Omega 3's

I often recommend to my clients to take Omega 3 Fatty Acids. I thinik there are many brands out there but this one has the correct ratio and a decent price. I recommend you take 1-2 pills a day. I personally take about 3-6 but I really think with all the exercise I do (and you now) that our bodies require more.
It's magical! Ok... that's obviously an exaggeration, but from all of the scientific studies done and all of the medical research known, an omega 3 fish oil supplement is my pick for the closest thing to a real life miracle pill.
Let's take a look at some of its benefits taken directly from MedlinePlus, which is a service of the US National Library of Medicine: - lowers blood triglyceride levels
- reduces the risk of heart attack
- reduces the risk of dangerous abnormal heart rhythms
- reduces the risk of strokes
- slows the buildup of atherosclerotic plaques
- lowers blood pressure
- reduces stiffness and joint tenderness associated with Rheumatoid arthritis An omega 3 fish oil supplement may also help improve or prevent the following: - Alzheimer's disease and dementia
- depression
- heart disease
- cancer
- arthritis
- diabetes
- hyperactivity
- ADHD It has also been shown to improve a person's ability to concentrate and just think clearer in general. And, as if all of this isn't enough, fish oil is also highly recommended by nearly every well respected strength and conditioning coach, trainer, and diet/fitness/nutrition expert of any kind as one of the few supplements that should be taken by anyone with the goal of building muscle, losing fat, or improving their fitness level or athletic ability in any capacity. Everything mentioned above has at least some amount actual scientific proof behind it. Researching some other sources showed me that some people experienced other benefits not mentioned above. For example, I've heard of people claiming to have improved vision, improved memory, improved mood, and less back pain. Long story short, a fish oil supplement appears to improve our body's ability to do damn near everything. For me personally, I feel I experienced some of the mental and physical benefits. I noticed a definite improvement in mental clarity and really just the way I feel in general. Now, I didn't develop any kind of super powers or anything, but after a couple of weeks, I felt like I noticed a difference. I remember reading the phrase "an enhanced well being" when doing my fish oil research. That's a really good way of describing it. And physically, I feel I noticed an improved calorie partitioning effect, meaning when consuming an excess of calories, more calories went towards the building of new muscle rather than the storing of new fat. I also felt a similar effect when in a caloric deficit, meaning my body did a better job of using stored body fat for energy rather than muscle. Basically, I felt I did indeed experience an overall improvement both physically and mentally.
But really, even if I felt exactly 100% the same, I'd still be taking an omega 3 fish oil supplement anyway. Why? Because even if I didn't notice any of its benefits, the fact that there is actual scientific proof that it may help improve or prevent even 1 (let alone all) of the diseases and disorders listed above is MORE than enough convincing for me.

Trans Fats and Partially Hydrogenated Oils

A few weeks ago I received an email from a mommy friend of mine who is concerned with how her 4 year old eats and wanted advise. She seemed to be confused about what is the difference between trans fats and saturated fats. Here is my response:

Q.What is Trans Fat?
A. Most trans fat is a monounsaturated tone (one double bond) fatty acid. The shape of trans-fat molecules is more like cholesterol-raising saturated fat than a typical monounsaturated fatty acid. Perhaps for that reason, it increases cholesterol levels in blood and increases the risk of heart disease.

Q. Where does trans fat come from?
A. According to the Food and Drug Administration (FDA), in 1994-96 we consumed about 5.6grams of trans fat per day. Most of that trans fat comes from the 40,000-plus foods that contain partially hydrogenated vegetable oil. Those include many stick margarines, biscuits, pastries, cookies, crackers, icings, and deep-fried foods at restaurants. Because Frito-Lay, margarine producers, and some other companies recently stopped using (or cut back on the use of)partially hydrogenated oils, we now are consuming a little less trans fat. About one-fifth (1.2g) of the trans fat came from natural sources, especially beef and milk prodicts(bacteria in cattle produce trans fat that gets into meat and milk). A little more occurs naturally in vegetable oils and forms when vegetable oils are purified.

Q. How is partially hydrogenated oil made?
A. To convert soybean, cottonseed, or other liquid oil into a solid shortening, the oil is heated in the presence of hydrogen and a catalyst. That hydrogenation process converts some polyunsaturated fatty acids to monounsaturated and saturated fatty acids. It also converts some monounsaturated fatty acids to saturated fatty acids. Thus, a healthful oil is converted into a harmful one. The problem arises when some of the fatty aieds are converted to the "trans" form. The term "trans" comes from the fact that two parts of fatty acid molecules are on opposite sides of double bonds. In the usual "cis" fatty acids, the two parts are on the same side of the double bonds. The degree of hydrogenation determines how solid the final product will be and how much of the different fatty acids it will contain.

Q. Where oils partially hydrogenated?
A. To increase shelf life and obtain the cooking properties of solid shortenings, oils are partially hydrogenated. That eliminates most of the unstable fatty acids--those with three or two double bonds. Partially hydrogenated oils have been used to replace butter, lard, palm oil, coconut oil, and other "hard" fats in such foods as many processed foods. Fortunately, food technologists have been figuring out increasing better ways to make those foods taste better without hard fats.

Q. Are fully hydrogenated oils even worse that partially hydrogenated oils?
A. No. Surprisingly, fully hydrogenated oils appear to be innocuous. In the case of fully hydrogenated soybean oil, the hydrogenation process increases the amount of saturated fat, but most of that fat is stearic acid. Stearic acid does not raise "bad" (LDL) cholesterol levels, because the body converts it quickly to monounsaturated oleic acid ( the acharacteristic fatty acid in olive oil).

Q.Why are partially hydrogenated oil and trans fat so bad for your health?
A. Trans fat increases the amount of "bad" (LDL) cholesterol in blood, and the increases the risk of heart disease. It also decreases the "good" ( HDL) cholesterol, which may increase the risk of heart disease even more. Preliminary research suggests that trans fat might have additional harmful effects on the body. Finally, the hydrogenation process destroys some of the vitamin K in vegetable oil, which might be a problem for consumers who have marginal intakes of that vitamin.

Q. How bad is trans fat?
A. Extrapolating from estimates made by the FDA, replacing with more healthful ingredients all the trans fats that comes partially hydrogenated oils, likely would save upwards of 10,000 lives a year.

Q. So should I avoid every molecule of trans fat?
A. Not necessarily. Trans fat is not a toxin that will kill everyone who eats even a tiny amount. It's worth avoiding foods in which partially hydrogenated oil is down near the end of the ingredient list. ( Ingredients are listed in order of predominance.)

Q. With what ingredients would companies replace partially hydrogenated oil?
A. In the case of margarine, many fried foods, and some baked foods, companies often use canola oil, sunflower oil, and other liquid oils. When a solid fat cannot be avoided, companies might use palm oil, butter ( though rarely because it's expensive), beef tallow, or lard. Ideally, companies would work hard to use less of those saturated fats, perhaps mixing them with a liquid oil.

Q. How are partially hydrogenated oils and trans fat regulated?
A. Currently, the FDA considers partially hydrogenated oils to be safe and does not set any limits on their use or trans-fat content. Nor does it limit the trans-fat content of processed or restaurant foods. However, beginning January1, 2005 the amount of trans fat in a serving of food is listed on food labels.

Q. Which companies are reformulating their products?
A. Ruby Tuesday's and Legal Sea Foods restaurant chains have stopped using partially hydrogenated oil in their deep-fat frying. Kraft/Nabisco, one of teh biggest users of partially hydrogenated oil, is marketing trans-free Triscuits and several varieties of trans-free Oreos. Voortman's Cookies is going in the trans-free variety of Goldfish and plans to reduce trans in other products. In 2002, McDonald's said it would switch to a lower-trans cooking oil, but as of mid 2004 has not done so. Expect many more changes before 2006,as companies try to avoid the stigma of listing trans fat on their labels.

Q. Does any nation ban or restrict partially hydrogenated oil or trans fat?
A. Denmark limits the trans-fat content of foods to two percent of the fat. (Naturally occurring trans fats are exempted from that limit).

Q. Has partially hydrogenated oil always been used?
A, No. Civilization survived without partially hydrogenated oils for eons. It was first used commercially about 75 years ago, but its use became far more widespread beginning in the 1950's. Now it is used in many thousands of processed foods.

Q. I'm avoiding partially hydrogenated oil. What else should I worry about?
A. The main thing is to eat a diet that is based largely on fruits, vegetables, animal-products, and natural occuring fats (avocado, butter, oilve oil, coconut oil. . .). Try to minimize sodium, and refined sugars.
