As with everything in life, it is possible to overdo it. Even though plant-based protein is healthier than animal-based protein, if you eat more than 2 grams per kilogram of body weight per day, research suggests that this can cause long-term health problems. Symptoms of eating too much protein include intestinal discomfort, dehydration and nausea. The overconsumption of protein can increase a person’s risk of developing diabetes or osteoporosis! However, these findings were mainly associated with animal-based protein and haven’t been studied for plant-based protein alone.
