The soya bean plant is native to China, where it has been farmed for more than 13,000 years. It is a member of the legume family. The soya bean (Glycine max) is similar to other beans in that it grows in pods that contain edible seeds. They are often green in colour, although they may also be yellow, brown, or black in appearance. Because of the bean's flexible texture, it may be transformed into a range of meals such as "milk" and soy protein, as well as tofu, miso, and tempeh. When eaten fresh from the pod, soybeans are referred to as edamame beans, which is short for edamame bean.

1. A source of antioxidants that are protective
Isoflavones are naturally occurring chemicals found in soybeans. These polyphenols are potent antioxidants, and as a result, they assist to reduce the damage caused by molecules known as free radicals, which is referred to as oxidative stress. It is this oxidative stress that has a role in both the ageing process and the development of chronic illness. Soybeans are particularly high in isoflavones, and they also include other biologically active plant components such as saponins.
2. It has the potential to reduce menopausal symptoms
Daidzein and genistein, which are isoflavones found in soy, have gained a great lot of attention in recent years, with some studies suggesting that some women who consume a high-soya diet may have a decreased risk of breast cancer. This is due in part to the fact that isoflavones are classified as phyto-oestrogens, which means that they act in the body as a weak version of the hormone oestrogen. Several ladies have said that this has helped them with peri-menopausal symptoms such as depression and hot flushes.
In order to determine if a diet high in phyto-estrogenic foods is helpful for all women, we must first understand how our bodies respond to various meals. Genetics, gut flora, and environmental variables all play a role in how our bodies react to certain foods.
3. A source of plant protein that is "complete."
Soya beans are a good source of plant protein because they include all nine of the necessary amino acids that our bodies need for development, repair, and other processes such as immunity. The digestibility of soy protein, which relates to how efficiently our bodies can absorb and use the protein, is excellent, with some studies showing that it may even be equivalent to the digestion of animal protein.
4. It has the potential to improve heart health
Soybeans also contain chemicals known as phytosterols, which are beneficial to the body. These plant chemicals have a structural similarity to cholesterol and function in the body by blocking the absorption of cholesterols (cholesterol metabolites). This explains why consuming foods like soy on a daily basis has been linked to lower levels of cholesterol in the blood. According to studies, this includes a decrease in low-density lipoprotein (LDL), the form of cholesterol that is often referred to as 'bad' cholesterol, as well as a decrease in total cholesterol.
Regular eating of legumes, particularly soya beans, has also been related to a decreased risk of heart disease; this is assumed to be due to the high concentration of phytochemicals and fibre found in legumes.
5. It may be beneficial to bone health
The addition of soya foods in a mid-life woman's diet may be advantageous since reduced levels of oestrogen after menopause may lead to a larger decline in calcium levels in the bones. According to some research, consuming 40-110mg of soy isoflavones per day may help to slow bone loss and increase bone mineral density in the long term. According to the numbers, this is the equivalent to eating 140-440g of tofu or 35-100g of cooked soya beans per day on a practical level.
Is soy safe for everyone to consume?
Soy is typically considered to be harmless for the majority of individuals, unless they have a soy allergy, in which case they should avoid it. Soybeans are also regarded to be goitrogenic, which indicates that they have the potential to interfere with the function of the thyroid gland. Despite the fact that this impact is low in reality, if you have thyroid disease, you may want to limit your consumption.
Oxalate is present in soy products; thus, persons who have a history of calcium oxalate kidney stones may want to avoid ingesting too many soy products. Researchers believe that soy products containing a little quantity of calcium and moderate quantities of phytates may potentially be beneficial for kidney stone sufferers, according to recent research.
The intake of soy has been more contentious in recent years, with some animal studies indicating a relationship with various diseases (including breast cancer). The European Food Safety Authority has established that soy isoflavones do not have a negative effect on the thyroid, breast, or uterine in postmenopausal women, which lends credence to the food's nutritional value.
Trypsin inhibitors and phytates are among the antinutrients found in soya, and these substances may interfere with our ability to absorb some of the bean's beneficial elements. Traditionally produced soya products, such as tempeh and miso, have higher nutritional value since they have been soaked or fermented before cooking, reducing the amount of these chemicals in the soybeans before cooking.
