Diet Change And Depression

Depression and anxiety are incredibly common symptoms that we see in primary care. It is estimated that 75-90% of visits to doctors are related to problems caused or made worse by stress. I was so excited to see a new study published showing a link between diet change and depression symptoms!

We all have to eat. Most people recognize that our diet has a huge impact on our health. Heart attacks, strokes, cancers, obesity and many other illnesses are impacted by what we eat. Doctors spend a lot of time advising people to eat less sugar, less saturated fat, and more fresh fruits and vegetables.

Many people don’t realize what you eat affects your mood, too! I’ve had great success with nutritional supplements in helping people with depression and anxiety feel better. A new research study has shown a very clear association between diet change and depression as well.

Researchers in Australia studied 76 young adults with depression and anxiety symptoms. They were randomly assigned to two groups – one group got no intervention, and one group got instructions to improve their diet via a 13-minute video they could re-watch whenever they wanted to.

They were instructed to increase their intake of

  • vegetables to 5 servings per day
  • fruits to 2-3 servings per day
  • whole grains to 3 servings per day
  • lean protein (lean meat, poultry, eggs, tofu, legumes) to 3 servings per day (Remember, plant sources are healthier than animal)
  • unsweetened dairy to 3 servings per day
  • fish to 3 servings per week
  • nuts and seeds to 3 tablespoons per day
  • olive oil to 2 tablespoons per day

They were also instructed to take 1 teaspoon of turmeric and 1 teaspoon of cinnamon most days. They were to DECREASE their intake of refined carbohydrates, sugar, fatty or processed meats and soft drinks. They were given sample menus and handouts answering common questions as well.

After 3 weeks the average depression questionnaire scores had not changed in the control group, not surprisingly. However, in the diet-change group the scores had returned to normal! And the improvement was maintained when they were rechecked after 3 months.

This study supports what I’ve said for a long time. Depression and anxiety are not just related to stress or genetics. Our nutrition strongly impacts our brains’ ability to manage and cope with stress. A crappy diet predisposes us to depression and anxiety, and we can improve our mood by improving our diet.

If you struggle with stress, depression and/or anxiety, improving your diet is something you can do TODAY. Improving your diet is as effective as medication, and works just as quickly. It also has no side effects! What are you waiting for?!

QUESTION: Do you see a link between how you eat and how you feel?
