It is unlikely that you will eat an avocado every day, contrary to the findings of a new study.

Statisticians have invalidated American research that claimed that vegetables had reduced the risk of heart disease.

Critics did not consider the changes in cholesterol level & # 39; hilariously impressive & # 39; and claim that they were so tiny that they would have no effect on health.

They also pointed out that the research was funded by Hass Avocado Board, & # 39; the world's largest vegetable producer.

An epidemiologist speculated that the & # 39; silly food study & # 39; was so widespread because it had the impression of & # 39; large avocado & # 39 ;.

His play about the term "large pharma" is a blow at pharmaceutical companies that routinely pump money into studies.

The research, conducted by Penn State University, claimed that avocados reduced the number of oxidized low density lipoprotein (LDL) in overweight adults.

LDL has been shown to constrict blood vessels and limit blood flow through the body.

The paper showed less than 10 percent reduction in & # 39; bad & # 39; see cholesterol – but experts say a 50 percent reduction is needed to promote heart health in obese people.

The researchers were also slammed for performing what is known as "within-group" comparisons.

They took cholesterol levels from the participants before putting them on an avocado-per-day diet and then again at the end of the trial.

Experts say they should have compared the measurements to a control group that did not receive avocados before and after the study to test the true effect of the vegetables on cholesterol.

Why would you mix and eat the avocado STONE, according to scientists

The healthiest part of an avocado can be the well that most people throw away, a new study suggests.

Researchers discovered that an extract in avocado seeds reduced inflammation caused by white blood cells.

They say the findings prove that the extract can be converted into a food ingredient, or even used as a pharmaceutical drug.

However, experts are skeptical and say that the research is at an early stage and that previous studies have shown that if it is consumed in large quantities, the stone can actually be toxic.

Americans eat around seven pounds of avocados every year and the benefits have long been praised, including large amounts of healthy fats and various nutrients, including vitamin K, folic acid and potassium.

Several studies have shown that the fruit has the HDL content & # 39; good & # 39; can increase cholesterol, increase the absorption of nutrients from other foods and can help with weight loss.

The yellow-green meat inside is eaten everywhere, from salads to toast, but the skin and seeds are generally thrown away.

A study conducted by Penn State in 2013, it was found that Aztecs and Mayans would heat or cook the seed to treat a number of diseases, including diabetes, gastrointestinal problems, and parasitic infections.

Another study from Nigeria in 2009 it appeared that the pit extract was historically used in the African country to control high blood pressure.

However, research has shown that the well can be toxic.

A Mexican from 2013 study discovered that high doses of an extract from the seed were harmful to mice, although it did not cause genetic damage.

And a 1988 study from Israel showed that avocado oil increased fat buildup in the livers of rats.

Gideon Meyerowitz-Katz, an epidemiologist who obtained a PhD at the University of Wollongong in Australia, adjusted the findings after excluding data from the group.

He discovered that the avocado & # 39; s had reduced LDL levels by about 4% – a fraction of the 10% originally reported by the researchers.

LDL is only an important type of cholesterol, lipoprotein with a high density (HDL) is another.

HDL is sometimes called good cholesterol because it promotes blood flow and reduces the risk of heart disease

But the avocado study, published in The Journal of Nutrition, made little mention of how the vegetables changed the HDL levels.

This raises suspicions, because a decrease in HDL could indicate an increased risk of heart problems.

The study, which looked at 45 overweight people, was also intended to control triglycerides – a combination of fats that are used as an indicator of the risk of heart disease.

But it did not mention this in their findings, which again raised the eyebrows of critics.

Dr. Meyerowitz-Katz said on Twitter: & The results were not hilariously impressive. Avocado & # 39; s lowered LDL (& # 39; bad & # 39;) cholesterol a tiny bit, and also slightly changed the levels of a few antioxidants.

& # 39; For reference: the LDL reduction here is <10 percent relative to the baseline value, while guidelines usually argue for a reduction of 50 percent if possible.

& # 39; So there was a minimally significant reduction in & # 39; bad & # 39; cholesterol, but here's the funny part – it might not be important at all.

& # 39; This is because, like many of these crazy food studies, the researchers do much of the so-called & # 39; inside group & # 39; comparisons.

& # 39; In short, this means comparing the avocado diet at the end with the avocado diet at the beginning, instead of the control groups they had. This makes the result a bit useless due to, among other things, regression to the average. & # 39;

He said it was & # 39; absurd & # 39; was to suggest that the small changes in cholesterol may be beneficial to normal people in daily life.

Dr. Meyerowitz-Katz added: & # 39; Remember that these were not (as the headlines suggest) people who just added avocados to their diet.

& # 39; These were people who eat carefully controlled, formulated diets centered around avocados.

& # 39; It is absurd to suggest that you could take these complex, indoor study diets and apply the results to people who wonder what is a little healthier.

& # 39; This research was funded by the Hass Avocado Board, the organization for the most grown avocado in the world (for whom the senior study author also works). In other words, BIG AVOCADO. & # 39;

The Penn State study took 45 obese and overweight adults and divided them into three groups.

Each adult participated in five weeks of three separate diets, in a randomly assigned order.

One followed a low-fat diet, another a moderately fat diet, and the third a moderately fat diet that included one avocado per day.

Participants in the last group compensated for the lack of avocado & # 39; s by eating extra healthy fats that are designed to mimic the amount of fatty acids in avocado & # 39; s.

WHAT IS HIGH CHOLESTEROL?

Cholesterol is a fatty substance that is vital for the normal functioning of the body.

But too much can cause it to accumulate in the arteries, limiting blood flow to the heart, brain and the rest of the body.

This increases the risk of angina, heart attacks, strokes and blood clots.

Cholesterol is made in the liver and is carried by proteins in the blood.

The first – high-density lipoprotein (HDL) – transports cholesterol from cells to the liver where it is broken down or passed on as waste. This is & # 39; good cholesterol & # 39 ;.

& # 39; Bad cholesterol & # 39; – low density lipoprotein (LDL) – carries cholesterol to cells, with excessive amounts that are subsequently incorporated into the vessel walls.

High cholesterol can be genetic, but it is also linked to a diet rich in saturated fat, as well as smoking, diabetes, high blood pressure and a family history of stroke or heart disease.

Blood cholesterol is measured in units called millimoles per liter of blood, often abbreviated to mmol / L.

The overall level of a healthy adult should be 5 mmol / L or less, while their LDL level should not exceed 3 mmol / L. An ideal level of HDL is higher than 1 mmol / L.

Cholesterol can be reduced by eating a healthy, low-fat diet; do not smoke; and exercise regularly.

If these do not help, cholesterol-lowering drugs such as statins may be prescribed.
