WHOLE GRAINS AND BLOOD PRESSURE CONTROL

WHAT’S THE RELATION?

Whole grains are an important part of a healthy diet. Eating more whole-grain foods regularly also may reduce your chance of developing high blood pressure.

And if you already have high blood pressure, eating more whole-grain foods may help lower your blood pressure. Learn more from Dr. Sheldon Sheps, an emeritus Mayo Clinic hypertension and peripheral vascular diseases specialist.

What foods are in the Grains Group?

Any food made from wheat, rice, oats, cornmeal, barley or another cereal grain is a grain product. Bread, pasta, oatmeal, breakfast cereals, tortillas, and grits are examples of grain products.
Grains are divided into 2 subgroups, Whole Grains and Refined Grains. Whole grains contain the entire grain kernel ― the bran, germ, and endosperm. Examples of whole grains include whole-wheat flour, bulgur (cracked wheat), oatmeal, whole cornmeal, and brown rice. Refined grains have been milled, a process that removes the bran and germ. This is done to give grains a finer texture and improve their shelf life, but it also removes dietary fiber, iron, and many B vitamins. Some examples of refined grain products are white flour, de-germed cornmeal, white bread, and white rice.
Most refined grains are enriched. This means certain B vitamins (thiamin, riboflavin, niacin, folic acid) and iron are added back after processing. Fiber is not added back to enriched grains. Check the ingredient list on refined grain products to make sure that the word “enriched” is included in the grain name. Some food products are made from mixtures of whole grains and refined grains.

How many grain foods are needed daily?

The amount of grains you need to eat depends on your age, sex, and level of physical activity. Recommended daily amounts are listed in this table below. Most Americans consume enough grains, but few are whole grains. At least half of all the grains eaten should be whole grains.

What counts as an ounce-equivalent of grains?
In general, 1 slice of bread, 1 cup of ready-to-eat cereal, or ½ cup of cooked rice, cooked pasta, or cooked cereal can be considered as 1 ounce-equivalent from the Grains Group. The table below lists specific amounts that count as 1 ounce-equivalent of grains towards your daily recommended intake. In some cases the number of ounce-equivalents for common portions are also shown.
*WG = whole grains, RG = refined grains. This is shown when products are available both in whole grain and refined grain forms.

Pneumonia: Risk factors and prevention  Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus, causing a cough, fever, chills and difficulty breathing. Pneumonia can range in seriousness from mild to life-threatening. It is most serious for infants and young children, people older than age 65, and people with health problems or weakened immune systems. Vaccines are available for adults and children to prevent some types of pneumonia. Additional prevention strategies include hand-washing; not smoking; and keeping your immune system strong by getting enough sleep, exercising regularly and eating a healthy diet.

Diabetes management: Aspirin therapy for heart health  Because diabetes increases your risk of cardiovascular events, daily aspirin therapy typically has been recommended as part of a diabetes management plan. Research has shown that aspirin therapy effectively reduces the risk of heart attack and clot-related strokes if you’ve had a previous cardiovascular event. What’s not clear is whether aspirin lowers the risk of a cardiovascular event if you haven’t experienced one before and you aren’t experiencing symptoms of peripheral artery disease. Learn more from Dr. M. Regina Castro, a Mayo Clinic endocrinologist.

Hearing aids for high-frequency hearing loss  Hearing aid manufacturers continue to make improvements by developing hearing aids that are more effective for all types of hearing loss, including high-frequency hearing loss. The advent of digital technology in the mid-1990s resulted in significant hearing aid improvements. Digital hearing aids can be adjusted to match an individual’s unique hearing loss.

Can vitamin C improve mood and decrease anxiety?  The link between vitamin C and mood might seem surprising, but people who have vitamin C deficiency often feel fatigued or depressed. Studies have shown improved mood and lowered anxiety from taking vitamin C — even in one group not known to have low vitamin C levels. Learn more from Dr. Brent Bauer, director of Mayo Clinic’s Complementary and Integrative Medicine Program.
