Baking

• When baking, an individual who has high blood pressure should attempt to cut out baking soda and baking powder from his recipes. There isn't a good substitute for either of these ingredients, so it is best to leave them out completely.
  
  

Dairy

• Most cheese and butter that is sold in stores comes salted. Unsalted dairy products are generally available and someone with hypertension should buy these unsalted products.
  
  

Snacks

• Salty snacks should definitely be avoided. This includes chips, some types of popcorn and foods that are pickled. Many chips and popcorn are now available in low-salt or no-salt versions, so those are still an option.
  
  

Canned Foods

• Most canned foods contain a large amount of sodium in order to preserve them. Always check the label on canned foods and avoid those with a high sodium content.
  
  

Caffeine

• It is important to avoid caffeine if possible, as it has been linked to high blood pressure. Drink decaffeinated coffee and tea, and replace sodas with caffeine-free versions, fruit juice or water.
