For many, Oct. 31 is a time to delight in the classic indulgence in Halloween candy. But while these treats can be immediately rewarding, it is also important to recognize the nutritional and psychological implications of the holiday centered around an overload of sweets.
Prof. Laura Bellows, division of nutritional sciences, is helping families develop healthy eating and physical activity habits through her research and community work.
The USDA Food Guidance System myplate.gov offers comprehensive and individualized diet suggestions based on age, sex, height, weight and activity level. Myplate.gov works to integrate the five food groups of vegetables, fruits, grains, protein and dairy into everyday diets. “Make half of your plate fruits and vegetables,” “Make half of your grains whole grains” and “Vary your protein routine” are just a few of the recommendations to keep in mind when loading up your plate. Notably, myplate.gov encourages a movement towards healthier and balanced eating that is not about haves and have nots, but rather about the overall, general composition of what is eaten. The website also dives into greater detail regarding the health benefits of each food group, serving sizes, and general nutrition facts.
Cornell hosts Summer Institute for Systematic Reviews in Nutrition for Global Policy Making alongside Cochrane and the WHO this past summer.
Content Warning: Discussion of dieting and restriction
As a senior in nutritional sciences, simply stating my major usually results in some comment from somebody about their diet, be it defensive or inquisitive. I’m usually unbothered by these encounters, and I view eating as a deeply personal activity, since people’s eating habits can be driven by complex factors. However, there is one topic that comes up so often that I feel it’s necessary to make my opinion abundantly clear: You probably should not try the keto diet. Even for people not specializing in nutrition, I don’t think anyone will fight me when I say that protein is the golden child of nutrition. Compared to its macronutrient siblings (carbs and fat), protein can essentially do no wrong.
What do your teeth, brain, mood and gut all have in common? Unsurprisingly, it turns out one answer is almost everything. They are, after all, interconnected and essential aspects of your body and life. The other, often overlooked answer, however, is food. The COVID pandemic put into perspective how little control we have over certain parts of our health, but quarantine was sobering, proving we don’t have to be “an inert chunk of randomly assembled molecules drifting wherever the universe blows” us. In fact, the decisions we make about our food give us resounding leverage over our health.
Trillions of microbes inhabit the human digestive system, constituting such a critical part of our health that many researchers have taken to calling the vast, microscopic population the “hidden organ.” But despite weighing as much as five pounds and collectively containing 200 times the number of genes as the human genome, scientists still aren’t sure how these gut microbes — which include bacteria, fungi and viruses — affect human health.
“Nutrition is about whole foods, not pills and procedures,” Campbell said. “If we can adopt this wholist nutrition lifestyle, which promotes preventative health, diseases won’t arise so often. If there is no disease, there is nothing that we need to treat.”
Cornellians might be quick to share derisive Okenshields memes, but behind Cornell Dining’s offerings are a slew of careful decisions designed to ensure nutritious and healthy options, according to Michele Lefebvre, Cornell Dining’s director of nutrition management.
