Spinach



Does Popeye love spinach without reason?
Does Popeye have great health due to his genes?
No! It’s because Popeye loves spinach!!


Because spinach has great amount of lutein(葉黃素), vitamin E, antioxidants, spinach has been considered as the golden dish in green vegetable. Spinach also contains a large number of β-carotene which can prevent reactive oxygen and then it can prevent cancerous cell from division and reproduction. Moreover, β-carotene can also enhance the immune cells to inhibit cancer cells to grow.

Regular intake of spinach can prevent liver cancer, ovarian cancer, colon cancer, colorectal cancer, prostate cancer.
Spinach contents highest folate(葉酸) among vegetables that can repair tumor suppressor factor and inhibit cancer spreads. If we combine spinach with vitamin B12, it also has function of anti-oxidation.
Besides, spinach with rich chlorophyll and fiber can prevent cells from genetic damage and maintain the normal function of cells.

In addition, the consumption of spinach can reduce blood cholesterol. Spinach contains large amounts of iron and trace amounts of manganese can improve and prevent anemia

However, spinach also contain oxalic acid(草酸). The oxalic acid in spinach hinders the absorption of calcium. When people intake spinach and high calcium food at the same time, calcium would not be absorbed.

Once oxalic acid gets into the blood, it would mingle with calcium which would be the cause of kidney stones. The better way to avoid this problem is to boil spinach into vegetable soup because great amount of oxalic acid would be dissolved. After eating spinach, don’t forget some water, it would also reduce the chance to get calcium oxalate stones(草酸鈣結石).

Furthermore, spinach also contains a lot of nitrate(硝酸鹽)which would later become carcinogenic nitrosamines(亞硝胺) once mingles meat in human’s stomach and cause some other gastrointestinal cancers. But fortunately, it can dissolve, so abandoning the boiled soup spinach is the simple detoxification method. Or don’t eat meat if you have already had some spinach soup. Besides, drinking green tea is another way to prevent nitrate turn into nitrosamines in the stomach.
