The most cost-effective food in China. What is this? I prefer calories, that is, I spend a little money on healthy food with high calories.

Among high-calorie foods, potatoes and sweet potatoes are more cost-effective, while peanuts are more expensive. Pig head, as far as health is concerned, then the healthiest high-calorie diet we can buy in our daily life is eggs. Although eggs are a little expensive, from the perspective of all aspects of health and the comprehensive standard of price, eggs are the best source of healthy calories we can consume. Of course, other eggs are better, but they are generally more expensive than eggs.
