# Macadamia Nuts :
Benefits / Side Effects / Nutrition and Facts
* Macadamia nuts are rich, flavorful nuts native to the continent of
The macadamia genus includes eight species, two of which produce nuts which are a viable food source. John Macadam was the first to describe the genus, and by scientific convention, it was named for him. This genus of flowering trees is found in the family Proteaceae, and most of them actually produce poisonous or inedible nuts. Macadamia trees with food value have been cultivated for over one hundred years, and several farmers have produced distinct cultivars with unique traits such as particularly large or flavorful nuts.
Aboriginal Australians made macadamia nuts an important part of their diets, since the nuts are high in protein, along with an assortment of vitamins and minerals. Early explorers in the region were introduced to the nuts, which they called
The nuts grow in extremely hard kernels which are very difficult to crack open. This is one of the reasons why macadamia nuts are so costly, since they are challenging to shell. Once cracked, the shell reveals an ivory colored kernel which is rich in oil with a buttery, creamy flavor. The nuts may be eaten out of hand, roasted, or ground into nut butter. Many people pair macadamia nuts with white chocolate in confections, and they can also be found in nut mixes and other desserts.
Because macadamia nuts are so high in fat, you should refrigerate them for the longest shelf life. If kept at room temperature, the nuts may go rancid. Try to use macadamia nuts quickly in either case, as they generally taste better fresh. Toasting also highlights their flavor; to toast macadamia nuts, either roast them in a heavy pan or bake them, turning them occasionally until they turn golden brown.
* Macadamia Nuts Nutrition
Considered to be the world's most delicious nuts, macadamia nuts are small, crispy buttery flavored nuts loved by many of us. They are nuts from the macadamia trees, which are cultivated in tropical climates and in soil rich in minerals like potassium and phosphorus. Apart from being delicious, these nuts are good sources of protein and minerals and are considered to be an essential nutritional component in many diets and recipes. These nuts are sweeter and larger than many nuts and can be eaten either raw from the shell, dry roasted or cooked in oil. Macadamia nuts are a high energy food, commonly used in preparations of cakes, confectionery, ice cream, salads, roasts and casseroles to enhance the savor.

* Macadamia Nuts Health Benefits
= Fats : Macadamia nuts comprise 84% monounsaturated, 3.5% polyunsaturated and 12.5% saturated fatty acids. Being low in cholesterol and high in monounsaturated fatty acids which are "good" fats, macadamia nuts help in the body's manufacture of essential fatty acids by maintaining the balance between omega 6 and omega 3 fatty acids as well as increase the production of protective high density lipoproteins while suppressing the unhealthy low density lipoproteins. Hence, one of the most important macadamia nut health benefits is that being low in saturated fats and cholesterol, these nuts reduce the risks of heart diseases, stroke, anti-inflammatory diseases, anti-aggregatory diseases and immunomodulating diseases.
= Protein : Macadamia nuts are also rich in essential and non essential amino acids which play an important role in the body's muscle formation, connective tissues and blood plasma development and overall well-being.
= Carbohydrates : Carbohydrates, also described as dietary fiber are the most basic source of energy in our body. In their most simplest form, they are present as saccharides (sugar) in the body. Hence, these nutritional nuts are also a good source of sugars, sucrose, fructose, glucose and maltose, and some other starch-based material.
= Minerals and Vitamins : Macadamia nuts are loaded with vitamins like vitamin E, thiamine (B1), riboflavin (B2), niacin, pantothenic acid (B5) and folate, and minerals such as potassium, phosphorus, magnesium and calcium. Hence, the nuts promote healthy bone and teeth formation, as well regulate the body's fluid balance and immune system. Also they enhance our nervous system and promotes healthy skin.
= Dietary Fiber : Dietary fibers are nothing but roughage or complex carbohydrates that give a feeling of fullness and reduce appetite. Hence, macadamia nuts are rich in complex carbohydrates like lignans, hemicellulose, amylopectins, mucilage, gums and insoluble cellulose which promote desirable intestinal bacteria, slow digestion, and reduce constipation, hunger pangs, irritable bowel syndrome and other digestive problems.
= Phytonutrients ;
a substance found in certain plants which is believed to be beneficial to human health and help prevent various diseases.]
[ ^^파이토뉴트리언트 phytonutrient 란 Phyto(Plant：식물)와 Nutrient(영양소)의 합성어 이다.
즉 식물만이 가지고 있는 영양소 라는 뜻이다.
식물성 생리활성물질 이라고도 부르는데, 건강을 유지하고 질병에 대한 자연 방어력을 부여하는 예방의학적 영양소 이다.
식물이 종자보호를 위해 열매의 껍질부분에 만드는 천연 보호물질로서, 과일의 경우 외부 공격에 노출돼 있는 과일 껍질에 이 물질이 많이 들어 있어 다른 물질의 공격을 막는 한편 과육이 잘 영글도록 지켜준다.
포도 껍질의 안토시아닌, 당근의 카로틴 등이 모두 파이토뉴트리언트의 한 종류로 이들 물질은 곤충과 박테리아, 바이러스 등의 공격을 막아내며 생장을 유지시켜 준다.
사람이나 동물이 파이토뉴트리언트를 섭취하면 암이나 심장병 등을 예방할 수 있고 노화를 억제하는 면역 물질로도 활용된다. 최근에 파이토뉴트리언트가 인체 내에서 항암작용, 질병에 대한 저항력 증대에 효과가 있음이 입증되었다.
Phytonutrients 원문 계속
Macadamia nuts are good source of phytonutrients or phytochemicals[식물화학물질] like tocopherols[토코페롤 (비타민 E 의 본체)] and ^^tocotrienols[바로 밑에 해석 참조], (derivatives of Vitamin E), the biologically active components in the body that help remove free radicals which oxidize blood fats and damage healthy cells. Hence, their antioxidant properties reduce the possibilities of certain types of cancer like breast, cervical, gastrointestinal, lung, stomach and prostate cancer. Moreover, regular intake of the macadamia nuts serves in the growth of new tissues, slow down the aging process and also denigrates birth defects.
- ^^tocotrienol 토코트리에놀
비타민 E의 일종으로 벼의 미강과 팜 오일, 보리의 배아, 옥수수, 차즈기 등에 들어 있다. 항산화, 항암, 고지혈증 개선, 혈당 저하, 동맥경화 완화 등 다양한 생리활성을 가지고 있다.
알파, 베타, 감마, 델타(α, β, γ, δ) 4가지 형태가 있다. 토코페롤과 토코트리에놀 유도체들은 구조적으로 여러 가지 입체이성질체를 가지고 있으며 토코페롤과 토코트리에놀 두 종류의 화합물에 각각 네 종류의 동족체가 있어 모두 8종의 이성질체가 함께 존재하고 있을 때 비타민 E의 질병예방 효과가 가장 우수한 것으로 알려져 있다.
1990년대 중반 이후 항산화, 항암, 고지혈증 개선, 혈당 저하, 동맥경화 완화 등 다양한 생리활성 효과면에서 토코페롤보다 40~60배 정도 강한 것으로 알려져 의약품 및 건강보조식품의 소재로 개발되고 있다. 토코트리에놀은 벼의 미강과 팜 오일(palm oil), 보리의 배아, 옥수수, 차즈기 등에 들어 있다.
암세포의 확산을 방지하거나 사멸시키는 작용을 하며 산화로 인하여 일어나는 자유라디칼과 과산화 지방질의 생성으로 세포막과 세포 내 생체막의 생리 활성 상실, 세포기능의 약화 및 괴사 등을 억제하여 노화를 저지시키는 항산화 작용을 한다.
최근 연구결과에 따르면 알파-토코페롤만 섭취한 것보다 토코트리에놀의 이성질체가 함께 작용하면 시너지 효과를 나타내어 질병예방과 노화방지에 효과적인 것으로 보고되었으며, 알파토코트리에놀(α-tocotrienol)이 뇌졸중 또는 글루탐산염의 작용에 따른 뇌 기능의 퇴화로부터 뇌를 보호해 주는 것으로 보고되었다.
Macadamia nuts are safe as food, and they seem to be safe as medicine for most people. They can cause an allergy, but this is rare. Health care providers sometimes recommend macadamia nuts to promote digestion and relieve constipation, but eating too many of them may lead to constipation or diarrhea in some people.
In a preliminary study in which volunteers ate a diet containing large quantities of ground macadamia nuts for one month, researchers saw no negative side effects, and these results were similar to findings from an earlier study in which volunteers ate a diet containing large quantities of ground macadamia nuts for one month. Despite an increase in the proportion of fat in their diets, volunteers showed no significant change in weight or cholesterol levels. No negative side effects from eating the macadamia nuts were observed.
