s oxalic acid, which can react w▓ith the calcium in bean curd in the inte▓stines and form insoluble precipitates of ca
lcium oxalate. The foods taken together affect the ab▓sorption of calcium. Bean curd and green onion The combts of differen
ination of bean curd and green onions may affect the absorption of calcium. Bean c
urd contains ▓plenty of nutrition like protein and calcium. But green onio▓ns contain a great deal of oxalic
acid. When calcium meets oxalic acid, the calcium oxalate they fo▓rm destroys calcium. If one eats be▓an curd mixed with green onions over a long tim▓e, it can lead to a lack of calcium causing spasms, oste▓omalacia and fractures. Milk and choc▓olate Believe it
or not, milk and chocolate do not match.▓ While milk is rich in protein and calc▓ium, chocolate contains oxalic acid. Eaten together,▓ the calcium from milk and the oxalic acid of chocolate can combine and form insoluble calcium oxalate, which i▓s not only indiges
tible but also can cause diarrhea. Milk and pomelo The protein in milk can react with the fruit acids in pomelos and make on
e's stomach feel bloated. The acid can also ov▓er-stimulate the stomach and cause diarrhea. Lactic acid drink and ham Many people like hav▓ing a sandwich with yogurt. However, ham and bacon in sandwiches, when taken with yogurt, could cause cancer.
