In most healthy adults, low blood pressure does not cause problems or symptoms. In fact, it may be normal for you. For example, people who exercise regularly often have lower blood pressure than people who are not as fit.
If you want to give your family's daily diet a "heart health makeover," start with your kitchen. It stands to reason that how we fill our kitchen -- in the pantry, refrigerator, or freezer -- sets the pattern for what we eat.
If you stock your kitchen with nutritious but flavorful whole foods, you and your family are more likely to eat a heart-smart diet and reduce your risk of cardiovascular disease.
The American Heart Association recommends these tips for a heart-healthy diet:

But if your blood pressure drops suddenly or causes symptoms like dizziness or fainting, it is too low. It can cause shock. Shock can be dangerous if it is not treated right away.
Blood pressure is a measure of how hard the blood pushes against the walls of your arteries as it moves through your body. Blood pressure consists of two numbers: systolic and diastolic.
The systolic (higher) number shows how hard the blood pushes when the heart is pumping.
The diastolic (lower) number shows how hard the blood pushes between heartbeats, when the heart is relaxed and filling with blood.
Someone with a systolic pressure of 120 and a diastolic pressure of 80 has a blood pressure of 120/80, or "120 over 80." Normal blood pressure is lower than 120/80.
Low blood pressure does not have a specific number where it is too low. Most doctors consider blood pressure to be too low when it causes symptoms or drops suddenly. In general, low blood pressure symptoms happen when blood pressure is less than 90/60.
What causes low blood pressure?
Some of the causes of low blood pressure include:
Getting up after you sit or lie down. This can cause a quick drop in blood pressure called orthostatic hypotension.
