Yes, generally, it is safe to drink milk after eating eggs.
The idea that combining milk and eggs is harmful is largely a myth. The reference indicates that it is absolutely safe to consume milk and eggs together, whether you drink milk after eating boiled eggs, or vice versa, or consume them together.
However, some individuals might experience digestive discomfort after consuming eggs, which is not necessarily related to drinking milk afterward. This discomfort may be due to individual sensitivities to eggs or underlying digestive issues. If you consistently experience stomach problems after eating eggs, whether or not you drink milk, you may want to consult a healthcare professional.
In summary, for most people, there's no inherent danger in drinking milk after eating eggs. Any discomfort is more likely due to an individual's reaction to eggs themselves, rather than the combination with milk.
