Corn juice is troublesome, but delicious. It's much easier if you have a soymilk machine that can cook automatically. Buy sweet corn.
Mango juice is also delicious, but some people are allergic to mango, depending on personal preference ~ ~
Pineapple juice is not very delicious, tomato juice, not many people like it, carrot Sydney juice is not bad, fresh orange juice is best with yogurt, do you like sour? Lemon juice and grapefruit juice are both good ~ ~ ~ but add some yogurt or sugar to neutralize them. Too sour is bad for the stomach ~ ~
Generally, some concentrated juice or saccharin is added to the juice squeezed out by tea shops or food stores. Drinking in those places is not recommended ~ ~
