Diet-related chronic diseases have reached a critical juncture in the U.S.

Nearly half the population has prediabetes or diabetes. Over 40% are overweight or obese. One in nine people over the age of 65 has Alzheimer’s disease, the development of which researchers are exploring the potential role of diet. Poor diet is also linked to poor mental health, cardiovascular disease and cancer. It was responsible for nearly 1 in 5 deaths in the U.S. and accounted for over US$140 billion in U.S. health care spending in 2016.
