"Roughly six hours after your last bite, your body switches from digestion to housecleaning: Envision Dyson vacuums cleaning out cellular debris, which stimulates the growth of new cells throughout the body," Dr. Peake says. "The scientific word for this is 'autophagy' (self-eating/cleaning), the discovery of which was rewarded with the 2016 Nobel Prize in medicine and physiology."
David Ludwig, M.D., Ph.D., professor at Harvard Medical School and author of Always Hungry?, says that the sugar in juice is digested super fast because there are no other nutrients (like fat or protein) to slow it down. That leads to a giant blood-sugar spike and subsequent crash that leaves you craving sugar and carbs, says Ludwig. And since we drink juice even when we’re not hungry, all those calories go straight to storage, he says.
Flailing in the swell of bestselling diet books, infomercials for cleanses, and secret tips in glossy magazines, is the credibility of nutrition science. Watching thoroughly-credentialed medical experts tout the addition or subtraction of one nutrient as deliverance—only to change the channel and hear someone equally-thoroughly-credentialed touting the opposite—it can be tempting to write off nutrition advice altogether. This month we hear something is good, and next we almost expect to hear it’s bad. Why not assume the latest research will all eventually be nullified, and just close our eyes and eat whatever tastes best?
Talk about heart ache: high blood pressure stresses arteries, and can make you more susceptible to heart disease. To eat to lower your blood pressure, you just need to focus on heart-healthy bites. The American Heart Association recommends loading up on fruits, veggies, whole grains, low- or non-fat dairy, beans, lean meats, and fish. Bonus: no one's ever gotten fat eating more kale and beans.
