhere to the DASH diet have lower rates of depression compared to those with diets high in saturated fats and red meats and low in fruits and vegetables.
Unfortunately, many of us turn to the wrong foods to heighten our moods. Traditional comfort foods are high in salt, sugar, and fat and, while they give a temporary boost, the subsequent crash is harsh.
While some anxiety nutrition solutions require an increase in plant-based foods, Omega-3s, and antioxidants, others demand that we give up highly processed foods and those with high sugar content.
Foods To Help Depression And Anxiety
When there is an onset of anxiety that can lead to depression, this is an ongoing disease that continues to be researched. However, physicians have learned that what we eat helps to keep our neural system and the body, working well and healthy.
Our food contains nutrients like vitamins, compounds, minerals, and more that directly affect how we feel and function.
Here are just a few goods that go along way in helping to control our anxiety and lessen depressive emotions:
- Fibre foods filled with fibre helps our body to absorb excess glucose or food sugars. Fresh fruits like apples, pears, oranges, and berries are rich in fibre. Other fibre-filled foods include vegetables like carrots, brussels sprouts, peas, corn, potatoes, etc. Grains, oatmeal, nuts, beans, are also fibre-enriched foods.
- Antioxidants antioxidant foods fight inflammation in all parts of the human body. Anti-inflammatory foods include leafy green veggies, berries, salmon, dark chocolate, and certain spices like turmeric, cinnamon, ginger, curry, paprika, and more.
- Folate Folate is vitamin B which helps to construct our DNA cells plus it produces red blood cells. Foods high in folate include green and leafy vegetables, legumes, eggs, citrus fruits, and lentils are filled with folate. Leafy veggies contain anti-inflammatory compounds that help lessen inflammation of the brain, which is causes depression. They help to keep our immune system strong, which aids in keeping us physically and mentally healthy.

What Can I Eat To Help Fight Depression And Anxiety
Have you ever been so stressed out that your stomach hurt? Perhaps you were so worried or anxious that you vomited or had diarrhea. Even that nervous butterfly feeling you sometimes get is a sign that the balance of microbes in your gut is off balance.
You have a staggering 100 trillion microorganisms, or bacteria, living in your gastrointestinal tract. Although we tend to associate bacteria with germs, there are good and bad bacteria. Good bacteria kill disease-producing cells, build vitamins and hormones, and help break down food.
Researchers have long known that stress, anxiety, and depression reduce the presence of good bacteria in your gut, leading to gastrointestinal distress. But does it work the other way around?
Which Foods Are Important For Brain Health And Cognitive Function
A Mediterranean style diet is not only good for physical health, but also for mental health and cognitive function. Aim for a diet high in plant based foods such as whole grains, fruits and vegetables. Include heart healthy fats coming from fish, nuts, seeds and olive oil and legumes, lean meats, poultry and seafood as the foundation of your diet.
Research has shown that diets limited in the above healthy foods and that contain a high intake of saturated fat, trans fat or an excessive processed sugar intake can contribute to oxidative stress and inflammation in the body which changes vascular function in the body. This can increase the risk mental health conditions such as depression and anxiety as well as cognitive decline.
Note that you dont need to eliminate any of these foods, the key is to be mindful of your choices. There is always room for fun and flexibility in our diet and for foods such as desserts and savoury snack foods chosen for taste and social enjoyment. The key is #balancednotclean.

What Is The Overall Connection Of Nutrition And Mental Health
What you eat directly influences mental health. Conversely, your mental health can influence what you eat.
This food mood connection can be positive or negative. Your food choices can uplift mood, energy and overall mental health. Unfortunately what and how we eat can also negatively lower mood, productivity and your ability to concentrate. It can also increase the risk of anxiety and depression.
Food is the building blocks of your brain. In many ways you are what you eat. Healthy food is required for the physical structure of the brain tissue and the neurotransmitters that transfer information between the brain and other parts of your body. This process simply cant happen seamlessly without healthy food.

Anxiety And Depression: Can Diet Help
In November 1944, Dr. Ancel Keys and Dr. Josef Brozek, faculty at the University of Minnesota, conducted a study on the effects of starvation, known as the Minnesota Starvation Study . Through this study, it was observed that a lack of nutrients can lead to intense physical and psychological changes such as decreased strength and stamina, as well as increased fatigue, irritability, depression, and overall disinterest . This was the first study of its kind to demonstrate the connection between nutrition and mental health.
Seventy-five years later, it is estimated that 20% of the general population has experienced a mental health disorder within the last 12 months, and 29% of the population will experience anxiety and/or depression in their lifetime . The common symptoms of anxiety and depression are similar to the psychological changes described by the subjects in the Minnesota Starvation Study . Depression is often characterized by: fatigue, difficulty concentrating, restlessness, irritability, trouble sleeping, loss in appetite, and feelings of hopelessness . Likewise, anxiety is characterized by: irritability, feelings of being out of control, fatigue, weakness, excessive worrying, and trouble sleeping .

Nutrition For Depression And Anxiety
Depression and anxiety are the two most common mental health issues in the U.S. Over the past decade or so, more and more research is linking these common issues with lifestyle habits, meaning that what we eat and how much we move, sleep, play and stress out can affect our mental health. This doesnt mean that medications and talk therapy arent helpful, it just means that maybe they shouldnt be the only focus.
The foods you choose can have a powerful impact on your mood and overall brain health. Poor diet is a major contributing factor to the epidemic of depression and anxiety. There are many studies showing the direct connection between diet and depression. Unfortunately, there are fewer studies that directly link diet and anxiety but there is research that connects inflammation, oxidative stress and alterations to the microbiome with anxiety, all of which are highly influenced by diet.
Anxiety And Depression Optional Modulebehavioral Risk Factor Surveillance System
The BRFSS is an annual state-based telephone survey of the U.S. civilian, non-institutionalized adult population. The core questionnaire contains questions asked of all respondents, while states may choose to also include optional modules addressing various topics. The optional Anxiety and Depression Module assesses the prevalence of anxiety and depressive disorders in the general population at the state level. This module is composed of the Patient Health Questionnaire which has been validated against the nine diagnostic criteria for a depressive disorder in the Diagnostic and Statistical Manual for Mental Disorders .

Nutritional Strategies To Ease Anxiety
- By Uma Naidoo, MD, Contributor
According to the National Institute of Mental Health, anxiety disorders are the most common mental illness in the United States. Thats 40 million adults18% of the populationwho struggle with anxiety. Anxiety and depression often go hand in hand, with about half of those with depression also experiencing anxiety.
Specific therapies and medications can help relieve the burden of anxiety, yet only about a third of people suffering from this condition seek treatment. In my practice, part of what I discuss when explaining treatment options is the important role of diet in helping to manage anxiety.
In addition to healthy guidelines such as eating a balanced diet, drinking enough water to stay hydrated, and limiting or avoiding alcohol and caffeine, there are many other dietary considerations that can help relieve anxiety. For example, complex carbohydrates are metabolized more slowly and therefore help maintain a more even blood sugar level, which creates a calmer feeling.
A diet rich in whole grains, vegetables, and fruits is a healthier option than eating a lot of simple carbohydrates found in processed foods. When you eat is also important. Dont skip meals. Doing so may result in drops in blood sugar that cause you to feel jittery, which may worsen underlying anxiety.
Include Oily Fish In Your Diet
Some researchers think that omega-3 oils, found in oily fish, may also help with depression. Aim for at least two portions of oily fish per week. Oily fish include salmon, mackerel, herring, sardines, pilchards and trout.
You can find out more about including omega-3 in your diet, including if you do not eat fish, in our Omega-3 Food Fact Sheet.

Increase Intake Of Chromium
Chromium is vital for keeping your blood sugar level stable because it is required for the functioning of insulin, which clears glucose from the blood. Good food sources of chromium include broccoli, turkey, liver, whole grains, seafood and green beans. Chromium can also be taken in a supplement form called chromium picolinate, although this should be done under the supervision of a doctor, particularly if diabetes medications are being taken .
The Science Behind Food And Mood
The connection between diet and emotions stems from the close relationship between your brain and your gastrointestinal tract, often called the second brain.
Heres how it works: Your GI tract is home to billions of bacteria that influence the production of neurotransmitters, chemical substances that constantly carry messages from the gut to the brain.
Eating healthy food promotes the growth of good bacteria, which in turn positively affects neurotransmitter production. A steady diet of junk food, on the other hand, can cause inflammation that hampers production. When neurotransmitter production is in good shape, your brain receives these positive messages loud and clear, and your emotions reflect it. But when production goes awry, so might your mood.
Sugar, in particular, is considered a major culprit of inflammation, plus it feeds bad bacteria in the GI tract. Ironically, it can also cause a temporary spike in feel good neurotransmitters, like dopamine. That isn’t good for you either, says Rachel Brown, co-founder of The Wellness Project, a consultancy that works with corporations to promote good health among employees. The result is a fleeting sugar rush that is followed shortly thereafter by a crash “that’s terrible for your mood,” she says.

Depression and anxiety are the most common mental health conditions in the world. Counselling and medications are the cornerstone of managing many mental health problems. But now we are discovering that what we eat can also have an important role.
A nutritious diet is not just good for your body. It is good for your brain and mental health too. A healthy diet is linked with better stress management, concentration and improved mental health.
How food and mood are related is a two-way street. What you eat can affect your mood, but your mood also influences what you choose to eat. Youre more likely to make positive food choices when youre in a good headspace.
When youre feeling stressed or depressed, it can mean turning to comfort food to feel better. However, some of these easy-to-buy foods are highly processed and rich in sugar, salt and fat. Be aware that these foods will not benefit your mental health.
Connection Between Diet And Depression
“Research shows an association between dietary patterns that are rich in fruits and vegetables and lower in processed foods with improved mood and well-being ratings, as well as a lower risk for depression, says Gary D. Foster, Ph.D., WW Chief Scientific Officer.
One recent study published in the journal Nutrients found that people who consumed greater amounts of fruits and vegetables reported greater levels of optimism and self-efficacy.
And a systematic review published in the European Journal of Nutrition looked at 16 studies and suggested that people who ate Western/unhealthy diets such as more fast food, sweets, and sugary soft drinks had an increased risk of developing depression, while those who followed a healthier pattern of eating, including a Mediterranean style diet, seemed to have a protective effect on the development of depression over time.
However, while fruit and vegetable consumption is associated with greater well-being, Foster says theres no real scientific evidence that suggests that fruit and vegetable consumption causes improved mood. Instead, it is an observed association between patterns of eating and mental health, he says.
We just dont know enough at the moment to draw firm conclusions about the link between dietary intake and depression, Foster says. Additionally, he says more research is needed to see whether diets that are high in fat and sugar are linked to changes in mood and depression risk.
