Can you drink grapefruit juice on a low carbohydrate diet?

A cup (240 ml) of unsweetened grapefruit juice contains about 12 grams of carbohydrates, which is relatively low compared to other fruit juices. Additionally, grapefruit juice is a good source of vitamin C, potassium, and other essential nutrients. However, it's important to consume it in moderation as drinking excessive amounts can lead to negative side effects such as diarrhea, nausea, and headaches.
