There are scientific discoveries that are the result of serendipitous accidents. The “most beautiful of plastics”, a popular polymer in the early 20th century made from a protein found in milk, was accidentally invented by a cat. Proteins, of course, are better known for their nutritional necessity than as a component in plastic buttons. With rising obesity in America and opportunistic fad diets, most see proteins as the macronutrient that’s better for weight loss and muscle building, compared to carbohydrates and fats. As people clamor to increase their protein consumption, sales for protein supplements have skyrocketed in America. While there is nothing wrong with increasing protein intake per se, the health outcomes of consuming protein supplements can be murky.
