Dr. Oz: Supermarket secrets, anti-aging creams and weight loss snacks

Dr. Mehmet Oz revealed the dirty little secrets supermarkets are hiding on the Feb. 21 episode of the Dr. Oz Show ("The Cringeworthy Truth About the Supermarket").

Dr. Oz said many supermarkets are breeding grounds for bacteria due to poor food handling and unsanitary conditions. Dr. Oz's guest was Councilman Peter DeLucia, a health commissioner in Westchester County, N.Y.

DeLucia said most supermarket shopping carts are dirtier than a public toilet, with most of the germs collecting on the handle and the seat where children usually sit. Studies found germs and even fecal matter in these areas.

The best way to protect yourself is to wipe the cart down with an antibacterial wipe and use a shopping cart cover for small children.

Another shocking secret is that a lot of the beef you see at supermarkets is older than it looks, making you vulnerable to pathogens like salmonella, E. coli, and staph. Supermarkets use a practice called atmospheric packaging, which injects carbon dioxide into the packaging, preserving the beef's red color (which makes it look fresher than it really is).

To avoid getting sick from old meat, Dr. Oz said to pay close attention to the expiration dates and to avoid buying beef that looks discolored, brownish, or just otherwise odd.

Dr. Oz said many supermarket vegetables and fruits — especially lemons and limes — are contaminated with bacteria and fecal matter, so you should wash them as soon as you get home, preferably in a solution of vinegar and water.

Finally, DeLucia said many supermarkets don't properly store eggs. When buying eggs, don't buy carton above the "cold line," where temperatures are too high to ensure freshness.

Anti-Aging Wrinkle Products Turn Back the Clock

In a separate segment of the show, Dr. Oz revealed how you can smooth wrinkles and get rid of age spots using inexpensive anti-aging creams and serums.

Dr. Oz's guests were dermatologists Dr. Dennis Gross and Dr. Hilary Reich, who recommended the following treatments:

  • Vitamin C serum for wrinkles. Dr Reich said topical vitamin C serums have antioxidants that promote collagen growth and diminish wrinkles.
  • Alpha hydroxy acid peel for brown patches and age spots. Dr. Gross, who has his own skincare line, said these peels exfoliate skin and minimize age spots.
  • Peptide cream for sagging skin. Dr. Gross said peptides increase collagen and elastin production to reduce the appearance of sagging.

Dr.'s Fat-Burning Snacks For Diabetes Management and Weight Loss

Dr. Oz said the following snacks accelerate weight loss, curb hunger, and block fat:

  • Figs. Dr. Oz said figs are high in fiber and suppress appetite. They're also rich in potassium, have anti-aging omega-3 fatty acids and antioxidants, and have been shown to help improve skin elasticity.
  • Fenugreek. Fenugreek is an antioxidant-rich Egyptian plant that lowers blood sugar. Fenugreek is great for managing diabetes, as it slows down carb digestion, preventing insulin and blood-sugar spikes.
  • Watermelon. Watermelon is high in fiber and has metabolism-boosting amino acids. Plus, it tastes great and is very filling.
  • Licorice root. Licorice root (not the candy) has an enzyme that blocks fat and prevents hunger. It has been hailed for its weight-loss benefits because it dramatically curbs sugar cravings.
  • Pistachios. Pistachios are high in protein and have fewer calories than other nuts. Nuts in general have been shown to boost weight loss and longevity.
  • Pine nuts. Pine nuts are rich in polyunsaturated fats and helps you burn more calories. They also add a nice crunchy texture when sprinkled on top of soups and salads. Dr. Oz recommends consuming two tablespoons three times a week.
