What Are Kidney Beans Sprouts?
Kidney bean sprouts are young shoots that grow when mature kidney beans are introduced to germination conditions such as moisture. Kidney bean sprouts have a yellowish to greenish color with spinny shoots. Upon sprouting the seed usually loses the old hull which can be removed by submerging the sprouts in a bowl of water and picking out the floating hulls.
Soaking kidney beans for 2 to 6 days will trigger the germination process, and young shoots will grow to form sprout kidney beans. The soaking process involves an initial soak, which takes 8 to 12 hours, followed by regular rinsing and draining every 12 hours for at least two days. Kidney sprouts grow relatively fast, and they are usually ready to harvest by the third day. Avoid growing kidney sprouts for longer than ten days as they will start to grow somewhat bitter leaves.
What Do Kidney Sprouts Taste Like?
While sprouting kidneys do have a robust flavor when cooked, the raw varieties are often considered to be bitter and with an unpleasant flavor. The bitterness is attributed to the presence of PHA, a naturally occurring chemical in the beans, which is toxic and must be denatured by boiling for at least 10 minutes.
What Is The Smell Of Sprouting Kidney Beans?
Sprouting kidney beans have an earthy smell that's significantly different from the almost smokey and sulfur smell of cooked kidney beans. The sprouting process leads to the breakdown of some of the chemicals responsible for this scent. However, beware that the seeds will become rancid if over soaked for too long.
How Long Does It Take Kidney Beans to Sprout?
Kidney beans will sprout by the second to fifth day after initial exposure to water followed by regular rinsing and drainage process. Kidney sprouts are usually ready to harvest in under a week after activation, but you can extend the growth time for a few more days. However, do not let them grow leaves, which are considerably more bitter.
Why Sprout Kidney Beans?
Reduce the Antinutrients - Dry kidney beans contain substantial amounts of PHA, which is an antinutrient, which are naturally occurring compounds that are produced by the plant to inhibit the consumption and absorption of nutrients from the raw seeds. The sprouting process makes the PHA toxin readily available for breakdown via cooking. This is why it's recommendable to cook kidney beans even after sprouting them.
Make Them Easier To Cook - The sprouting process leads to the absorption of water within the beans tissues, which makes them softer to cook. Sprouted kidney beans take much less time to prepare compared to dry kidney grains. The young sprout also develops tiny shoots that quickly cook away. The sprouting process involves the breakdown of the seed coat, which makes the interior much more comfortable to cook.
Increase In Health Benefits - The sprouting process increases the nutrient content in the seeds by tenfold; an 8 oz serving contains 8g of plant-based protein, which is critical for cell regeneration. The sprouting process also releases the stored nutrients making them more accessible to the digestive system.
Easy To Digest - Sprouted kidney beans have reduced amounts of antinutrients, making them much easier to digest. The growth of shoots and softening of the seed tissue (cotyledon) make it much easier to eliminate the remaining PHA toxins by 10 minutes of boiling. The absence of these toxins serves to reduce digestive discomforts that are commonly associated with consuming beans.
Increase In Fiber Content - The growth of shoots during the sprouting process leads to an increase in the amount of soluble fiber content in the sprout kidney beans. Soluble fiber goes a long way in supporting the ease of digestion and increasing healthy gut bio.
Health Benefits Of Sprouted Kidney Beans
1. Source of Plant-Based Protein
Sprouted kidney beans are rich in plant-based protein content. The increased protein uptake goes a long way in repairing body cells and increasing muscle density. However, it's important to note that plant-based protein is considered to be incomplete as it lacks some essential amino acids. These can, however, be substituted with other sprouts such as quinoa and buckwheat, which are more protein-dense. (Reference: link)
2. Reduced Calorie Content
The sprouting process leads to a reduction in the amount of calorie content as most of it gets broken down to provide energy, which is required for the germination process. Consuming kidney sprouts will, therefore, not have a drastic effect on the amount of blood sugar. The reduction in calorie content also plays a role in weight loss while also reducing the probability of developing heart disease. Most of the calorie content in kidney bean sprouts are in the form of starch, which releases energy slowly for a more extended period so you will be more energized and for longer. (Reference: link)
3. High Fiber Content
Sprouted kidney beans have increased soluble fiber content, which may contain amounts of resistant starch, which plays a significant role in weight management. The insoluble fiber eases stool passing and supports the growth of healthy probiotics within the digestive system. (Reference: link)
Do All Varieties Of Kidney Beans sprout?
Only raw mature kidney beans can sprout, pasteurized varieties and cooked or boiled beans will not sprout. This is because heat treatment usually denatures the enzymes responsible for the sprouting process.
Considerations When Buying Kidney Beans For Sprouting
Produced for Sprouting - While looking for dry kidney beans for sprouting, only go varieties which have been marked explicitly as sprout ready or sprout-able. These are varieties that have been specially produced and packaged for sprouting. Kidney seeds that have been produced for sprouting usually have an increased sprouting rate.
Brand - Already established brands are more likely to respond to customer feedback and have actual reviews. These play a significant role in deciding on the best product to get, it's recommended to go through the reviews before settling on a single product.
Source - The source of the seeds you plan to sprout will significantly determine the sprouting rate. This is due to storage and processing restrictions, which will affect the rate of germination. Look for varieties that are locally produced under FDA guidelines.

How to make raw Kidney Bean Sprouts edible for low Immunity Groups
Who's at Risk
1. Pregnant women: pregnancy usually leads to a reduction in the mother's immunity, making her prone to bacterial infection from the consumption of raw sprouts.
2. Children: children have a much weaker immunity as it's still developing during such years. Consuming contaminated sprouts can lead to infections in kids and should, therefore, be avoided.
3. Cancer Patients: cancer patients usually undergo treatment regimens, which can weaken the immune system such as chemotherapy. The patients should thus avoid raw sprouts as they might introduce harmful bacteria to the already compromised immune system.
4. Patients on Immunosuppressants: immunosuppressants are drugs that lower immunity. Consuming fresh sprouts while under immunosuppressant treatment can result in bacterial infection.
5. HIV & AIDS Patients: AIDS patients usually have weakened immune systems that are vulnerable to bacterial infection.
Boiling and Steam Method for Killing Bacteria
Wooden steam bucket (optional)
1. Halfway fill a large pot with water and bring to boil over medium heat
2. If you are boiling the sprouts: add the kidney bean sprouts into the pot of boiling water and allow them to boil for 20 minutes
If you are steaming: place the wooden steam bucket in the pot of boiling water and add the kidney bean sprouts into the bucket and cover it. Allow the sprouts to steam for 30 minutes
