Food and Mood: How Your Diet Affects Mental Well-being


It has often been said that “You are what you eat”, but have you ever stopped to consider just how deeply your diet can impact your mood and overall mental well-being? The food we consume does not only define our physical health but also plays a significant role in determining our emotional and psychological health.

The Link between Food and Mood

Scientific research has established a clear connection between the food we intake and our mood. The kind of food we eat can influence brain function, behaviour, and emotions. The brain, like every other organ in the body, requires a mix of nutrients to function correctly. So, what we consume can directly affect the structure and function of our brain and, ultimately, our mood.

For example, carbohydrates increase serotonin, a brain neurotransmitter that brings about a soothing effect. However, it’s not just about eating carbs; the type of carbohydrates you eat can make a crucial difference. Simple carbs found in sugary foods and drinks might provide instant gratification but lead to a crash in mood and energy. Complex carbs such as whole grains, fruits, and vegetables are healthier choices.

Nutrients that Boost Mood

There are specific nutrients that are particularly beneficial for mental well-being:

  • Omega-3 Fatty Acids: Omega-3s have been linked with decreased rates of depression and schizophrenia among their many benefits. Foods rich in these beneficial fats include flaxseed oil, walnuts, chia seeds, and oily fish like salmon and mackerel.
  • Vitamin D: Vitamin D increases the levels of serotonin in the brain and has been found to improve mood and reduce symptoms of depression. Although our bodies can produce Vitamin D naturally when exposed to sunlight, it can also be found in foods such as eggs, fish, and fortified dairy products.
  • B Vitamins: B vitamins, particularly B-6, B-12, and folic acid, are crucial for brain health. Deficiencies in these vitamins have been linked to depression. To ensure you’re getting enough B vitamins, include plenty of whole grains, meat, eggs, legumes, leafy greens, and dairy products in your diet.

Mindful Eating for Mental Well-being

Mindful eating is another critical aspect of the connection between food and mood. It involves paying full attention to the experience of eating and drinking, both inside and outside the body. Paying attention to the colours, smells, textures, flavours, temperatures, and even the sounds of our food can be a powerful driver of delight and long-term healthy eating habits.

Mindful eating helps us learn to hear what our body is telling us about hunger and satisfaction. It can foster a healthier relationship with food and with our body. It can also help us make food choices that improve our mood and health.


As the saying goes, “Good food is good mood”. By understanding the impact of food on our mood and mental well-being, we can make better dietary choices. A balanced diet rich in complex carbohydrates, healthy fats, and essential vitamins can significantly boost our mood and overall mental health.

Mindful eating practices also play a crucial role in improving our relationship with food and enhancing our mental well-being. After all, when it comes to food and mood, it’s not just what we eat but also how we eat it.
