High blood pressure is also known as hypertension, and more than one in four adults in the UK are affected, according to the NHS.
Certain foods in your diet can negatively impact high blood pressure, such as those that contain high levels of salt.
Blood Pressure UK states eating too much salt is the biggest cause of high blood pressure and an adults should eat no more than 6g of salt a day.
Most of the salt we eat every day is hidden’ which means it’s already in processed foods like bread, biscuits and breakfast cereals, and prepared ready meals or takeaways, and frozen pizzas are another surprising food people with high blood pressure should avoid.
According to the charity, this hidden salt accounts for around 75 per cent of the salt we eat – only 25 per cent comes from the salt we add while cooking or at the table.
Nutritionists at Healthline say processed deli meats should be avoided if you have hypertension.
The site explains: “Processed deli and lunch meats can be real sodium bombs. These meats are often cured, seasoned, and preserved with salt.
“According to the U.S. Department of Agriculture, a two ounce serving of some lunch meats could contain 500mg of sodium or more.
“If you have a heavier hand with the cold cuts, you’ll get even more sodium. Add bread, cheese, condiments, and pickles, and your simple sandwich can quickly become a sodium trap.”
Frozen pizza is another food nutritionists recommend you avoid.
Healthline says: “All pizzas can be bad for people watching their sodium intake. The combination of cheese, cured meats, tomato sauce, and crust adds up to a lot of sodium. But frozen pizza is especially dangerous for people with hypertension.
“To maintain flavour in the pizza once it’s been cooked, manufacturers often add a lot of salt. One serving of a frozen cheese or meat-and-cheese pizza can contain as much as 982 mg of sodium, sometimes even more. The thicker the crust and the most toppings you have, the higher your sodium number will climb.”
