Bloating and gas are commonly associated with food intolerances, making this the correct answer. Food intolerances occur when the digestive system reacts poorly to certain foods, often due to the lack of specific enzymes or an inability to break down certain substances. For example, lactose intolerance arises from a deficiency in lactase, the enzyme necessary to digest lactose found in dairy. When these undigested food components reach the large intestine, they can ferment, resulting in symptoms such as bloating, gas, and discomfort.

The other options describe reactions that are not typically linked to food intolerances. Bruising is usually associated with issues related to blood clotting or deficiencies in certain vitamins rather than digestive problems. Anaphylaxis is a severe, potentially life-threatening allergic reaction, often linked to food allergies rather than intolerances. Chest tightness may be related to respiratory issues or anxiety rather than digestive disturbances caused by food intolerances.
