Hello, reddit! I’m Vasanti Malik, a research scientist in the Department of Nutrition at the Harvard T.H. Chan School of Public Health and the director of the Global Nutrition and Epidemiologic Transition Initiative at Harvard. My research focuses on evaluating dietary risk factors for obesity, type 2 diabetes and cardiovascular disease with an emphasis on diet quality. More recent research interests include studying nutritional drivers of the global obesity and diabetes epidemics in countries undergoing epidemiologic transition.
In January, U.S. officials released a new set of Dietary Guidelines—broad advice on how the nation should eat. These new Guidelines included some significant changes from previous versions, including the recommendation no more than 10% of a person’s daily calories come from added sugars. This is the first time the Guidelines set an upper limit for added sugar intake. Another important change is the removal of an upper limit for total dietary fat, and a greater emphasis on consuming certain types of fat.
But there were also some omissions, which have drawn criticism from nutrition scientists. The Dietary Guidelines Advisory Committee—a group of scientists who made recommendations about what should be included in the Guidelines—called for specific guidance regarding reduced consumption of red meat and sugar-sweetened beverages. These were not included.
Overall, these Guidelines do represent an important step towards helping Americans identify healthy dietary patterns.
I’ll be here from 11:00 a.m. to 1:00 p.m. EST to answer your questions about the Dietary Guidelines and nutrition; Ask Me Anything!
