There are seven diseases that are easily caused by vitamin C deficiency, and you must pay attention

Vitamin deficiency or vitamin C deficiency leads to ().

a.Oleus osacea.

b.Scurvy.

c.Neonatal neurological malformations.

d.Keshan disease.

Correct answer: B

Answer] :d vitamin C (anti-coincidence ascorbic acid) is necessary for collagen formation, which helps to maintain the integrity of interstitial substances such as connective tissue, bone-like tissue, and filial dentin, and severe deficiency can cause scurvy, which is an acute or chronic disease characterized by hemorrhage, osteoid, and dentin formation.

a.Prolonged clotting time.

b.When clotting, the argument is shortened and laughed.

c.Increased permeability and fragility of the blood vessel wall.

d.Decreased permeability and fragility of the blood vessel wall.

Correct answer: d

Since vitamin C is readily available in common fruits and vegetables, meeting the recommended daily allowance (RDA) is usually not a problem. Let's take a look at how much we really need and what the effects are on our bodies when we don't get enough ascorbic acid in our diet.

Vitamin C requirements.

The RDA for vitamin C is 75 mg per day for women, 90 mg per day for men, an additional 10 mg for pregnant women, and an additional 45 mg for breastfeeding women. RDA now indicates that smokers need at least 100 mg of vitamin C per day.

These amounts are several times the amount required for **deficiency symptoms. Even so, many people believe that these levels are not enough to provide optimal nutrition, and this has more to do with the antioxidant properties of vitamin C than with preventing deficiency.

Insufficient. The classic vitamin C deficiency is scurvy. The early signs of this disease are bleeding gums and bleeding under the skin, resulting in tiny bruising. Deficiency can progress to the point where it leads to poor wound healing, anemia, and impaired bone growth.

The body usually stores about 1,500 mg of vitamin C at a time and does not experience symptoms of deficiency until the body pool falls below 300 mg. In a well-nourished person, it takes a few weeks for this decline to appear on a diet that does not contain vitamin C.

Since only 10 mg of vitamin C per day is needed to prevent scurvy, the disease is rare these days. Even in the absence of signs of scurvy, low vitamin C intake can impair many bodily functions, including the ability to remove cholesterol from the body and the immune system's ability to fight off infection and disease.

Smokers and women who use oral contraceptives have lower-than-normal levels of vitamin C in their blood. Given these findings in smokers, the current RDA increases the amount of vitamin C required by smokers. They may need 100% more vitamin C in their diet than non-smokers.
