Increased intake of fish can boost good cholesterol levels

Increasing the intake of fatty fish increases the number of large HDL particles, according to a recent study completed at the University of Eastern Finland. People who increased their intake of fish to a minimum of 3-4 weekly meals had more large HDL particles in their blood than people who are less frequent eaters of fish. Large HDL particles are believed to protect against cardiovascular diseases. The results were published in PLOS ONE.

The consumption of fish has long been known to be beneficial for health; however, the mechanisms by which fats and other useful nutrients found in fish work in the human body are not fully known. This new study carried out at the UEF provides new information on how the consumption of fish affects the size and lipid concentrations of lipoproteins which transport lipids in the blood. The study participants increased their intake of fatty fish in particular.

It was observed that a higher intake of fish increased the number of large HDL particles and lipids contained in them. Population-based studies have shown that HDL cholesterol — also known as good cholesterol — and large HDL particles are efficient in sweeping extra cholesterol off artery walls. Large HDL particles have been associated with reduced risk of cardiovascular diseases, whereas small HDL particles may even have opposite effects.

Positive changes in lipid metabolism were observed in persons who increased their intake of fish most, i.e. in persons who ate at least 3-4 fish meals per week. The study participants ate fatty fish such as salmon, rainbow trout, herring and vendace. No added butter or cream was used in the preparation of fish. The study doesn’t give answers to whether a similar effect would have been observed had the study participants mainly eaten low-fat fish such as zander and perch. Low-fat fish may have other health benefits such as lowering of blood pressure, which was observed in an earlier study carried out at the UEF.

State-of-the-art metabolomics was used in the study, enabling for instance a very detailed analysis of lipoprotein particles. The analyses were carried out by the university’s NMR Metabolomics Laboratory. Traditionally, cholesterol is divided into “bad” LDL cholesterol and “good” HDL cholesterol, but this method allows the investigation of a total of 14 different particle classes. “People shouldn’t fool themselves into thinking that if their standard lipid levels are OK, there’s no need to think about the diet, as things are a lot more complicated than that. Soft vegetable fats and fish are something to prefer in any case,” Postdoctoral Researcher Maria Lankinen says.

However, the researchers emphasize that a dietary approach to the treatment of increased overall and LDL cholesterol levels is important. The findings are well in line with the Finnish nutrition recommendations encouraging people to reduce the consumption of red meat and to increase the consumption of fish and other sea foods.

    The caliper is *great* and the myotape can be useful, too. Both are easy to use.

    Some reviews have said the caliper is too simple to be effective, but they are mistaken. Their problem is not with the caliper, but the way they are using it (see more below). This product is recommended by the pros, and there is no reason to pay any more.

    Caliper: It’s a little tough to get a consistent reading, but with practice it gets easier. The product has a great “click” feature so you can never push too hard. Do not use the instructions or the chart that comes with the product, however, as it will decrease the accuracy and consistency of your body fat measurements. A much more reliable method is to use the internet (see below).

    Myotape: Very easy to use and good compliment to caliper.

    How to maximize this product using the internet:
    1) EXRX dot net has a page which lists the skinfold sites to measure under /Testing/BodyCompSites.html and a calculator page under /Calculators/BodyComp.html that will give you the appropriate fat %. I use the 3 site method since the 7 site method requires the help of another person, and it’s not necessarily that much superior, anyway.
    2) gain-weight-muscle-fast dot com /body-tape-measurements.html lists further regions to measure
    3) Each time you measure (weekly, monthly, etc), do it the same time of day in the same exact spot. This will help minimize error.

    Note, the instructions which come with the caliper do work, it’s just that it isn’t the best method, which is why some fitness freaks were complaining. Consistency across measurements is the most important thing when measuring body fat, and the suprailiac is terribly tough spot to hit consistently. Veer just a little off and the reading will change. But if you use the other method I listed, these problems will be alleviated. Also, the 3 site method is more accurate, with minimal additional effort.

    Amazon Verified Purchase(What’s this?)
    This review is from: Accu-Measure Fitness 3000 Personal Body Fat Tester (Sports)
    This little plastic product is so quick and easy to measure your body fat percentage that you almost feel like it can’t be that accurate.

    But just for kicks I had my body fat measured with one of those fancy electronic machines several times before using the Accu-Measure calipers.

    The average of three readings for the electronic device was 26% body fat while the Accu-Measure showed 25.5%. Not bad considering this product is a whole heck of a lot CHEAPER than the electronic body fat machines.

    I’m trying to get my body fat down to single digits and these Accu-Measure calipers will help me track my progress. VERY affordable and they REALLY work!
