5-lipoxygenase (5-LOX) is a member of the lipoxygenase family of enzymes. It transforms fatty acids into leukotrienes. Excess levels of the enzyme 5-LOX sets in motion inflammatory responses that have been linked to common effects in aging individuals. Normal aging results in higher-than-desired levels of 5-LOX. The typical American diet adds to the danger. Foods rich in omega-6 fatty acids like red meat, poultry, eggs and dairy products, along with high-glycemic carbohydrates, trigger overproduction of arachidonic acid. In response to high levels of arachidonic acid, the body produces the 5-LOX enzyme.
