Have you ever noticed that what you put into your stomach changes the way you feel? And not just physically, but mentally? It isn’t a coincidence, it’s science. 

When restrictive eating is a factor in someone’s life, little food, or not enough nutritionally valuable food, can seriously upset the connection between the gut and the brain. This is one of the reasons why during recovery many people experience both physical and mental healing. 

A closer look at that gut-brain connection 

Malnutrition and dietary restrictions can significantly disrupt the delicate balance of gut bacteria, which are crucial for proper digestion and overall health. When we talk about malnutrition, it means the body isn’t getting enough of the nutrients it needs, or it’s getting the wrong kinds of nutrients. This can happen if someone doesn’t eat enough food, eats too much of one type of food or lacks diversity in their diet.

Our gut is full of millions of bacteria that play an essential role in breaking down food, absorbing nutrients and protecting the digestive tract. These bacteria thrive on fiber and variety in a healthy diet. When malnutrition happens as a result of an eating disorder, it can starve these beneficial bacteria. A restricted or imbalanced diet can also lead to an overgrowth of harmful bacteria. This imbalance, often called dysbiosis, can compromise digestion, leading to problems like bloating, diarrhea or constipation.

The gut is a remarkable system not just for digestion but also for its connection to the brain, known as the gut-brain axis. This connection becomes evident when we consider how mood, cravings and anxiety are influenced by our gut health. Our gut bacteria produce and regulate various neurotransmitters such as serotonin, which is crucial for regulating mood. Imbalanced gut flora can lead to a decrease in these hormones, impacting mood and potentially contributing to feelings of anxiety or depression.

Moreover, changes in gut bacteria can influence cravings. When there is a dominance of certain bacteria, they may send signals to the brain that drive us to eat more sugar or fat, feeding the bacteria, but not necessarily nourishing our bodies. This can lead to unhealthy eating patterns and make it challenging to maintain a balanced diet.

In essence, maintaining a well-nourished and balanced diet is crucial not only for digestion but also for our mental well-being. By feeding our body appropriately, we support the health of our gut bacteria, which in turn supports a healthy gut-brain axis. This reduces the risk of mood disorders, curbs unhealthy cravings and minimizes anxiety, contributing to overall better health and quality of life.

What do we need to do when our gut is damaged?

Healing from an eating disorder is a challenging journey involving both physical and psychological recovery. Various strategies can support this healing process, including the use of probiotics, prebiotics, gentle reintroduction of food variety and nutrition counseling. Each of these elements plays a critical role in restoring health and balance.

Probiotics

These are live beneficial bacteria that help replenish the healthy gut bacteria, or microbiota. For individuals recovering from an eating disorder, their gut microbiome is often imbalanced due to poor nutrition, stress or restrictive eating habits. By introducing probiotics through supplements or fermented foods like yogurt and kefir, it’s possible to rebuild the beneficial bacteria in your gut. This can improve digestion, enhance nutrient absorption and contribute to a more balanced mental state owing to the gut-brain connection.

Prebiotics

Prebiotics are types of dietary fiber that feed the beneficial bacteria in the gut. Sources include foods like bananas, onions, garlic and asparagus. Including prebiotics in the diet supports the growth of healthy gut bacteria. For someone recovering from an eating disorder, prebiotics can aid in normalizing digestive function and promoting a healthier gut environment, which can also positively influence mood and reduce anxiety.

Gentle reintroduction of food variety

As part of recovery from eating disorders, gradually reintroducing a variety of foods can help restore nutritional balance to the body. This process should be done gently and mindfully to prevent overwhelming the body and mind, and is best done under the guidance of a specialist. The aim is to expand food choices, incorporating different food groups to ensure a rich supply of essential nutrients and promote a diverse gut microbiome.

Nutrition counseling

The role of nutrition counseling is crucial in recovery as it provides personalized guidance and support. A registered dietitian or nutritionist specializing in eating disorders can help create a balanced diet plan tailored to the individual’s needs, addressing specific deficiencies and goals for recovery.

Nutrition counseling also educates about the importance of nutrients, healthy eating patterns and developing a positive relationship with food. Importantly, it provides psychological support, helping individuals challenge distorted thoughts around food and body image and gradually rebuild a nourishing and less fearful approach to eating.
