Some elements of your diet will be acidic, but the majority of it should be alkaline--it should fall somewhere between 7.35 and 7.45 on the pH scale, which is slightly alkaline. To accomplish this, you'll need to monitor how much acid is put into your body. Soda, caffeine, alcohol, fatty and processed foods are highly acidic and can cause acidosis, which characterizes itself in several negative ways.
When acid accumulates in the body, it can wreak havoc on the mouth. For instance, you may notice your saliva being more acidic, and mouth ulcers may develop. The corners of your mouth may crack and bleed and repeated infections in your throat or tonsils may develop. The teeth are often affected as well. The gums become inflamed and the teeth become loose in their sockets. Teeth may also be extra sensitive to hot or cold foods and can break easily.
Skin, Hair and Nail Signs
An overabundance of acid can negatively effect your skin, hair and nails. Your skin can dry out, you can develop hives or get irritation in areas where you sweat. Hair may fall out, break, develop split ends or look dull and lifeless. Nails can appear thin and can crack and break very easily.
People with too much acid in their bodies might notice signs of it in their eyes. The eyes may tear up very easily or appear irritated. The corneas and eyelids might become inflamed and bouts of conjunctivitis are common.
Mental & Emotional Signs
Having an acidic body can cause mental and emotional symptoms like a loss of interest in activities you used to love and a loss of motivation. Likewise, those with an acid problem might feel nervous, anxious, irritable or sensitive to loud noises. These people also tend to become depressed easier than others.
Acidity tends to show itself dramatically in the digestive tract. Those with too much acid will regurgitate it or suffer from acid reflux. Other stomach conditions like ulcers or gastritis can also develop.
