Is it advisable for a man to add milk coffee and wait an hour before drinking or the prior it?

There's no scientific basis or health recommendation to wait an hour after adding milk to coffee before drinking it. It's perfectly fine to enjoy your coffee immediately after adding milk.

However, here's why you might hear this advice sometimes:

* Taste preference: Some people prefer their coffee to cool slightly before adding milk, as they find the flavor more balanced that way.

* Milk separation: If you add milk to very hot coffee, it might curdle or separate slightly. Waiting a bit allows the coffee to cool down and minimizes this effect.

Ultimately, it's a matter of personal preference. Enjoy your coffee however you like it!
