När vi äter mycket fibrer får våra fibernedbrytande bakterier näring – och de ger tillbaka hälsofrämjande ämnen som kortkedjiga fettsyror med antiinflammatoriska och cancerskyddande egenskaper.
Goda tarmbakterier producerar också organiska syror, som mjölksyra, vilket sänker pH-värdet i tjocktarmen. Ju mer växtbaserad kost, desto lägre pH. Äter vi mycket animaliskt protein bildas istället mer ammoniak, vilket höjer pH – och ett högre pH kan öka risken för tjocktarmscancer.
Det tar bara två veckor på växtbaserad kost för att sänka pH-värdet. Byt ut bara två portioner rött kött mot linser, kikärtor eller bönor några gånger i veckan – det förbättrar inte bara pH utan även blodsocker, insulinkänslighet, kolesterol och triglycerider.
When we eat lots of fiber, we feed our fiber-eating bacteria. These kinds of bacteria give us back all sorts of health-promoting substances, including short-chain fatty acids, which have anti-inflammatory and anti-cancer properties.
Good bacteria in our gut also produce organic acids, like lactic acid, which help lower the pH of our colon. Plant-based diets appear to shift the makeup of the bacteria in our gut, resulting in a significantly lower stool pH. The more plant-based, the lower the pH.
When we eat lots of animal protein, we produce more ammonia in our gut, which in turn increases the pH of our stool. A higher pH in our colon may promote the creation of carcinogens from bile acid that put us at higher risk for colon cancer.
How long does it take to lower the pH of our stool on a plant-based diet? As little as two weeks.
Replace just two servings of red meat with lentils, chickpeas, split peas, or beans a few days a week. Not only does that impact our pH, but we can get other health benefits, too. Research shows a significant improvement in fasting blood sugars and insulin levels––along with the improvements in lowering cholesterol and triglycerides––when eating legumes instead of meat.
