Potassium Foods During Pregnancy: Bananas, Potatoes, and Lentils
Compare potassium in bananas, baked potatoes, and lentils during pregnancy and understand the 2,900 mg adequate intake.
A single medium banana provides about 422mg, making bananas one of the richest everyday potassium sources in the Indian diet.

The short answer: Potassium comes from many foods, not just bananas. The NIH Office of Dietary Supplements lists an adequate intake (AI) of 2,900 mg a day for pregnant adults and 2,600 mg for pregnant teens. An AI is a population reference value, not a diagnosis or a target for every individual meal.
Compare three familiar foods
PregNut's USDA-based food data reports these potassium amounts per 100 g:
| Food | Potassium per 100 g | What the number describes |
|---|---|---|
| Raw banana | 358 mg | Edible banana, without peel. |
| Baked potato, flesh and skin | 535 mg | A baked potato eaten with its skin. |
| Boiled lentils | 369 mg | Cooked lentils, not dry seeds. |
A 150 g portion of the listed baked potato would provide about 803 mg; portion size and preparation change the result. Other sources include beans, spinach, tomatoes, milk, and yogurt. Use the food lookup to compare more options, and consider the whole day's food rather than trying to reach the AI with one item.
Do I need a potassium supplement?
Do not assume a higher potassium number is better for you. The NIH potassium fact sheet warns that potassium-containing salt substitutes can raise potassium too high for people with kidney disease or those taking certain medications. Ask your clinician before using a potassium supplement or salt substitute, especially if you have kidney disease or take medication that affects potassium. The food comparison above cannot assess your blood potassium level or individual needs.
