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.

Dietary phytates and tannins may lead to iron deficiency

This post includes a synopsis of a paper published in the American Journal of Public Health 1998 Apr;88(4):576-80 and a recipe for grilled steaks.

Study title and authors:
Deficient dietary iron intakes among women and children in Russia: evidence from the Russian Longitudinal Monitoring Survey.

This paper can be accessed at:

The study of 10,548 women and children evaluated the iron sufficiency of the Russian diet.

The study found:
(a)  Dietary iron intakes were deficient in the most vulnerable groups: young children and women of reproductive age.
(b) Poverty status was strongly associated with deficiency.
(c) Grain products rich in phytates, (which inhibit iron absorption), were the major food source of iron in Russia.
(d) High intakes of tea rich in tannins, also inhibited iron bioavailability.

To conclude: The dietary data suggests that Russian women and children are at high risk of iron deficiency. Since changes in eating behavior could potentially double iron bioavailability, (consuming less grain and less tea), educational programs should be explored as a strategy for improving iron nutriture.

Rib-Eye Steak

As many steaks as you will need to feed your family, bring to room temperature, sprinkle each side with sea salt and freshly cracked black pepper and grill over medium high heat. We like our steak rare to medium rare so for thinner cuts of meat it only takes about 5 min. per side on the grill. Let your meat rest for at least 10-15 minutes before you slice into it so that you do not lose all those precious juices.
