...there is now strong evidence that smoking promotes erectile dysfunction? Italian researchers followed 860 male subjects between the ages of 18 and 44 for three years. The subjects were divided into three groups: smokers, never smokers and former smokers. Those that smoked were 30% to 90% more likely to have problems getting it up. Nicotine is a vasoconstrictor, which means it causes the diameter of arteries to become smaller. Not only is this bad for Mr. Happy because it reduces blood flow, it is systemically bad for the body because it raises blood pressure. Another negative effect smoking has is chemicals that are inhaled decrease the amount of nitric oxide released by blood vessels. Nitric oxide is responsible for the relaxation of blood vessels (arteries) which allows your johnson to come to attention when aroused. Those of you who smoke because you think it makes you look cool (virtually everyone who starts) had better start thinking about how cool you’ll look with a frustrated naked woman in front of you.

…fish oil may be better at treating attention deficit hyperactivity disorder (ADHD) than Ritalin? A study at the University of Adelaide in Australia found that just six capsules of fish oil per day vastly improved children’s behavior without the drug related side-effects. In just 15 weeks, 30% to 40% of the children taking fish oil showed improvement. After 30 weeks, up to 50% of the children were showing improvement. Because of technology and big business, omega 3 fatty acids are found only in small amounts in the meats we buy. Even the farmed salmon you buy at the grocery store has very low amounts of omega 3 fatty acids. In order to get these valuable fatty acids from foods, you need to buy meat from farms that graze their animals and fish that is wild caught. (

…cortisol blocking products are ineffective at cutting fat? We’ve all seen the commercials. Several supplements claim to aid in weight loss by lowering cortisol levels. Malcom Low, MD, PhD, senior scientist at the Center for the Study of weight Regulation and Associated Disorders at Oregon Health & Science University in Portland, says even if the supplements did lower cortisol, it would have little effect on weight loss. Weight loss is a very complex issue and there is no single answer. Remember, if it sounds too good to be true, it almost always is. (

…that saturated fats are not the devil they’ve been portrayed as in the media? We’ve had it rammed down our throats that we need to decrease our consumption of unhealthy saturated fat and increase our consumption of polyunsaturated fats for more than half a century. And we Americans have done just what we’ve been told to do. We’ve dropped our animal fat consumption by more than 21% since 1910 and our vegetable oil consumption has increased 423%. If animal fats (saturated) are so dangerous and vegetable oils (polyunsaturated) are so healthy, why are we so unhealthy as a nation? (

…there are two types of lies: There are lies, and there are statistics. According to a New York Times article on May 9, pharmaceutical companies pay physicians to conduct negative studies on the competition and publish the results. It also discusses the fact that drug companies also pay physicians to promote new medicines through professional articles and at medical conferences. These types of marketing tactics are pervasive in the industry and have been documented by two former editors of The New England Journal of Medicine. The article notes that the best way to discourage this practice is to mandate full disclosure of links between drug companies and physicians. (
