A few asthma symptoms are shortness of breath, chest tightness, coughing especially at night, fatigue and wheezing. There are medications available to ease the symptoms of breathing disorders. There are also certain foods that should be avoided by people with breathing issues because they trigger symptoms: 1. Cabbage This vegetable may be rich in nutrients, but it is also known to cause gas and bloating. Cabbage contains a type of sugar called raffinose, our bodies cannot break this type of sugar down so it ferments in the intestines causing gas. Excess gas and bloating limits lung capacity, which makes it a bad food choice for people with breathing problems. 2. Citrus fruits and drinks Consumption of citrus fruits and drinks is not a good choice for people with breathing issues. They are too acidic and can cause gas and bloating.
