What is Soy Milk?
Soy milk is a plant-based milk alternative made from soaked, ground and strained soybeans. It has a creamy, nutty flavor and can be used as a substitute for dairy milk in drinks, smoothies, cereals and baking.
Soy milk is naturally lactose-free making it suitable for those with dairy allergies or sensitivities. It comes in different flavors including plain, vanilla, chocolate and unsweetened.
Compared to cow's milk, soy milk has a similar consistency but contains more protein and fiber and is cholesterol-free.

Benefits of Drinking Soy Milk
Here are some of the top evidence-based health benefits of drinking soy milk:
High in Nutrients
Soy milk has an impressive nutritional profile. Just one serving provides protein, fiber, calcium, vitamins and minerals.
Lactose-Free
Soy milk is naturally lactose-free making it a safe, nutritious milk alternative for those with lactose intolerance.
Heart Healthy
The unsaturated fats and lack of cholesterol in soy milk support cardiovascular health and may reduce heart disease risk.
Cancer Fighting
Compounds in soy milk called isoflavones have antioxidant properties that may help prevent certain cancers.
Relieves Menopause Symptoms
Isoflavones act like mild estrogens that can reduce hot flashes and other menopausal symptoms.
Promotes Bone Health
The calcium and vitamin D in fortified soy milk helps maintain strong, healthy bones and teeth.
Environmentally Sustainable
Soy milk has a lower environmental impact than dairy milk and is more sustainable long-term.
Risks and Side Effects of Soy Milk
Soy milk is safe for most people but there are some potential downsides to be aware of:
Allergies
Those with soy allergies should avoid drinking soy milk due to the risk of an allergic reaction.
Thyroid Issues
High soy intake may impact thyroid function. Those with thyroid problems may want to moderate soy milk consumption.
GMOs
Much of the soy used to make soy milk is genetically modified. Choose organic soy milk to avoid GMOs.
Phytoestrogens
Soy contains estrogenic compounds that may disrupt hormones, especially at high intakes. Moderation is key.
Digestive Problems
Some people report bloating or gas when drinking soy milk. Discontinue use if any digestion issues occur.
As long as soy milk is consumed in moderation as part of a balanced diet, it is unlikely to cause major health issues for most individuals.
Does Soy Milk Cause Cancer?
There has been some concern over whether soy products like soy milk could be linked to cancer risk, especially breast cancer in women due to the phytoestrogens.
According to major health authorities, there is no convincing evidence that moderate soy intake causes cancer or increases cancer risk in humans.
Population studies show soy consumption is associated with lower rates of breast cancer. The isoflavones in soy milk may actually have a protective effect against cancer.
While excessive soy intake is possibly unsafe, the levels found in foods and beverages like soy milk are not considered harmful or carcinogenic.
How to Choose the Best Soy Milk
When shopping for soy milk, look for these signs of quality:
Unsweetened
Choose unsweetened soy milk to avoid added sugars. Sweeten it yourself if desired.
Fortified
Select fortified soy milk to get extra nutrients like calcium, vitamin D and vitamin B12.
Organic
USDA certified organic ensures the soybeans are not genetically engineered.
No Carrageenan
Avoid carrageenan which may cause digestive issues in some people.
Shelf Stable
Shelf stable, aseptic soy milk keeps longer unopened than refrigerated varieties.
Opt for plain, organic soy milk fortified with nutrients for the healthiest option. Shake well before using.
