Tips for choosing the right soy milk powder for you

Minimized added sugar

Many soy milk brands include high amounts of added sugar. And check out for vanilla-flavored soy milk since they usually contain more than a tablespoon of added sugar per cup serving.

Avoid glyphosate residue

The majority of soy grown in North America is genetically changed to be herbicide-tolerant.

As a result, genetically arranged soy often has glyphosate residue. When the USDA verified crops for glyphosate residue in 2011, they found that 90% of all soybeans included residual glyphosate.

The protection of chronic, low-level exposure to glyphosate is not proven. Therefore, consuming organic or non-GMO soy is vital to minimize glyphosate residue intake.

No carrageenan

Carrageenan is a thickener made from red algae seaweed and widely used in processed foods. Carrageenan is the “generally regarded as safe” food additive by the FDA and WHO. However, a study links carrageenan to various inflammatory conditions, including inflammatory bowel disease.

In late 2016, the National Organic Standards Board voted to restrict the use of carrageenan in organic products. However, in 2018 the USDA decided not to implement the recommendation, and carrageenan is still allowed in organic products.

Minimal sodium

Sodium is present in almost any processed food, from salt to different food additives. Soymilk is not an exception.

Salt is added to enhance the flavor of non-dairy beverages. Additionally, gums and thickeners are added to improve the texture of the best soy milk powder in Japan containing sodium.

No gums and thickeners

Plant-based beverages usually contain gums and other thickeners to control separation and improve a drink’s texture. However, these gums and thickeners are positively processed, and they can sometimes cause gastrointestinal discomfort.

Typical gums and other thickeners in dairy-free milk are gellan gum and locust bean gum. Gellan gum is a polysaccharide and soluble dietary fibre. It is made following the process of bacterial fermentation of glucose or other carbon sources such as corn syrup, lactose, whey protein, or soybean extracts. 

Locust Bean Gum is a polysaccharide made from the seeds of the Carob Tree. Also called carob bean gum, locust Bean Gum is a soluble dietary fibre that is manufactured by intestinal microflora.

Benefits of using soy milk powder

Improves heart health

Soy Milk has protein, which is necessary for growth. Proteins are made of building blocks called amino acids.

They have a practical effect in controlling various health disorders. The amino acid and isoflavones content of soy protein may also help reduce LDL cholesterol.

Some analyses have shown that the intake of soy isoflavones can lower serum cholesterol levels in older adults.

Among people with type 2 diabetes, soymilk consumption is associated with normal blood pressure. Thus, the intake of soymilk can be a good way of improving cardiovascular health.

Promotes Weight Loss

Soy milk is naturally lesser in sugar content than regular milk. Cow’s milk has about 12 grams of sugar per cup, but only 7 grams are in soy milk.

A cup of whole soy milk has only 80 calories, equivalent to skim milk. In addition, the monounsaturated fatty acid in soy milk can hinder your intestinal absorption of fat, which is another great benefit for weight loss.

Drinking soy milk also provides you with an extra dose of fiber, keeping you feeling fuller for a longer time.

Brain Health

The best soy milk powder in Japan is rich in omega-3 fatty acids, called “healthy” fats that your body cannot produce on its own.

Omega-3 fatty acids are linked to a decreased risk of dementia and Alzheimer’s disease. Soy milk is still studied for its effect on these conditions, but soy, in general, is one of the finest non-animal sources of omega-3 fatty acids.

Prevents Postmenopausal Syndromes

During menopause, a woman’s biological estrogen production falls to a minimum. The sudden decrease in estrogen may create many health problems for postmenopausal women.

Postmenopausal women have greater risks of heart diseases, diabetes, and obesity. They are also more helpless to depression, mood swings, insomnia, and other psychological disturbances.

The phytoestrogen in soy is a perfect estrogen replacement. Regular soy consumption is an effective way to avert and alleviate these postmenopausal syndromes.

Strengthens blood vessel integrity

The omega-3 and omega-6 fatty acids and the powerful phyto-antioxidants in soy can protect your blood vessels from lesions and hemorrhage.

These combinations bind to the blood vessel lining and protect your lining cells from free radical attacks and cholesterol deposits.

The binding of these nutrients also enhances the fluidity and flexibility of your blood vessels so that they are much better resilient to blood pressure changes.

Prevents Osteoporosis

Osteoporosis is another age and hormone-related disease. The phytoestrogen in soy can help increase calcium absorption and prevent the loss of bone mass.

To reap health benefits, buy the best soy milk powder in Japan that contains extra calcium and vitamin D.

Side-effects of using Soy Milk Powder

While soy milk can be a beneficial alternative to dairy milk for those with lactose intolerance or dietary preferences, it’s essential to be aware of potential side effects associated with its consumption. Some individuals may experience digestive issues such as bloating, gas, or discomfort due to the presence of oligosaccharides, which can be difficult to digest for some people. Soy milk also contains phytoestrogens, plant compounds that mimic estrogen in the body. While moderate consumption is generally considered safe, excessive intake of phytoestrogens may potentially disrupt hormone balance in some individuals, particularly those with certain medical conditions or hormone-sensitive cancers.
