Which yam is the most nutritious, and which yam has high nutritional value

I feel that the iron stick yam is nutritious, and eating it is good for the stomach and intestines, strengthening the spleen and stomach.

Iron stick yam has high nutritional value.

Iron stick yam: It is one of the many yam species, and there are traces like rust on the iron stick yam, so it is named iron stick yam. According to the different geographical locations, the iron stick yam is divided into two kinds of iron stick yams: sandy soil near the Yellow River and muddy soil; Nutrients:

The skin of the iron stick yam is thin and firm, and the main nutrients including starch, protein, free amino acids, mucus and minerals are higher than that of ordinary yams, and its reducing sugar content is low, not easy to turn yellow, and the moisture content is also low, which is very easy to preserve. In addition, because of its high starch content and sweet taste, the edible value of iron stick yam is higher than that of ordinary yam; The first of many yams: The reason why the iron stick yam is the first among many yams is because the origin is limited and the production is limited.

The yield of iron stick yam is lower than that of ordinary yam, only one-quarter to one-third of that of ordinary yam; Efficacy: Iron stick yam is rich in DHEA, which is a very important activity substance in human life activities, and the main health care effects of DHEA are anti-aging, enhancing immune function and improving sexual function. The mechanism of its health care effect is that it can be converted into male hormones or estrogens according to the needs of the body to supplement the hormonal imbalance caused by aging and disease.

The best yam species is the iron stick yam.

Compared with ordinary yams, iron stick yams are "short", "thin", "long burrs", "have heads and tails", and "delicate sections".

The cut surface of the iron stick yam is delicate, the color is like porcelain white, the quality is like porcelain firm, and the fine and pure white is like porcelain like jade. The common yam has a large head, sparse texture, no porcelain reflection, and obvious granularity.

Iron stick yam contains less reducing sugar, so the section is not easy to turn yellow. After cutting ordinary yams, they will quickly turn yellow if left untreated. It is very resistant to cooking when steaming, and it does not rot after cooking for a long time. The taste is delicate, floury and powdery, sweet and delicious, with a slight medicinal taste.

The nutritional value of iron stick yam is high**?

The reason why the iron stick yam is the first among many yams is not in vain. The reason why it is ** is higher, firstly, the origin is limited, the "authentic" iron stick yam must be produced in the area of Jiaozuo in ancient Huaiqing Mansion, and secondly, the output is limited, and the output of iron stick yam is lower than that of ordinary yams, only 1 4 to 1 3 of ordinary yams.

Since the production area is limited, why not replace it with other yams? The reason is that the quality of the iron stick yam is irreplaceable, and the nutritional value is far beyond that of ordinary yams. Although household use can be informal, but if it is a medicinal material, it is best to take an iron rod and a yam.

Therefore, scarcity is expensive, and iron stick yams, especially iron stick yams, are naturally much more expensive.
