Soybeans – Definition, Nutritional Facts, Benefits, and More

Soybeans Definition

Soybeans (Glycine max) are a kind of legume natural to eastern Asia. They are an essential component of Asian diets and consume for thousands of years.

Today, they are mostly grown in Asia and South and North America. In Asia, soybeans are often eaten entire, but heavily processed soy products are much more common in Western countries.

Numerous soy products are available, including soy flour, soy protein, tofu, soy milk, soy sauce, and soybean oil.

Soybeans cover antioxidants and phytonutrients that are linked to various health benefits. However, concerns raised about potential adverse effects.

This article tells you everything you essential to know about soybeans. We include products we think are useful for our booklovers. If you buy dead links on this page, we may earn a small commission. Here’s our process.

Nutrition Facts of Soybeans


Soybeans mainly compose of protein but also contain adequate amounts of carbs and fat.

The nutrition facts for 3.5 grains (100 grams) of boiled soybeans are:

Calories: 173;

Water: 63%;

Protein: 16.6 grams;

Carbs: 9.9 grams;

Sugar: 3 grams;

Fibre: 6 grams;

Fat: 9 grams;

Saturated: 1.3 grams;

Monounsaturated: 1.98 grams;

Polyunsaturated: 5.06 grams;

Omega-3: 0.6 grams;

Omega-6: 4.47 g.

1. Protein

  • Soybeans are among the most acceptable sources of plant-based protein. The protein content of soybeans is 36–56% of the dry heaviness.
  • And also, one cup (172 grams) of boiled soybeans boasts about 29 grams of protein.
  • The nutritional value of soy protein is decent, although the quality is not as high as animal protein.
  • The main kinds of protein in soybeans are glycinin and conglycinin, which make up approximately 80% of the whole protein content. These proteins may trigger allergic responses in some people.
  • Its consumption of soy protein link with a modest reduction in cholesterol levels.

2. Fat

  • Soybeans classified as oilseeds and used to make soybean oil.
  • The fat content is about 18% of the dry weight. It mainly polyunsaturated and monounsaturated fatty acids, with minor amounts of saturated fat.
  • And also, the predominant kind of fat in soybeans is linoleic acid, secretarial for approximately 50% of the total fat content.

3. Carbs

  • It is low in carbs; whole soybeans are very low on the glycemic index (GI), which affects the increase in blood sugar after a meal.
  • This low GI makes soybeans appropriate for people with diabetes.

4. Fibre

  • Soybeans contain a fair quantity of both soluble and insoluble fibre.
  • The insoluble fibres are mostly alpha-galactosides, which may reason flatulence and diarrhoea in sensitive individuals.
  • Alpha-galactosides fit a class of fibres called FODMAPs, which may exacerbate irritable bowel syndrome symptoms (IBS).
  • Despite causing unpleasant side effects in some individuals, soluble fibres in soybeans generally consider healthy.
  • They fermented by bacteria in your colon, critical to forming short-chain fatty acids (SCFAs), which may recover gut health and reduce your risk of colon cancer.

Health Benefits of Soybeans


Like most whole foods, soybeans have some beneficial health effects.

1. May Reduce Cancer Risk

  • Cancer is a single of the foremost causes of death in modern society.
  • And also, eating soy products link to augmented breast tissue in women hypothetically increasing breast cancer risk.
  • However, most observational studies designate that consumption of soy products may lessen breast cancer danger.
  • Studies also indicate a protective effect in contradiction of prostate cancer in men.
  • Some soybean mixes — including isoflavones and Lunasin — may be responsible for the potential cancer-preventive effects.
  • Experience with isoflavones early in life may be incredibly protective against breast cancer later in life.
  • Keep in mind that this evidence limit to observational studies, which indicate an association between soy ingesting and cancer prevention — but do not show action.

2. Alleviation of Menopause Symptoms

  • MAnd also, menopause is the period in a woman’s lifetime once menstruation stops.
  • It often associates with unpleasant symptoms — such as sweating, hot flashes, and mood swings — which are brought about by reducing estrogen levels.
  • Interestingly, Asian women — particularly Japanese women — are less likely to knowledge menopause signs than Western women.
  • Dietary habits, such as the advanced consumption of soy foods in Asia, may explain this difference.
  • Studies show that isoflavones, a family of phytoestrogens found in soybeans, may alleviate these symptoms.
  • Soy products do not move all women in this method. Soy only appears to be effective in so-called equol producers — those who own a type of gut bacteria can convert isoflavones into equol.
  • And also, equol may be responsible for numerous of soy’s health benefits.
  • Daily eating of 135 mg of isoflavones for one week — equivalent to 2.4 ounces (68 grams) of soybeans per day — abridged menopausal symptoms only in equol producers.
  • While hormonal therapies have traditionally used as a treatment for menopausal symptoms, isoflavone supplements widely use today.

3. Bone Health

  • Osteoporosis characterizes by reduced bone density and an increased risk of fractures, especially in older women.
  • Consumption of soy products may decrease the risk of osteoporosis in women who have undergone menopause.
  • And also, these beneficial effects seem to produce by isoflavones.

4. Concerns and Adverse Effects

  • Even though soybeans have some health benefits, some individuals need to limit their soy products consumption — or avoid them altogether.

5. Suppression of Thyroid Function

  • High intake of soy products may overpower thyroid function in some people and contribute to hypothyroidism — a disorder characterized by low thyroid hormones production.
  • The thyroid is a large gland that controls growth and panels the rate at which your body expends energy.
  • Animal and human studies designate that the isoflavones originate in soybeans may suppress the formation of thyroid hormones.
  • And also, eating 1 ounce (30 grams) of soybeans each day for three months caused suppressed thyroid function symptoms.
  • The symptoms comprised discomfort, sleepiness, constipation, and thyroid enlargement — all of which vanished after the study over.
  • Another study in adults with slight hypothyroidism found that taking 16 mg of isoflavones every day for two months suppressed thyroid function in 10% of the participants.
  • The number of isoflavones consumed was relatively small — equivalent to eating 0.3 ounces (8 grams) of soybeans per day.
  • However, most healthy adults have not found any significant links between soy consumption and thyroid function alterations.
  • And also, soybean consumption on healthy adults’ thyroid function, whereas infants born with thyroid hormone deficiency were considered at risk.
  • In short, regular consumption of soy crops or isoflavone supplements. It may lead to hypothyroidism in sensitive individuals, especially those with an underactive thyroid gland.

6. Flatulence and Diarrhea

  • Like most other beans, soybeans contain insoluble fibres, which may cause flatulence and diarrhoea in sensitive individuals.
  • Although not corrupt, these side effects can be unfriendly.
  • Belonging to a fibre class called FODMAPs, the fibres raffinose and stachyose may worsen IBS symptoms, a common digestive disorder.
  • If you have IBS, avoiding or warning the consumption of soybeans may be a good idea.

7. Soy Allergy

  • Food allergy is a common disorder caused by a harmful immune reaction to specific components in foods.
  • And also, soy proteins trigger soy allergy — glycinin and conglycinin — found in most soy products.
  • Even though soybeans are among the most common allergenic foods, soy allergy is relatively uncommon in children and adults.


Soybeans are high in protein and a dressed basis of both carbs and fat.

They are a rich basis of various vitamins, minerals, and beneficial plant compounds, such as isoflavones.

For this reason, even soybean intake may alleviate the symptoms of menopause and reduce your risk of prostate and breast cancer.

However, they can cause digestive problems and overwhelm thyroid function in predisposed individuals.
