What should I eat and drink to eliminate or at least reduce the gas and bloating in my system?

Try LactoseFree diet. A common cause of gas and bloating is lactose intolerance, even if you have not had problems with milk in the past. Lactose intolerance can start at any time, and symptoms can vary from day to day. Try a lactose-free diet for 1-2 weeks (no regular milk, cheese, ice cream, cottage cheese, sour cream, ranch dressing, yogurt, or milk chocolate). You may drink lactose-free milk, soy or almond milk.
