Dark chocolate containing more than 85% cacao is full of various nutrients such as fiber, iron, and magnesium. It is rich in antioxidant polyphenols, which inhibit free radicals that cause arteriosclerosis, cancer, and aging, purify blood, and lower blood pressure.

It also contains pectin, a vegetable fiber, which is good for constipation. Potatoes are considered one of the few “complete foods” because they contain most of the essential nutrients in small amounts. In fact, there are records of people who survived on only potatoes for a very long time.
Seaweeds called “vegetables of the sea” refer to seaweed, seaweed, and kelp. Seaweed is rich in minerals such as calcium, iron, magnesium, protein, and vitamins, which purify the blood and prevent anemia. It is also effective in preventing various adult diseases such as high blood pressure and arteriosclerosis and cancer. It contains a lot of iodine, a mineral component, which helps to prevent thyroid disorders and increase metabolism.
Garlic is an essential ingredient in Korean cooking. Garlic is loved as a spice because it improves the taste of food and has an appetite-stimulating effect.

In particular, salmon is rich in acid, protein, vitamins and minerals, which helps to optimize the body’s functions and is known to be effective in preventing heart-related diseases, dementia, and depression. The American Heart Association recommends eating fatty fish, such as salmon, twice a week.
6. Egg Yolk
Egg yolks were considered a avoidable food because of their high cholesterol content. However, a recent study found that egg yolks only increase good cholesterol. Although high in cholesterol, it does not affect the level of low-density lipoprotein (LDL), which is bad cholesterol in the body. Egg yolk contains nutrients that are hard to find in other foods, especially vitamin D and choline, and is rich in lutein and control xanthin, so it is an effective drug for preventing eye diseases. Because it is a high-protein food, it is helpful in dieting.

Kale is also good for cancer prevention. In particular, it is effective in suppressing breast, rectal, and cervical cancer. It also contains 10 times more rutin and zeaxanthin, which protect the eyes, so kale is recommended for eye protection.

Animal liver is a low-fat, high-protein food rich in nutrients. It promotes metabolism and improves physical strength, and iron and folic acid in the liver are known to be good for anemia. In addition, animal liver is in the spotlight as a health food because it functions to store essential nutrients in our body for a longer period of time.

The most representatively known function is the effect of improving eyesight. The anthocyanin pigment contained in blueberries prevents cataracts and retinitis by preventing protein aging in the eyes. In addition, it is known to have effects such as capillary protection, prevention of scurvy and diabetes.
Shellfish, including clams and oysters, are among the most nutrient-rich foods that can be obtained from the sea along with seaweed. Vitamins and zinc are rich in iron, so it is said to be good for recovery from fatigue and anemia. It is also rich in taurine, which helps reduce blood pressure and blood cholesterol levels. Vitamin B2 contained in shellfish also prevents vision loss. If anyone wants to become a vegetarian, keep an eye out for clams. Although it is not meat, it has the nutrients of animal foods.
