THERE’S NO SUCH THING AS “TOO MUCH PROTEIN”
You may have heard that eating lots of protein can cause all sorts of health problems, including kidney stones and gallstones, but this is a moot point for most people. Why? Because there’s no research showing any relationship between eating a lot of protein and developing kidney problems. In fact, a study published in the Journal of Strength and Conditioning Researchtested eating up to 400 grams of protein per day without any negative consequences.
If you have a pre-existing kidney problem, it’s possible that a higher protein diet could be hard on your body. But if you have a kidney problem, you should be talking to your doctor about your diet anyway.
The fad-free truth: If you’re healthy, you are clear to eat protein and not worry about any health problems—because there are none. What’s more, protein is one of the most metabolic macronutrients, meaning that the more protein you eat, the more calories you burn. Just remember the science of dieting: that calories are still calories so the rules of total intake still apply.
