Think Your Diet Is Paleo? Not If Your Potassium Intake Is Less Than…

The stereotype about the Paleo diet is that it is meat heavy. How much meat Paleo era-eaters ate is debatable, but that they consumed large amounts of potassium rich, plant-based foods is not! When examining 159 Stone Age diets, the average daily potassium intake has been reported to be 400 meq/day (Sebastian et al. 2006), as shown below:


How much is 400 meq in milligrams (mg) of potassium? 1 meq = 39.1 mg of potassium, so to figure that out we multiply 400 *39.1, thereby yielding an average daily potassium intake of 15,640 mg/day! It’s important to note that this value is based on a 3000 calorie diet (Eaton et al. 1997). Dividing 15,640/3000 yields 5.21 mg potassium/calorie.

In contrast, as studied in 12,581 US adults, the average dietary potassium intake has been reported to be only ~2600 mg/day (Cogswell et al. 2012). Furthermore, only 1.4% of all subjects had potassium values greater than 4700 mg/day!

What’s my potassium intake? Shown below is my 7-day average intake from 8/29/2015-9/4/2015. The black rectangle in the lower right corner shows my average daily potassium intake to be 10,383 mg/day.

my potass

My average daily calorie intake during that week was 2193. In terms of mg potassium/calorie, my value is 4.73 (10,383/2193), which isn’t far from the reported average Paleo value. What’s yours?

For reference, shown below is a representative day during that week (Wednesday, September 2; 2251 calories) for what I ate.

Broccoli vs Protein Bars

Do you eat protein bars and think that they’re a great protein source? Sure, they are. But is there a healthier way to get that protein into your diet?

In Table 1 I compared the macronutrient composition and, dietary fiber, sodium and potassium content of 2 popular protein bars, Met-Rx and Pure Protein with broccoli. That’s right, I said broccoli.

Met-Rx Pure Protein Broccoli
Size 1 Bar (85g) 1 Bar (78g) 2 lbs (900g)
Calories 310 300 306
Protein 32g 31g 25g
Fiber 2g 3g 23g
Sodium 200 mg 190mg 300mg
Potassium 160 mg 65mg 2840mg

One 3 oz. bar contains approximately 300 calories. In contrast, to get the same amount of calories, you can eat ~11x more food, 32 oz. (2 pounds) of broccoli!. One can make the counterargument that it’s difficult to eat 2 lbs. of broccoli. It’s not, and I eat a 2 pound broccoli meal 1-2x/week. What’s easier to do is eat a protein bar, not be full, and overeat! It’s much harder to overeat, in contrast, eating that much broccoli.

Next, eating that broccoli meal yields 8-11x more dietary fiber, for the same amount of calories. Dietary fiber feeds your gut bacteria, which may be involved in mechanisms underlying lifespan. Separately, broccoli’s potassium/sodum ratio is ~9.5, in comparison with less than 1 for both protein bars. An elevated potassium/sodium ratio is associated with reduced blood pressure (Zhang et al. 2013), which is a known risk factor for stroke and heart disease (Lawes et al. 2008).

Sure, it’s 2 lbs of broccoli, but are you really full after a 5-bite protein bar?
