The potassium in soybeans is also interesting to compare because although it’s potassium density (mg of potassium for every calorie) places it midway in the rankings, it’s potassium by weight (mg of potassium for every 100g of food) is the highest. White beans are the most potassium dense bean! What does that mean?
Though bananas are lauded for their potassium content, one cup (179 grams) of any of these beans has twice as much potassium as one banana. One cup of cooked white beans gives you 829 mg of potassium — a whopping 18% of the AI ( 1, 3, 12 ).
Do bananas have more potassium than beans?
Although bananas are a great source of potassium, many other healthy foods — such as sweet potatoes and beets — have more potassium per serving. Some foods such as Swiss chard and white beans even have double the amount of potassium per cup, compared to a medium-sized banana.
Which legumes contain the most potassium?
As for legumes, beans and soya beans contain the most potassium (and are the ones with the most amount of calories). On the other hand, in this ranking you can see that green beans and peas have a low quantity of calories per 100 grams.
Beans are unique among good sources of potassium because they also provide plenty of high-quality protein. Not surprisingly, in the Adventist Health Study-2, a large epidemiologic study involving more than 33,000 people, those who ate the most beans and foods made from plant proteins were the least likely to suffer a hip fracture.
Do beans fix nitrogen?
Some legumes are better at fixing nitrogen than others. Common beans are poor fixers (less than 50 lb N per acre) and fix less than their nitrogen needs. Maximum economic yield for beans in New Mexico requires an additional 30–50 lb of fertilizer nitrogen per acre.
Are legumes a good source of nitrogen for the garden?
Legumes (peas, vetches, clovers, beans and others) grow in a symbiotic relationship with soil-dwelling bacteria. The bacteria take gaseous nitrogen from the air in the soil and feed this nitrogen to the legumes; in exchange the plant provides carbohydrates to the bacteria.
What is a good nitrogen fixer for plants?
Other grain legumes, such as peanuts, cowpeas, soybeans, and fava beans, are good nitrogen fixers and will fix all of their nitrogen needs other than that absorbed from the soil. These legumes may fix up to 250 lb of nitrogen per acre and are not usually fertilized (Walley et al, 1996; Cash et al, 1981).
