Soya Milk and constipation

Soya Milk Linked to constipation

As some of you may know the consumption of cows milk is a major contributor to chronic constipation, and is also misdiagnosed in children with chronic constipation. So what’s the quick answer… switch to soya milk, but can soya milk also cause constipation?

When I first realized  I was lactose intolerant I switched to soya milk. I started incorporating it into my diet little by little but noticed the more I increased my intake the more constipated I was becoming.

While Soya milk usually adds monster to the stool and combats constipation too much can result in constipation. Luckily while studying to become nutritionist I came across some nutritional information explaining that Soya bean is high in protein and has a estrogen like hormone (a sexual hormone in women). I always know that at the end of my menstruation I get more constipated than normal due to drops in my hormone levels, believed that if I have increased estrogen levels I get constipation, the same result if I drink too much Soya milk.

Other foods That contain Soy:

  • Tofu/bean curd
  • Miso
  • Soy Sauce
  • Soy protein isolate
  • Tempeh
  • Sometimes used as an additive

The National Centre for Complementary an Alternative Medicine advises limiting your consumption of soya milk as I may result in unbalanced hormone levels. Other side effects of soya milk may include:

  • Vomiting
  • Diarrhoea
  • Nausea

The moral of the story is if you suffer with chronic constipation watch your intake of soya milk as it can result in constipation if drunk in excess.

Alternatives to Soy Milk:

Rice Milk

Almond Milk

Oat Milk

Coconut Milk

    Another issue in nearly all of these milks as commercially prepared (and some commercial cow milk) is the inclusion of carrageenan extract. I’m coming to the conclusion that the polysaccharides in carrageenan don’t help my IBS-D, though my main problem seems to be with fructans (in onions, many legumes and pulses, some fruit). I do ok with tofu but not soymilk, which often also has pea protein, soy protein isolate – I think these cause problems. Miso paste seems ok probably because it’s already well-fermented, and tempeh might also be ok for the same reason. But I’m not yet competely sure about the wakame & kombu seaweeds normally used in miso soup, for me.

    Making your own milk from almonds or rice in a blender is a good bet. Not sure about coconut milk yet for FODMAP-sensitive IBS, coconut meat too has fructo/galacto-oligosaccharides. Coconut oil is fine, it’s the water-soluble sugar chains that are a problem in all of these.

    Thanks for your blog. Good luck and never stop learning. :)

      I should say that if part of your problem with soymilk really is phytoestrogens, they’re still present in the fermented products (maybe a bit less). The worst for you in that case would probably be whole soybeans, for instance steamed as edamame. Isolated testing is tricky of course, and it can cost me a day or two of physical and psychological misery when I get something wrong, so I know you may not want to risk a test anytime soon. :)

      I sound similar to you but in a mirrored effect; most fructans cause my IBS-C to flare. I remember last year I tried Soy Protein Isolate and the chronic aftermath of pain was so bad, I had to go to hospital. I have to try and avoid most nuts, but some seeds are OK for me like pumpkin seeds, I guess because they’re high fibre.

      Thanks so much for commenting! :)
