In the Catholic Church, fasting is the practice of abstaining from certain foods or drinks, either in whole or in part, for a specific period.
The purpose of fasting is to mortify the flesh and draw the mind and heart closer to God through prayer and self-denial.
During a fast, Catholics may be required to abstain from certain types of food or drink, such as meat, dairy products, and other wealthy or indulgent items. However, the specific rules and regulations surrounding fasting can vary depending on the individual’s age, health, and other factors.
In general, milk is not considered a food that would break a fast, as it is not a rich or indulgent item. However, the rules surrounding fasting can vary from one individual to another, so it is always best to consult with a spiritual director or other trusted spiritual advisor for guidance on the appropriate fast.
