All About Vitamins & Minerals

We all know that vitamins and minerals are important, but why? Here’s what you need to know about what’s in your food… or your Flintstones chewables.

All About Gluten

Vague digestive complaints? Headaches and skin rashes? You may want to avoid that sandwich or plate of pasta. Why and how your daily bread may be making you ill.

All About Cholesterol

It’s often made out to be the bad guy in today’s medical world. But cholesterol is an important molecule in the body. With the right diet and exercise program, you can put the power of cholesterol to work for you. No appointments to see your doc required.

All About Recovery

You’ve probably heard of overtraining. In fact, it makes more sense to think about this phenomenon as “under-recovering”. Why you should make recovery protocols part of your overall training plan.

All About Lectins

Bean sprouts aren’t just for hippies. There’s method in that madness — reducing the harmful effects of lectins, substances found in many foods. If you’re experiencing GI distress, lectins may be the culprit. Read more about these ubiquitous substances, and how to control their effects.

All About Cancer and Nutrition

Cancer is a major cause of premature death. Yet cancer is treatable. Cancer is preventable. Good nutrition and avoidance of overweight are two of the most important strategies for keeping this killer from striking.

All About Glutamine

Should you supplement glutamine? Well, double check: are you lying in a hospital bed? Are you sitting at your Polish grandmother’s dinner table? In those cases, the answer may be yes. If not, you may want to save your money.

All About Vitamin D

Vitamin D, aka the “sunshine vitamin”, is crucially important for the body. And yet most of us are probably deficient. Grab the convertible or get on your bike and head to the beach!

All About Drinking Water

Sure, drinking water is good for you — water does a lot of important things for your body. But did you know that bottled water is over four times the price of gasoline? And that barely 1% of the world’s water is safe to drink? You might want to take a closer look at what’s coming out of the tap or bottle before you chug-a-lug.

All About Dietary Acids and Bases

Has anyone ever called you “unbalanced”? It might not refer to your mental state, but to your acid-base status. The foods we eat can affect our body’s pH levels, and if we consume too much of the wrong foods, our bodies have to work hard to keep things under control. Find out if you’re dropping too much acid.

All About Chocolate

Chocolate’s mysterious allure has lasted hundreds of years, from the ancient Mayans to the modern science of antioxidants. Where does chocolate come from? What makes it so appealing? And is it truly good for us?

All About Diabetes Mellitus

What if we told you that there was a disease that struck 7% of the US population (and nearly one-third of people in some areas)… a disease that led to a multitude of other common and serious diseases, disabilities, and premature deaths… and that about 85% of these disease cases were completely preventable? Read all about diabetes mellitus, and what YOU can do to cut your risk, right now.

All About Diet Sodas

Diet soda is a no brainer. We drink it to avoid the sugar calories from regular soda, right? But do the benefits of consuming fewer sugar calories outweigh the risks of consuming artificial ingredients?

All About Dehydration

Feeling thirsty? Maybe it was that soy-sauce-laden takeout. Maybe it was the four beers after the game with friends. Or maybe it was that jog in Death Valley. In any case, you’d better drink up — because dehydration can put a cramp in your athletic performance.

All About Flax

Flax, one of humanity’s oldest cultivated crops, offers several potential health benefits, particularly because of its fibre and omega-3 fatty acid content. Yet in many cases, the data are mixed; we’re still not completely sure which health conditions flax definitively prevents or treats. (You might say: Flax on? Flax off?)

All About Cardiovascular Disease and Nutrition

Poor nutrition can be a heart breaker, a love taker, and definitely not a dream maker, so don’t you mess around with CVD. (Apologies to Pat Benatar.)

All About Soy

From thyroid disease to GMOs, from breast cancer to infant formula, there’s been a lot of conflicting media reports on the safety of soy. We review the evidence, and explain the source of soy’s power as potential hero or villain.

All About Sleep

How can ZZ affect your BF? (And your GH, TSH, IR, GT, and T2D?)

All About Cortisol

Whether the economic crisis keeps you awake at night, whether you’re stressed out at work, or whether you’re just hitting the treadmill too often and for too long, you might be at risk for chronically elevated cortisol levels. Find out what cortisol is, how it works, and how it can affect your health, performance… and even that six-pack you covet.

All About Food Sensitivities

Gassy? Throat closing up? Sensation of digesting broken glass? It might not be just your spouse’s poor cooking skills; you could have a food sensitivity.

All About Intermittent Fasting

Benjamin Franklin was probably on to something with “Early to bed, early to rise, makes a man healthy, wealthy, and wise” but was he also right when he said, “The best of all medicines is resting and fasting”?

All About Alcoholic Beverages

Drink to your health? What you need to know about alcohol consumption and physical wellbeing.

All About Caffeine

There’s nothing like a good ol’ espresso buzz before a morning workout; after all, research shows that caffeine can improve your athletic performance temporarily. But is it GOOD for you? How does it work? We review the evidence.

All About Fructose

Afraid of apples? Petrified of pears? Don’t be — it’s not as scary as what may be lurking in your yogurt.

All About Bad Fats

What do margarine, Doritos, and kinky caterpillars have in common? Find out!

All About Nutrient Deficiencies

Cracked lips? Weird tingling? Scratchy eyeballs? Could be the morning after the night before, or it could be a nutrient deficiency.
