You buy fresh, crunchy greens, hoping to get a maximum of vitamins and lightness. However, instead of the expected comfort, within an hour you feel heaviness, cramps and severe bloating. A familiar situation? For millions of people, trying to switch to a "healthy diet" turns into a real test due to the unpreparedness of their digestive tract for large amounts of fiber. But science does not stand still.

After the festive feasts are over, most of us face unpleasant consequences: a feeling of heaviness, flatulence (bloating), bowel disorders and the appearance of a few extra pounds. The traditional reaction to this condition is to try to abruptly go on a strict diet, organize a "detox" or start blindly counting calories.

The change of seasons is not only a change in the weather outside the window, but also a profound transformation within our bodies. Our gastrointestinal tract and the trillions of microorganisms that inhabit it (the microbiome) are evolutionarily adapted to seasonal changes in diet.
