The Paradox of Longevity

While the average lifespan in western societies has increased, so has the number of health problems in people’s later years. The prolongation of life is not a result of better health but improved healthcare and hygiene practices such as vaccines and antibiotics. Poor diet and lifestyle choices are the main reasons for declining health in old age, causing muscle loss, obesity, heart disease, dementia and more.

The Secret to Longevity

Have you ever wondered what the key to longevity is? According to recent studies, the answer lies in the trillions of bacteria living inside and surrounding our bodies. Good gut bacteria produce nutrients, hormones, and other essential substances that keep us healthy and functioning. To boost longevity, we need to nourish the good bacteria and starve the bad. Eating prebiotic-rich foods like yams, mushrooms, and turnips can promote the growth of good bacteria, while cutting down on sugary fruits like grapes and pineapples can reduce the growth of bad bacteria. By taking care of our gut bacteria, we can improve cognitive function, prevent inflammation, and maintain vitality well into old age.

The Impact of Gut Bacteria on Mitochondria

The human body has bacteria that outnumber human cells and are also found inside most of these cells as mitochondria. Mitochondria convert gut bacteria-processed nutrients into energy and decide how fast cells should grow or die, playing a role in aging. Mitochondrial dysfunction can occur through a diet that disrupts energy production with iron in meat and low oxygen levels. This may lead to neurological disorders such as ALS and Huntington’s. However, certain types of prebiotic foods like nuts can improve energy production by activating gut bacteria to produce short-chain fatty acids like butyrate, an easily available source of protein.

Your Gut Wall: The Third Protagonist of Longevity

In the context of longevity, your gut wall is the protective barrier between your gut and the rest of your body. It is made up of a single layer of mucus-producing cells that line your intestines, which are tightly packed together and interspersed with immune cells. The immune cells play a gatekeeping role by filtering out harmful substances and allowing beneficial ones to pass through. Lipopolysaccharides (LPSs) are one of the main villains in our story and they are harmful waste products that can breach your gut wall and cause chronic inflammation, leading to many common ailments associated with aging. Therefore, keeping your gut wall strong and able to ward off invaders is vital for healthy aging.

The Gut Barrier: Your Health Guardian

Our gut wall is not invincible, and its enemies include lectins, alcohol, and NSAIDs. Lectins can break the tight bonds between gut cells, leaving little holes through which harmful invaders like LPSs can sneak through, resulting in a leaky gut. Excessive alcohol and NSAIDs also damage the gut wall, leading to inflammation and diseases of aging. However, we can prevent this damage by avoiding these gut wall busters and taking measures to strengthen our gut wall.
