Tracking Food as Part of Your Blood Pressure Log

Food is something that can be broken down into a lot of various categories, so it’s a highly personalized metric. For example, I eat a LCHF (low carb/high fat) Keto diet, so I keep track of my carbohydrate intake in my log. If you’re interested in how your diet affects your blood pressure, then you should make an effort to track your food in relation to your blood pressure. Here are some examples of food categories you can track in your blood pressure log in addition to the ones mentioned above.

  • electrolytes (salt, potassium, magnesium, calcium)
  • calorie types (carbs, fats, protein)
  • total calories
  • water (measure hydration)
  • simple sugars


Analyzing your Blood Pressure Data

So you’ve got a spreadsheet full of data, what can you do with it? The quickest thing to do after you’ve acquired data for a reasonable span of time is to sort the data by systolic pressure measurements. Then review the top 10 or 20 entries and look for similarities between rows. Is there a correlation between stress levels and your blood pressure readings? Make some adjustments to your life to reduce stress.  Meditation and exercise are both great ways to calm yourself each day.

Other benefits to keeping this log is that it’ll make you more aware of what you’re putting in your body and the environmental stresses that you’re under.

  • How much are you smoking?
  • How much are you eating each day?
  • Do you drink enough water?
  • Does your alcohol/nicotine use go up during times of stress?
  • How much are you actually exercising?
  • What days of the week are you feeling the most stressed?

Depending how detailed you keep your log, you can glean a lot of information about yourself.  You might notice a lot of habits that you never realized you had.
A sure fire way to mitigate some bad low blood pressure habits is to adopt some high efficiency lifestyle changes.
