Read MoreMinimalist Shoes and Stronger Foot Muscles
Minimalism is trending in many areas of life, including athletic shoes, with many fans touting numerous benefits. But does the evidence support the hype? Yes, according to research findings published in Medicine & Science in Sports & Exercise (2018; doi:10.1249/MSS.0000000000001751).

Read MoreIs It Time to Replace Fruit Juice With Whole Fruit?
It’s not breaking news that consuming too many sugar-sweetened beverages is bad for our health. Now, findings from a large cohort study involving more than 13,000 American adults ages 45 years and older suggests that drinking glassfuls of OJ may not be such a good idea either.

Read MoreProcessed Food Linked to Weight Gain
Over the past several decades, fast-food and processed/packaged foods made with cheap ingredients like white flour and salt have come to dominate the American diet.

Read MoreSoda Tax: Drink Pop, Pay More
Love sodas or loathe them, it’s becoming harder to ignore the impact that a “soda tax” can have on consumption rates. A tax of 1.5 cents per ounce of sugary drinks sold in Philadelphia, implemented in 2017, resulted in a 51% drop in sales compared with the previous year, although that figure was partially offset by a rise in sales in neighboring no-tax towns, according to research published in JAMA.

Read MoreDelicious Danger? A Research Update on Artificial Sweeteners
In human evolution, the preference for sweet taste was beneficial, since it helped to direct newborns toward eating nutritious food. Recent advances in medicine and nutritional sciences suggest that reducing intake of products high in sugar and salt could improve public health. Nevertheless, many people adore sweets and, therefore, artificial sweeteners (AS)—food supplements with chemical structures different from sugar—made their way onto the market.
Read MoreHaving the Bone Health Talk With Clients
Clients may ask you about calories or how to “tone,” but how often do they ask questions about bone health and osteoporosis? If clients aren’t asking these questions, they should: 54 million adult Americans are at risk of breaking a bone (NOF 2019a). You probably already know that people who have osteoporosis should do weight-bearing exercises to slow the degradation and ease the effects. However, most people are given no more explanation than that. You may be in a position to offer answers to some of your clients’ questions.
Read MoreMuscle Cramps? Find Out Why
Muscle cramps can stop athletes in their tracks. Although they usually self-extinguish within seconds or minutes, the abrupt, harsh, involuntary muscle contractions can cause mild-to-severe agony and immobility, often accompanied by knotting of the affected muscle (Minetto et al. 2013). And cramps are common; 50%–60% of healthy people suffer muscle cramps during exercise, sleep or pregnancy or after vigorous physical exertion (Giuriato et al. 2018).

However, all the talk has created a mythology around the “right” way to eat. It’s time to separate myth from reality by looking beyond opinions and focusing on the science.

They might be blue, but there appears to be nothing sad about the heart-healthy benefits of blueberries. When British researchers provided 138 overweight and obese people, ages 50–75, with 150 grams (about 1 cup) of blueberries daily or a placebo for 6 months, they found participants eating the berries experienced various improvements in cardiovascular health, including a reduction in arterial stiffness and improved endothelial functioning.

Read MorePut Down the Phone While You Grocery Shop
It’s not a good idea to be a distracted driver when pushing your shopping cart. A study with modern-day relevance found that people who used their phones for “shopping-unrelated” tasks—like scrolling through a social media feed or volleying text messages with a friend—purchased more unplanned items than people who didn’t use their phones while grocery shopping. And were those items a head of broccoli or a pint of blueberries? No, the purchases were mostly nutritionally poor, packaged foods.
