Some foods are more prone to produce gas: these include beans, corn, apples, raisins, bananas, prune juice and apple juice. Often the reason is that some of the food escapes digestion and absorption because of too rapid eating or drinking with meals. The food residues are then made into gas when they reach the colon. Saliva needs to be mixed well with all food and drink. Solid food needs to be chewed to a cream before it is swallowed.
The eating of fresh, raw fruits and vegetables, seeds and nuts can boost enzyme production by the intestinal tract. Chew them well.

Following are some causes of gas in the colon:

1. Overtaxing the digestive system
   • Eating too fast or too slowly. 30-45 minutes is a desirable mealtime.
   • Inadequate chewing: chunks escape, which cannot be completely digested.
   • Eating too much, the digestive tract being unable to handle the excess food.
   • Eating too often. Meals too close together or off schedule.
2. Drinking with meals or eating too much of liquid foods. Fluids dilute the stomach juices.
3. Tension, noise, or distractions at mealtimes.
4. Improper cooking: Grains and legumes may require several hours.
5. Wrong combinations – fruits and vegetables – milk, eggs, and sugar.
6. Inadequate water between meals.
7. Eating foods that disagree. Milk sensitivity is a frequent cause of gas.
8. Reclining after meals.
9. Vigorous exercise too soon after eating.
