Hold the acrylamide, pease!



Here's just one more reason America's vegetable of choice (in the form of chips or fries) needs a closer look.

In addition to the excessive fat and sodium content of potato chips and french fries, a chemical called arcylamide is also found -- a possible cancer-causing agent. Because acrylamide is found in carbohydrate foods which are cooked at high temperatures, acrylamide is also found in foods such as cereals, baby foods, breads, and crackers [1].

In lab animals, acrylamide is shown to cause tumors and neurological problems. Consumer's in the US are not seemingly phased by the recent discovery of the possible carcinogenic effects of acrylamide. Many


American's are yet to hear about acrylamide despite its presence in nearly 40% of foods. Federal governing bodies in the US, Canada, and Europe are stepping up efforts to reduce the levels of acrylamide in foods [1].

Acrylamide forms when sugars and asparagine (an amino acid) are heated together at temperatures more than 248 degrees Fahrenheit. This effect, which is partly a "Maillard reaction," enhances a food's color, texture, aroma, and flavor [1].


What to do about it? Continue eating a healthy, balanced diet that is low in fat, cholesterol, salt, and added sugar and rich in high-fiber grains, fruits, and vegetables, says the Food and Drug Administration. Joe Schwarcz points out that there is acrylamide in certain foods just like there are aflatoxins in peanuts, ethanol in wine, urethane in sherry, styrene in cinnamon, and hetreocyclic aromatic amines in beef bouillon [1].

It's also important to know that acrylamide levels vary greatly between identical products such as Krispy Kreme donuts and McDonald's french fries.

Just like anything and everything else, watch it. No food should be over-consumed in the diet -- balance is always the goal.

Asparagus to the rescue!

The amino acids and minerals found in asparagus extract may alleviate the symptoms of an alcohol hangover and also protect the liver cells against toxins according to a new study performed by the Institute of Food Technologists and published in the Journal of Food Science [1].

Asparagus has been used throughout history as an herbal medicine known for it's anticancer, antifungal, and anti-inflammatory effects, as well as it's diuretic properties. It should be noted, however, that the amino acid and mineral concentrations were highest in the leaves of asparagus, and not the shoots [1].

Oxidative stress caused from chronic alcohol use can stress the lover and create unpleasant side effects such as a "hangover". It was found that asparagus leaves did, however, alleviate cellular toxicities and thus decrease the physical ill-effects of excess alcohol consumption. This is not only important for hangover relief, but also in the protection of liver cells in the body [1].

While asparagus isn't what most hungover individuals gravitate to in the morning, it's interesting none-the-less. Now, where can I find some asparagus leaves? Kidding, kidding. This thing called a job keeps my love of wine in check!
