Pregnant women with coughs can eat sweet potato syrup. Sweet potato syrup has the following effects:

1. Sweet potatoes prevent emphysema

An animal experiment at the University of Kansas in the United States found that Smoking rats have low vitamin A levels in their bodies and are prone to emphysema; while smoking rats that eat vitamin A-rich foods have a significantly reduced incidence of emphysema. Why some long-term smokers live to be over 90 years old without developing emphysema may be related to the fact that their daily diet is rich in vitamin A. Researchers recommend that those who smoke or passive smoke should eat some vitamin A-rich foods such as sweet potatoes every day to prevent emphysema.

2. Sweet potatoes are good for the heart

Sweet potatoes are rich in potassium, beta-carotene, folic acid, vitamin C and vitamin B6. These five ingredients can help prevent cardiovascular diseases. . Potassium helps maintain fluid and electrolyte balance in the body's cells, maintaining normal blood pressure and heart function. Beta-carotene and vitamin C can resist lipid oxidation and prevent atherosclerosis. Supplementing folic acid and vitamin B6 can help reduce blood homocysteine ??levels, which can damage arteries and is an independent risk factor for cardiovascular disease.
