smoke

With Summer grilling in full force and smoke-tinged cocktails taking the helm at bars nationwide, the food world has been singing the virtues of liquid smoke. But what is this mysterious substance, and how does it obtain its trademark taste?

A concentrated flavoring used to duplicate the essence of smoked wood, liquid smoke is literally the flavor of smoke captured in water. Wood chips or sawdust are burned in a controlled environment, producing tiny smoke particles held in water vapor. Chilled air is introduced, causing the particles to condense into liquid. The liquid is then aged in oak barrels.

Liquid smoke is usually made from smoked hickory, mesquite, pecan, or apple wood, and can be applied to a gas grill to add a charcoal flavor, added to a meat marinade or curing solution, or used on soft cheeses and meatless proteins such as tempeh.

I was out with some friends who were celebrating their engagement, and one of the guys pulled out some cigars. He offered one to me and I gave him this look like "Are you serious?" and he said, "Cigars aren't bad for you because you don't even inhale."

When you smoke a cigar, you're only supposed to suck the smoke into your mouth then blow the smoke out. So does that means it's any better for you than cigarettes?

It's still a tobacco product like cigarettes, right, so I think you know what the answer is. Large cigars typically contain between 5 and 17 grams of tobacco. Some premium brands have as much tobacco in 1 cigar as in a whole pack of cigarettes!

Plus, the tobacco in cigars is different than what's found in cigarettes. It's fermented tobacco, so it has a high concentration of nitrogen compounds. When smoked, these compounds give off several tobacco-specific nitrosamines (TSNAs), some of the most potent human carcinogens known. Also, because the cigar wrapper is less porous than cigarette paper, the tobacco doesn't burn as completely. The result is a higher concentration of nitrogen oxides, ammonia, carbon monoxide, and tar -- all very harmful substances.

I think sweet potatoes have gotten a bad rap because of their high carb content. They shouldn't be overlooked because they are one of the most nutritious foods you can eat. Not only that, they are a great option if you're craving something sweet.

Want to know why they're so good for you?

• They're bursting with healing antioxidants due to their high levels of vitamins A and C. Antioxidants work in your body to help eliminate free radicals which are the chemicals that damage cells and are associated with the development of conditions like colon cancer. These vitamins are also anti-inflammatory, so they can help reduce the severity of certain conditions like asthma and arthritis.
• They're low in calories and have no fat.
• They are labeled as a low-glycemic index food, by virtue of their slow digestion and absorption, produce gradual rises in blood sugar and insulin levels, and have proven benefits for health.
• They are also high in vitamin B6, manganese, copper, potassium, and iron.
• Eating sweet potatoes with their high vitamin A content may help save your life if you or someone you love is a smoker. A common carcinogen in second-hand smoke known as benzopyrene induces vitamin A deficiency. If you aren't getting enough of this vitamin, you could increase your chances of developing emphysema. A diet rich in vitamin A can help prevent it.

Fit's Tips: When you go to a restaurant, choosing sweet potato fries is a healthier choice than regular French fries, but they're still deep-fried. To get your fill of the nutritious goodness in sweet potatoes, bake them whole (don't cut or poke them) in the oven at 400 for 40 minutes to an hour. If you love the fry idea, but don't want all the fat, just cut them up (leave the skins on), drizzle a little olive oil over them, and bake in a pan. Mmmmmm.
