Have you heard about the alkaline diet? Celebs endorse the pH-based eating plan that includes basic foods, like broccoli, and acidic foods, like lemons, to promote “alkalinity” in the body. But don’t believe the hype about this pH eating. Here’s what you need to know about the alkaline diet.
Food can't change your blood's pH - Healthy adults have a pH of 7.4, which is slightly-alkaline, since 7 is neutral on the pH scale of 1 to 14. But the acid-base balance of your body doesn’t really change unless your kidneys or lungs aren’t working well.
Alkaline foods are redundant - Alkaline diets claim to give your kidneys a vacation, but healthy kidneys serve as your body’s filtration system, getting rid of the compounds we don’t need and holding on to the ones we do, so they’re already regulating our pH.
Don't be fooled by alkaline waters - Drinking too much alkaline water with a pH of 9.5 or higher could cause nausea, vomiting and diarrhea. Plus, it could cause an adverse reaction with certain medications, so ask a doc before you drink it daily. And there hasn’t been a lot of research to back up health benefit claims of alkaline water, so you’re better off with regular water.
It can keep you healthy — but not because of pH - Alkaline diets claim to have anti-inflammatory and anti-cancer benefits, but it’s not the pH of foods that make them nutritious. Eating foods high in magnesium, potassium, and calcium are linked to lower risk of chronic disease and that’s because they’re full of vitamins, antioxidants, fiber, and healthy fats, not because of the pH.
Weight loss isn't a guarantee - But alkaline diets do include a lot of fruit, veggies, beans, nuts, and seeds, while limiting high-fat animal protein and processed foods, so you’re eating healthier following an alkaline diet, even if you’re not shedding pounds.
