Is there something fishy going on with omega-3 fatty acids? For years, major health and medical organizations have recommended fish oil supplements rich in omega-3s to reduce the threat of heart disease. In Europe, where support is particularly enthusiastic, a doctor's failure to recommend the supplements is viewed by some as bordering on malpractice. But several recent studies have raised questions about the benefits of fish oil, sparking no small amount of confusion. A report published Wednesday in the Journal of the American Medical Assn.

With each year, the nutritional story of fat seems to become more complicated. It used to be fairly simple: Saturated fats were the bad guys, polyunsaturated fats were the good guys. Then came the trans fat revelation. Here's another head-scratching twist: an ideal ratio of fats. Many nutritionists are concerned that our consumption of two kinds of polyunsaturated fatty acids -- the omega-3 and omega-6 fats -- is way out of balance these days and that our health may be paying the price.

Re "The Fat From These Pigs May End Up Helping Your Heart," March 27 As a gastroenterologist, I have good reason for doubting the benefits of the new omega-3 enhanced pigs. According to a new British Medical Journal study, there is no evidence that taking omega-3 supplements or eating oily fish rich in omega-3 fatty acids has any health benefit. Moreover, pork is high in cholesterol and saturated fat, two key contributors to heart disease. It simply doesn't make sense for people to consume such unhealthy products when a healthy, plant-based diet rich in fruits, vegetables and whole grains is proven to lower cholesterol.

Fish oil has long been touted as one of nature's heart-helping natural compounds, but is it worth popping that jellied pill as part of your nutrition regime? Might depend on who you are. A Dutch study found that people who had already suffered heart attacks did not significantly reduce their risk of heart attack, stroke, heart failure and other cardiovascular events by eating about 400 mg of fish fatty acids per day. But the supplement did help those patients who had diabetes in addition to a past heart attack.

Q: Which is better, fish oil or flax oil capsules? Both contain omega-3 fatty acids, but it is much harder for the body to utilize the fats from flaxseed oil. If your goal is to lower cholesterol and triglycerides, fish oil is preferable. During a recent stay in the hospital, while swallowing pills I mentioned to the nurse that I had a dread of having a large pill get stuck in my throat. She explained that the right way to swallow is to lower your chin down toward your chest.

Swedish women who ate fatty fish such as salmon, mackerel and herring at least once a week had a significantly lower risk of kidney cancer compared with consumers of lean fish, a new study has found. The 15-year study found those who regularly ate fish containing lots of fish oil that is rich in omega-3 acids and vitamin D had a 74% lower risk of getting kidney cancer compared with those who ate no fish at all.

Omega-3 fatty acids can be found in high concentrations in the retina of the eye, leading to speculation that adequate levels of the substance may be important in preventing some diseases of the eye. Animal studies also suggest that omega-3s, found mostly in seafood, protect against eye diseases. A new study adds more evidence, finding that people who consume a lot of fish and shellfish have lower rates of age-related macular degeneration. The condition is the most common cause of blindness in the United States.

Lately I've tried to make sense of the dizzying news from the world of nutritional science. Believe me, it hasn't been easy. Let's steep right in with the news about dark tea, which scientists suggest we drink in great quantities every day to promote bone density. But wait, I'm already drinking eight glasses of water daily; adding to this liquid load just won't work. There are only so many potty breaks one can take in a day before the boss notices, sidles over to you and asks if you need to see a urologist.

Fish oil fed to rhesus monkeys blocks hardening of the arteries induced by high-fat foods, researchers reported at a American Heart Assn. meeting. In a finding that may have major implications for the human diet, University of Chicago scientists said their study is the first to demonstrate that fish oil directly reduces cholesterol buildup in primates, adding to a growing body of evidence that suggests a diet rich in fish can help prevent heart disease.
