Macadamia nuts originated in Australia and then spread from Latin America to Africa and Asia. Recently, Hawaii is the commercial producer of these nuts while its trees are also found in California and Florida. These are best grown in tropical climates and especially on volcanic soil.
Macadamias can be eaten raw from the shell, drily roasted, or cooked in oil. These nuts are also used in the food products like sauces, cakes, confectionery, ice cream, and casseroles; but due to there high-calorie content, can be used only as the substitute for sources of saturated fats in the diet. An average such nut contains 18 calories hence keep an eye on the quantity of its consumption if you are on a low-calorie diet. Adding macadamia nuts on top of a normal diet would only add extra calories and can potentially reverse its benefits.
Over the years, these nuts have been loved for their flavor but avoided because of their fat content. These nuts are also very good for the health of those who are following a low-carbohydrate diet.
Nuts are a rich source of fat, which is generally unhealthy for people suffering from bad cholesterol levels; however, it all depends on the type of fat a nut contains. Macadamia nuts contain a high level of monounsaturated fatty acids like olives but many studies show that monounsaturated fatty acids are very helpful to reduce blood cholesterol levels. Despite this fact that macadamia nuts contain high levels of monounsaturated fatty acids, it would be surprising that these nuts like all non-animals food contain no cholesterol which surely helps in minimizing blood cholesterol levels. It seems that if you particularly want to reduce blood cholesterol levels then adding these nuts to your daily diet may prove to be a good addition.
Oil of macadamia nuts is also used in cosmetic industry because it helps healthy cell formation in the development of both internal tissues and skin.
Research suggests that these nuts are an organic resource of protein, fiber, and energy. As part of a balanced diet, they can also help control your weight by satisfying your hunger for a longer period of time. Dietary fiber helps by promoting slow digestion, reducing hunger, desirable intestinal bacteria and also relieves constipation. Macadamias are lower in protein than other nut snacks but have the ability to add more protein to meals such as salads that lack amino acid content. Protein helps in muscle function and maintenance.
Macadamia nuts contain antioxidants (vitamin A and vitamin E) which help to remove free radicals from the body. Vitamin A, which is an important eye vitamin, helps to prevent cataracts and other eye diseases of a similar kind. Vitamin E prevents a heart attack by protecting the arteries from damages and also reduces chances of other heart diseases.
Macadamias are a good source of a range of minerals naming Iron, Potassium, Phosphorus, Magnesium, and Calcium. They also contain significant levels of Zinc, Copper, and Selenium with very low Sodium. Potassium helps improve low blood sugar condition, supports kidneys, avoids heart problems, boosts muscle strength, enhances brain function and improves metabolism. Another function of Potassium found in these nuts is regulating the nervous system and water retention in your body. Researchers also found an abundant source of manganese in macadamia nuts. This important mineral is largely involved in the metabolic functions and the healthy formation of bones.
