CLA and cholesterol -

CLA is a type of omega-6 fatty acid. The main dietary sources of CLA are the meat and milk of ruminants, such as cows, goats and sheep. The total amounts of CLA in these foods varies greatly depending on what the animals ate 8.

Most people already ingest some CLA through their diet. The average intake in the US is about mg per day for women and mg for men Keep in mind that the CLA you find in supplements is not derived from natural foods but made by chemically altering linoleic acid found in vegetable oils The balance of the different forms is heavily distorted in supplements.

They contain types of CLA never found in large amounts in nature 12 , The main dietary sources of CLA are dairy and meat from cows, goats and sheep, whereas CLA supplements are made by chemically altering vegetable oils.

The biological activity of CLA was first discovered by researchers who noted that it could help fight cancer in mice Later, other researchers determined that it could also reduce body fat levels As obesity increased worldwide, interest grew in CLA as a potential weight loss treatment. Animal studies suggest that CLA may reduce body fat in several ways In mouse studies, it was found to reduce food intake, increase fat burning, stimulate fat breakdown and inhibit fat production 17 , 18 , 19 , CLA has also been studied extensively in randomized controlled trials, the gold standard of scientific experimentation in humans — though with mixed results.

Some studies indicate that CLA can cause significant fat loss in humans. It may also improve body composition by reducing body fat and increasing muscle mass 21 , 22 , 23 , 24 , However, many studies show no effect at all 26 , 27 , In a review of 18 controlled trials, CLA was found to cause modest fat loss The effects are most pronounced during the first six months, after which fat loss plateaus for up to two years.

According to this paper, CLA can cause an average fat loss of 0. kg per week for about six months. Another review gathered that CLA caused about 3 pounds 1.

While these weight loss effects may be statistically significant, they are small — and there is potential for side effects.

Though CLA supplements are linked to fat loss, the effects are small, unreliable and unlikely to make a difference in everyday life. Many long-term observational studies have assessed disease risk in people who consume larger amounts of CLA.

Notably, people who get a lot of CLA from foods are at a lower risk of various diseases, including type 2 diabetes and cancer 31 , 32 , Additionally, studies in countries where cows predominantly eat grass — rather than grain — show that people with the most CLA in their bodies have a lower risk of heart disease However, this lower risk could also be caused by other protective components in grass-fed animal products, such as vitamin K2.

Of course, grass-fed beef and dairy products are healthy for various other reasons. Many studies show that people who eat the most CLA have improved metabolic health and a lower risk of many diseases. However, the CLA found in supplements is made by chemically altering linoleic acid from vegetable oils.

They are usually of a different form than the CLA found naturally in foods. Supplemental doses are also much higher than the amounts people get from dairy or meat. As is often the case, some molecules and nutrients are beneficial when found in natural amounts in real foods — but become harmful when taken in large doses.

Large doses of supplemental CLA can cause increased accumulation of fat in your liver, which is a stepping stone towards metabolic syndrome and diabetes 35 , 36 , Keep in mind that many of the relevant animal studies used doses much higher than those people get from supplements.

However, some human studies using reasonable doses indicate that CLA supplements may cause several mild or moderate side effects, including diarrhea, insulin resistance and oxidative stress The CLA found in most supplements is different from the CLA found naturally in foods.

Several animal studies have observed harmful side effects from CLA, such as increased liver fat. One review concluded that a minimum of 3 grams daily is necessary for weight loss Doses of up to 6 grams per day are considered safe, with no reports of serious adverse side effects in people 41 , Studies on CLA have generally used doses of 3.

Losing a few pounds of fat may not be worth the potential health risks — especially as there are better ways to lose fat. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

CLA is found in certain foods and available as a fat-burning supplement. This article explains if CLA can help you lose weight. Countless supplements on the market claim to offer a quick way to drop excess weight by suppressing your appetite.

Because CLA is found in animal products, vegans and vegetarians usually have lower levels. CLA is found in dairy products, meat of ruminant animals, and also in industrially hydrogenated vegetable oils and other synthetic products.

All types of fats lipids — whether from animal products, eggs, dairy, oils, nuts, seeds or coconuts — are made up of fatty acids.

Some fats are considered essential fatty acids , because the body cannot produce them on its own, while others are nonessential because the body can synthesize them from other nutrients. The essential fats we need to obtain from our diet include polyunsaturated omega-3 fatty acids found in fish, seafood, eggs and some nuts or seeds and polyunsaturated omega-6 fats mostly found in vegetable oils, nuts and seeds.

Omega-3s are known as being anti-inflammatory while omega-6s are said to be inflammatory. The truth is that we need both types of essential fats to balance our immune, hormone, digestive and nervous system functions, which is why so many low-fat diet risks exist when someone skips out on eating enough healthy fats.

Omega-6 oils are are typically overly consumed by those eating a standard Western diet and therefore dangerous, mostly because they are found in vegetable oils used to make processed junk foods.

Conjugated linoleic acid is one type of omega-6 fat we can afford to eat more of because it tends to act like an omega-3 food in the body, helping lower inflammation and promote other aspects of health.

It also helps turn off hunger by controlling our hunger-hormone called ghrelin and can improve your ability to absorb nutrients. You might find it hard to believe, but it turns out that butter can be a fat-burning food!

A number of studies have found evidence that CLA not only reduces body weight and body fat mass, but may also help increase lean mass in different species. How does CLA help you lose weight? In certain animal s t udies , CLA specifically types 10 and 12 has also been found to lead to increased energy expenditure, increased fat oxidation and browning of subcutaneous white adipose tissue aka white fat.

Supplementation with a CLA mixture equal concentrations of the 10,12 and 9,11 isomers or the 10,12 isomer alone decreases body fat mass, according to results from numerous animal studies.

Of the two major isomers, 10,12 specifically seems to be responsible for the anti-obesity effects of CLA. In human studies, the results for CLA on weight loss have been somewhat mixed, although still promising.

One study found that supplementation of a CLA mixture in overweight and obese people three to four grams a day for 24 weeks decreased body fat mass and increased lean body mass. Other studies have shown similar results and that CLA also has no adverse effects on overall blood lipids, inflammation levels and insulin response in healthy, overweight and obese adults.

One of the possible potential mechanisms by which CLA reduces body fat mass might be that it decreases energy intake or increases energy expenditure. Does CLA reduce belly fat?

The hypothesis is that CLA may be involved in insulin regulation. Conjugated lienoic acid has shown immune-enhancing effects and anticarcinogenic activities in several animal studies. The CLA present in saturated-fat foods might offset the adverse effects of the saturated fat content and benefit everything from blood sugar control, to hormone regulation, to natural cancer prevention.

Lower inflammation is a sign of less free radical damage or oxidative stress that is linked to lower cancer risk. CLA seems to modulate immune and inflammatory responses as well as improve bone mass. Research on the effects of conjugated linoleic acid for preventing breast cancer is somewhat conflicting, but some early research suggests that higher intake of CLA from natural foods is linked with a lower risk of developing breast cancer.

Other study results suggest that it can be beneficial for fighting cancer of the digestive organs and can improve detoxification via healthier liver function , too. Consuming foods high in CLA or taking CLA supplements for 12 weeks seems to improve symptoms and overall well-being in people with seasonal allergy symptoms.

Similarly, some research shows that for people with asthma, CLA might be a natural treatment method for asthma-related symptoms, due to its ability to help control inflammation. Twelve weeks of supplementation seems to improve airway sensitivity and ability to exercise.

Early research suggests that CLA is beneficial for lowering inflammation and therefore autoimmune diseases like rheumatoid arthritis. Taking conjugated linoleic acid alone or along with other supplements like vitamin E benefits those with arthritis by reducing symptoms, including pain and morning stiffness.

Pain and inflammation markers including swelling have been improved for adults with arthritis taking CLA compared to their pre-treatment symptoms or people not taking CLA, meaning CLA can naturally treat arthritis.

Although findings have also been somewhat conflicting, some research shows that taking conjugated linoleic acid alone or along with supplements like creatine and whey protein can help increase strength and improve lean tissue mass.

This is why CLA is often added to some bodybuilding supplements, protein powders and weight loss formulas. According to a report published in The Journal of Food Composition and Analysis , the top food sources of CLA include :. What an animal eats and the conditions in which they are was raised highly affect how much CLA and other fats or nutrients their meat or milk will supply.

The proportion of CLA ranges from 0. In other words, not all beef or dairy is created equal when it comes to supplying us with healthy fats like CLA. Even the season, quality of the soil on the farms and age of the animal affect the CLA content. One study, for example, found that the CLA content in beef and dairy from grass-fed cows is — percent higher compared to grain-fed cows.

Grass-fed beef contains higher levels of CLA and even more omega-3 fats and vitamins too than beef from factory farm-raised animals.

The same goes for dairy products we get from cows, including cream or butter. Butter, beef and cream are nothing to be scared of, as long as you consume the highest quality you can, just like traditional populations have done for thousands of years.

Supposed adverse effects such as oxidative stress, insulin resistance, irritation of intestinal tract and milk fat depression are also examined. It seems that no consistent result was observed even in similar studies conducted at different laboratories, this may be due to variations in age, gender, racial and geographical disparities, coupled with type and dose of CLA supplemented.
