I think the most affordable thing is to buy a few cans of milk for parents to drink, because milk has high nutritional value and is a good nutritional supplement for middle-aged and elderly people.

Old people often drink milk, which is good for their health. The benefits of drinking milk for the elderly mainly include promoting sleep, supplementing protein, supplementing calcium to prevent osteoporosis, maintaining skin elasticity, increasing blood vessel elasticity, and reducing cardiovascular and cerebrovascular diseases such as coronary heart disease and cerebral infarction.

So when you go home for the New Year, I recommend that you buy some cans of milk for your parents, which is the healthiest food. And it's the same as sending health to parents.
