Stress & diet - can food help?

Stress is a common problem that we all have to deal with at some point in our lives. There are many factors that bring stress upon the body - external pressures such as work or family responsibilities, and internal influences - what we eat and how our digestive, immune and nervous systems are functioning.

digestive issues

External stressors can influence food choices (for example, comfort eating) and continuing stress can inflict chronic illness on the body, such as diabetes, depression, mental health problems, cardiovascular disease and digestive issues.

How stress affects the body...

Stress triggers a set of biological responses including:

  • The release of stress hormones from your adrenal glands - adrenaline and cortisol
  • An increase in blood sugar
  • Rising blood pressure
  • Rapid heart beat

All these responses, known as ‘fight or flight’, are designed to help you meet physical challenges that threaten your survival when faced with stress (e.g. how your body would respond if you were being chased by lions). The trouble is, in today’s high stress culture, the stress response continually remains on full alert and the body does not have a chance to recover. 

How hormones affectedHow hormones are affected...

The adrenal glands, nestled on the upper, inner surface of each kidney, produce the main stress response hormones adrenaline, noradrenaline and cortisol. Over time, the adrenal glands become overworked and have difficulty producing the right amount of these hormones. Too much stress can have a negative impact on health, increasing the risk of depression, insulin resistance, diabetes, infertility, heart disease and even cancer.

How diet can help

An important part of any stress response includes identifying and reducing the causes of stress. Adrenal function is significantly influenced by blood sugar levels, therefore much of the dietary advice below aims to stabilise levels of sugar in the blood.

ProteinPrioritise protein. When chronically stressed the body has increased demand for protein. Protein requirements are estimated at 0.7-1.8g per kg body weight daily. Choose lean meat, chicken, fish, eggs, beans, lentils, nuts and seeds in each meal. Protein helps to slow the release of sugar into the blood stream.

EnergyNever skip meals. Ensure that you eat regularly, taking healthy snacks as necessary. Small, regular meals will help to maintain energy levels and mood, while decreasing tiredness and irritability.

SugarAvoid highly refined foods such as white bread/pasta/chocolate/biscuits/sweets or anything with added sugars. Hidden sugars are also in many cereals, breads, tinned produce and processed/packaged foods. Replace processed foods with the unrefined foods such as brown bread, rice, oats and rye. Note that excess alcohol can also cause imbalanced blood sugar levels.

CaffeineWatch the caffeine. Stimulants such as tea, coffee and cigarettes may provide a temporary energy boost, but they reduce energy levels and deplete nutrients in the long term. Aim to drink at least 1-1.5 litres of filtered water throughout the day and replace caffeinated drinks with herbal teas.

DiscomfortEmotional eating. Try not to reach for food when you are in a stressed state. Stress diverts blood flow away from your digestive system, which you don’t want when you are trying to digest your food. You may experience bloating, gas and become prone to discomfort.

Key nutrients

Nutrients that specifically support the adrenal glands include:

  • Vitamin C found in most fresh fruit and vegetables. It is stored in the adrenal gland and is required to make cortisol.
  • Magnesium is dramatically depleted in times of stress, and symptoms of deficiency often include fatigue, anxiety, insomnia and predisposition to stress. Include plenty of dark green leafy vegetables, wholegrains, nuts and seeds to supply adequate levels of magnesium.
  • B vitamins can help to support adrenal function, particularly B5 which directly supports adrenal cortex and hormone production. Sources include wholegrains, nuts and seeds.

Other ways to reduce stress

  • Yoga

    Meditation is a great way to calm your mind, plus it’s free and you can do it anywhere, anytime.

  • Yoga joins the body and the breath so not only is it a great form of exercise but it incorporates meditation to slow down and calm the body and mind.

  • Get outside for fresh air and connect with nature.

  • Good quality sleep is of utmost importance for long term health and regeneration. Few people can function properly with less than seven or eight hours of sleep per night.

  • Regular, gentle exercise is very beneficial for relieving stress and decreasing negative emotions such as worry or anxiety. However, people with significantly depleted adrenal hormones, intensive cardiovascular exercise will further deplete adrenal reserves.

  • Regular relaxation needs to be built into daily life. Reading, having a bath, getting a massage or listening to music are great ways to promote relaxation.

  • Counselling or other therapies may be beneficial for those having to cope in the face of severe stressors. 

If you are feeling stressed and anxious, do not disregard it. Seek advice from your GP or health professional.

Stress and nutrition have always been linked – it’s a fact. Someone with a healthy and balanced diet is likely to be far less stressed than someone with a poor diet. Healthy, nutritious food and breathing exercises are the simplest methods for relieving stress. These methods are not only cost effective but readily available – and without any side effects. Foods with high vitamin and mineral levels actively help to reduces stress levels.
