The Optimal Macronutrient Intake Trial for Heart Health
(OmniHeart) study compared the effects of three heart-healthy
diets, all based on the Dietary Approaches to Stop Hypertension
(DASH) diet — one emphasized carbohydrates,
another emphasized protein, and the third emphasized unsaturated
fat. Although all three lowered blood pressure and improved
cholesterol and triglyceride levels, the higher-protein and
higher-unsaturated-fat diets worked best. The general plan for
all three diets looked like this:

A healthy diet that includes poultry, fish, whole grains,
vegetables and fruits, nuts, legumes, low-fat dairy products, and
unsaturated fats can help control high blood pressure.
The layer of endothelial cells that lines blood vessels helps
protect them and keep them functioning properly, but smoking,
poor diet, and other risk factors can damage the endothelium,
opening the door to heart disease.
If replacing a heart valve becomes necessary, the decision is
mainly a choice between a mechanical valve or a tissue valve. A
mechanical valve requires the recipient to take warfarin to
prevent clotting and a tissue valve will not last as long as a
mechanical one. When it comes to choosing a new heart valve, your
doctor's advice is definitely important. But your personal
preferences and situation should also be part of the decision.

I am an 80-year-old man. Forty years ago I had a heart attack
after completing a long hike. I stopped smoking but remained very
active, doing a lot of hiking and kayaking. I now walk 2 to 3
miles a day, work out with weights three times a week, and walk
up and down 25 flights of stairs twice a week. My blood pressure,
with the help of medications, hovers around 125/70; my resting
pulse is 55. A year ago I tore my quadriceps tendon, but am now
back to my usual activities. My physician thinks I am pushing too
hard and has urged me to take it easier. Is he right? Should I
follow his recommendation?
My family has squabbled about oats for some time. Some members
say that to get the biggest health benefit from oats you need to
eat them raw, at room temperature, and moistened with water.
Others say they should be cooked. Does cooking take something
beneficial out of oats? Can you bring us some peace at breakfast
