The author found that soy formulas provide infants with a daily dose rate of 3 mg/kg body weight total isoflavones, "which is maintained at a fairly constant level between 0-4 months of age. . . . This rate of isoflavone intake is much greater than that shown in adult humans to alter reproductive hormones."

Recipe of the day

Lamb Shanks with Wilted Spinach

Ingredient list:

2 lamb shanks

2 bags of fresh spinach

Food Mall: Lamb Shanks

Extra virgin olive oil

Black pepper
Garlic powder
Salt

Directions:
Add 1 or 2 tablespoons of olive oil to pressure cooker over medium heat. Season both sides of lamb shank with salt, garlic powder, and black pepper to taste. Add lamb shanks to hot oil and sear four minutes on the first side and then four minutes on the other side to brown the meat. Add one cup of water. Lock top on pressure cooker. Increase heat to high. After achieving high pressure, reduce heat to the lowest level consistent with maintaining high pressure. Cook under high pressure for 20 minutes. Turn off heat, allow pressure to come down naturally, and remove top.

Meanwhile, add several tablespoons of olive oil to a sauté pan over medium heat. Add fresh spinach to pan. Add salt, garlic powder, and black pepper to taste. Stir with a spatula. As the spinach wilts down, add more fresh spinach, salt, garlic powder, black pepper, and, as needed, olive oil, until you have enough wilted spinach to serve two. Transfer spinach to plates. Add a lamb shank to each plate. Enjoy!
