The Claim
Low-carbohydrate diets containing 113.8 g of protein per day result in significantly higher purine and acid load compared to standard hospital diets providing 68–69 g of protein per day, and high protein intake is a key driver of unfavorable nutritional profiles in these diets.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Diets with 113.8 grams of protein per day produce more purine and acid in the body than hospital diets with 68–69 grams of protein, and the higher protein amount directly leads to worse nutritional outcomes.
See the scientific wording
Low-carbohydrate diets in this study contain 113.8 g of protein per day, significantly higher than standard hospital diets (68–69 g/day), which contributes to both elevated purine and acid load, suggesting that high protein intake is a key driver of unfavorable nutritional profiles in these diets.
Eating more protein breaks down into amino acids that contain nitrogen and purines. The body turns these into uric acid and acidic compounds, which the kidneys must filter out. More protein means more of these waste products, forcing the kidneys to work harder and raising acid levels in the blood.
What the research says
1 studyStudy: Purine Content and Renal Acid Load Evaluation in Healthy Japanese Diets.
The study found that low-carb diets had almost twice as much protein as hospital meals, and that extra protein led to much more waste products that stress the kidneys and raise uric acid levels. So yes, the high protein is why these diets are harder on the body in these ways.
