But, I will say, there’s good reason the advice stuck around for so long. And that’s because not all oils are created equal: Some oil options out there certainly do contribute to clogged pores. It’s a concept we know in the beauty industry as “comedogenic and noncomedogenic.” And that’s why if you do have acne-prone skin, you should always look for noncomedogenic oils when adding them to your routine. “Spectrum” is an important word in that last sentence....

I know this concept through and through. I’ve dedicated my life to helping others transform their relationships by changing their internal realities. Even though all this is true, you better believe I still felt annoyed, frustrated and disheartened when the man I was intimately involved with began to feel “unavailable” to me. Yes. Again. I realized that I had more work to do. (Ugh.) To understand why this man began to feel unavailable to me, I first had to understand myself better....

In fact, olives pack such a healthy punch that working more of them into your diet is one of those no-brainer health-boosters nobody should miss out on. With all the varieties there are to choose from—roughly 500 or so—there is an olive to suit virtually every taste. Better yet, those delicious polyphenols help cut oxidative stress in the brain and can help boost memory. In other words, olives are also a great way to feed your head....

Medical school was the next phase of life that really taught me how to get to bed—anytime, anywhere I could. But my sleep wasn’t as deep or restorative because I was always falling asleep a little worried that I was going to be called to attend to an emergency situation. It took several years after I was no longer the “on-call doc” to be able to fall asleep without this worry, which definitely made my sleep depth and quality much better because I felt safe enough to let myself go deep....

As it turns out, vitamin D actually supports gum and tooth health and is predicted to help manage gingivitis and gum disease. Seriously, this research might have you exchanging your mints for a quality vitamin D supplement! Gingivitis is the medical term for inflammation of the gums1, and its symptoms include red, swollen, and bleeding gums; sensitive teeth; receding gums; and bad breath. If gingivitis progresses, periodontitis—a severe gum infection that can lead to tooth loss—can develop....

As people bring alt-milk into their homes, they’re also bringing questions. Specifically, what’s in it? Plant-based milks often have long lists of ingredients. Some, like water and almonds, are easily recognizable; others, like gellan gum…not so much. Gellan gum is a vegan thickening agent added to foods to create and maintain a desired consistency. “It’s found in nature, growing on water lilies,” explains Lauren McNeill, R.D., MPH.
