A study of 66,485 French women and their diets over a 14 year period has demonstrated that an acidic diet is linked to an increased risk of developing type 2 diabetes. An acidic diet is characterized by diets lower in carbohydrates and a higher in fat and animal protein. This diet included significantly more meat, fish, cheese, and bread (more in line with a standard Western diet). It also is higher in calcium, phosphorous and sodium and lower in magnesium. This group consuming this type of diet was over 50% more likely to develop diabetes than the low acidity or alkaline diet group, which consumed more fruit, vegetables, milk and coffee.
