nutritive value
Macadamia nuts are considered one of the best table nuts in the world. They contain a high amount of oil and are therefore very fattening. Macadamia nuts are rich in nutrients, with an oil content of 70%-79%, especially rich in unsaturated fatty acids, mainly oleic acid and palmitic acid, the ratio of unsaturated fatty acids to saturated fatty acids in the kernel of the light shell species is 6.2, the ratio of coarse shell species is 4.8; protein 9%, but also rich in calcium, phosphorus, iron, vitamin B1, B2 and 8 kinds of essential amino acids.
Macadamia nuts are crispy and tender, with a unique creamy aroma, the world's best quality edible nuts, known as the "queen of dried fruits" and "the king of nuts in the world", the flavor and taste are far better than cashew nuts.
Medicinal value
1. Prevent atherosclerosis and cardiovascular disease
Atherosclerosis is one of the most common diseases in industrialized countries, and the occurrence of atherosclerosis is closely related to eating habits. Macadamia nut oil, a natural vegetable oil with a high content of monounsaturated fatty acids, not only does itself not contain cholesterol, but also reduces the amount of LDL cholesterol (bad cholesterol) in the blood, while maintaining or even increasing the content of HDL cholesterol (good cholesterol). This two-way modulation of killing two birds with one stone is not available in other fats. This is why macadamia nut oil can prevent heart disease.
Macadamia nut oil has been medically proven to be very effective in lowering blood pressure. In a 1996 study conducted abroad, 16 women with high blood pressure agreed to switch to macadamia nut oil for a month. As a result, their blood pressure dropped from an average of 161/94 to 151/85, and both diastolic and systolic blood pressure were reduced by almost 10 mm Hg.
Long-term consumption of macadamia nut oil, people's blood lipids will be controlled in a healthy state. Due to the biphasic regulatory effect of macadamia nut oil on blood lipids, it can effectively reduce blood viscosity, thereby preventing atherosclerosis, and can effectively protect the cardiovascular and cerebrovascular system. The latest research suggests that macadamia nut oil has the effect of preventing blood clots and controlling blood pressure.
2. Relieve diabetes
The monounsaturated fatty acids rich in macadamia nuts can lower blood pressure, regulate and control blood sugar levels, improve lipid metabolism in diabetics, and are the best source of fat supplements for diabetics. In addition, macadamia nuts are rich in antioxidants that can limit the peroxidation process in the body of diabetics.
3. Reduce the incidence of tumors and cancer
In people who regularly consume macadamia nut oil, the incidence of various cancers is very low, especially breast cancer and cancers of the gastrointestinal system, which are significantly lower than in other populations. The incidence of lung cancer in the Mediterranean region is 50% lower than in the United States due to the consumption of macadamia nut oil. Studies have found that macadamia nut oil can reduce the rate at which keto derivatives of carcinogens form tumors in the intestine. The protective effects of macadamia nut oil are related to its own abundance of monounsaturated fatty acids, antioxidants, and other trace elements. They work synergistically with each other and enhance the protective effect.
4. Prevent rheumatoid arthritis
Rheumatoid arthritis is a chronic inflammation of the joints of a chronic infection, and people who do not eat macadamia nut oil are 2.5 times more likely to develop rheumatoid arthritis than those who consume macadamia nut oil for a long time. At the same time, it was found that the rich vitamin E in macadamia nut oil can play a "beneficial role as a similar inhibitor." After the body consumes saturated fatty acids, they break down to produce hormones that promote inflammation; And when the body ingests the unsaturated fatty acids in macadamia nuts, they will break down to produce hormones that inhibit inflammation. Therefore, long-term consumption of macadamia nut oil can prevent rheumatoid arthritis.
5. Skin protects the skin
Among the many ingredients of macadamia nut oil, carotene and chlorophyll give macadamia oil a unique color of golden and translucent green, while chlorophyll plays a metabolic role, promotes cell growth, accelerates wound healing, and also helps nourish and beautify the skin, reducing the occurrence of wrinkles.
Macadamia nut oil is also an excellent natural remedy for skin ailments. According to the principle of dermatological topical treatment, 3 dosage forms made of macadamia nut oil have a significant effect on 15 types of exudative dermatitis and ulcers in 5 categories. Because macadamia nut oil contains polyphenols and lipopolysaccharides, macadamia nut oil also has radiation protection, so macadamia nuts are often used to make astronauts' food. Regular computer users regard it as a good product for health care and skin care.
6. Anti-aging
Aging is closely related to the peroxidation reaction in the human body, and human life is like a burning candle, the more intense the oxidation burns, the shorter the life span. Macadamia nut oil contains a large number of antioxidants, low saturated fatty acids, rich in a large number of monounsaturated fatty acids, polyunsaturated fatty acids are abundant but not excessive. At the same time, the ratio of essential fatty acids omega3 and omega6 is very ideal, when the ratio of essential fatty acids omega3 and omega6 is 1:4, it is difficult for various diseases to invade the human body. Osteoporosis is another serious problem prevalent in the elderly.
Macadamia nut oil has a very positive effect in preventing this disease. The more macadamia nut oil you ingest, the better the mineralization of the bones. The rich oleic acid contained in macadamia nut oil promotes the body's absorption of calcium, phosphorus, zinc and other minerals and improves bone density.
Remember to eat macadamia nuts often for good health.
