Chronic stress can have a negative effect on our physical health as well as our mental wellbeing. It can play a role in our susceptibility to illness and disease, but also in day-to-day functional problems such as pain and stiffness.
There are many steps we can take to improve our ability to cope with stress; nutrition is one of them. Find out what and how to eat to better manage stress…
Balancing your blood sugar
To cope well with stress, we need our food to provide us with balanced, sustained energy. Foods that quickly break down into glucose and are quickly absorbed – such as sugary foods and fast-releasing carbohydrates – may give us a burst of energy, but can cause our blood sugar to peak and then dip. This can actually increase our body’s stress response and stress hormone levels, as well as making us feel irritated and out of control.
Here are the three fundamental steps to balancing your blood sugar:
- Eat primarily whole foods: vegetables, animal foods (eggs, fish, unprocessed meat, unsweetened dairy foods), nuts and seeds, beans and lentils, and some fruit. Avoid sugary snacks, refined carbohydrates and other processed foods such as breakfast cereals
- Making sure every meal includes a good serving of protein, healthy fats, and complex carbohydrates. The primary protein foods are the animal foods mentioned above, and nuts and seeds, and beans and lentils. Healthy fats are found in nuts and seeds, oily fish, avocadoes, and coconut. Complex carbs are found in vegetables, whole fruit (i.e. not fruit juices), whole grains, beans and lentils
- Eat regularly. Skipping meals or leaving too long between meals can cause your blood sugar level to drop too low, which can also trigger a stress response
Getting enough food
As well as eating regularly, getting enough food is important when you’re dealing with stress. Going on a weight loss diet – whether it’s low-calorie, low-carb or low-fat – during a stressful time can be particularly bad for your stress levels. Instead, now is the time to focus on balancing your blood sugar as outlined above, by eating regular meals, getting enough protein, healthy fats and non-starchy vegetables and cutting the refined carbohydrates and junk foods. You should find it easier to manage your weight – or lose weight – by eating in this way anyway.
Although regular snacking is not the best thing for everyone, it can be helpful if you’re coping with stress, again by helping to keep your blood sugar on an even keel. Your snacks need to be based on whole foods, and contain some protein and complex carbohydrates.
- Two or three oatcakes with one of the following: a tablespoon of hummus, guacamole, cottage cheese, half an avocado, a hard-boiled egg or a teaspoon or two of nut butter (e.g. almond butter).
- A pot of natural yoghurt (without added sugar) with some berries and/or a tablespoon of pumpkin seeds mixed in.
- A wedge of left-over home-made frittata/omelette.
However, you shouldn’t need to be snacking more than once between meals; constantly ‘grazing’ can have a negative effect on your weight and your digestion!
The mineral magnesium plays a vital role in our psychological health, including our mood and how well we cope with stress. It’s thought that both physical and emotional stress can increase the body’s need for magnesium; and that having a low magnesium to calcium ratio can actually increase the release of stress hormones such as adrenaline.*
The best food sources of magnesium are green leafy vegetables such as kale, chard and spinach; seeds and nuts; and whole grains – especially buckwheat and rye.
B vitamin-rich foods
Like magnesium, B vitamins also play a vital role in our energy as well as our psychological function.
The various B vitamins are found in different foods, but the best all-round sources include eggs, oily fish, organ meats (especially liver), seeds and nuts, and beans and pulses. Luckily these are also foods that are great for our blood sugar balance!
Avoid overdoing stimulants
Many of us turn to stimulants such as tea and coffee when we’re feeling stressed. But stimulants of any kind also trigger the body’s stress response. Try to keep your coffee consumption in particular to a minimum. Tea can have a gentler stimulating effect so can be better tolerated, but keeping it to one cup a day can still be advisable. Try to introduce calming herbal teas such as chamomile and spearmint – especially later in the day.
Note that alcohol can also act as a stimulant as well as a relaxant. It also disrupts your blood sugar balance. Keep alcohol to a rare treat and stick to one drink only.
