Hello there!
Nick's vegetable intake should not exceed 20% of his total food consumption.
Therefore, Nick may consume 1/2 - 1 teaspoon of fresh vegetables every 1-2 days. However, watery foods like cucumber, should be consumed by the 1/4 teaspoon.
If Nick begins to produce diarrhea, please limit the amount of fresh food.
Please PM me for the full list of safe vegetables.
