  1. Omega-3 fatty acids can protect skin from UV rays

    Something fishy in skin protection

    It can protect the heart, brain, and even your gums. And now, here's one more trick fish oil can pull off: It can help prevent skin cancer by giving your immune system the power to fight the damage caused by UV rays.

    In a new study, 79 volunteers were given either 4 grams of omega-3 fatty acids or a placebo and then exposed to the equivalent of midday summer sun via a light machine that resembled UV rays.

    Fish oil actually doubled the level of immune system protection when compared to the placebo, according to the study in The American Journal of Clinical Nutrition.

    Of course, taking fish oil isn't license to spend a day roasting on the beach. In fact, that double protection was there after 8 minutes and 15 minutes of sun exposure -- but it was gone in 30 minutes.

    Yes, there are some things even omega-3 fatty acids can't do.

    That's why in addition to taking a quality omega-3 supplement each day, it's essential to take common-sense steps when it comes to sun safety.

    The best UV ray protection is shade, followed by a hat and clothing, especially clothing with built-in UV ray protection. But of course, many people want to go outside in a T-shirt, tank top, or swimsuit -- and in those cases, you'll want to use sunscreen.

    Don't get whatever's on sale, as many common sunscreens contain ingredients that are even more dangerous than too much sun exposure.

    Retinyl palmitate, a form of vitamin A commonly found in sunscreen, may actually cause cancer when exposed to sunlight. It's crazy to think that something this dangerous is actually used in sunscreen... but it is.

    In addition, avoid anything with oxybenzone, an endocrine-disrupting chemical linked to developmental and reproductive problems, organ toxicity, cellular damage, allergies, and more.

    And steer clear of anything that contains nanoparticles.

  2. Fast food industry and diabetes grow together

    We are what we eat

    Two recent studies caught my eye -- and while they're separate studies, they're directly related.

    The first finds that fast food industry now makes up more than 11 percent of the typical American's calories -- and nearly 15 percent of the calories consumed by young adults between the ages of 20 and 29.

    That's actually a slight drop from the numbers we saw earlier in the decade... but while the fast food industry will tell you that 10 or 15 percent shows it's a "moderate" habit, the second new study shows the truth: it's far too much.

    That's because this second study of diabetes and the fast food industry shows that 1 in 8 Americans have been diagnosed with diabetes. That's close to 30 million of us, and that number doesn't include the millions more who have the disease but haven't actually been handed a diagnoses yet.

    They'll find out soon enough.

    And even that number is just a drop in the bucket -- because an estimated 79 million Americans have pre-diabetes.

    That means more than a third of us have either diabetes or the condition that will eventually lead to the disease -- and if people continue to get between 10 and 15 percent of their calories from the fast food industry, that number will climb even higher.

    The refined carbohydrates, unhealthy fats, and processed foods in these meals will cause weight gain as well as metabolic changes, even with a so-called "moderate" intake of 10-15 percent.

    That, in turn, will lead to metabolic syndrome, prediabetes, and diabetes -- and even if you manage to avoid diabetes, you'll still be at risk for heart disease and more.

    There's one way to avoid it, and it's not to find some magic level of moderate junk food intake. It's to stick to a diet of healthy, fresh foods prepared from scratch at home and not by the fast food industry.

    I'll have more on diet this weekend -- including the one common-sense diet that can help prevent these diseases instead of causing them. And the best part of all? This diet is rich in a wide range of the foods you already love -- even chocolate.

    Yes, chocolate. But, sorry -- no fast food.

    Stay tuned!
