Why processed foods are so bad, artisan vs grocery store bread, and finding time to cook healthy food – Episode 11 – Summer Tomato Live

by | Aug 17, 2011

This is one of my favorite discussions on health and processed food so far, thanks everyone for your questions. As always, show notes are below.

August 17, 2011 | Episode 11 of Summer Tomato Live will be here tonight at 6pm PST. The format is a little different this week. Instead of covering one topic, I’ll be answering 3 recent subscribers questions. The questions I’ll be answering are:

  1. What’s the deal with processed foods, why are they so bad?
  2. Are artisan breads as bad as grocery store breads?
  3. Cooking healthy food takes me forever. How can I make it quicker and less overwhelming?

Summer Tomato Live normally requires a subscriber password, but since we have so many new readers this week (thank you TIME Magazine!) I’m going to leave this episode open so anyone can participate.

Also to celebrate making TIME’s list of best websites, for the rest of the week I’m offering one free month off a new Tomato Slice subscription. So if you’ve been thinking about signing up, now would be a great time.

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.
