　　Mountain pig meat is delicious and nutritious, making it a premium type of game meat. Compared to domestic pigs, it has higher protein content, primarily in the form of crude protein, more calories, lower fat content, and especially a leaner meat profile. Its cholesterol content is 29% lower than that of domestic pigs, and it contains various trace elements and amino acids. The linoleic acid content—essential for humans—is 2.5 times higher than that in domestic pig meat, meeting the nutritional needs of modern diets. It is a high-quality health and beauty meat. Wild boar meat has a strong game flavor and comprehensive nutrition, providing body-strengthening and nourishing benefits. Domesticated wild boars retain their original appearance and physique, along with strong disease resistance, tolerance to coarse feed, and good gregariousness. Their breeding process avoids artificial feed additives and growth promoters. Being hormone-free and drug-free, it is considered “reassuring meat” and “green meat” in the “vegetable basket,” thus highly favored by people.

　　Mountain pig meat is an excellent health food for nourishing the body, containing 17 essential amino acids required by humans. It is high in linoleic and linolenic acids, which help lower blood lipids and are beneficial in preventing coronary heart disease and cerebrovascular sclerosis caused by arteriosclerosis. It also shows significant efficacy in treating human intestinal bleeding. Linoleic acid promotes the absorption of fat-soluble vitamins and reduces cholesterol deposition in blood vessel walls. Additionally, it has anticoagulant, anti-thrombotic, and anti-cellular oxidation effects. Therefore, regularly consuming wild pig meat with high linoleic acid content can effectively suppress high blood lipids, high blood pressure, and arteriosclerosis. Teenagers who consume mountain pig meat often can enhance their explosive power and endurance.
