I soaked some dry kidney beans a few weeks ago to get them ready for some chili. To ensure the beans wouldn’t make us ill, my sister advised me to boil them before adding them to the chili. I did, but was that really necessary?.
You’ve got a knowledgeable sister. Many people are unaware of the danger that uncooked dry red kidney beans pose.
Not bacteria, but a substance known as “phytohaemagglutinin,” also known as PHA or kidney bean lectin, is the issue. Lectin is a type of protein that is used by both plants and animals for a variety of purposes. But this particular lectin, along with others, can be toxic in high doses.
You’ll regret it if this lectin isn’t thoroughly cooked out. According to the U. S. According to the Food and Drug Administration’s “Bad Bug Book,” consuming just four or five improperly cooked red kidney beans can result in severe vomiting and diarrhea within a few hours.
Although some cases necessitated hospitalization, most people experience relief within three to four hours of the onset of symptoms. Authorities believe there aren’t many cases of this specific foodborne illness in the U.S. because of this, in part. S. People typically start to feel better right around the time they might consider seeing a doctor.
PHA is present in other types of beans as well, but red kidney beans have the highest concentration. For instance, the toxin’s measurement unit is referred to as a “hemagglutinating unit” (hau). When fully cooked, red kidney beans have 200 to 400 hau, which is not enough to cause a problem. Raw red kidney beans can have anywhere between 20,000 and 70,000 hau. Only about one-third as much toxin as red kidney beans is present in white kidney beans, also known as cannellini beans. Only 5 to 10% of the nutrients in red kidney beans are present in broad beans, also known as fava beans.
How to Safely Cook Dried Red Kidney Beans & Cannellini Beans
1. The dried beans should be soaked for at least five hours or overnight.
2. Put the soaked beans in a big pot after being drained. Add enough fresh water to cover them by 2 inches. Bring to a boil. Boil the beans for 30 minutes.
3. Drain the beans and use in your slow cooker recipe.
Continue eating beans as usual, but remember to boil dried red kidney and cannellini beans for 10 minutes first before moving on to the intended preparation. When preparing food in a slow cooker, this additional step is required because most slow cookers only heat food to a temperature of 212°F. The beans will be cleaned of lectin during the 30-minute boil because lectin can temporarily upset the stomach.
Beans are cheap, wholesome, and delicious, especially when purchased dried. So use up some of your supply of beans by preparing one of these simple dishes that feature dried beans.

About 6 cups of cooked beans result from 1 pound (2 cups) of dry edible beans. If a 15-ounce can of beans is required for your recipe, use 1 75 cups of cooked beans, drained. Dry beans are cooked in two steps: soaking and cooking.
The actual “hands-on” time can be just minutes if you plan ahead for a time to soak the beans and a time to cook them if you’ve avoided cooking dry beans from scratch because “it takes too long.”
Cooking the beans makes them edible and digestible. If you want to eat beans later, store them in shallow containers in the refrigerator or use cooked beans in your favorite recipes. Freeze any extra beans within 4 days after cooking them. Beans can be prepared on the stovetop or in a pressure cooker or multicooker.
By soaking, dried beans can absorb water, which starts to break down the starches that cause gastrointestinal discomfort. Beans are growing two to three times larger while they are soaking. (Note: You don’t need to soak lentils, split peas, or black-eyed peas. ).
Do I Need To Soak Kidney Beans For Chili?
The beans don’t need to be cooked before being added to the chili in the pressure cooker, but I do suggest soaking them first. They are easier to digest once they have finished cooking, so it is not difficult to eat them after they have done so. The process only takes a little more effort.
