AHA: Meal Frequency, Timing May Affect Cardiovascular Health
HealthDay News — A new statement from the American Heart Association (AHA), published online January 30 in Circulation, highlights what's known – and what's not – about meal timing and cardiovascular health.
The report is a response to the growing evidence that timing matters when it comes to cardiovascular disease risk, lead author Marie-Pierre St-Onge, PhD, an associate professor of nutritional medicine at Columbia University in New York City, told HealthDay. The various organs of the body have their own "clocks," St-Onge explained, and that may affect how we handle food at different times of the day and night.
A number of studies have found that breakfast eaters are generally healthier than breakfast skippers: They tend to weigh less, have better blood pressure and cholesterol numbers, and have lower risks of type 2 diabetes and cardiovascular disease, according to the AHA. Studies that track people in the real world have found that those who eat more often during the day have a lower risk of obesity and better cholesterol levels.
The statement lacks specific rules, such as "never eat after 8 p.m.," or "everyone should eat breakfast." It does, however, suggest that people spread out their calories over a "defined" period of the day – as opposed to either eating a lot over a short period, or grazing from morning until night. Based on the evidence, the AHA says, it's probably a good idea to consume most of the day's calories earlier in the day.
