My father-in-law is coming to see us, and my husband asked me to buy food. I don't know what old people like to eat.

Old people have heavier tastes than young people, heavier spices than usual, and their teeth are not very good. Consider eating something chewy.

Such as cold tofu, soybeans, loofah egg soup, fried mushrooms with black fungus, stewed eggs with shrimps, scrambled eggs with tomatoes, etc.

For meat, buy fish, steamed fish, shrimp, roast duck and fresh foie gras.

And in summer, my appetite is not big, so I just need to prepare more food.
