Heavy Meat Eaters Eat Veggies When Given the Choice

The meat industry is one of the leading drivers of the recent spat of fires in Brazil, and globally the meat industry is a major factor in the climate crisis. If we’re going to avert catastrophe we’re going to need people to change their diets in one simple way: cutting out meat. If people don’t want to cut out meat entirely, that’s ok, as long as they reduce their meat consumption. As a society we can reduce everyone’s meat consumption very easily by just providing meatless meals in cafeterias.

Emma Garnett and her colleagues at the University of Cambridge, UK, collected data on more than 94,000 meals sold in 3 of the cafeterias at the university in 2017. When the proportion of meatless options doubled from one to two of four choices, overall sales remained about constant. But sales of meat-containing meals dropped, and sales of vegetarian meals, such as “wild mushroom, roasted butternut squash and sun blushed tomato risotto with parmesan”, rose 40–80%.

A Diverse Diet may Starve some Cancers

Cancer is awful and destroys far too many lives, but what if we can help people survive by augmenting their medicine with better diets? New research is revealing that a diverse diet could help people essentially starve cancer. To be very clear: a diet change will not defeat cancer. The key takeaway here is that some medication can be more effective if matched with a diet that promotes healthy cells in your body which also stymies the development of cancer cells. We still have a long way to go when it comes to fighting cancer, but new developments every year help us on this healthy journey.

Seventy percent of T cells — the body’s most potent cancer-fighting immune cell — live along the gastrointestinal tract, making them highly sensitive to what you eat and what medicines you take. Over the last five years, scientists have started to understand how the gut microbiome influences T cells and the immune system, and how that can affect health and disease.
The general consensus seems to be that more diversity in gut bacteria is better, and, many of the studies looking at what the gut of a cancer treatment responder looks like differ in terms of which types of bacteria are present, driving home that no single strain is overly important. The one consistent finding is that people with more diversity in their gut bacteria seem to have better responses to immunotherapy.

Learning Junk Food Marketing Manipulates, Teens Consume Less

Healthy eating can be a challenge when millions of dollars are spent everyday trying to convince us to eat junk food. It turns out that telling the truth to teens may help them eat healthier. Informing teens about the financing and exploitation that goes into big food gets them to think critically about the marketing and rebel against it. Plus, starting healthy eating practice in the teenage years sets them up for a lifetime of health.

In the study, “A Values-Alignment Intervention Protects Adolescents from the Effects of Food Marketing,” published today in Nature Human Behaviour, Chicago Booth’s Christopher J. Bryan, University of Texas at Austin’s David S. Yeager, and Booth PhD candidate Cintia P. Hinojosa find that reframing how students view food-marketing campaigns can spur adolescents, particularly boys, to make healthier daily dietary choices for an extended period of time. The method works in part by tapping into teens’ natural desire to rebel against authority.

Among the two biggest findings in the experiment: The intervention produced an enduring change in both boys’ and girls’ immediate, gut-level, emotional reactions to junk food marketing messages. And teenage boys, a notoriously difficult group to convince when it comes to giving up junk food, started making healthier food and drink choices in their school cafeteria.
“One of the most exciting things is that we got kids to have a more negative immediate gut reaction to junk food and junk food marketing, and a more positive immediate gut reaction to healthy foods,” said Bryan.

Active People Naturally Crave Healthier Foods

Want to eat healthier but lacking motivation? Start being more active and you’ll find that picking healthier foods will get easier. A least that’s what participants found in a recent study, and there’s no reason to expect different results for you. Researchers took people who had a sedentary lifestyle and just asked them to workout a little. Without instructions the participants started to eat healthier just because they were more active.

“The process of becoming physically active can influence dietary behavior,” said Molly Bray, corresponding author of the paper and chair of the Nutritional Sciences department at UT Austin and a pediatrics faculty member at Dell Medical School. “One of the reasons that we need to promote exercise is for the healthy habits it can create in other areas. That combination is very powerful.”

“Many people in the study didn’t know they had this active, healthy person inside them,” Bray said. “Some of them thought their size was inevitable. For many of these young people, they are choosing what to eat and when to exercise for the first time in their lives.”

Don’t Clean Your Plate

Many of us were raised with mentality of “cleaning” our plate at the end of the meal; basically, it means finishing all the food on your plate. Some researchers wondered if this leads to unhealthy overconsumption of food, and indeed it does. There’s some simple things you can do to avoid eating too much like making smaller servings, not finishing everything just because it’s on your plate, and you can just use smaller plates.

“Many of us were raised with this ‘clean your plate’ mentality, stemming from a desire to ensure one is not being wasteful or their children are eating well; however, this can also lead to overconsumption,” Haws said. “So, one could argue that good advice for someone trying to manage their food intake would be not to clean their plate.”
Haws and her co-authors were interested in exploring how the clean-plate phenomenon, called “consumption closure,” affects our desire to keep eating more than we should or want to when there’s just a small amount left, “The questions we had were: Is there something special about having this small quantity left over, and what processes do people use when justifying continued consumption or deciding whether or not to continue consuming?”
