Hydrate
I'm starting with this topic because it's summer right now and it's been a really hot one in Edmonton. One common contributor to bloating can be dehydration. Water and herbal teas are the best sources of hydration; peppermint and ginger especially have bonus properties to help with digestion as well! On the other hand, there are some sources that should be avoided if you are struggling with bloat, such as all carbonated beverages (including water), sweetened beverages, fruit juices, and dairy beverages. The exception to fruit drinks, would be adding fresh squeezed lemon to water. Lemon helps stimulate the digestive system, as does adding apple cider vinegar to your glass of water.
Eat
Even some healthy foods can cause bloating, especially if we aren't digesting them properly. This is why it is so important to chew your food really well. Be mindful when you eat a meal, eating slowly and chew the eff out of your food before you swallow it. Chewing our food thoroughly helps the amylase in our saliva begin the process of digesting starch. Eating on the go- in a rush, is also a no-no; proper digestion involves our parasympathetic nervous system, which is activated when we’re relaxed and compromised when we are in a state of stress.
I don't like to give the advice to eliminate any certain foods, especially ones that are good for us. In the case that I would start working towards eliminating foods, would be one of the last measures of intervention I would take after addressing all the other nutrition and lifestyle factors that contribute to bloating. That being said, it would only be beneficial to eliminate inflammatory promoting sources such as refined sugar, refined grains, and alcohol. Inflammation can wreak havoc on digestion. Often, even a temporary break can reduce inflammation and promote healing of digestive tissues.
Supplement
Digestive enzymes; Helps break down the food into smaller compounds that can be more easily absorbed and digested by your system
Probiotics; Can help support a healthy microbial balance in the gut. Which in turn, should help discourage or alleviate bloat. Don't forget to always keep them in the fridge, these guys need to be alive to do their job!
L-Glutamine; Tissues in the intestine use this amino acid as a fuel source to function well.
Evaluation
If you have digestive complaints that are not easily managed with the steps listed here, or if your symptoms have persisted for a while now, it might be time to see a health professional and have a proper evaluation to determine any underlying causes of chronic digestive discomfort. Once the cause has been determined I can help you with a more specific, in-depth nutritional intervention.
