What Is Tempeh?
Tempeh is a traditional fermented food from Indonesia. It is made of any kind of soybeans bound tightly together by fermenting them with a special fungus called Rhizopus oligosporus. It is a fragrant fungal species that adds to the taste and the overall nutrition of soybeans. The traditional method of preparing tempeh involves introducing the fungus into the soybeans and wrapping the mixture with banana leaves. These packages are then incubated at 30 to 31°C for about 24 hours, which binds the soybeans together (1). After the incubation period, tempeh is ready to be packed and sold. Tempeh is not considered a processed food because of this natural process. Pure, original tempeh gives off a nutty and dry flavor with an earthy undertone. There are various types of tempeh based on the ingredients added (apart from soybeans) that enhance the flavor of the end product. The most common additives are flax seeds, oatmeal, cassava fibers, and peanut dregs. The more exotic ones are grated pumpkin and coconut dregs, but the latter could cause food poisoning as coconut dregs could get contaminated with other unwanted microbes. Given its nutrient profile, tempeh can be called a superfood. Keep reading to find out why.
Nutritional Profile Of Tempeh
Tempeh (100 grams) contains the following nutrients (2): Apart from these, tempeh also has various forms of vitamin B, including folate, riboflavin, thiamin, and pantothenic acid. In addition, it also has other essential minerals (iron, manganese, copper, and zinc) in trace amounts. Rachel Dyckman, Owner and RD at Rachel Dyckman Nutrition LLC, says, “Tempeh is an excellent source of complete plant-based protein and can help those who are vegan or vegetarian to meet their protein requirements.” How exactly do these nutrients in tempeh contribute to the body’s healthy upkeep?

6 Health Benefits Of Tempeh
Kristin Gillespie, MS, RD, LD, advisor for Exercisewithstyle.com, says, “One serving of tempeh is a 3-oz portion. Tempeh can certainly be added to your daily diet at 1-2 servings per day.” Tempeh may immensely benefit your health in the following ways.
1. May Boost Growth Of Gut Flora
The fermentation of soybeans with a few fungal strains causes the breakdown of phytic acid (an antinutrient that prevents the absorption of nutrients into the body). This helps promote digestion and gut flora health. Tempeh can be a probiotic (3),(4). Tempeh has also shown prebiotic properties, which again promote gut flora by stimulating the growth of bacteria like Bifidobacterium and Lactobacillus (5). This helps improve gut health and prevent related diseases.
2. May Help Maintain Bone Health
Tempeh is rich in calcium, an essential element that is not produced in the body. Hundred grams of tempeh can contribute to at least 10% of your daily recommended calcium intake. Calcium deficiency may affect bone density negatively. This, coupled with oxidative stress, may cause osteoporosis (weak and brittle bones) (6).On the other hand, children need calcium for proper skeletal growth (7). A study involving 1793 Italian adults struggling with osteoporosis examined the relationship between dietary calcium intake and bone mineral density (BMD). Of the patients who had low BMD and major fragility fracture, 30.3% had an inadequate dietary calcium intake (3. May Reduce Oxidative Stress Tempeh has isoflavones, an antioxidant abundant in soybeans. Many studies suggest that isoflavones inhibit free radical damage and reduce oxidative stress on the cells (8). The isoflavone activity is especially important in postmenopausal women as they are at a higher risk of cardiovascular disease and cancer (9),(10). In a study, postmenopausal women on a soy-rich diet experienced a significant reduction in oxidative stress (11). Another study suggests that soy isoflavones may help reduce liver damage in mice (12). Kristin Gillespie says, “This, in turn, may help prevent many chronic illnesses and damage to vital organs, including eyes and skin.”
4. May Improve Heart Health
Isoflavones in tempeh work against bad cholesterol in the body. They were found to reduce LDL (bad) and total cholesterol levels in the bloodstream (13). Moreover, this effect was more pronounced in subjects with hypercholesterolemia (high blood cholesterol). The cholesterol-lowering effect of isoflavones and their antioxidant properties may also help reduce the risk of cardiovascular disease, including heart blockages (14). Besides, a study on mice also concluded that tempeh itself may decrease cholesterol levels besides exerting hepatoprotective (liver-protective) properties (15).
5. May Help Manage Weight
The protein in tempeh makes you feel fuller for longer as it can take a while to digest. This increased satiety can keep you from overeating and helps control energy intake. This way, tempeh is a better option than tofu, another soy-based product. While one serving of tofu (100grams) gives only about 8g of protein, the same quantity of tempeh provides 19g of the nutrient. However, you must keep various tofu benefits in mind while making the comparison, including its versatility and ability to absorb flavors well, making it a favorite in various cuisines. A study suggests that reducing the carbohydrate intake and replacing it with proteins may improve the body’s thermogenesis (heat production), which may help reduce body fat (16). However, more long-term studies are needed in this regard.
6. May Reduce Cancer Risk
Isoflavones are phytoestrogens that play a key role in the prevention and treatment of cancer. Genistein, an active isoflavone in soybeans, targets processes involved in cancer formation (17). Another study suggests that genistein and daidzein (also an isoflavone) may help prevent breast and prostate cancers by inducing apoptosis (programmed death of cancer cells) (18). You can reduce the risk of chronic diseases by consuming tempeh. But is it safe for everyone? Let us find out.
Who Is Tempeh Safe For?
Tempeh is safe for people of all age groups except those with soy allergies. Besides, individuals with compromised thyroid function and whose iodine intake is insufficient may also risk developing hypothyroidism after soy food intake. Hence, such individuals should consult their doctor before including tempeh in their diet (19). Can you eat tempeh directly, or does it have to be cooked? Here are a few things you should keep in mind.
How To Use Tempeh?
Tempeh must be cooked either by boiling, frying, or steaming after being seasoned and broken down. You cannot consume uncooked or undone tempeh as it does not contain any active nutrients and might be harmful. Tempeh usually takes just about 10 to 20 minutes to be fully cooked, irrespective of the process used. Frying or sauteing tempeh makes the outer layer brown and crunchy and the inner layers soft and chewy. Shelly, a blogger, shared her experience about preparing and consuming tempeh in her blog. She said, “Now, tempeh isn’t processed in the same way soymilk, tofu and prepared convenience foods are. Tempeh is a whole food. I feel confident in eating a few ounces of tempeh a day (i).” She added, “Many recipes use tempeh that has been chopped or crumbled but the way I use it most often is in bacon form! I can place the bacon strips on a sandwich or crumble it on a salad or chop it into various dishes.” There are many tempeh dishes you can try making.
