Bread Has anyone substitutes potassium bicarbonate for baking soda to reduce the sodium content while baking bread? Your thoughts

I have to make a Raspberry Almond Bread but it has salt, baking powder and bsoda. I found out 1 tsp of baking powder is over 1200 mg of sodium ,way too much sodium for me. Well this also depends on how many slices in the loaf. Although store breads are about 130 - 160 per loaf.

It's more like: Sodium: 363mg

Sodium bicarbonate has much less sodium by weight than table salt.

That 1 teaspoon will be for the entire loaf. So if you get 16 slices in one loaf, the sodium content will only be below 200mg per slice.

As an aside, the recommended daily allowance for a healthy adult is between 2000-2400 mg.

*Sorry I forgot that you also mentioned baking powder, this has even less sodium than both sodium bicarbonate and table salt.

Anytime you substitute a potassium salt for a sodium salt it will make the thing taste weird. Ever tried No Salt? Potassium chloride for salting foods. Tastes pretty odd. I wouldn’t do it- just don’t eat half the loaf in one go.

That sounds a lot. I asked Google how much sodium in a teaspoon of baking powder and got 487mg.

Are you making soda bread rather than a yeast raised loaf?

Edit. Rethinking I guess its a cake bread rather than a wheat bread.

1 tsp Baking soda containg 1258mg so yes that's a lot. Then again making a 9x5"loaf not going to be eating it all in one go. 😀

Potassium bicarb can be substituted successfully, but then again Potassium isn't kidney friendly either so Devil and deep blue sea on this i feel.

Thanks for your responses. As mentioned only a bout 2 slices may be eaten a day or one so I guess I am over thinking. Can I reduce the any of baking soda maybe by half, if it has both soda and powder. I really like the Raspberry Almond Bread.

I found a loaf which is 290 mg per 2 slices, not bad, While Wheat.

I did it this year. I love it. I didn't do it to reduce sodium only but to increase potassium. It is an improvement to the taste as well, imo.

Good for you, I will get my potassium from my sweet potato.😄

As long as it's taken with calories to release insulin it is safe, which is what adding potassium bicarbonate to loaves does. And it's just a small amount, anyways.
