Brain and intestines dance to the same rhythm
A study by the University of California and the École Normale Supérieure has discovered that the gut and brain move in unison, following synchronized wave patterns. The contractions that move food through the intestines and the oscillations that deliver blood to the brain operate on the same physical principles. This finding could help us better understand how the body coordinates such distinct functions and provide new insights into neurological diseases.
Taking care of your body is taking care of that inner harmony.

The secret of L-Theanine
L-theanine, an amino acid found in green tea, protects neurons in the hippocampus from sleep deprivation. In mice, it improved memory, learning, and brain function despite sleep deprivation. It reduced oxidative stress and inflammation and preserved neuronal connections. This effect is attributed to its antioxidant activity and the inhibition of ferroptosis, a type of cell damage.
Although the results are promising, further studies in humans are still needed.
A great ally, but not the definitive solution for weight loss
Kombucha isn't a magic bullet for weight loss. A study published in Frontiers in Nutrition (2024) found that, while it doesn't cause weight loss on its own, it provides key health benefits. It helps reduce the risk of type 2 diabetes and cardiovascular disease, controls inflammation, and improves the oral microbiota, decreasing bacteria associated with cavities and gum problems. All thanks to the polyphenols and organic acids generated during fermentation. In short: the scale might not show it, but your body certainly will.

The true sixth sense
Drinking kombucha isn't just refreshing: it's a way to train your gut microbiota to work in your favor. A new study published in Nature shows that when gut bacteria are in balance, they can activate a signal to the brain in seconds, telling it, "You've had enough." This system, which connects the gut to the brain via the vagus nerve, works best when your microbes are well-fed.

Human cells 1 - bacteria 1
The myth that there are more bacteria than humans was debunked in a 2016 study. In reality, the ratio is practically one to one. It's worthwhile to properly feed these bacteria, so important for our daily lives. With kombucha, a very important part of that is already done.

The anti-inflammatory, antioxidant, and antimicrobial properties of kombucha have been revealed.
A new scientific study has analyzed how kombucha varies depending on the type of tea used: green, white, or black. This is confirmed by a scientific study conducted in Thailand. The fermentation process generates organic acids with detoxifying, anti-inflammatory, and antimicrobial effects. Kombucha made with green tea stands out for its antioxidant and anti-inflammatory properties.

Kombucha can modulate the human microbiota
The first clinical trial of kombucha in humans is now a reality. Published in May 2025 in Brazil, the study analyzes the effects of drinking black tea kombucha for eight weeks in adults with and without obesity. The results show positive changes in the gut microbiota, with an increase in beneficial bacteria and a reduction in those associated with obesity.
The brain is in charge: it can change your gut flora in just 2 hours
A study in mice demonstrates that the brain can alter the gut microbiota in just 2 to 4 hours. By activating certain neurons in the hypothalamus, the composition of bacteria in the gut is rapidly modified. This effect is accompanied by changes in the nerve circuits and cells of the gut.

Get your vagus nerve in shape: your health will thank you for it
A study demonstrates that the gut microbiota communicates with the brain via the vagus nerve. In mice lacking bacteria, the activity of this nerve decreased, but returned to normal after the introduction of microbiota. It also decreased with the use of antibiotics, and recovered with the addition of intestinal fluids rich in bacteria. Metabolites such as short-chain fatty acids were key to this activation. The study confirms the direct relationship between the gut and the brain.

Quitting soft drinks: the best decision
A global study estimates that in 2020, sugary drinks caused 2.2 million new cases of type 2 diabetes and 1.2 million cases of cardiovascular disease. These represent 9.8% and 3.1% of all new cases, respectively. The impact was greater among men, young adults, people with higher levels of education, and those living in urban areas. The findings underscore the urgent need for policies to reduce the consumption of these beverages.
