Dietary contraindications for Chinese yam
1. Diabetic patients should not eat too much: Although the mucilage protein contained in yam has the effect of lowering blood sugar, yam is a root and tuber food with a relatively high starch content. If eaten too much, it will not lower blood sugar but instead cause blood sugar to rise. Therefore, people with diabetes should not eat an excessive amount of yam at one time. If some patients prefer to eat yam, they should appropriately reduce the amount of staple food, otherwise it will have the opposite effect.
2. Eat less yam when eating hot pot: Yam itself is a tonic. When eating hot pot, the effect of spicy seasonings gives the neutral-natured yam a certain heating property, making it easy to cause internal heat. Therefore, it is best to eat less yam when eating hot pot.
3. Avoid taking alkaline drugs such as baking soda: When eating yam, do not take alkaline drugs such as baking soda tablets at the same time, so as to avoid baking soda rendering the amylase in yam ineffective.
4. Prostate cancer or breast cancer: The diosgenin component contained in yam can synthesize hormones in the human body, such as testosterone and estrogen. Therefore, it is not suitable for men with prostate cancer or women with breast cancer to eat it.
5. Constipation patients should eat as little as possible: Yam is rich in starch. For those with chest and abdominal distension, dry stool, and constipation, it is best to eat less. After these symptoms ease, yam can be eaten again. In addition, patients with peptic ulcers and cirrhosis should choose cooking methods such as steaming and stewing, and avoid quick stir-frying and sweet and sour cooking.
