As always, show notes are below.

July 19, 2011 | Tonight on Summer Tomato Live we’re discussing soy. Some say it prevents cancer, others think it promotes it, and some claim it’s evil for causing man boobs. We’ll get to the bottom of these issues and more today during the show.

Join us at 6:00pm PST to learn about how soy affects your health and what to do about it.

Soy sauce

Someone asked during the show how this advice applies to soy sauce. Turns out there are 2 different methods of brewing soy sauce. The traditional way is fermented and has the same attributes as fermented soy products mentioned in the episode. The other method creates the sauces by hydrolyzing soy, which creates a number of unwanted byproducts including MSG and potentially some carcinogenic chemicals. The Wikipedia article on soy sauce is very informative.

What about demasculizing men?

One of the biggest fears men have about eating soy is the possibility of phytoestrogens demasculizing men, creating sexual dysfunction, infertility and the dreaded man boobs.

Indeed, there have been several studies in rodents suggesting that soy can interfere with reproductive pathways and fertility. However, human and monkey studies show that most men have no need to fear soy.

Show notes:

There is a huge amount of politics surrounding this science, because of the powerful influence of dairy industries around the world. This makes data difficult to interpret. The following review and its rebuttal regarding the role of milk in type 1 diabetes is a perfect example of what I mean:

Dairy & type 1 diabetes

Dairy and osteoporosis

Dairy and acne

Dairy/calcium and heart disease

Dairy/calcium and prostate cancer

Dairy/calcium and colon cancer

Dairy & breast cancer

Dairy & weight loss (very tough to find studies not funded by dairy industry)

  • Moderate weight loss from dairy (but rarely from intervention studies w/o caloric restriction)
  • Possible mechanisms include:
    • Ca++
    • protein
    • conjugated lineoleic acid (CLA)
    • medium-chain fatty acids
  • My interpretation: dairy not likely to have big impact on body weight

Cheese protects against cancer and heart disease?

Extras

  • Processed ice cream contains beaver anal gland?
  • Wikipedia
