Cashews are a very good source of monounsaturated fats and copper, and a good source of magnesium, manganese, and phosphorus.

1. Not only do cashews have a lower fat content than most other nuts, approximately 75% of their fat is unsaturated fatty acids, plus about 75% of this unsaturated fatty acid content is oleic acid, the same heart-healthy monounsaturated fat found in olive oil. 


2. An essential component of many enzymes, copper plays a role in a wide range of physiological processes including iron utilization, elimination of free radicals, development of bone and connective tissue, and the production of the skin and hair pigment called melanin. For example, copper is an essential component of the enzyme, superoxide dismutase, which is important in energy production and antioxidant defenses. Copper is also necessary for the activity of lysyl oxidase, an enzyme involved in cross-linking collagen and elastin, both of which provide the ground substance and flexibility in blood vessels, bones and joints. Low dietary intake of copper may also be associated with increased fecal free radical production and fecal water alkaline phosphatase activity, risk factors for colon cancer.


3. Everyone knows that calcium is necessary for strong bones, butmagnesium is also vital for healthy bones. About two-thirds of the magnesium in the human body is found in our bones. Some helps give bones their physical structure, while the rest is found on the surface of the bone where it is stored for the body to draw upon as needed.

Magnesium, by balancing calcium, helps regulate nerve and muscle tone. In many nerve cells, magnesium serves as Nature's own calcium channel blocker, preventing calcium from rushing into the nerve cell and activating the nerve. By blocking calcium's entry, magnesium keeps our nerves (and the blood vessels and muscles they ennervate) relaxed. If our diet provides us with too little magnesium, however, calcium can gain free entry, and the nerve cell can become overactivated, sending too many messages and causing excessive contraction.

Insufficient magnesium can thus contribute to high blood pressure, muscle spasms (including spasms of the heart muscle or the spasms of the airways symptomatic of asthma), and migraine headaches, as well as muscle cramps, tension, soreness and fatigue. Given these effects, it is not surprising that studies have shown magnesium helps reduce the frequency of migraine attacks, lowers blood pressure, helps prevent heart attacks, promotes normal sleep patterns in women suffering from menopausal sleep disturbances, and reduces the severity of asthma. Just a quarter-cup of cashews provides 25% of the daily value for magnesium.

4. wenty years of dietary data collected on 80,000 women from the Nurses' Health Study shows that women who eat least 1 ounce of nuts, peanuts or peanut butter each week have a 25% lower risk of developing gallstones. Since 1 ounce is only 28.6 nuts or about 2 tablespoons of nut butter, preventing gallbladder disease may be as easy as packing one cashew butter and jelly sandwich (be sure to use whole wheat bread for its fiber, vitamins and minerals) for lunch each week, having a handful of cashews as an afternoon pick me up, or tossing some cashews on your oatmeal or salad.

5. Although nuts are known to provide a variety of cardio-protective benefits, many avoid them for fear of weight gain. A prospective study published in the journal Obesity shows such fears are groundless. In fact, people who eat nuts at least twice a week are much less likely to gain weight than those who almost never eat nuts.

A Few Quick Serving Ideas:

Combining cashews with other nuts and dried fruits makes a healthy snack.
Right before taking off the heat, add cashews to healthy sautéed vegetables.
Healthy sauté cashews with shrimp, basil and green beans for a delightful Thai inspired dish.
Cashews with a little bit of maple syrup make a great topping for hot cereals.
Add cashew butter to breakfast soy or rice milk shakes to up their protein content (a quarter-cup of cashews provides over 5 grams of protein) and give them a creamy nutty taste.
In a saucepan over low-medium heat, mix cashew butter with some tamari, cayenne pepper, garlic, ginger and water to make a wonderful sauce for fish, vegetables, tofu or rice.
To roast cashews at home, do so gently--in a 160-170°F (about 75°C) oven for 15-20 minutes--to preserve the healthy oils.
