1. Physiological responses to stress
When we are stressed, our body goes through a series of physiological reactions known as the "fight or flight response." This response increases the production of stress hormones such as adrenaline and cortisol. These hormones prepare the body for a rapid response by providing energy and modulating various bodily functions.
2. Increased energy and nutrient use
During times of stress, the body uses more energy to support the increased activity of stress hormones. This leads to an increased need for certain nutrients, particularly those involved in energy production, such as B vitamins, magnesium, and vitamin C. These nutrients are depleted more quickly when the body is constantly in a "state of alert."
3. Impaired nutrient absorption
Stress can negatively affect the functioning of the digestive system. Chronic stress can lead to digestive problems such as irritable bowel syndrome, gastrointestinal inflammation and an imbalance of gut flora. These conditions can impair the absorption of nutrients from food, thus contributing to deficiencies.
4. Reduced food intake
Stress can also affect eating behavior. Some people tend to eat less during stressful times or reach for unhealthy foods that contain fewer nutrients. Stress-related overeating of processed foods can also lead to nutrient deficiencies, as these foods are often low in essential vitamins and minerals.
5. Increased loss of nutrients
Another effect of stress is the increased loss of nutrients through excretion. For example, increased cortisol levels can reduce magnesium levels in the body, as this mineral is excreted more in the urine. The same is true for other micronutrients such as zinc and calcium.
Summary
High levels of stress lead to increased demand for nutrients, reduced absorption of these nutrients due to digestive problems, altered eating behavior, and increased loss of nutrients. These factors all contribute to the fact that people who are under chronic stress may be more likely to suffer from nutrient deficiencies. Supplementing with micronutrients may therefore be a useful measure to mitigate the health effects of stress and support overall health.
