Nuts are a good fat source.  Your body needs some fat for proper development and function.  Try a nutrition search or USDA web site for proper percentage mix.  Tho fat intake in the USA is easy to find and is usually a problem of too much. Fast food and processed foods are lousy sources of the wrong types of fat.

in what we eat and if we do exercise. Remember not all cholesterol is bad. THere are LDLs and HDLs. To have good cholesterol it is good to eat a small hand full of nuts. to stay away from bad cholesterol stay away from fatty food. SOy milk can also bring down your cholesterol.

Fish Oil \n\n\nClaims, Benefits: Prevents heart disease, alleviates auto-immune disorders, plus many other claims. \n\nBottom Line: Fish oil contains heart-healthy omega-3 fatty acids. Many studies find some beneficial effect, especially against heart attacks. But supplements can have adverse effects. We recommend fish, but not fish oil capsules, except for those with heart disease or auto-immune disorders. \n\nFull article, Wellness Letter, November 2003: \n\nShould You Take Fish Oil Pills? \n\nNearly every month there’s another study showing the health benefits of fish, and some of these studies have used fish-oil supplements. The Wellness Letter has never been big on these supplements. They contain the heart-healthy omega-3 fatty acids, but not the other good things in fish, and they are not without risk. Our opinion about these supplements has changed somewhat, however, because of ongoing research and new advice from the American Heart Association (AHA). \n\nHere’s who should consider taking fish-oil supplements: \n\nPeople who already have coronary artery disease, notably those who have had a heart attack. There is solid evidence that omega-3s can help protect them. Thus, last year the AHA started recommending 1 gram a day of omega-3s, preferably from fish, for these people, with their doctors’ approval. That’s the amount in a serving of fatty fish, such as 3 ounces of salmon. But most people don’t eat fish every day, and many choose less-fatty fish (it takes 12 ounces of canned tuna or 7 ounces of flounder to supply 1 gram of omega-3s). Moreover, since fish may contain mercury, we advise limiting fish intake to 12 ounces a week, on average. So to get enough omega-3s without going overboard on fish, people with heart disease should consider taking fish-oil supplements on days when they don’t eat fish. \n\nThose with high triglycerides. These fats in the blood increase the risk of heart disease. It’s well known that omega-3s help lower triglycerides. The AHA recommends 2 to 4 grams a day from supplements for people with high triglycerides, but only under the care of a physician. \n\nThose with rheumatoid arthritis, psoriasis, or other auto-immune disorders. Omega-3s may help relieve the inflammatory symptoms of such auto-immune diseases by suppressing the immune response. Thus, they can help reduce the joint pain and swelling of rheumatoid arthritis. The Arthritis Foundation says the supplements are worth trying. Clinical studies suggest about 3 grams of omega-3s a day. \n\nWhat about people with coronary risk factors, such as diabetes or high blood pressure, but no apparent heart disease? We suggest that they get their omega-3s from two or three weekly servings of fatty fish. There have been no clinical studies to see if fish-oil supplements will help them. \n\nNot for everyone \n\nIf fish oil is so great, why shouldn’t everyone take supplements? \n\n• The decreased ability of the blood to clot, which helps prevent heart attacks, has a negative side, notably an increased risk of hemorrhagic stroke. People with bleeding disorders, those taking anticoagulants, and those with uncontrolled hypertension should not take fish oil supplements.\n\n• Large doses of fish oil may suppress the immune system. Thus, supplements may be risky for those with weakened immune systems. What’s a "large dose"? One definition is 3 grams or more a day, but no one really knows what the cutoff point is.\n\n• Large doses can increase glucose levels in people with diabetes.\n\n• Large doses can cause nausea, diarrhea, belching, and a bad taste in the mouth. \n\n• The supplements may contain contaminants and may not contain the labeled dose. A recent test by Consumer Reports of top-selling supplements was reassuring on both counts, even for the least expensive brands, but that doesn’t mean that the next batches will be okay—or that other brands on the market are. Last year a test by ConsumerLab.com found no de

Unfortunately both butter and margarine have their down sides..\n\nButter contains a lot of saturated fat which raises the bad cholesterol in your bloodstream.\n\nMargarine contains polyunsaturated fats, which are considered healthy fats. However.. when margarine is created it undergoes a hydrogenation process of fats. This turns some of the polyunsaturated fats in to saturated fats.\nAlso some of the polyunsaturated fat molecules are converted in to transfatty acids which also raise bad cholesterol in the bloodstream.\n\nAs an alternative you may consider using avocado as a spread. It contains lots of natural unsaturated fat which raises good scholesterol in the blood.\n\nOr you could drizzle some polyunsaturated oil over the bread like sunflower oil or fish oil.\n\nUnfortunately I don't like the alternatives and I just go with what I think is the lesser of the two evils.. margarine.\n\nHope I helped somehow.

Yes, fish contains Omega-3 which is very good for you. I have always heard Salmon is the best though. I think it is higher in Omega-3.

Omega-3 fatty acids are only naturally found in flax seed oil and fish oil from fish with red coloured flesh. Like salmon for instance. Omega-3 fatty acids are required by the brain to function at peak efficiency. They also reduce bad cholesterol levels. There are also Omega-6 fatty acids also commonly found in beef, pork, chicken and fried foods. O6 acids are not good for the body in large quantities and lead to heart attacks and blood clots.\n\n I take a gram of O3 acid at dinner every day. I find it helps to order thoughts and seems to be a mood stablizer, for me at least. If you go for a fish based source be warned that not all fish oils contain significant amounts of Omega-3 acids. I use the Organika brand of wild harvested Pacific salmon oil. It contains a garenteed amount of the O-3 acids EPA and DHA in eack softgel tab. Stay away from the " Natural Factors " brand of fish oil as from my experience it does not contain any EPA and DHA and did nothing for me. As a warning do not take more than a gram or 2 of O-3 oil per day. Too much oil thins the blood and puts an additional strain on the heart as it works harder to pump the thinner blood. Not good if you have a heart condition of any sort.\n\nAs for why O-3 acids are named the way they are that would have been up to their discoverer. Try searching the web for that person and you may find the answer to the 2nd part of your question.

The American Heart Association recommends the consumption of 1g of fish oil daily, preferably by eating fish, for patients with coronary heart disease.[1]\n\nAccording to a study from Louisiana State University in September 2005, fish oil may help protect the brain from cognitive problems associated with Alzheimer's disease\n\n\nThe liver of fish and many animals, such as seals and whales, contains, besides Omega-3, the active form of Vitamin A, such as in cod liver oil

I prefer a total EFA oil (Flax, Borage, Evening Primrose). I believe they are far better because your average fish oil(especially those obtained from fish liver) can be tainted with mercury, PCB's, organo-chloride pesticides, and dioxins. Most of them are removed by processing, but the fish oil molecules are ultimately damaged and become toxic, which in turn totally undermines your reasons for taking it in the first place. Total EFA oil has all the same benefits of fish oil, without the toxins.\n\nIt's best to get a total EFA oil blend that is certified organic. I use Udos oil which you can find in natural food stores.

Flax is rich in Omega 3 EFAs which almost everyone has a great deficiency in. \nHemp also contain Omega 6 EFAs as well as Omega 3s. So if you really just need Omega 3s Flax is the best choice.\nIf you also want Omega 6s then Hemp. \n\nBTW: Flax is probably the cheapest. You can buy a small bag that could last you a couple of months for less than $3 at any health food store.  All you have to do is grind it up in a coffee grinder and sprinkle the crushed seeds onto cereal, salads or bake into bread or muffins. \n\nI tried hemp oil some time back and didn't care for how it made me feel in the morning.  \nYou might try both in small amounts one at a time and take note of how you feel afterwards.\n\nThe very best is fish oil but you have to make sure it's filtered. The body must convert vegetable sources of Omega 3s to the kind your body can use.

Calories are good for you, they are a measurement of energy, which you need. However, there is a reading right next to CALORIES which says CALORIES FROM FAT, and most of the time if the fat is more than 50% of the main caloric intake it is bad. There's a difference between "good" fats and "bad" fats, so you have to know your food groups pretty well. Unsalted peanuts, sunflower seeds, oils, and meats are usually fully saturated with fat from their calories, but these are whole fats which the body takes longer to break down, which means they will burn more calories than something like a donut. These fats are essential, so don't stay away from whole foods that are high in fat. Mainly, look at the sugar content (added sugar) and the grams of carbohydrates.

* Pork fat is the most saturated type of fat in the animal kingdom and can increase the risk of high cholesterol and cardiovascular disease. \n* Its salty meat is an additional risk for the kidneys, heart and for hypertensive patients. \n* Pigs will eat anything and everything, including their own excreta. This makes their bodies an ideal host for several microorganisms that are known to be hazardous to human health if consumed regularly. \n\nHowever: Scientists are breeding pigs to have the healthy fatty acids found in fish which will be good for the heart, but without the risk of heavy metal accumulation you see in real fish.

Omega-3 fatty acids are important building blocks of our cell membranes, signaling pathways and neurological systems. They play a critical role in many functions in the body and are essential for good health. The benefits of omega-3 fatty acids in cardiovascular disease are so well demonstrated that the American Heart Association recommends increased fish intake and/or omega-3 supplements. Scientists and physicians have also discovered many other benefits of omega-3 fatty acids.

that's a lot to answer so i'm not putting all the long details here. go to this link: http://www.answers.com/lipids .\n\nthat site is actually really helpful when you need to find out anything.

I am not a doctor, but I am a special education teacher of children with autism, and try to keep up with current autism research. I have not heard anything about Omega 3 and Omega 6 being used for autism, but I think that these are part of a healthy diet. I think that a healthy, balanced diet is important for all kids, and can help improve behavior and academics for all children. \n\nI would also exersise caution in dealing with anything that is labeled as a "cure" or "treatment" until you have done serious research into it. There are many "fad treatments" out there, and many are not shown to be effective. Please be especially carefully with any kind of "Mercury detox" or anything similar. There have been news reports of these causing death in some children. There is not enough research to know how harmful these are.
