“Want to go running?”

“Sorry, I’m allergic.”

It may sound like the perfect excuse, but can skipping the dreaded Phys Ed Mile or steering clear of running clubs actually be justified? Here’s some good (or bad) news — depending on that level of running love. People can in fact experience an allergic reaction to aerobic exercise, although it’s generally pretty rare[1].

People usually associate working out with an increased heart rate and a nice rush of endorphins — not hives, fainting, or an itchy rash[2]. But it could happen: Cholinergic urticaria, a common type of heat rash, can make an irritating appearance when there’s an increase in body temperature or when mast cells in the skin break down right before releasing sweat (read: working out). Studies suggest up to 11 percent of young adults experience this post-exercise hive attack, which is slightly more common in men. 

Even worse: There’s a running allergy that can be fatal. Exercise-induced anaphylaxis is a (very) rare allergy that occurs after eating certain foods like wheat, shellfish, and peanuts — and, like the name suggests, it’s triggered by exercise (especially running)[3]. Waiting at the finish line for sufferers: vomiting, difficulty breathing, and hives — notthe normal post-run experience. But before hanging up the sneakers and camping out on the couch, the chances of encountering this allergy are extremely low. Researchers estimate it only affects less than half a percent of the Western population (though methods of measuring prevalence haven’t been entirely pinned down yet)[4].

Running may not be everyone’s favorite fitness activity, but the “I’m allergic” excuse is reserved for those (un)lucky few. Besides the low risk of allergy, only one death from exercise-induced anaphylaxis has been recorded in the past 40 years. And there’s an easy way to prevent an outbreak from this food and exercise allergy: Work out before breakfast, since the reaction occurs only when exercise follows the food.

As for the itchy cholinergic urticaria, its cause is a sudden spike in body temperature, so a slow warm-up may help those temps rise slowly to avoid a sudden breakout[5]. Best to skip the Bikram Yoga, though. Or, mix things up and hit the pool to keep the body temperature cool[6].

Next time you're grocery shopping for your kids, think twice before adding a carton of fruit juice to your basket. The American Academy of Pediatrics has updated its guidelines on all juices, advising parents to pull back on how much they serve their little ones.

Previous recommendations said parents should wait to give their babies juice until after six months, but its latest update is suggesting that they wait one year. 

In fact, infants should only be fed breast milk or infant formula for the first six months. After six months, moms and dads can then introduce fruit to their diet, but not fruit juice.

“Parents may perceive fruit juice as healthy, but it is not a good substitute for fresh fruit and just packs in more sugar and calories,” said Melvin B. Heyman, MD, FAAP, co-author of the statement. “Small amounts in moderation are fine for older kids, but are absolutely unnecessary for children under 1.”

Scientists laid out instructions for older children, too. Toddlers who are ages 1 to 4 should only have one cup of fruit a day. Four ounces of that can come from 100 percent fruit juice, but it should be pasteurized and not labeled “drink,” “beverage” or cocktail.” 

For children ages 4 to 6, fruit juice intake shouldn't exceed four to six ounces a day. 

The amount increases just slightly for children ages 7 to 18. They can have up to two and a half cups of fruit servings, but only eight ounces of it should be juice. 

Top 15 crusaders for health in America's food industry

Wondering how this year's list stacks up against the last? Check out Top 15 Crusaders for Health in the Food Industry 2012.

Amongst all the junk food commercials and donut sandwiches, there are a handful of health heroes. These aren’t just people who eat organic greens for lunch and free-range eggs for dinner; they’re moving and shaking the way we think about our food, including where it comes from, the implications it has on our environment, and what our meals mean for our bodies. Here, we recognize 15 superstars (in no particular order) that have devoted themselves to improving American’s relationship with food.

 

1. Marion Nestle
Nestle has got her hand in nearly every facet of America’s food industry. Her blog, Food Politics, covers topics from nutrition and biology to health policy and food marketing. She’s been teaching nutrition for nearly four decades and currently teaches sociology, food studies, and public health at NYU. Nestle is the author of many books, but her latest — “Why Calories Count: From Science to Politics” — is all about understanding the intersection of health and food amidst all the mass marketing and misinformation put forth by major food manufacturers. Currently, Nestle updates her blog regularly and presents at universities and conferences on topics such as genetically modified foods and the role food companies play in our food system. (Photo: www.foodpolitics.com)

 

2. Michael Pollan
As one of the foremost activists for change in the overwrought food industry, Pollan is an outspoken and often controversial figure in the food and farming space. Though probably best known for his book “The Omnivore’s Dilemma” (which hung out on The New York Times Bestseller list for more than three years), Pollan has continued to write. In his most recent book, “Cooked”, Pollan explores how cooking connects us to plants, animals, farmers, and culture (amongst other things). (Photo by Ken Light)

 

3. Michelle Obama
After launching the Let’s Move! campaign at the start of 2010, the First Lady has made healthifying America’s eating habits (especially for kids) her job. The ultimate goal is to eliminate childhood obesity and help kids live healthier lives with good food and a little extra physical activity. This year, Obama held the second annual “Healthy Lunchtime Challenge,” where she asked children ages eight to 12 to whip up nutritious, tasty, and affordable recipes. Unfortunately, we weren’t invited to the White House kids’ “State Dinner” with the winner of this year’s challenge. (Photo: www.whitehouse.gov)

 

4. Mark Bittman
As an author and New York Times writer,Bittman likes to weigh in on what’s wrong with the American diet. A part-time veganhimself, Bittman is an advocate for the “flexitarian” diet — which means eating vegan during the day, but allowing for more flexible consumption after 6 pm. His super popular book, “How to Cook Everything”, is a go-to resource for basic kitchen skills. Not only does he push for humans to stay healthy, Bittman relentlessly encourages us to keep the environment happy and healthy, too. Oh, and in his spare time, he runsmarathons(Photo: www.markbittman.com)

 

5. Mike Bloomberg
As the mayor of New York City, Bloombergtakes his role seriously, making waves in the name of public health. From smoking bans tosoda bans, Bloomberg’s initiatives aren’t without controversy and backlash. Passionate about combating obesity, he’s pushed for salad bars and healthier menus in school cafeterias. Plus, he’s managed to eliminate trans fats from tons of restaurant items, and make it mandatory for chain restaurants to clearly post calorie counts on menus. We’re excited to see what goals Bloomberg sets (and reaches) next. (Photo: www.nyc.gov)

Turns out social media can make exercise contagious

Published: Saturday, May 13, 2017 @ 6:53 PM

We love a good workout buddy. You know, that ride-or-die friend who gives you an extra dose of motivation to roll out of bed for a 6 a.m. boot camp class. But what about those of us who’d rather sweat solo? Good news: You don’t necessarily need to work out with your friends to tap into the benefits, just as long as you have friends in your circle who work out.

As it turns out, exercise is kind of contagious. That’s the conclusion from a recent study published in the journal Nature Communications, which incorporated five years of data from about 1.1 million runners. That length of time and large sample size means the study is legit; however, there’s one hiccup: The study participants don’t exactly represent the population as a whole, since the data came from a particularly fit subset consisting of people who run and wear fitness trackers. Still, the findings are interesting.

Participants used an app with social sharing abilities so their friends could see the details of every run they went on (and vice versa). Researchers found the social media snooping served as motivation to get moving. If runner 1 ran an extra .62 miles, runner 2 felt inspired to run more too. And if runner 1 ran 10 minutes longer, runner 2 would go for a few extra minutes. The influence was strongest most immediately and seemed to cool over time. For example, runners were more influenced by what their friends did that day than by what they did three days ago.

The "contagiousness" of exercise wasn’t the same for everyone across the board. The correlation was strongest between men. Women also influenced guys, but to a lesser extent, and only women felt the positive peer pressure from other women.

So does this mean that most of us push ourselves harder to compete with those who are more athletic than us? Or are we more motivated to maintain our dominance over the people we’re better than? Researchers found both upward and downward comparisons at play, but the latter—the downward comparison—was stronger.

What does this mean IRL? Having friends who are healthy and fit (and willing to share the deets about what they do to remain healthy and fit) could give you extra incentive to exercise. “Who are the people you can surround yourself with who are going to push you to do better?” says Christian Koshaba, founder, CEO, and lead trainer at Three60Fit in Arlington Heights, Illinois. “You don’t have to be physically there together—it can be calling each other, sharing your Fitbit data, really anything that’ll push you like, ‘Oh there’s that number? Now I’m going to do better than that.’” 

Just make sure you find friends who are around the same fitness level as you. The study's researchers found competing on a close-to-level playing field had the strongest influence. Plus, trying to compete with someone who’s out of your league could backfire if you end up injured, Koshaba says. In general though, “the positives outweigh the negatives when you’re striving to be better,” he says.

Of course, to make the findings of this study work for you, you have to be willing to share your stats. Koshaba says some of his clients track how much they’re lifting and how fast they’re running in a shared Google doc. Or you can embrace the social features of your favorite exercise apps so you know how you measure up. Here are three we’re fans of:

  • Nike+ Run Club: Pace, elevation, heart rate, splits—all of your stats are logged within the app. Follow up the workout by sharing your run (plus any photos you took along the way) with your entire social network or just with those within your Nike+ circle. The app’s leaderboard feature also lets you tag your miles against challenges to see where you stand.
  • Runkeeper: Start a virtual running group (which is easy to do, thanks to this app’s community of 50 million runners) and knock out the running goals you set as a team, such as running twice a week for one month.
  • Strava: Your workout will be recorded on your Strava feed, where friends can cheer you on and where you can see what others are up to. That’ll come in handy on those days when you’re tempted to skip the workout altogether.

The Bottom Line

At the end of the day, it's cool to look into the science behind something that's so relevant and relatable, but it all comes down to what motivates you. Posting about fitness on social media isn't always vain; it's an easy and accessible way to hold yourself accountable and give or get inspiration to move. If you're the type of person who's motivated by competition or numbers, great! But if following your friends' fitness habits turns toxic, causes you to compare yourself in a negative way, or makes you feel bad about your own performance, then it's time to unfollow for your own good.
