Getting cellulitis after consuming Natto!

Hi everyone,

I recently started incorporating natto (the Japanese fermented soybean) into my diet in hopes of increasing butyrate production, as my Biomesight stool test revealed that I was extremely low in it. The first week was amazing, and I even noticed improvements in my sleep, which has been a long-standing issue for me.

Encouraged by the results, I decided to double my portion of natto (I buy the frozen kind from a Japanese market). However, after a few days, I developed a red, painful rash on the skin on the side of my foot. I ended up visiting a doctor, who diagnosed me with cellulitis and prescribed antibiotics. Thankfully, the antibiotics worked quickly, and the swelling and rash improved.

What puzzles me is that cellulitis is typically caused by Streptococcus or Staphylococcus. Natto, on the other hand, contains Bacillus subtilis, which is known for its probiotic benefits and is supposed to have antimicrobial effects against these bacteria. So how could this have happened?

I’d really appreciate your thoughts, suggestions, and any insights on this. Thank you all for contributing to the discussion!

I think that freezing B. Subtilis might kill it, so I doubt you will have beneficial effect with Frozen Natto.

Is it possible that some people's colons and microbiomes are simply better at absorbing or utilizing butyrate? You might be producing a normal amount, but more efficient at using it, so less remains in the stool. Whatever butyrate comes out in the stool is wasted resources, so measuring that doesn't tell the whole story.

Well, I wouldn't assume the natto had anything to do with the cellulitis. It normally starts with a break in your skin. Now if you smeared the natto over your legs... :)
