In this week’s nutrition headlines: A new (rather graphic) ad wants to keep you from pouring on the pounds, coffee and alcohol are linked to irregular heartbeats and there's a new "veggie-filled" Goldfish snack on the market.

This is a Time Magazine cover story you won’t want to miss -- especially if you’re a Michael Pollan fan or like to know where your food comes from. The piece goes into hidden food costs, who is footing the bill and why some of our food is so cheap, both in price and quality. Interesting stuff!

Occasionally, I buy the baked Goldfish snacks for my kids. Pepperidge Farm just debuted a new product, Goldfish Garden Cheddar snack crackers. I haven't seen or tried them myself yet, but according to the company, these new fishies offer a one-third serving of real veggies and no trans fats. Wait, what? How can “real” veggies come from a packaged snack? Has anybody given these a try? I would love to hear about it.

Alcohol and Caffeine Linked to Increased Heartbeat

Speaking of popular beverages, if you drink more than 10 alcoholic drinks a week or four cups of coffee a day, you better watch out. A newly released British study concluded that having that much (or more) can increase your risk of an irregular heartbeat. The study followed a good number of British men and women (8,830 to be exact) and those that did down alcohol and coffee at those rates had a 80% higher chance of heart problems. What’s considered an "alcoholic drink"? A standard 5-ounce glass of wine, 1.5 ounces of 80-proof liquor or 12 ounces of beer.

Football season is just around the corner, and you might be prepping your tailgating menu. Consider taking a page from Tony Gonzalez's cookbook. The tight end has been following a mostly vegetarian diet for the last three years, which he credits for helping stay in shape. Of course, he does admit to eating organic chicken and fish once in a while, but it’s better than his previous diet of fast food, TV dinners, potato chips and soda!
