據營養學研究，核桃除去約50 %的殼等廢棄物後的淨仁，含有63 %的亞油酸，16.4 %的亞麻酸，以及豐富的蛋白質、磷、鈣和維生素A等物質。因其含高量的不飽和脂肪酸，能強化腦血管彈力和促進神經細胞的活力，故具備多種健腦食品的優點。
The walnut is a fruit which resembles a green peach. When it is fresh, the external shell is green and smooth. As the fruit dries up, the shell comes off naturally to reveal the walnut that we typically see in markets. The walnut is very hard with an uneven surface, but the kernel contains a high amount of oil, is edible and can be added to tonics. The wood of the walnut tree can be made into utensils.
In the Compendium of Materia Medica, it is recorded: “Eating walnuts can make one plump and healthy, lubricate the muscles and make hair and beard black. Eating them frequently benefits the urinary system, and eradicates the five hemorrhoids. It also has the general purpose of improving the circulatory flow, remedying the lack of energy and nourishing the blood, improving the moisture content of the spleen and the intestines, and can cure chills, asthma and recurring pain in the waist and legs.” Walnuts should not be eaten all at once, but should be consumed gradually over a period of time. One walnut should be eaten on the first day, and this number is increased by one every five days until the maximum number of twenty walnuts is reached. Then the cycle is repeated starting from one walnut all over again. Consuming walnuts on a regular basis improves the appetite, makes the bones and flesh subtly oily, shiny and moist, the hair and beard black and glossy, and improves the blood flow. (Excerpt from Compendium of Materia Medica by Li Shizhen).
Every 100g of walnut contains 63g fats, 15.4g protein, 119mg calcium, 362mg phosphorus, 3.5mg iron, carotene, and vitamins B1, B2, etc., and can produce 669 kilocalories of energy. Like the red date and the longan, it is a highly nutritious food. (Excerpt from the website – “Eating walnuts nourishes the brain”).
According to an article published on June 13th in the newspaper Da Ji Yuan Shi [Great Era Times], nutritional research has shown that the clean kernel of the walnut, after 50% of the external shell and other unwanted parts have been removed, contains 63% flax seed oil and 16.4% flax seed acid, and is a rich source of protein, phosphorus, calcium, vitamin A, etc. Because it is high in unsaturated fats, it can increase the elasticity of the blood vessels in the brain and stimulate brain cell activity. Hence it has the good qualities of many brain-nourishing foods.
As early as the Sui and Tang dynasties, when the system of imperial examinations flourished, the examinations to select government officials were complicated and stringent. Candidates sitting for examinations then ate walnuts to nourish the brain. In Japan, a nutritionist by the name of Sezuo Ii No strongly advocated that school-age children eat 2 to 3 walnuts a day. It can restore the mental abilities of those who are restless, poor in energy, dislike studying, or having slower responses. This proposal has already gained the acceptance of many parents. In Chinese medicine, the walnut is regarded as pleasant and mild, and is most suitable for nourishing the kidneys and boosting energy. When the essential energy of the kidneys is full, it aids the healthy development of brain activity. It's no wonder that the treatise of Chinese medicine, “Revealing the Treasure Trove of Native Herbs,” states that the walnut can nourish the brain, lubricate the muscles, cause the hair to be black, and one to be plump and healthy.

The Organic Walnut Ranch of the City of Ten Thousand Buddhas
The organic walnut ranch is about a twenty-minute drive from the City of Ten Thousand Buddhas. It occupies an area of over 60 acres and has over a thousand walnut trees, each about 20 feet tall. The walnuts produced by these trees have a sweet and fragrant flavor beyond compare. Ever since the City of the Ten Thousand Buddhas purchased this piece of land twenty-five years ago, it has never been fertilized or watered. The walnuts grown there are purely products of nature and were certified in 2002 by the relevant authorities of the American government as organically grown agricultural products. Most walnut ranches use chemical fertilizers or olfactory repellants to drive out squirrels that feed on the nuts and spoil or reduce the harvest. The City of Ten Thousand Buddhas, however, wraps aluminum foil around the tree trunks making it difficult for squirrels to climb the trees. The sight of the shimmering silvery foil tucked between the rows of lush walnut trees is a pretty one, and is one of the main attractions of the ranch. But a quarter of the trees at the ranch have not been wrapped with foil, perhaps to leave some food for the squirrels? Who knows?
In addition, at the back of the City of Ten Thousand Buddhas, there is another walnut grove of about 10 acres with about 100 trees, each about 10 feet tall. Within the City itself there are also several walnut trees. Every year at harvest time, one sees the residents of the City of Ten Thousand Buddhas decked out in straw hats and protective kneepads and carrying huge sacks or plastic pails, walking to the walnut grove to harvest. In the cool weather of autumn, amidst the vast expanse of land, taking off half a day to work together brings pleasure without end. The walnuts harvested are then peeled of their skins, shelled and hand-picked using a sieve before being placed in packets. The walnuts are naturally fresh and sweet as well as being highly nutritious.
(A crop is said to be organic if grown on land free from pesticides and chemical fertilizers, using only organic compost that has been thoroughly decomposed. [For example, wood shavings, fruit peels, roots, etc. which have been fermented and thoroughly decomposed can be used as fertilizers.] Organic farming methods do not destroy the natural ecology, but allow crops to grow and mature at their natural rate.)
Organic foods often contain high amounts of trace elements and vitamins, which absorb activated enzymes and retain the natural flavor of fruits and vegetables. They can be kept for long periods of time after being harvested, and they improve health and increase the body's immunity level.
