Is it safe to drink Soy Milk?

Yes, it is safe to drink soy milk in moderation. Hear what the dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women’s Hospital says. She says that soy milk is rich in polyunsaturated fats, fiber, vitamins, and minerals, and low in saturated fat. Natural soy products are the best for consumption in moderation.

One main thing that goes against soy milk is that it contains estrogen-like chemicals. High doses may lead to health issues. So, refrain from intake of soy isoflavone supplements. Also, the foods are made with textured vegetable protein and soy protein isolate.

The dietitian McManus says it is fine to eat whole soy foods such as soy milk, edamame, and tofu. But in moderation many times a week.

What is Soy Milk?

Soy milk protein is of high quality and complete protein. It has all the essential amino acids that your body cannot produce. Amino acids have the ability to prevent several health disorders.

For vegetarians and vegans, obtaining the required protein may be a challenge. Among all plant-based proteins, soy has high-quality protein for human consumption.

Certain studies complement soy protein for reducing Cardiovascular disease (CVD) risks. It is beyond lowering cholesterol levels in the blood.

Additionally, isoflavones substance is high in soy compared to other plant-based foods. A cup of soy milk (250ml) contains about 25g of Isoflavones. Isoflavones provide protection against age-related diseases including cardiovascular disease.

A PubMed study points out the hypotensive effect of soy protein. It reduces congenital heart disease (CHD) disease by 6 %.

3. Controls Blood Pressure

In general, high protein intake means it helps to lower blood pressure. That is why soy protein is hypotensive.

A study was carried out with 40 men and women taking 500ml of soy milk twice every day for three months. The study reveals that the intake of soy milk significantly lowers blood pressure. It is more than cow’s milk. See the figure below published by Oxford Academic on blood pressure comparing soy milk and cow milk.

4. Soy milk Improves Endothelial Functions

Endothelial is a thin membrane that forms inside blood vessels and the heart. Also, endothelial prevents blood clotting, supports vascular relaxation, and improves immune function.

According to a study that soybean isoflavones improve endothelial functions in postmenopausal women.

5. Soy Milk Improves Arterial Stiffness in Postmenopausal Women

Arterial Stiffness is related to where the artery wall is not able to function to its potential.
Soy milk isoflavones improve arterial stiffness in postmenopausal women.

6. Bone Health Through Soy Milk – Prevents Osteoporosis

The estrogen effects of isoflavones in soy milk provide skeletal benefits. This is specifically important for women following menopause. Women following their menopause tend to lose a substantial amount of bone mass. Due to the loss of estrogen levels in the body. It leads to the weakening of the bones and ends with a bone fracture.

A study in 2017 supports that soy helps to prevent bone mass loss. Thereby reducing the risks of bone fractures associated with osteoporosis.

7. Soy Milk Reduces Breast Cancer Risks

The occurrence of breast cancer is much lower in countries where high soy or soy milk is consumed. This effect is attributed to the chemopreventive effects of soy isoflavones.

A PubMed article says higher consumption of soy milk has a ⅓ reduction in breast cancer risks. Also, women eating soy food have a significant reduction in death and recurrence.

Another study shows a lifelong soy-rich food diet reduces the risks of breast cancer in women.

Advice from American Cancer Society Expert Marji McCullough, ScD, RD. The Strategic Director of Nutritional Epidemiology for the American Cancer Society. She says that soy foods are healthy and safe to eat or drink. But, not in favor of taking soy supplements that have high isoflavone concentrations.

8. Soy Milk Benefits in Kidney Functions

The link between soy milk and renal benefits has significant importance. This is because of the increasing number of diabetes patients around the world.

Soy milk protein is the key substance that helps to reduce stress on kidney functions. Drinking soy milk decreases the risk of developing renal diseases. Particularly in diabetes patients.

Soy milk has high-quality protein compared to animal-based proteins. So, it is advisable to replace animal-based protein with soy-based protein in your diet. Doing so gets you kidney function-related benefits. A study also establishes a good connection between soy and renoprotection.

9. Drinking Soy Milk Reduces Menopausal Symptoms

Women who drink soy milk may prevent or ease existing menopause-related hot splashes. It is the soy milk isoflavones that make a good effect on women.

Women may opt for soy isoflavone supplements to combat hot splashes. This is to be sure enough soybean isoflavone is taken to reduce menopausal symptoms.

10. Protein’s Role in Obesity

The high-quality soy milk protein helps in reducing the accumulation of body fat. It also reduces cholesterol levels and improves insulin resistance. Thus, soy protein is considered a hallmark of human obesity.

A Semantic Scholar study describes the benefits of soy protein against human obesity.
Consumption of soy protein affects satiety. Reduces excess body fat in obese animals and humans.

Studies further establish that soy milk is one of the greatest weight loss drinks that you can bank on.

11. Soy milk is an antidepressant

Soy milk helps in boosting your mood. This is because of the vitamin B6 and vitamin B complex in it. The rich magnesium in soy milk releases the serotonin hormone. It works as an antidepressant on your mind.

12. Is Soy Milk Good for Diabetics?

According to the nutrition scientists at the University of Massachusetts Amherst, the bioactive components of soy food are useful for Diabetics. The bioactive component is nothing but the isoflavones in soy milk.

Drinking soy milk reduces blood glucose and improves glucose tolerance, in diabetes patients.

13. Is Soy Milk Good for Babies and Toddlers?

Well, the answer is Yes and No.

The infant’s only food is always milk. So, the infant diet is 100% milk. The best milk for infants is none other than breast milk.

The infants fed with soy milk will have high exposure to the phytoestrogens of soy. Phytoestrogens produce estrogen-like effects in the body. Making infants vulnerable to similar effects of estrogens. Leading to health issues.

Therefore, soy milk may be ideal for babies over one year of age who are intolerant to lactose. Meaning that babies or toddlers are intolerant or allergic to cow’s milk.

Soy milk as a single source of nourishment does not have all the vital nutrients for a child’s growth, That is one of the main reasons why to avoid feeding infants soy milk under one year.

For example, soy milk is low in calcium. As you know calcium is vital for bones and teeth development. If you are feeding the child only soy milk then you need to add other sources of calcium to the diet.

Be aware, that some infants are allergic to soy milk. In which case completely avoid feeding them with soy milk.

A simple guideline for infants is:

  • Never feed infants soy milk under the age of one
  • Be aware, that soy milk lacks the nutrition needed for growth.
  • Remember soy milk can be only an addition to breast milk or cow’s milk in order to get the soy milk benefits.
  • Soy milk should not be a replacement for breast for cow’s milk

The best is to seek advice from your doctor about adding soy milk to the infant’s diet. Soy milk intake has to be in moderation and in the right quantities.

The high protein, iron, and other vitamins in soy milk are very useful for a child’s growth.

Soy Milk Benefits for Females

  • Protects against postmenopausal syndromes
  • Reduces the menopausal hot flash frequency and severity
  • Helps to lose weight
  • Strengthens blood vessels
  • Controls blood pressure
  • Improves endothelial functions
  • Soy milk improves arterial stiffness
  • Prevents osteoporosis

  • Reduced rate of mortality among women with breast cancer
  • Lowers risk of heart disease
  • Soy protein reduces the arterial low-density lipoprotein (LDL) concentration
  • Protect mental health
  • Improve immunity
  • Cures skin problems
  • Soy milk is an antidepressant

Side Effects from Soy Milk

Impact on thyroid functions: The phytoestrogen component of soy milk behaves like an estrogen hormone. Too much phytoestrogen intake may lead to thyroid problems. A study in 2018 on 40 people says 66mg of soy phytoestrogen a day may pose a risk of impaired thyroid functions.

Not suitable for pregnant mothers: High intake of soy milk may harm the development of the baby. Being moderate is the key. If you wish to take soy just be sure to take whole foods like soy milk.
