High in monounsaturated fats - good for your heart and arteries, especially for diabetics.
Copper content helps iron utilization, energy production and antioxidant defenses, elimination of free radicals, development of bone and connective tissue, and the production of the skin and hair pigment called melanin. 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.
Numerous health problems can develop when copper intake is inadequate, including iron deficiency anemia, ruptured blood vessels, osteoporosis, joint problems such as rheumatoid arthritis, brain disturbances, elevated LDL (bad) cholesterol and reduced HDL (good) cholesterol levels, irregular heartbeat, and increased susceptibility to infections.
Magnesium 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 stored on the surface of the bone 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 contributes 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. 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.
