At the 2014 Winter Olympics in Sochi, Russia, it was unseasonably warm, and repeated losses by the favored Norwegian cross-country ski team prompted Norwegian newspapers to rant about smoerebom — loosely translated, it means "waxing failure."

It turns out that if you don't "grease the skids" just right for snow conditions (there are 500 waxing preparations to choose from), you can't glide to the gold.

But if you grease the skids for cancer cells, there's no gold for that. What you do get is a hugely increased risk for both aggressive prostate cancer and HER-2 negative, hormone-receptor positive breast cancer, as well cancers of the colon, rectum, kidney, and pancreas.

Fat in the diet and excess fat on the body both are cancer-promoting. Excess body weight contributes to as many as 20 percent of all cancer-related deaths. And even if you aren't overweight, a fatty belly is cancer-friendly.

A recent study found that men's risk for aggressive prostate cancer went up 13 percent for every 3.9-inch increase in waist size.

Here's how you win a gold medal for smart living.

Eliminate all trans fats (check ingredients lists for hydrogenated oils) and most saturated fats; stick with extra-virgin olive oil and foods rich in omega-3, such as salmon, flaxseed, walnuts, and walnut oil — even basil.

Add that to a Mediterranean mix of fresh fruits and veggies, and make animal protein a side dish, not an entrée.
