Article: Many common food allergies or sensitivities can cause gas. Cut some of the most common food allergy triggers from your diet for 3 to 6 weeks and see if your symptoms improve. Then, reincorporate the foods one by one and see if your symptoms return. Common problem foods include:   Foods containing gluten, such as wheat, barley, and rye products. Dairy products. Corn. Soy. Sugar. Alcohol. Refined carbohydrates. High FODMAP foods (foods containing certain types of sugars). For more information about foods that are high or low in FODMAPS, take a look at this information sheet: https://patienteducation.osumc.edu/documents/lowfodmapdiet.pdf There are certain foods that are known to cause gas, and some people are more sensitive to them than others. If you experience gas problems regularly, consider avoiding or limiting these foods:  Legumes. Beans are difficult to digest because they contain a sugar called oligosaccharide that the body cannot break down because it doesn't produce the right enzyme to do so. The oligosaccharide molecules remain whole through most of the digestion process and produce gas in the small intestine. Foods high in fiber. Fiber has many health benefits, but eating a large amount of grains and fibrous fruits and vegetables can lead to gas. Don't stop eating these beneficial foods altogether, but you might want to avoid the ones that seem to give you the worst gas. Dairy products containing lactose. Many people are slightly lactose intolerant; that glass of milk you have in the morning might be contributing to gas. Soda and other carbonated or fizzy beverages. Fried foods and other fatty foods. Artificial additives. Sweeteners like sorbitol and mannitol lead to gas and diarrhea. Chewing gum. Alcohol. Vinegar. Caffeinated beverages. Spicy foods. Greasy, processed, and refined foods. Taking fiber supplements, laxatives, or antibiotics can cause gas. These irritate the bowels and remove the bacteria needed for properly digesting food. Taking the time to chew each piece helps to break down the food before it enters your stomach and intestines, creating less work for your digestive system. Chewing with your mouth closed can also help, since swallowing a lot of air can lead to gas. Changing the order in which you eat food can prevent the production of gas. Eating protein with or before fiber and carbohydrates allows your digestive system to work properly.  When you begin eating a meal, your stomach produces hydrochloric acid in anticipation of digesting protein. If salad or bread hits your stomach first, the acid gets used up before you ingest meat, fish, or another protein. The protein then ferments, leading to gas and bloating. Health food stores sell hydrochloric acid supplements that you can take to help you digest protein. These should be taken after the meal, so your stomach has the chance to produce as much acid as it can first. In order to properly digest your food, your digestive tract needs a good supply of healthy bacteria. Fermented foods supply your body with the type of bacteria it needs to break other foods down.  Try yogurt, kefir, and other cultured dairy foods. Make sure the label says that the product contains probiotics. Kimchi, sauerkraut, and other fermented vegetables also have good probiotic properties. Probiotics may help promote the growth of beneficial bacteria in your gut, while minimizing the presence of harmful bacteria. Having healthy gut flora can reduce symptoms of gas.   Talk to your doctor before starting probiotic supplements, and ask them which type of supplement may be most beneficial to you. Always purchase supplements that have been certified by 3rd party verifiers, such as USP, NSF, or Consumer Lab.
Question: What is a summary of what this article is about?
Try eliminating common allergens from your diet. Avoid foods that irritate your digestive system. Consider other indigestibles that might be causing gas. Chew your food well. Eat protein first. Eat fermented food. Use probiotic supplements.

Carbon dioxide, or CO2, can safely and effectively lower and stabilize your pool’s pH. A variety of CO2 systems for pools are available, some of which can automatically analyze your pool’s pH and adjust their output accordingly. These devices are available through specialty pool and spa supply stores.  Some CO2 systems are fully automated, while others have to be controlled manually. Consult a specialist at a pool supply store to determine what type of CO2 system is best for your pool. These systems can be expensive, ranging in price from $300-$10,000 USD. However, a CO2 system may ultimately save you money, since it minimizes the need for frequent pH and chlorine adjustments. Unless you have a lot of experience installing pool equipment, it is probably best to have a pool technician install the CO2 system for you. Consider consulting a professional before you purchase a CO2 system, so that they can help you determine whether the system is a good fit for your pool. Since CO2 can raise your pool’s total alkalinity, it is best not to use a CO2 system if your water already has a high total alkalinity (i.e., if water tests reveal it is over 125 ppm). CO2 is also less effective at lowering pH if your water is hard. Consult a pool technician to determine if your water conditions are right for a CO2 system.

Purchase a CO2 system for safer pH control. Have a professional install your system. Avoid using a CO2 system if your water is hard or high in total alkalinity.
