Are There Carcinogens in Roasted Nuts?

Concerns about carcinogens in roasted nuts centers on acrylamide, a compound formed when certain plant foods are cooked at temperatures above 250 degrees, especially by frying, baking, broiling or roasting for long cooking times. Cooking causes a chemical reaction between sugars in the food and an amino acid called asparagine, which in turn forms acrylamide. Among the foods most noted for producing acrylamide are potatoes, leading to concerns about French fries and potato chips.

Cutting Away Mold on Fruit: Is it Safe?

Molds are microscopic fungi that live on plant or animal matter, which can sometimes be seen with the naked eye. These organisms give off spores, which are responsible for their color. While many molds are harmless and beneficial, such as cheese, some molds cause allergic reactions and respiratory problems. Similarly, a few molds, under the right conditions, produce mycotoxins-poisonous substances that can make you sick. In many foods, mold invades deep within the food-not just on the surface. In some cases, toxins may have spread throughout the food.
