Diet & Depression

Diet and Depression

Depression diets were first described in the 2nd millennium BCE. Special diets (including donkey’s milk!) were prescribed in ancient Greece and Rome; and nutritionists have since been looking for possible links between diet and depression. With 350 million sufferers globally; the search for effective treatment and prevention of depression is still on. 

Link between diet and depression

Many people with moderate and severe depression are known to consume food of poor nutritional quality. This is often due to the symptoms of depression itself; such as the loss of appetite; lack of interest in day to day activities; and lack of motivation for self-care. Age, living alone, irregular and hectic work schedules, socio-economic status, cultural and religious taboos may further affect the quality of the diet.

The food we eat is broken down to its simplest forms in the intestines. The nutrients are then used to provide energy for the body and brain; and to synthesize essential compounds. Among them are the hormones and neurotransmitters which act as messengers in the brain. A lack of supply in the diet will therefore certainly affect production of these chemicals.

Bacteria present in our gut help in the breakdown, absorption and even in the synthesis of some of these essential compounds. The type of food we eat, in turn, affects the type of microbes in the gut Thus, there seems to be an important link between what we eat; the microbes in our gut, and all aspects of our health, including mental health.

What are the essential elements of the depression diet?

A diet including whole grains, leafy and colourful vegetables, fruits, nuts and legumes, high quality protein in the form of seafood, chicken and lean meats has been found to be positively correlated to mental health.

• Whole grains contain complex carbohydrates, which are linked to the mood boosting neurotransmitter serotonin. Complex carbohydrates break down slowly in the body, lead to steady levels of glucose in the blood and thus avoid mood fluctuations.
• Proteins of high quality as in egg whites, chicken, fish, milk products, soy products, beans and legumes are the source of the amino acid tryptophan, which is the precursor of serotonin. Trace minerals - selenium, chromium, and zinc, present in beans, legumes, lean meats, dairy products and whole grains are also linked to the brain and mental health.
• Anti-oxidants combat the free radicals which cause cell damage in the brain. Rich sources of anti-oxidants are coloured vegetables such as pumpkin, carrots, spinach(containing beta carotene), citrus fruits, tomato, potato, guava (containing Vit C); nuts, seeds and vegetable oils (having Vit E)
• Omega 3 fatty acids play an important role in mental health and may be used as a supplement in depression. Mammals do not synthesize omega 3 fatty acids and depend on dietary sources which include fatty fish, flaxseeds, and nuts (especially walnuts).

Vitamin D and Depression

Low Vitamin D levels are often seen in depression, but no definite causal association has yet been found. Depression itself may cause low Vitamin D levels, as people with depression are less likely to go outdoors. It would be sensible to correct Vitamin D levels and include fish oils, fish and dairy products in the diet, but use supplements with caution.

In conclusion

Depression cannot be prevented or cured by a special diet. However, a sensible diet including whole grains, proteins, fresh fruits and vegetables will keep you looking and feeling good. Limiting refined starches (the so-called “beige diet” pasta, pizza, bread, baked goods), caffeine, and alcohol also has a beneficial effect on mood. Do not go for any extreme or ‘fad’ diet. It will only add further to your stress and anxiety. A recent study of depression patients shows that diet does not prevent, cure or relieve depression, but diet may have a significant role in recovery and prevention of depression

Diet and dietary supplements are never a substitute for a therapist.

Did you know? Many celebrities and historical figures have suffered from depression. Writer JK Rowling, musicians and singers Lady Gaga, Bruce Springstein, Sheryl Crow, actors Robin Williams, Jim Carey, Gwyneth Paltrow, astronaut Edwin ‘Buzz’ Aldrin suffered from depression. Abraham Lincoln, also a sufferer, once said “If what I feel were equally distributed to the whole human family, there would not be one cheerful face on earth.”

ADHD Diet - practical family meals

Practical ADHD diet for the family

ADHD Diet

A high-protein, low-sugar ADHD diet can help improve ADHD symptoms in children. Parents of children with ADHD are overwhelmed with dietary advice that is often time-consuming and disruptive to the household. However, this need not be so. Research shows it is feasible to incorporate an ADHD diet as part of an ongoing ADHD treatment program. Medication with behaviour modification is the backbone of ADHD treatment. A practical diet can be incorporated into the family routine to supplement ADHD treatment.

High Protein

Foods rich in protein - poultry, fish, eggs, beans, nuts, soy, mutton and low-fat dairy products (milk, paneer, cheese) - may have beneficial effects on ADHD symptoms.

Protein-rich foods are used by the brain to make neurotransmitters, the chemicals released by brain cells to communicate with each other. Protein can prevent surges in blood sugar, which increase hyperactivity. Giving your child protein for breakfast will help his body produce brain-awakening neurotransmitters. Combining protein with complex carbohydrates that are high in fibre and low in sugar will help your child manage ADHD symptoms better during the day.

Low Sugar

Eating simple processed carbohydrates, like white bread and jam, is almost the same as feeding your child sugar! Sugar surges are shown to increase inattention in children with ADHD. The body digests these processed carbohydrates into glucose (sugar) so quickly that the effect is virtually the same as eating sugar from a spoon.

For children with ADHD symptoms serve breakfasts and lunches high in protein, complex carbohydrates, and fibre — like cereals, dalia, upma with vegetables and nuts, and a glass of milk. Peanut butter on a slice of whole grain bread would also be good. The sugars from these carbohydrates are digested more slowly, because protein, fibre, and fat eaten together result in a more gradual and sustained blood sugar release. The result? A child can concentrate and learn better at school.

Supplements

Additive-free and oligoantigenic or elimination diets are time-consuming, disruptive to the household, and impractical. They have no proven role in ADHD treatment. Iron and zinc are best supplemented in children with known deficiencies. Omega-3 fatty acids supplements may be tried in some children with ADHD.

Greater attention to a healthy diet while omitting food that predisposes to ADHD symptoms, is perhaps the most effective and practical ADHD diet.

Diet and mental health

Mental health and diet quality are closely linked. The food choices you made as a teenager affect the development of conduct and emotional problems that continue into adulthood. Lifestyle diseases such as heart disease, diabetes and obesity are attributed to changes in diet and exercise habits. Recently there is increasing evidence that diet and exercise also have a major influence on mental health. Dieting peaks after the festival season. This post will help you avoid the 'isms' and fads and point you in the direction indicated by current research.

A good quality diet predicts better mental health

Evaluating the quality of the complete diet provides a better and more consistent picture of nutrition status than focusing on individual nutrients like magnesium or food groups like various fatty acids (omega, polyunsaturated). A traditional diet of vegetables, fruit, meat, fish, and whole grains is associated with lower risk for depression and for anxiety disorders as compared to a "western" diet of processed or fried foods, refined grains, sugary products, and beer (Jacka 2010).

Switching to a high quality diet improves mental health

Switching to a healthy diet improves mental health. Unhealthy diets are associated with lower scores on mental health tests. The best part is that improvements in diet quality are mirrored by improvements in mental health (Jacka 2011). Also the reverse, when diet quality deteriorates psychological functioning is adversely affected.

What constitutes a high quality diet?

The quality of diet is assessed using food frequency questionnaires. Points are allotted for each type and frequency of food consumed. For example one point is allotted for each of at least two fruit servings per day, at least four vegetable servings per day; using reduced fat or skimmed milk, using soy milk, consuming at least 500mL of milk per day; using high fibre, wholemeal, rye or multigrain breads; having at least four slices of bread per day; using polyunsaturated or monounsaturated spreads or no fat spread; having one or two eggs per week, using cottage cheese, using low fat cheese. Out of a maximum possible score of 74, the average is about 33.0 (+9.0).You can get some idea of your diet quality score from this chart (Collins 2008).

Preventive psychiatry

Improving diet quality improves mental health outcomes. Especially for adolescents this is an important preventive intervention. Three quarters of all long term psychiatric illness manifest during adolescence and early adulthood (Kessler 2005) . These illness are among the most disabling. They occur with a high enough frequency to contribute a major portion of life years lost due to disability. Mental health illnesses cause long-term problems at work and at home. They usually persist over the lifetime and require medication and support at various stages. Adopting a high quality diet is an important primary preventive intervention for improved mental health - easy to implement and proven to be effective.
