No, eating apples before going to bed is better, which can improve kidney function. Eating apples on an empty stomach will increase the burden on the stomach, especially in the morning, and it will also stimulate the stomach. Don't listen to others say that eating apples in the morning is nutritious, which will only harm you. Without health knowledge, apples contain a lot of sugar, which can decompose sugar and acid, and digest food just like our stomach acid. If you eat apples on an empty stomach, there will be no food to digest, but more stomach acid will accumulate, which may cause stomach problems over time.
