Pecans are considered to be the only nut tree that grows naturally in North America and is also considered to be the most valuable nut species in the same region. Pecan is a native American word given to all the nuts that are generally thought to crack with help of a stone (or tools producing similar force). While pecans were readily available in America and Mexico, many native tribes used pecans as their major source of food during the autumn season.
Pecans are sold in markets in a variety of sizes (extra large, large, medium, and small) and in different forms (classified mainly as wholes, halves, pieces, granules and in some cases as a meal item).

Antioxidants are counted as important nutrients in food and especially in nuts as these help providing protection from cell damage, help fight cancer and may prevent from neurological diseases like Alzheimer.
Pecans have fats which are approximately 60 percent monounsaturated and about 30 percent polyunsaturated, meaning that saturated fats are present only in a very little amount. The unsaturated fat in these nuts is healthy for our heart and is treated as a fat produced from healthy sources (mainly fish, nuts and vegetable oils).
Pecans are also very helpful to maintain lower and healthy cholesterol levels in our body. Research works performed on individuals with high level of cholesterol, where they were provided a pecan enriched diet, showed that eating such enriched diet controlled and lowered the total cholesterol in body significantly and without any weight gain. Research also established that these nuts contain plant sterols which are famous for lowering cholesterol levels in our body. Scientific and medical evidences suggest that eating a balanced quantity of most nuts like pecans as a diet in combination with low saturated fats and low cholesterol may prove to be very useful in reducing the risks of heart attacks and similar diseases.
Pecans nuts may also help in achieving weight loss and maintaining the results for long term as nuts consumption may boost our metabolism rates.
