Soy Milk Chemical Constituents

Soy milk is rich in isoflavones and proteins and it also has a wide range of phytochemicals which includes phytic acid, sterols and saponins.


Isoflavones are a class of phytochemicals called phytoestrogen. The main isoflavones present in soybeans are genistein, daidzein and glycitein. Plants produce isoflavones when they experience environmental stress such as infection and nutrient deficiency. Many plants contain isoflavones but it is found in highest amount in soy.


Soybeans are rich in unsaturated fatty acid especially linoleic acid. Oil extracted from soybeans is composed of 54% of linoleic acid, 24% of oleic acid and 11% of palmitic acid. The high amounts of poly unsaturated fatty acid present in soy helps reduce inflammation.


Among plant based proteins, soy protein is considered to be one of the high quality proteins. The protein content of soybean varies between 36% and 46% depending on the variety. If vegetarians and vegans include soy based products regularly in  moderate amounts in their diet, it will greatly help meet their daily protein requirements.

1. Cardiovascular Benefits

Consuming soy protein regularly has a protective effect and greatly helps reduce LDL cholesterol. It has been proven in almost 38 studies that intake of 47 gram of soy protein reduce total cholesterol by 9.3%, LDL cholesterol by 12.9% and triglycerides by 10.5%. The important point to note is whole soy foods like soy milk produced the best results when compared to processed soy foods. This is due to the high amount of fiber, protein and isoflavones present in soybeans.

2.  Anticancer Properties

In a study done on 73000 Chinese women, there was a significant correlation between high whole soy food intake and reduced risk of premenopausal cancer risk. Also consuming whole soya products  during adolescence regularly reduced the risk of breast cancer in later years and you can read the study that supports this claim here. Anticancer effect is due to the presence of high amounts of isoflavones. Soy based products also has a positive effect on prostate cancer.

3. Good For Menopausal Women

The isoflavones in soy milk is a phytoestrogen meaning they can activate estrogen receptors. Though it cannot activate estrogen receptors like a real estrogen, it does have a significant effect. Consuming soy products including soy milk is associated with reduced risk of developing breast cancer in menopausal women and also reduced mortality rate among women suffering from breast cancer.

Consuming soy products also reduces menopausal symptoms especially hot flushes. However when pre menopausal women consume soy products, it reduces follicle stimulating hormone and luteinizing hormone which results in increasing menstrual cycle length and the effect of this delay in menstrual cycle on our health is not known. Soy milk is rich in calcium and protein so it helps preserve density in menopausal women.

4. Aids Weight Loss

Soy protein has beneficial effects on obesity. Consuming soy protein increases satiety, reduces excess body fat and improves insulin resistance. Soy protein also reduces fat accumulation in liver and adipose tissue thus preventing liver problems. Since soy is rich in protein, consuming a cup of soy milk will keep us satiated for a long time. If you are on a weight loss diet, try including soy milk in your weight loss diet regularly.

Since soy is rich in isoflavones which are phytoestrogens, men are usually advised to stop consuming soy foods in excess as it can reduce testosterone levels, interfere with fertility, have feminizing properties and erectile dysfunction but this only happens when soy is consumed in excess and not when soy was consumed in moderation. Consuming large amounts of soy isoflavones have a negative impact on fertility in women so try to have soy milk in moderation.

Also introducing soy products to female babies before 4 months increases the risk of getting menstrual periods early by 25% so never give soy milk products to babies younger than 4 months and even for babies below 2 years give soy products only in moderation. There are information that soy increases the risk of getting thyroid disease but this has been proven not to be true and it is the same for soy increasing the risk of getting certain cancers too.

    Can you please post solutions for the current health situation regarding kirimigals etc?
    I am surprised nothing has appeared on the blog. However I did see the two videos on vasambu bracelet and thirikadugam. But i never saw anyone adding tulasi and manjil to that drink.

    This blog was specifically started to address this matter originally. Now the blog has changed to western food trends.

    Basically in terms of prevention and daily meals what can we do to cultivate ETHIRPU SHAKTI….?

    I am surprised given the current situation there is very limited information and videos in Tamil Nadu that can present sensible information and can give day to day cooking suggestions…Taking delonga coffee, home made pizza and the one kashayam usually made wrong (boiling in aluminum vessel which will ruin the kashayam) is not making any logical sense! Listing some random vague fruits and vegetables doesn’t help either. I am writing about the current information I have come across on you tube….

    Health is an all encompassing lifestyle not a series of good and bad habits that cancel each other out. Whatever bad you do cancels out the good you try to do! Drinking kashayam and then taking coffee afterwards makes no sense don’t even bother with the kashayam then….

    (sorry dalonga coffee, I don’t drink coffee so I don’t know) it says since people can’t come out of the house they are making this coffee at home instead since the situation started! so in response to the situation people increased their coffee making? why not make traditional foods that boost the immune system? coffee and tea decreases our immunity and doesn’t help in this situation! and it will make reduce effectiveness of remedies.

    it would be good if people stayed home and NOT come out after the AGNI NATCHATHIRAM so the SUN can purify the atmosphere….it will end May 28th I think. its not bad you are home, let nature purify the atmosphere with the SUN!

    AGAIN please don’t come out until the Agni Natchathiram is over. You can keep anything you want to purify outside and let the sun’s rays purify it.

    Even vehicles can be kept out instead of sprayed with chemicals which are not good to inhale. Please minimize dust and air pollution (indoor and outdoor) as much as possible. Try to burn only things that burn fully clean and not become sooty. And avoid spraying harsh chemicals that could irritate the lungs. The SUN IS THE SAFEST METHOD TO PURIFY. Sun is most powerful at NOON especially.

    With vehicles off the road it can help REDUCE AIR POLLUTION and help the SUN to purify the atmosphere THIS AGNI NATCAHTHIRAM WHICH ENDS MAY 28TH.
