Red hearts have higher sugar content.

This is because the sugar content of red-hearted pitaya is generally above 15%, while that of white-hearted pitaya is generally around 1%. The sugar content of natural white-hearted pitaya is not as high as that of red-hearted. In addition, red-hearted pitaya contains many vitamins, which also helps to lower blood sugar and blood fat, but white-hearted pitaya is not as good as it is.

Extended information:

Red pitaya is rich in dietary fiber, with 1.9 grams of total fiber per 1 grams. Eating about 4-5 grams of pitaya at a time can consume nearly 8-1 grams of fiber.

Dietary fiber can not only increase the amount of defecation, but also promote intestinal peristalsis. Studies have confirmed that if the daily dietary fiber intake is less than 12 grams, the weight of defecation will be less than 1 grams. The fermentability of dietary fiber can promote the expansion of feces and increase the amount of defecation, reaching the normal level of 16~2 grams per day.

In addition, many constipation patients said that defecation is not clean. This shows that the peristalsis of the intestine is not enough. When dietary fiber is fermented in the intestine, it will produce carbon dioxide and hydrogen to promote intestinal peristalsis.
