See this site about
Reducing High Blood Pressure. It has a book (Fasting and Eating) at the bottom that is by an MD that cures people of high blood pressure, angina, intermittent claudication and other cardiovascular problems. It sites countless studies.
But vegans will not live longer than average unless they take a B-12 supplement and make sure to get omega-3 fatty acids. He treats very, very severe cases with fasting, switching to vegan diet and exercise program. With a vegan diet your husband can still be killed but with no other problems will very long without cardiovascular problems.
But your question has nothing to do with health. It is a question about money. It took doctors 40 years to accept the stethoscope so do not hold your breath. Instead of trying to spend less maybe you shoud try to earn more. The last that I heard the owner of this site makes about $30,000 monthly. That is $360,000 annually so he will not benefit from Obama's tax plan. He is in the same place as Joe the Plummer.
Also here is a healthy way that your husband can increase his cholesterol (for a month or more) without eating animal foods. He can fast a couple of weeks. This is explained in that book mentioned above. This causes the cholesterol to go very high due to the increase in good cholesterol. A guy with cholesterol of 150 can fast till it goes up to 300.
Can you guess why? The fasting causes the arteries to be cleaned so fast that an old person can get the arteries of a young person. Again though your question is about money, not health.
