A cooking traditionalist, I’m skeptical of any hint of a “pushing food to be more” approach. Why mess with perfection? But, whether in cooking, in raising our kids, in finding new careers, or in our most intimate relationships, we can invite that new person, relationship, skill, or food to become just a bit “more” by […]
Mom was right: It really is the most important meal of the day.
For 20 years, researchers at the University of Minnesota School of Public Health followed 5,000 men and women, looking specifically at their breakfast habits: what they ate and when. The results, presented recently at the annual meeting of the American Diabetes Association, found that people who ate breakfast every day were significantly less likely to become obese or develop type 2 diabetes than those who ate breakfast three times a week or less. These findings are significant, if not particularly surprising. Haven’t our mothers been telling us to eat our breakfast for years?
“This study affirms everything nutritionists have been talking about,” says John Bagnulo, PhD, MPH, who teaches nutrition in Kripalu’s Healthy Living programs. “When people eat breakfast, and in particular foods that give them less of what I like to call a ‘blood sugar tsunami,’ they make much better food choices throughout the day.” This includes avoiding foods containing sugar, not overdoing it on caffeine, and practicing portion control. “It’s all related to blood sugar,” says John. “If someone misses breakfast, their blood sugar levels come way down. They’re starving by 10:30 or 11:00, and because they haven’t eaten all morning, they crave foods that have a higher glycemic index,” like muffins, breads, candy, or pasta. Then they crash again by 1:00 pm—and look for yet another sugary pick-me-up. Sound familiar?
A study recently published in the medical journal Atherosclerosis reported that a diet rich in whole eggs is as artery-clogging as smoking. Researchers surveyed about 1,200 middle-aged male and female patients—all of whom had suffered a stroke or “mini-stroke”—about their egg yolk consumption, smoking, exercise habits, and other lifestyle factors. They concluded that the top 20 percent of egg consumers had a narrowing of the carotid artery that also appeared in two-thirds of the smokers. Of course, the media jumped on the catchiness of being able to call out that “Eggs are Nearly as Bad for Your Arteries as Cigarettes” and “Your Breakfast Eggs Are Going to Kill You,” as the Atlantic and others did.
But what most media reports didn’t point out—or buried after the alarmist headlines—is that the study was incomplete, says John Bagnulo, PhD, MPH, who teaches nutrition in Kripalu Healthy Living programs. “The way that eggs are cooked is a huge factor,” he says. Certain high-temperature cooking methods—including frying and scrambling—oxidize the cholesterol into a substance known asoxysterol, a molecule known to accelerate both heart disease and conditions such as Alzheimer’s and dementia. More, though, he worries about how the study’s information was gathered and presented. “Research like this is not good science,” he says. “I might be able to see the detrimental weight of eating fried or scrambled eggs as comparative to smoking, but even that seems a stretch.”
The Paleo diet trend is catching on.
It used to be called dieting. Now our food restrictions, most of them self-imposed, are called a lifestyle choice. From the vegetarian, vegan, and dairy-free to nut-free, low-fat, no fat, no carb, and raw, pretty much everyone’s not eating something.
The newest abstainers may be followers of the Paleo diet, also known as the “caveman diet” and populated by Loren Cordain, PhD, author of three books on the topic: The Paleo Diet, The Paleo Diet for Athletes, and The Dietary Cure for Acne. Cordain and other proponents of the Paleo diet argue for a return to prehistoric ways of eating, pointing out that the human body was designed to thrive on—and best digest—the foods available to us when we were hunter-gatherers: meat, vegetables, and fruits, but not dairy or grains. Before the invention of agriculture and processed foods, we were fitter and less disease-stricken, he argues; those who’ve had success on a Paleo diet, meanwhile, credit it for everything from losing weight to lowering blood pressure and eliminating acne. Like nearly any other restrictive way of eating, including veganism, the Paleo diet has dedicated followers and ardent detractors.
In this edition of Ask the Expert, John Bagnulo, PhD, Kripalu Healthy Living faculty, addresses questions on whether to eat or avoid common ingredients including fish, eggs, stevia, and whey.
The jury still seems out on the benefits vs. harm of eating fish. Based on the newest available evidence, what are the biggest risks, and do you recommend eating it at all?
I do advise people to eat fish. It offers nutrients that are more elusive in a vegan diet, without the health compromises that other sources of animal protein require you to make. I highly recommend sardines and mackerel as they are small, very clean, and packed with beneficial oils and trace minerals. They are on my top-five food list, in spite of being animals. I recommend that people avoid all big fish, especially large varieties of tuna and swordfish. These are tainted with PCBs, which I am much more concerned with than mercury.
Is there any harm in eating just egg whites (not the yolks)?
