New York, Jan 3, 2018: A new method of calculating so-called “bad cholesterol” levels has the potential to do away with the need to fast before blood is drawn for such screening, say researchers.

The study, published in the journal Circulation, suggests that the new method is more accurate than an older method in people who did not fast before the cholesterol test.

The new method for calculating LDL, or low-density lipoprotein, was developed by Seth Martin and colleagues at Johns Hopkins University School of Medicine in the US.

“Although the new LDL calculation method is a bit more complex, the beauty is that it can be performed using information that is already collected in the blood sample for the standard lipid profile and automated in the lab’s computer system to give a more accurate result,” Martin said.

“Since nonfasting samples are now accurate, it’s more convenient for patients because they can come in anytime and don’t need to return for a second appointment if they have eaten,” Martin added.

For the study, the researchers compared the accuracy of the new LDL calculation method with the Friedewald method, developed in the late 1970s when patients fasted or did not fast.

The Friedewald method was earlier shown by Martin and colleagues to underestimate LDL cholesterol levels, particularly in people with high triglycerides.

Triglycerides are fatty acids that tend to be higher in people with obesity and diabetes and that increase after eating.

The physicians did their comparison using data already gathered in a clinical repository.

In their final analysis, the researchers found that approximately 30 per cent of the nonfasting participants had greater than 10 milligrams per decilitre inaccurate cholesterol measurements using the Friedewald method compared with only three per cent error from the actual measured value with the new method.

The new test does not take any longer to provide results to physicians and patients, and the cost is the same to administer, the study said. (IANS)

Fat is an important part of any balanced diet but the type of fat you eat matters the most particularly when it comes to cholesterol level so make sure you are avoiding the ones that is causing health problems.

Manoj Acharya, Food Consultant at Zappfresh and Mehar Rajput, Nutritionist and Dietician at Fitpass tells us about the foods that are full of trans fats and are harmful to our health.

* Cakes, pies and cookies (especially with frosting) : Most cakes and cookies mixes list 0 gm of trans fat on the label. But there is a catch. Manufacturers can list 0 gm if the trans fat content is under 0.5gm. Those small amounts add up when you eat multiple serving of sweets that too with frosting. An average serving of frosting contains 2 gm of trans fats, plus the same amount of sugar.

* Biscuits: This one surprises a lot of people. Biscuits contain 3.5gm of trans fats. It also contains over half of the daily recommendations of sodium.

* Margarine: Most margarine makers have removed trans fats from their ingredients. But you still must check. The few that still contains trans fats as high as 3gm per servings.

* French fries: You need to be cautious about where they fry your French fries in Vanaspati ghee or hydrogenated fat. Though certain food chains decided to turn healthier by becoming trans-fats free, you must care about it. But if you are cautious about health, you shouldn’t be having French fries.

Cholesterol -- a molecule normally linked with cardiovascular diseases -- may also play an important role in the onset and progression of Alzheimer's disease, researchers have found.

* Fried chicken: Just like French fries you need to be sure that your fried chicken has not been fried in hydrogenated oil. Same goes for fried fish.

* Frozen foods: People who are perpetually busy tend to pick up frozen meals from the supermarket. They are most likely to have trans-fat in them as they need to be kept preserved for a longer time.

* Ice creams and Indian savouries: It contains 0.5 gm of trans fat per servings. But if you read the ingredients list, the listing of partially hydrogenated oil is missing. That may be because there are naturally occurring trans fats in fat-containing dairy products which are not as dangerous as the manufactured trans fats. These products are high in calories, so one should still keep a check on their intake. Besides this, all the India savouries like Gulab Jamun, Gujhia, Laddo and Kachouri.

* Popcorns: There is a good way and bad way to eat popcorn. The snack itself is a healthy whole grain packed with fibre. It is the extra add-on that gives it that trans-fat flag. Plain popcorn is fine but when you add butter to it(which is not real butter ), it made it loaded with trans fats with no other health benefits in it.

* Non-dairy creamers: For coffee lovers, non-dairy creamers can become an integral part of their morning. Over time, however, they can also add trans-fat to your diet. One serving contains 0 gm trans-fat, yet, for some flavours, partially hydrogenated oils are the second or third ingredients listed, which can add up if you drink multiple servings in a day. So keep a check on the portion size.

* Sandwich spreads: Think twice before next time when you go out to have your sandwich with spreads if you got cholesterol concern. Trans fat occur naturally in some food like meat and While it’s not as concerning as the artificial kind added through hydrogenated oil, it doesn’t do you much good, either. Those who have heart disease, it is recommended to choose lean meat as much as possible as well as low fat or fat-free dairy products. (IANS)
