The National Heart, Lung, and Blood Institute (NHLBI) created what is known as the Dash Diet. The NHLBI falls under the National Institutes of Health. On the Dash Diet, Dr. Oz recommends it not only for people who not only want to lower their blood pressure, it's also excellent for those who want to lose weight or protect against certain diseases.

Celebrity doctor Dr. Oz explains on his website, "Even though the diet is meant to target blood pressure, it has also been shown to offer protection against osteoporosis, cancer, heart disease, stroke and diabetes. Because it promotes healthy eating and snacking, the Dash diet may also help people lose weight."

About the Dash Diet, Dr. Oz further explains that the main goal is to lower the level of sodium in the body. A low sodium level will lead to lower blood pressure.

Dr Oz further states, "Basically, the DASH diet requires the ample consumption of whole grains, fruits, vegetables and low-fat dairy. There can be limited consumption of fish and poultry, while red meat, sweets and fatty foods should be consumed sparingly."

The famous doctor recommends people eat 6 or fewer ounces of lean meats daily if they want to follow the Dash Diet. Examples of lean meats are fish or poultry. Red meat is to be avoided in the Dash Diet since these contain higher levels of cholesterol and fat.

For whole grains, about 8 servings a day are suggested by Dr. Oz. Examples of whole grains are rice and whole wheat pasta. Whole-wheat food contains more fiber and nutrients compared to refined grains.

In terms of fruits and vegetables, Dr. Oz suggests about 5 servings of fruit daily and another 5 servings of vegetables. Green leafy vegetables can be mixed with the likes of tomatoes and broccoli.
