The Mayo Clinic conducted a study which found that all nuts are nutrient dense and naturally cholesterol free. Not only are nuts cholesterol free but, studies have suggested that eating pecans may help reduce LDL cholesterol levels, leading to a reduction in the risk of heart attacks and coronary artery disease.
Pecans are also a rich source of oleic acid, the same type of fatty acid found in olive oil. Researchers from Northwestern University in Chicago recently found in laboratory tests that oleic acid has the ability to suppress the activity of a gene in cells thought to trigger breast cancer.
Pecans are good for lowering cholesterol levels. The plant sterols in pecans help battle heart disease by lowering blood triglyceride and LDL cholesterol levels in the blood, helping to clear the arteries, while maintaining desirable levels of HDL ("good") cholesterol. The nutrients in pecans: zinc helps guard against infections, vitamin E protects against cancer, and vitamin A helps keep your complexion clear.
More recent research confirms that pecans can prevent or delay the onset of motor neuron degeneration including Lou Gehrig’s Disease, Alzheimer’s, Parkinson’s, cancer and heart disease.
