Pinto & White Beans 1
While many beans are high in potassium (including soy, kidney and lima), the best to have during pregnancy are pinto beans (which have 18 percent of your daily potassium intake per 1 cooked cup) and white beans (at 29 percent per cooked cup).
Avocados are an amazing source of good fats but, also, a great source of potassium. An average size avocado has about 28 percent of your daily potassium needs while a 1/2 cup of pureed avocado has about 16 percent.
Salmon & Other Fish 3
Although you should be VERY careful about eating raw fish during your pregnancy (check with your doctor!), one 3 oz. fillet of cooked salmon can provide you with 15 percent of your daily potassium. Other options are halibut (13 percent) and mackerel (10 percent).
Well, obviously I couldn't leave THIS one off the list! Yes, we all know that bananas are high in potassium. The average banana will give you about 12 percent of your daily potassium needs while 1 cup mashed actually goes up to a whopping 23 percent.
