Ask the RD
Question: I have a sensitivity or allergy to tomatoes. My mouth and esophagus get itchy and sore when I eat them. Is there any way to make tomatoes less irritating? Is there a good substitute for tomatoes in recipes?
Answer: You may suffer from oral allergy syndrome (OAS), a relatively common reaction to plant foods, including tomatoes. People who have pollen allergies are more likely to have OAS (Asero 2013) because they react to similar proteins in vegetables, fruits and/or nuts.
Time to Snub the Clubs?
The prospect of getting extra bang for their food buck has more people perusing
warehouse-style club stores like Costco and Sam’s Club. But the urge to stockpile large amounts of food in the house may lead to calorie overload.
Portion Distortion
No wonder social media feeds are packed with pictures of overflowing smoothie bowls: It appears people feel the types of foods they consume play a bigger role in their health goals than the volume they eat. As a result, a study from Vanderbilt University published in Management Science suggests that those who are trying to maintain a healthy body weight or wishing to shed a few pounds might be prone to overeating “healthy” items like nuts, granola and avocados. The upshot: The public should be educated about practicing portion control—for foods of all kinds.
Snacks Are a Workplace Hazard
Many people can’t resist the temptation of homemade chocolate chip cookies in the break room or leftover Halloween candy circulating among the cubicles. A Centers for Disease Control and Prevention study of 5,222 employees across the U.S., using data from the U.S. Department of Agriculture’s National Household Food Acquisition and Purchasing Survey, documented this challenge.
Twitter’s Former CEO Shuts Down Fitness App Startup
Unable to solve the challenge of how to support positive behavioral change, Dick Costolo, former CEO of Twitter, decided in February to shut down Chorus, a social fitness app that began beta testing in April 2017. The app was designed to use a “chorus” of friends as team members and have them support each other in achieving self-proclaimed weekly fitness or other health-related goals.
Exercise and the Gut Microbiome
New research suggests that endurance exercise positively affects the gut microbiome, but only for lean individuals and only for as long as exercise continues. Researchers at the University of Illinois at Urbana-Champaign conducted the study with 32 sedentary men and women—some lean, some obese. The purpose was to explore the impact of endurance exercise on the composition, functional capacity and metabolic output of gut microbiota. Investigators collected samples from the subjects before and after 6 weeks of exercise, then after 6 weeks of no exercise.
Obesity Linked to Lack of Sleep in Childhood
Enforcing bedtime rules may be an important factor in helping kids maintain healthy weight levels. A comprehensive research review of 42 studies with 75,499 participants, conducted by University of Warwick researchers in Coventry, England, found that short sleep durations in infants, children and adolescents were a risk factor for gaining weight and developing obesity. Data analysis showed that children and teens who slept less than others of the same age gained more weight as they grew older and were more likely to become overweight or obese.
The Importance of Exercise for Addiction Recovery
Substance use disorder can wreak havoc on people’s lives. Fitness activity can be a
transformative way for those in recovery to heal, rebuild their lives and find a community of healthy supporters.
According to a study published in Mental Health and Physical Activity in 2011, patients with substance use disorder who exercised while in recovery reported feeling greater strength, improved health, a sense of accomplishment, and increased confidence about staying clean and sober.
Comprehensive Research Project on How to Create an Exercise Habit
24 Hour Fitness® is partnering with the University of Pennsylvania Behavior Change for Good Initiative [BCFG] to support research into what works best for creating lasting exercise habits. With an interdisciplinary team of world-renowned researchers, the BCFG addresses the broader question of how to make positive behavior change stick in aspects of life related to health, education and savings.
Study Launched on Molecular Changes Related to Exercise
In April, Louisiana State University researchers in Baton Rouge held a training for 120 scientists to kick off a national research consortium designed to create a comprehensive map of the body’s molecular responses during and after exercise. The purpose of the $170 million, multicenter, 6-year research project is to promote understanding of how physical activity improves health and prevents disease.
The Connection Between Inactivity and Obesity
Can we say that inactivity and obesity are directly related? Scientists are still addressing this issue. The 2018 Physical Activity Council Participation Report shows that 82.4 million people—28% of the American population—are inactive. At the same time, the Centers for Disease Control and Prevention reports that more than one-third (36.5%) of U.S. adults are obese (NCHS Data Brief, No. 219, November 2015).
On This Day in Fitness History
On September 25, 1974, the first modern triathlon event was held in San Diego, sponsored by the San Diego Track Club. Prior to this, other three-sport events existed but did not feature the swim-bike-run combination. The first triathlon included a 6-mile run, a 5-mile cycle and a 500-yard swim. In 1978, The Hawaii Ironman Triathlon® debuted with a 2.4-mile open-water swim, a 112-mile bike race and a 26.2-mile marathon run.

Exergaming May Improve Independence Among Older Adults
Maybe you’ve thought about integrating exergaming—exercise combined with video games and other elements of technology—into some of your classes or sessions. Don’t forget to include older adults. A recent study found that seniors with mild cognitive impairment (MCI), a precursor to Alzheimer’s, showed significant improvement in certain complex thinking and memory skills after exergaming.
Equal Calories Burned ≠ Same Results
Many people fixate on the number of exercise calories they burn. New research, sponsored by Les Mills International, shows that even when two group fitness activities (indoor cycling and a resistance workout) were matched for duration and caloric expenditure, they did not have equivalent metabolic effects—which could influence long-term training results. Lead study author Nigel Harris, PhD, said, “The type of exercise used to burn those calories . . . impacts the long-term positive effects that exercise has on the body.”
How to Help Participants Find Flow
For a moment, think about your own workouts. Tap into that feeling of being completely absorbed in your favorite fitness routine. Everything else fades away, and your entire focus is on the present moment. You feel confident in your body’s abilities, you’re challenging yourself, and you find great meaning in what’s happening now. You’re in the zone. Before you know it, your workout is over, and you can’t wait to do it again.
An Eye on Vision Health
When it comes to muscles, we rarely think about our eyes, and yet the eye is the fastest and most active muscle in the human body (VSP 2018). We say “in the blink of an eye” for a reason! While you probably don’t program “eye lifts” into your strength training routines, exercise does support healthy vision. Read on to find out more about the benefits, along with a few fun facts you can share with clients to further inspire them to keep moving.
Pilates for Recreational Athletes
Professional athletes of all kinds have discovered that adding Pilates to their training can improve performance, reduce injury, speed recovery, and help their hardworking bodies stay balanced and healthy (Caple 2016; Knowlton 2016; Saxon 2016). Pilates—a whole-body exercise system that can help you develop strength, functional flexibility, coordination and balance—can offer those same benefits to recreational athletes. A well-rounded program, particularly one offered in a fully equipped Pilates studio, can do wonders for athletes of almost any age, ability or sport.
