Food to avoid when treating high blood pressure

Share This

Nearly a third of Americans have high blood pressure. Another third have prehypertension, a condition in which blood pressure is higher than normal but not quite high enough to be diagnosed as hypertension. If you have high blood pressure or prehypertension, studies have shown that you can lower your blood pressure by eating a healthy diet. A healthy diet emphasizes lean protein, whole grains, low-fat dairy, and fruits and vegetables. Unfortunately, there are also a lot of foods that can hinder your ability to lower your blood pressure. Click through this slideshow to learn about 10 foods that may prevent you from properly treating hypertension.


Salt and sodium are villains when it comes to living with high blood pressure and heart disease. The Dietary Guidelines for Americans suggests that people with hypertension or prehypertension limit their daily sodium intake to just 1,500 milligrams. Currently, the average American eats more than twice that amount, or about 3,400 milligrams a day.

More than 75 percent of the sodium you eat in a day comes from the packaged foods you eat, not what you add at the table with a saltshaker. Some of the saltiest sources of pre-packaged foods include deli meat, frozen pizza, fruit and vegetable juices, canned soup, and canned or bottled tomato products.


Preserving any food requires salt. The salt stops the decay of the food and keeps it edible longer. However, salt can take even the most innocent cucumber and make it a sodium sponge. The longer vegetables sit in canning and preserving liquids, the more sodium they can pick up. A whole dill pickle spear can contain as much as 300 milligrams of sodium. Reduced sodium options are available, containing about 100 milligrams of sodium each.

Canned Soups

They’re simple and easy to prepare, especially when you’re in a time crunch or not feeling well. However, canned soups are filled with sodium. Canned and packaged broths and stocks can be bad, too. Some soups can have 890 milligrams of sodium or more in just one serving. If you consume the entire can, you’ll be taking in 2,225 milligrams of sodium. Low-sodium and reduced-sodium options are available. A better option is to make your own from a low-sodium recipe to keep the salt in check.


You likely already know that excessive sugar intake has been linked to increased cases of weight gain and obesity. But did you know that high sugar intake is also linked to high blood pressure? Sugar, especially sugar-sweetened drinks, has contributed to an increase in obesity in people of all ages. High blood pressure is more common in individuals who are overweight or obese. Currently, the USDA does not have a recommended daily limit for sugars, but the American Heart Association recommends that women limit added sugar intake to 6 teaspoons per day, and that men keep themselves restricted to 9 teaspoons per day.

Chicken Skin and Packaged Foods

People with hypertension should avoid saturated and trans fats. Chicken skin is high in saturated fat. Full-fat dairy, red meat and butter are, too. Trans fats are created in a process called hydrogenation. Liquid oils are infused with air to make solid oil. Trans fats are found naturally in small amounts in fatty meats and dairy products. However, the biggest contributor of trans fats is packaged and prepared foods. Hydrogenated oils increase packaged foods’ shelf life and stability.

According to the CDC, consuming too many saturated and trans fats increases your LDL, which is bad cholesterol. High LDL levels may worsen your hypertension, and may eventually lead to the development of coronary heart disease.


If you have hypertension or prehypertension, now may be the time to kick your coffee habit. Your morning cup (or cups) of Joe can actually cause a temporary spike in blood pressure. If you’re a regular coffee drinker, this may be contributing to your hypertension. In fact, any caffeinated drinks may cause an increase in your blood pressure—this includes soda or caffeinated tea.


When it comes to high blood pressure, alcohol is a double-edged sword. Small to moderate amounts of alcohol may actually lower your blood pressure, but drinking too much alcohol can increase your blood pressure, even for people who only drink occasionally. According to the Mayo Clinic, having more than three drinks in one sitting can cause a temporary spike in blood pressure, and repeated drinking can lead to long-term blood pressure problems.

Alcohol can prevent any blood pressure medications you may be taking from working effectively. In addition, alcohol is full of calories and can lead to weight gain. People who are overweight or obese are more likely to have high blood pressure.
