The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

Soy consumption is related to hypogonadism and erectile dysfunction.

This post includes a synopsis of a paper published in Nutrition 2011 Feb 23 and a recipe for pepper crusted steak salad.

Study title and authors:
Hypogonadism and erectile dysfunction associated with soy product consumption.

Genetic Roulette: The Documented Health Risks of Genetically Engineered Foods
Siepmann presents the case of a 19-y-old type 1 diabetic but otherwise healthy man with sudden onset of loss of libido and erectile dysfunction after the ingestion of large quantities of soy-based products in a vegan-style diet. Blood levels of free and total testosterone and dehydroepiandrosterone (DHEA) were taken at the initial presentation for examination and continuously monitored up to 2 y after discontinuation of the vegan diet. Blood concentrations of free and total testosterone were initially decreased, whereas DHEA was increased. These parameters normalized within 1 y after cessation of the vegan diet. Normalization of testosterone and DHEA levels was paralleled by a constant improvement of symptoms; full sexual function was regained 1 y after cessation of the vegan diet. This case indicates that soy product consumption is related to hypogonadism and erectile dysfunction.

Recipe of the day

Pepper Crusted Steak Salad

◦1 lb. sirloin steak
Organic Grass Fed Top Sirloin Steak
Food Mall: Sirloin Steak
◦3 T fresh ground pepper
◦3 T olive oil
◦1 onion, sliced as thinly as possible
◦2 c shitake mushrooms, stems removed and sliced
◦1 T butter
◦2 heads romaine lettuce, chopped
◦3 green onions, sliced
◦3 oz. raw blue cheese


For the Steak:
Place the ground pepper on a plate and lay each side of the steak in the pepper. The harder you press the steak into the pepper, the more pepper will stick; therefore, the spicier the steak. Grill or saute the steak to your likeness. Once the steak has rested for at LEAST 5 minutes, slice it thinly against the grain for maximum tenderness.

For the Onions & Mushrooms:
Place 3T oil in a saute pan and turn the heat on medium-low. The secret to caramelized onions is patience–which I have very little of. Once the oil is warm, throw in the onions and toss around to get everyone coated. You don’t need to constantly stir the onions, but keep an eye on them and toss them around the pan every once in a while. You will eventually see the color start to change from white to yellow to gold. If the onions start to brown, you either have too little oil in the pan or the heat is too high–fix accordingly. The total process will take about 20 minutes. Be patient; or don’t be, and take the onions off the heat early–the result will still be sweet & tasty.

Once the onions are out, melt 2T butter in the pan and crank the heat to medium high. Toss in the mushrooms and let them saute for about 10 minutes. Make sure to scrape up all the onion bits that were left on the bottom of the pan.

Assembling the Salad:
While the onions are sauteing, chop, wash and dry the romaine lettuce. Place in a bowl, along with the green onions and some blue cheese crumbles, if you’re using it. Add the onions and mushrooms and top with the sliced steak.

For the Dressing:
2T whole grain dijon mustard
4T red wine vinegar
6T olive oil
S & P

Place all the ingredients in a container with a screw top lid or into a bowl and shake/whisk the heck out of it until it comes together. Pour on top of the salad.
