Page 48: Food hygiene community project

• Acidity:

• Effects: It is a burning sensation in the gut

and in the chest at times. It can further lead

to peptic ulcers and mouth ulcers if not

treated. This raises the stomach pH and

gives a restless and burning sensation.

often found complaining about stomach

upsets or constipation.

be asthmatic.

• Reason: Asthma has been found to be in higher

abundance in Kitchens where there are cockroach

infestations.

• Effects: The inside walls of an asthmatic's airways are

swollen or inflamed. This swelling or inflammation

makes the airways extremely sensitive to irritations and

increases your susceptibility to an allergic reaction.
