What do gut bacteria do? How are they associated with your overall health?
In Super Human, Dave Asprey discusses how you can slow down your biological aging and live longer, and he explains how gut bacteria play a role. He suggests two methods for rebalancing gut bacteria: adding more fiber to your diet and reducing your exposure to antibacterial products and antibiotics.
Learn the details of Asprey’s advice on how to balance gut bacteria.
How to Balance Gut Bacteria
Asprey explains that it’s important to know how to balance gut bacteria because such an imbalance is a cause of mitochondrial inefficiency. Mitochondrial inefficiency leads to poor health and accelerated aging.
Asprey explains that gut bacteria help maintain the integrity of your gut lining—the barrier between your digestive tract and bloodstream. Your gut lining plays a massive part in the health of your immune system because it absorbs necessary nutrients from your bloodstream and prevents toxins from your digestive tract from leaking into your bloodstream. However, when your gut bacteria are out of balance, your gut lining breaks down, fails to absorb nutrients, and leaks toxins into your bloodstream.
According to Asprey, various factors cause gut bacteria to become imbalanced, including eating produce derived from animals that have been fed antibiotics or from crops sprayed with insecticides, using antibiotics or antibacterial soaps, and consuming an insufficient amount of fiber.
Symptoms of Imbalanced Gut Bacteria While Asprey details the causes and effects of imbalanced gut bacteria, he doesn’t include information on how you might determine whether this is an issue you’re dealing with. Physicians provide a list of symptoms to keep an eye out for: —Autoimmune problems, such as thyroid issues, rheumatoid arthritis, or type 1 diabetes —Digestive issues, such as irritable bowel syndrome, constipation, diarrhea, heartburn, or bloating —Excessive sugar cravings —Chronic fatigue or problems sleeping —Skin irritations, such as rashes or allergies —Mood disorders, such as depression or anxiety —Unexplained weight fluctuations |
Let’s explore Asprey’s advice on how to balance gut bacteria.
Method #1: Add More Fiber to Your Diet
The first method for rebalancing your gut bacteria is to add more fiber to your diet. Asprey explains that fiber feeds your healthy bacteria (leading them to multiply) and provides the perfect environment for them to thrive. He suggests that you can maximize your production of healthy gut bacteria by eating lots of fibrous vegetables and consuming 10 to 30 grams of powdered fiber each day.
