Eating sukuma wiki (kale) minimises chances of heart diseases and helps to fight five types of cancers, a study released Tuesday shows.
The research commissioned by the World Healthiest Food, an international NGO, shows that the vegetable also helps lower cholesterol levels.
This minimises the risk of heart diseases. The vegetable lowers the risk of bladder, breast, colon, ovary, and prostate cancers.
Nutrition consultant Yusuf Captano said the health benefits associated with kale included blocking the growth of cancer cells and reducing the risks of coronary artery disease.
“Kale, along with other vegetables contains dark vegetable compounds. These compounds play an important role in preventing the development of certain cancers,” said Dr Captano.
He advised that to remain healthy, people should eat kale two to three times a week.
However, the sukuma wiki must be cooked properly.
“We recommend that kale should be steamed for five minutes,” said the expert.
Dr Captano however warns that those who suffer from ulcers should limit their intake of kale.
The vegetable contains a high amount of vitamin K, which can interfere with blood thinning.
“When it is cooked fresh, anyone can eat it but if it is stored then cooked later, ulcers patients should not take it because of the acidic factor,” he said.
The researcher also noted that if overcooked, kale may lose its nutritional value.
In addition, the elderly are advised not to eat too much of the vegetable.
The American Association of Retired Persons warns its members not to eat too much kale as it can destabilise their digestive system.-nation.co.ke
