Although I was pleased to present a webinar recently to APSCO members on “16 Ways To Improve Your Self Confidence”, one important strategy I didn’t suggest was the important role that eating properly plays in building your self confidence and self esteem. These two essential components of Mental Toughness within Control and Confidence in the MTQ48 4C’s framework can be further developed by selecting the right food.

In this short post I explore how to eat your way to self confidence, courtesy of some insights below from the UK web site Nutritionist Resource. Also read “Why These 5 Quick Tips On Food Are Important For Your Brain”.


The idea that food can affect our mood and behaviour isn’t new and researchers have found some fascinating links between what we eat and mental health. When it comes to self confidence and self-esteem, considering your diet and making any necessary changes can help to reduce anxiety, boost your mood and in turn help you feel better about yourself and more confident.

So, how does food do this? It’s all about getting the right balance of nutrients from foods which can help our mood and the way we feel. For example eating carbohydrate-rich foods make the brain receive more serotonin – a hormone that makes you feel positive, relaxed and confident. Too many foods or drinks that are high in sugar or caffeine however can cause mood fluctuations, which can leave you feeling lethargic, irritable and anxious.

Some research also suggests that low levels of vitamins, minerals and essential fatty acids can affect our mental health; for example, links have been seen between depression and low levels of omega-3 oils.

Mood boosting foods

Ensuring your diet comprises of nutritious foods with vitamins, minerals and good fats is the best way to help you boost your mood and feel more confident in yourself. In addition to this, there are certain types of foods known for their mood-boosting qualities, including:

Carbohydrates – These are broken down into glucose which is essential to supply the brain and muscles with energy. Too little and an irregular intake of carbohydrate foods can leave you feeling tired and lacking concentration. Eating plenty of unrefined carbohydrate foods, for example whole grains, vegetables and fruit can help sustain your energy levels for longer. Carbohydrate-rich foods may also help the brain receive more serotonin. Serotonin is made using tryptophan, a part of protein from the diet. Therefore make sure your diet contains a variety of protein sources, such as meat, fish, eggs, low fat cheeses and pulses which also contains other essential nutrients.

Foods rich in omega-3 fatty acids – In recent years there have been studies that suggest omega-3 fatty acids can help to prevent low moods and depression as they affect the neurotransmitter pathways in the brain. Ensure you are eating at least one portion of oily fish a week (no more than two if you are pregnant or breastfeeding) such as sardines, salmon, mackerel and trout.

Foods rich in vitamin D – This vitamin is thought to increase levels of serotonin in the brain, so aim to include foods in your diet that contain vitamin D such as eggs, oily fish, yoghurt and fortified cereals.

Foods rich in vitamin B – Another key vitamin for energy production, low levels of vitamin B have been noted in those with depression. Foods like spinach, broccoli, meat, dairy and eggs are great sources of B vitamins.

Foods rich in selenium – Studies have shown a link between low selenium levels and poor mood, so try to include foods like lean meat, whole grains, brazil nuts, oats, beans/legumes, seafood, nuts and seeds.

Foods to limit

As well as including all the right mood boosting foods, you may find reducing your intake of certain foods can help with self-esteem too. Take a look below for some foods to limit:

Sugar – If you’re not feeling good about yourself you may instinctively reach for a sugary snack to perk yourself up. This may work in the short-term, however the spikes and falls in blood sugar levels will disrupt your mood and leave you feeling drawn out and lethargic in the long run. Try to replace sugary snacks for a piece of fruit, nuts or seeds instead.

Caffeine – Drinks like coffee and caffeinated soft drinks can cause mild dehydration if too much is consumed and may lead to withdrawal headaches. Similarly to sugar, if too much caffeine is consumed it can disrupt your energy levels and cause mood swings, which over time can affect your confidence. Try to reduce the amount of caffeine you consume and up your intake of caffeine free herbal teas and water.

Alcohol – Drinking alcohol may give your confidence a brief lift, but as too much alcohol can be both a stimulant and depressant you are likely to feel irritable and anxious the following day. Avoid drinking over the recommended guidelines and have at least two alcohol free days a week – your body and mind will thank you for it.
