They’re not the only omegas out there, though—and the next best-known essential fatty acids, omega-6s, don’t have quite as sunny a reputation. Omega-6s aren’t inherently bad. In fact, your body needs some omega-6s (in fact, there’s a daily nutritional requirement for omega-6 linoleic acid1 because our body can’t synthesize it). However, there’s a very legitimate reason these other omegas have found themselves in the hot seat lately. Here’s what to know about these somewhat confusing fats....

I started experiencing low self-esteem as a result and was no longer as social as I once had been. I wanted to take these symptoms head-on, so I decided to drag myself to the doctor. He explained that PCOS occurs when a woman’s hormones are out of balance, which can lead to problems with fertility and menstrual cycles as well as weight gain and cysts on the ovaries.

You can also tell a spider plant from its tell-tale thin, grass-like leaves that come in beautiful variegated patterns. The Chlorophytum comosum ‘Vittatum’ has leaves with white/yellow centers with green outlines, while the Chlorophytum Comosum ‘Reverse Variegatum’ leaves have green centers with white/yellow outlines. The Chlorophytum Bonnie’s leaves come out hilariously curly. When a spider plant is happy, these leaves will grow very quickly. Native to the coast of West and South Africa, the spider plant is relatively hardy and can withstand a wider range of temperatures than some other popular houseplants....

But when your mitochondria crash, so does your ATP production1. Translation: Goodbye, energy and hello fatigue. “When mitochondria falter, cells lose power2, just as a flashlight dims when its batteries weaken,” says Charles W. Schmidt, M.S. Mitochondrial dysfunction creates fatigue3, but it also contributes to almost every chronic disease4. The bad news is that our mitochondria start operating less optimally as we age4. At the same time, many things we are exposed to daily—including environmental toxins, pesticide-loaded conventional foods, and drinking water that can sometimes carry unsafe levels of toxic chemicals—are also a hit to your mitochondria....
