When energy dips late in the day, it’s tempting to grab chips, candy, or pizza for a quick boost. But dietitians warn that not all carbohydrates are created equal. The simple carbs found in sugary or highly processed snacks burn off fast, often leaving you craving even more. Instead, experts recommend keeping these foods to a minimum and choosing healthier carbs from fruits, whole grains, and starchy vegetables for steadier energy.

Good oral health, meanwhile, isn’t about how much you spend on a toothbrush. Researchers at the University of Amsterdam say effective brushing comes down to technique, not price. Whether you use a basic manual brush or a high-frequency sonic model, the key is brushing twice a day for two minutes.

And if you’ve ever felt happier around a dog, science may have found the reason. Researchers at Azabu University in Japan report that dogs can positively influence the human microbiome—the community of microbes living in our bodies. These microbial changes are linked to better mental well-being. The researchers say children, in particular, may benefit when they grow up with a family dog in the home.

Together, these studies highlight a simple truth: small daily choices—from what we eat to how we care for our teeth to the pets we live with—can have a meaningful impact on our health.
