Hydration for gut health

Water is essential to life and many of us don’t drink enough to stay optimally hydrated. You likely already knew that. A lesser known fact is that adequate hydration promotes a healthy environment for the growth of diverse gut microbiome. Because optimal hydration promotes laxation (going to the bathroom), it decreases transit time of waste through the gastrointestinal (GI) tract. The more quickly waste passes through your GI tract, the better. Drinking water keeps things fluid and lubricated.

Furthermore certain beverages, such as green and black tea, and kefir, a fermented yogurt beverage, directly increase the amount of beneficial bacteria in the gut. A study published in the Journal of Nutrition in 2022 studied the effect of different types and sources of drinking water on gut microbiome. Those that drank more water, particularly well water, had more diverse and numerous healthy bacteria levels. A healthy gut promotes wellness in all areas, including your immune, digestive, and endocrine systems, to name a few.

Moderate Exercise Promotes Gut Health

Studies have shown that engaging in physical activity at a moderate level of intensity has a positive effect on metabolism and the microbiome. Intense training (over 70% of VO2max) reduces microbiome diversity but only in the short term. Elite endurance athletes have high levels of short-chain fatty acids (SCFA) in the gut. SCFAs are producers of healthy gut bacteria.

A sedentary lifestyle, however, is associated with, not only the development of chronic disease, but a loss of muscle mass. This loss of muscle mass, according to experiments conducted in experiments studying the effect of weightlessness on the body, occurs in conjunction with a decline in the amount of SCFA produced, and the microbes that are produced from them.

Other ways to increase SCFA in the gut? Lactobacillus is a bacteria that makes short-chain fatty acids in the intestine. To promote optimal lactobacillus levels, eat more veggies, such as leeks, Jerusalem artichokes, asparagus, onions and garlic. Other foods, such as Kefir, sauerkraut, miso, bananas, yogurt and sourdough bread are helpful.
