The elderly should eat some cool, healthy and nourishing food. Let me introduce to you a specialty of Jiangxi: "Kudzu Fen". Arrowroot is made from wild kudzu root after being beaten, and then the juice leaves are dried and processed.
You can search on Baidu for the benefits of eating arrowroot powder for the elderly.
The one benefit I can confirm is the blood pressure.
The method of eating arrowroot starch is: boil the water in a pot, then put a little arrowroot starch into the pot. When it turns into a paste, which is the same as porridge, it is ready to eat. It tastes a little sweet, but don’t worry, it is definitely not sugar.
It's so sweet, I hope the elderly can like it.
The best kudzu powder in Jiangxi is the kudzu powder from Hengfeng, Shangrao, which is also the hometown of kudzu in China.
