Meat can be frozen, leafy vegetables can be bought less, and medicine can be taken two days ago. Cruciferous vegetables such as broccoli can be kept for two more days, while peeled and tuber vegetables such as zucchini, eggplant, carrots, lanterns and peppers can be kept for longer. Speaking of the freshness of food, I think it is better to care about the loss of nutrients than to order takeout every day. Worried about what to take out today, it is better to control yourself and decide what to eat the next day in advance. And eating out is nutritious and full, which is really expensive. For office workers, there is another way to be lazy. I have used it myself. Before going to bed, I throw rice and meat into the electric cooker for stew, so that I can fry at most one dish the next morning and pack it up and leave.
