It is always important to be mindful of not getting dehydrated. We know dehydration causes many unpleasant side effects. However, you need to know that there is such a thing as overhydration, and it can be dangerous too. A report on the dangers of overhydration was compiled by sports medicine experts and presented at the 2015 CrossFit Conference on Exercise-Associated Hyponatremia in California. In the report, sports medicine experts present their view that overhydration actu

Walnuts stand out as the top nut for protecting brain health. Here’s what the science says about their role in lowering dementia risk. Key Points Certain lifestyle habits, like eating a nutritious diet, can lower dementia risk. Walnuts are rich in healthy fats, antioxidants and fiber, which may protect both your brain and heart. For a healthy brain, follow the MIND diet, stay physically active, sleep well and challenge your mind. Every three seconds, someone in the world is d

There is a window of time in which sufficient physical activity can help mediate some of the damage caused by eating an unhealthy meal. I’ve previously discussed studies that show a single meal high in saturated fat can impair artery function in men, as measured in the arm, but what is more concerning is blood flow to the wall of the heart. Researchers randomized men to eat either a high-fat meal that was more than 60% fat, half of it saturated, with more than an egg’s worth

What happens within hours of eating a high-fat meal? We are only as old as our arteries. What can we do to preserve arterial function as we age? A poor diet and sedentary behavior can lead to adverse aging processes, like impairment of the little power plants in our cells, which can result in free radical formation, oxidative stress, and inflammation, which lead to the artery dysfunction that can end in cardiovascular disease that ends us. In a series of videos I did about a

What happened when ultra-processed foods were matched for calories, sugar, fat, and fiber content in the first randomized controlled trial? In the United States, “junk food” is often used to describe less-healthy foods, like candy, ice cream, and chips, but there isn’t a consistent definition, so nutrition researchers came up with the concept of ultra-processed. The term “ultra-processed food”—if you want to call it that—describes industrial formulations that are typically seen

Not only is it more convenient, but when it comes to quality and food safety, some fish are best purchased frozen. Key Points Seafood is so perishable that buying it frozen often guarantees the freshest product. Freezing is an important step in eliminating seafood parasites. Some fish are a better value frozen, and some “fresh” options on the seafood counter are merely defrosted. Frozen food gets a bad rap, but when it comes to seafood, you’re often better off buying froz

Do you still feel tired even when you get the prescribed seven to nine hours of sleep a night? By now, you’re quite aware of the detoxifying and restorative benefits of sleep: Lasting energy Clear thinking and decision-making Weight loss Improved immune function Mood stability and emotional resilience Stress reduction (which helps reduce system-wide inflammation) Reduced risk of chronic diseases, such as heart disease and diabetes Yet it can be extremely frustrating feeling l

In the alternative health world, we have a tendency to focus on superfoods — those products of nature that improve our health and nurture our bodies. Often, we skip over those foods which have the opposite effect. These not-so-superfoods can harm not only your health in general, but also the sensitive state of your eyes and vision. That’s because certain foods can increase inflammation in the body, raise blood pressure, reduce nutrient absorption and harm your microbiome… all

The randomized trials are stronger than the skeptics admit, and the case against chlorhexidine is stronger than your dentist mentions. With a quick how-to from Dr. Kansara. Name one thing in your kitchen you can use to clean your mouth. Three, two, one. In the video above, Dr Tia Kansara answers her own challenge without blinking: a spoonful of cold-pressed organic coconut oil. The practice is oil pulling, and as she explains, it is not a wellness trend but one of the oldest

A flower older than medicine itself now matches the antidepressants, the OCD drugs, and the stimulants in head-to-head trials — with fewer side effects, a lower price, and kinship with the human body How saffron challenges the antidepressants, the OCD drugs, and the stimulants — on efficacy, safety, accessibility, and price. For three thousand years, Crocus sativus — saffron — has been threaded into the food, ritual, and medicine of Persia, India, and the Mediterranean. What
