I recently ran across an interesting article posted by The Vocal Gym covering what you should and shouldn't consume before singing. Every vocal instrument (body) is different and that means that they are affected differently by food. Eating several small meals spread throughout the day is better for your digestion than 2 or 3 large meals, because smaller meals help you steady your metabolism as they prevent your body from ´crashing´ after a large meal.
What NOT to consume before singing:
- Dairy
- Processed sugar
- Fried food
- Caffeine
- Alcohol
- Red meat
- Spicy food
What TO consume before singing:
- Water.
- Fresh fruits and vegetables
- Honey
- Nuts
- Chicken/Fish
Every singer should get to know their own instrument and eat according to what they observe. Some people for example get bad acid reflux from citrus fruits, while others can eat several oranges throughout the day without noticing a thing.
