I have perused the internet recently regarding vegetables(whether to include them or not, if so which are best--least fructose, least starchy carbs, most nutrients, least toxic, most plentiful where I live for the least cost). I have sifted through PALEO HACKS again and again attempting to find out info. about vegetables regarding these topics and much of it has been fruiful. A concern of mine which has arisen in these investigations is about BRASSICAS: The internet sources I've investigated state that they increase testosterone levels("cruciferous vegetable" and those of the "brassica" family). This I would look upon as desirable. I have also found contradictory messages which has been discouraging(...me from eating them). PALEO HACKS and other sources caution that brassicas are goitrogenic and reduce thyroid hormone. Who can be believed? My questions are as follows if anyone cares to give some insight into the issue: (1) Do they increase/decrease testosterone (2) "........................"thyroid hormone (3) What is the relationship between these hormones and do they not have a complementary effect/mechanism of action(which I had previously thought) (4) For general health purposes, what would be the best strategy: to include or exclude this family of vegetables(especially cabbage, turnips, rutabagas) given that one wants high testosterone and thyroid hormone? (5)Also, I have heard that these vegetables(especially cabbage) are high fructose True?Please help me in my endeavors of increasing/decreasing/balancing...ie. controlling the self.
I can't answer about brassicas increasing testosterone, but they certainly can suppress the thyroid. If you don't currently have a thyroid problem, then I wouldn't worry about it, if you do have a thyroid problem, then I would minimize how much of them you eat. Cooking reduces the goitrogens.
Personally, hypothyroidism runs in my family- almost all the women on my mom's side of the family are hypo, and I have pretty much all of the symptoms, though the tests come out normal. Just to be on the safe side, I try to keep cruciferous vegetables to one serving a day, usually cooked.
Travis is correct. And SHBG goes up in men due to phytoestrogens and increased levels of estradiol. We see this in eaters of soy products, obese men, and Men who aromatize testosterone......like body builders using a ton of exogenous testosterone or tons of DHEA or pregnenolone when they should not.
The Blood Type diet (blood type O) does indeed state that most brassica's (cabbage,brussel sprouts,cauliflower) aren't beneficial to type O,except broccolli, and that they will inhibit weight loss.... Not sure what to think of that....
