polyunsaturated fats linked to higher cancer risk
|

for years we've been told to avoid butter and instead use vegetable oils as our primary fat source. mainstream science claims this will save our hearts. but industrial oils like soybean, corn and canola oil are hiding a dirty little secret: consuming them could very well increase your risk of cancer. what are polyunsaturated fats? unlike saturated fats and monounsaturated fats, polyunsaturated fats (also known as pufas for short) are linked by multiple double bonds. this is what makes polyunsaturated oils highly unstable and vulnerable to oxidation. the cancer connection many experts now acknowledge that refined polyunsaturated oils are damaged fats and should be avoided. this leads to the assumption that cold-pressed organic oils are acceptable because they are less refined. however, even gently processed oils are unstable and oxidation can still occur once these fats are in the body. oxidation is linked to cancer and other degenerative diseases. in addition to the dangers of oxidation, there are also bonafide concerns about the omega-6 content of polyunsaturated oils. a recent san francisco study demonstrated that under laboratory conditions, omega-6 fatty acids could accelerate the growth of prostate tumor cells. other studies show that improving the omega-3 to omega-6 ratio can lower the risk of certain cancers. experts vary in their specific ratio recommendations, but most suggest a ratio of between 1:1 and 1:4 at most. the average modern diet has an omega-3 to omega-6 ratio of 1:20 or more! the blame for this can be squarely placed on the rapid increase of vegetable oils in our diets during the past century. while some vegetable oils do contain small amounts of omega-3 fatty acids, for the most part they consist of omega-6. while some recommend increasing omega-3 consumption to combat this effect, this problem is far more effectively resolved by reducing omega-6 intake. eliminating or drastically decreasing polyunsaturated oil consumption is the best way to do this. how to decrease your polyunsaturated fat intake here's how you can cut excess pufas from your diet: 1. avoid commercial fried foods. with very few exceptions, these are cooked in polyunsaturated oils and contain highly damaged fats. 2. avoid commercial salad dressings, mayonnaise and other fatty condiments. unless otherwise noted, these are generally made with refined vegetable oils. 3. avoid commercial baked goods. these usually contain a lot of refined flour and sugar, so they should be avoided anyway. but their high pufa content gives you another good reason to leave these items alone. 4. cook and bake with butter, coconut oil, olive oil and other heat stable oils. frankly, these taste a whole lot better than veggie oils anyway, so making this trade should be easy. 5. go easy on the nuts. while these may be hailed as a health food by many experts, in excess nuts can easily skew your omega-3 to omega-6 ratio and push your polyunsaturated fat intake over the limit. hazelnuts and macadamia nuts are the most forgiving since these contain the lowest pufa content. a historical perspective there are no traditional cultures who liberally used polyunsaturated oils in their diets. keep in mind that these cultures often exhibited excellent health and did not suffer from modern diseases such as diabetes, cancer and heart disease. we should take a hint from our ancestors and ditch the polyunsaturated oils. for more information: http://www.natural-cancer-cures.com... http://www.healingnaturallybybee.co... http://www.sciencedaily.com/release...

study after study over the past decade has come up with the same conclusion: omega-3 fatty acids from fish or fish oil supplements decrease the risk of atherosclerosis, potentially deadly arrhythmias, heart attacks and sudden cardiac death. omega-3 fats have also been found to reduce heart failure death by about nine percent in patients with grave prognoses. but what about people with serious heart disease who have already had heart attacks.

many diets promoted by companies and individuals rely on calorie restriction or the complete elimination of certain food groups in the quest to lose weight. additionally, the unhealthy reliance on appetite suppressants and artificial sweeteners is promoted. diets do not generally work in the long term and can even be dangerous. proteins, fats and carbohydrates should be correctly chosen for optimum health and ideal weight.

you're probably already aware of the benefits of omega-3 fatty acids on cardiovascular health, but did you know that omega-3s are also extremely beneficial for moods and cognitive function? in fact, there's a tremendous amount of good evidence demonstrating that omega-3 fatty acids can help enhance brain function and prevent depression.below, we present a collection of supporting quotes and testimonials from authors and researchers in the natural health field.

from heart-friendly margarines to sugary cereals that strengthen bones, once-demonized foods are being spiked with nutrients to give them a healthier glow — and consumers are biting, even on some that are little more than dressed-up junk food.a report released thursday finds that even in a weak economy, people will pay a premium for products seen as preventing a health problem or providing a good alternative to sodas and empty-calorie snacks.

fish oil contains two naturally occurring fatty acids, epa and dha. these fatty acids stimulate the body's anti-inflammatory processes and help relieve joint pain, much the same as nsaids and cox-2 inhibitors, but without the side effects. an excess of proinflammatory messenger molecules causes joint pain, and consumption of fish oil prevents this build up.both epa and dha are necessary for many functions in the body, but are not manufactured in the body in quantities sufficient for their use.

an omega-3 fatty acid found in fish oil has been shown to improve insulin function in overweight individuals who are vulnerable to type 2 diabetes, according to a report from reuters health. researchers found that daily supplements of docosahexaenoic acid (dha) taken over a period of three months produced a \"clinically significant\" improvement in insulin sensitivity in overweight subjects of the study.

eating fish a few times a week significantly cuts the risk of death from a heart attack or other heart problems, according to two new studies published this week, adding to a growing body of evidence that oils in fish are good for you. both studies are based on long-term monitoring of the health of medical professionals and the findings are important because half the people who suddenly collapse and die of a heart attack do not have a history of heart problems.
