The following
blog is from my friend and fellow dietitian, Jaime.
"The topic of
potassium has been brought to my attention lately. Did you know that the
Adequate Intake level for potassium is 4700 mg for adults? Have you ever tracked your potassium intake
(probably not)? I hadn't until recently and I only average around 1000 - 2000
mg/d. And many days I average 7 - 9
servings of fruits/veg and I eat beans and nuts daily.
Low potassium is associated with a risk of high blood pressure, heart disease, stroke, arthritis, cancer, digestive disorders, and infertility.
I played around with some high potassium foods (nutritiondata.com is a great website to see the nutrient content of foods) and in order to ingest 4700 mg/d, here's an example of what I'd have to eat in ONE DAY:
1 medium banana
1 WHOLE avocado
1 cup black beans
1 large orange
1 cup shelled pistachios
1 whole mango
3 oz dark chocolate (60-69% cacao) - But 3 oz is A LOT, an entire bar
1 cup chopped kale
1 cup cherry tomatoes
= approximately 4700 mg potassium
More commonly consumed fruits (grapes, apples, strawberries, blueberries, raspberries, watermelon, only have around 100 mg per serving)
How many of you think you get enough potassium? I encourage you to track your intake to see how you're doing. There are some great apps that will calculate this for you (myfitnesspal or fitday).
PS, this post is not for persons with chronic kidney disease or for anyone who has been told they have had elevated potassium in the past - consult your doctor or dietitian."
