If you feel overworked, slammed and out of breath, you are not alone. No less than one quarter of Canadians aged 15 and older reported that most days were quite stressful or extremely stressful1. There are many consequences of stress on health, including heart disease, stroke and high blood pressure, as well as complications related to the immune system and the circulatory system1. A true and merciless societal curse…
The Other Brain or When Stress Gets to Your Guts
The brain and the intestines are intimately connected by a real motorway of neural connections. The researchers showed that in case of stress, there is more intestinal permeability which promotes the passage of lipopolysaccharides in the bloodstream. The effect is twofold, since an imbalance of the mocrobiota, that is to say the intestinal flora, leads to a disproportionate reaction to stress.
Natural Anti-Stress Remedy
In response to acute stress, probiotic supplements reduce the production of cortisol (stress hormone) and alleviate anxiety. Studies suggest that the Bifidobacterium longum bacterial strain has beneficial effects on stress-related behaviours, physiology and cognitive performance in mice2, 3. The probiotics are recognized as «psychobiotics», that is to say as living organisms that, when ingested in sufficient quantities, produce benefits for people with mental health problems and those living in stressful life situations4.
