Seasonal mood changes are common in autumn

As autumn arrives, many people experience a typical slump: a sour mood, decreased energy, and disturbed sleep. These changes are often linked to reduced natural light, but diet also plays a significant role in influencing mood and energy levels.

Diet impacts mental health and hormones

What we eat directly affects the balance of our intestinal microbiota, our hormones, and our neurotransmitters, according to dietitian Julie Boët. This connection highlights how food choices can influence both physical and mental well-being.

Ultra-processed foods worsen mood

Certain foods can exacerbate fatigue, low morale, and inflammation, creating a vicious cycle between the body and the brain. Ultra-processed foods, in particular, are identified as silent enemies of mental health. Research, including a 2023 study in JAMA Network Open, shows a clear link between regular consumption of these foods and an increased risk of depression.

Ultra-processed foods disrupt gut health

Rich in added sugars, hydrogenated fats, and additives but poor in fiber and micronutrients, ultra-processed foods disrupt the intestinal flora and increase inflammation. This imbalance can affect the gut-brain axis, which is the communication network between the intestine and the brain via the vagus nerve.

Gut health affects brain function

An unbalanced intestinal flora can alter the production of serotonin, a neurotransmitter linked to mood regulation, and worsen mood disorders. Dietitian Julie Boët emphasizes the importance of a healthy diet to support both gut and brain health during the challenging autumn months.
