Why does Popeye eat spinach?

This is because the nutritional composition of spinach was wrong at that time, and the iron content changed from 3.5 mg to 35 mg. That led to spinach being pushed to the altar that year.

Extended data:

When spinach was pushed to the altar, it happened to be the creative period of Popeye. Spinach naturally became a good propaganda point, and at that time, a spinach cannery sponsored animation production. An image of Popeye who likes to eat spinach was born, and Popeye was almost called phenomenal animation at that time. Popeye likes to eat spinach, which has also influenced the attitude of countless children to spinach, triggered the upsurge of eating spinach for the whole people, and greatly promoted the development of spinach cultivation.

In fact, all this is caused by a mistake, and the nutrition of spinach itself is not so exaggerated. If it weren't for the mistake at that time, the iron content of spinach was wrongly written as 10 times, there would not be such a classic Popeye image. Popeye itself is also a very successful marketing case, not only a commercial success, but also a success in improving the health level of the whole people.
