Hypotension, or low blood pressure, can cause just as serious side effects and complications as high blood pressure, according to the Mayo Clinic. Low blood pressure can cause dizziness and fainting. It can be life threatening as well. A blood pressure reading of 90 over 60 is considered low. A number of conditions can cause low blood pressure, including insufficient nutrients in your diet.
Carbohydrates
For some people with postprandial hypotension, the low blood pressure occurs after eating. The condition commonly affects the elderly and those with Parkinson's disease or autonomic nervous disorders. You may undergo severe blood pressure drop if you have high blood pressure and eat a large meal, heavy in carbohydrates. Small, low-carb meals are best to avoid symptoms if you have this disorder. Limit your consumption of potatoes, pasta, rice and bread.
Sodium
People with high blood pressure are urged to lower their salt intake because sodium increases blood pressure. If you have low blood pressure, increasing the amount of salt in your diet may help your numbers rise. However, you should check with your doctor before increasing your salt intake or before undertaking any home remedies for your condition to confirm doing so is safe for you and doesn't interfere with any other treatments you may be undergoing.
B12
According to the American Heart Association, insufficient levels of folic acid and vitamin B12 can lead to anemia, which can create low blood pressure. Vitamin B12 is vital for healthy blood and nerve cell development. B12 combines with protein in the stomach and is absorbed through the blood. Dietary sources of vitamin B12 include meat, eggs and dairy. Plants do not contain vitamin B12. Many fortified cereals have added B12 and folic acid. Folic acid is needed to prevent anemia and to produce new cells. In addition to fortified cereal, you can get folic acid from spinach, black-eyed peas and liver.
Magnesium
According to the Office of Dietary Supplements, magnesium is the fourth most abundant mineral in our bodies, with 50 percent concentrated in the bones. The other half supports more than 300 biochemical reactions in your body. Magnesium plays a role in blood pressure. The green chlorophyll in vegetables such as spinach and kale contain magnesium. Other dietary sources include cashews, almonds, soybeans and halibut.
Other Dietary tips
Low-blood sugar levels can lead to low blood pressure, according to the American Heart Association, particularly in diabetics. A decrease in blood volume that often occurs when you become dehydrated can cause your blood pressure to drop. Increase the amount of water you drink, or consume sports drinks that contain electrolytes when you are exercising to prevent a drop in blood pressure. Caffeine also may help raise your blood pressure, according to the Mayo Clinic.
