Beer: Alcohol can dehydrate you and make your body flushed–a process called vasodilatation, which is caused by the widening of blood vessels.

We know that when the pulse rate is constant, vasodilatation causes a fall in diastolic pressure and a rise in pulse pressure.

We may probably associate the general tendency to vasodilatation during early pregnancy with the tendency to goitre; Freund found an increase of the thyroid in 45 per cent. of 50 cases.

Abnormal vasodilatation seriously interferes with the normal circulation, and causes venous congestion, abnormal increase in venous blood pressure, and the consequent danger of shock and death.

Alcohol taken before meals on an empty stomach causes sudden vasodilatation after absorption.
