An excess of carbohydrates like cereals, white sugar, coffee, tea, chocolates and comparatively less quantities of vegetables and fruits in the diet may result in indigestion.
Due to indigestion gases are produced in the digestive tract, causing compression over the diaphragm in the region of the heart and lungs. This in turn, reduces the supply of oxygen to the tissues which raises the carbon dioxide level, causing general depression. The excessive and indiscriminate use of drugs also leads to faulty assimilation of vitamins and minerals Of the body and ultimately causes depression.
The use of aspirin leads to deficiencies of vitamin C and antacids can cause deficiencies of calcium and vitamin B. Diabetes, low blood sugar (hypoglycemia) and weakness of the liver, resulting from the use of refined or processed foods, fried foods and an excessive intake of fats may also lead to depression.
