High-Fat Diets Protect During Heart Attack?

As long as I am “somewhat ” aware of nutrition  I never advised patients  against meat because of the fat-content.

I never propagated an exclusive American steak diet!

I am not aware of any proof that “natural saturated fat" would harm, but it has become a tremendous dogma.

Animal experiments may have been done [at least partially] with “chelev”, the fat the Tora forbids the Jew to eat and which Jewish tradition considers to be unhealthy [Ramban’s commentary on chelev]

When I asked a leading -

 

WHO sponsored !!-

 

research centre for lipids [atherosclerosis] what kind of fat the animals were fed [and if chelev could have been an important part of the diet] the leader of the project could not answer me.

[ margarine and all the various oils [except olive oil , sesame oil and a few more exceptions like proper coconut oil and proper red palm oil [ Indonesia] are not saturated but highly damaging]

If you really get confused by all the -ever changing- medical dogmas then look what traditional diets were used[not the last 50 or 100 years ,maybe]

High-Fat Diets Protect During Heart Attack?

(Ivanhoe Newswire) -- A new study conducted by researchers at the University of Cincinnati (UC) illustrates that short-term, high-fat "splurges" within one's diet could actually bring about cardioprotective properties during a heart attack.

Lauren Haar, a doctoral student in the Systems Biology and Physiology Graduate Program, discovered that short-term, high-fat feeding in animal models led to cardioprotection against myocardial infarction (MI or heart attack) and resulted in less cardiac tissue damage.

"Previous clinical studies have supported the idea that certain patients with high serum cholesterol levels have better survival rates when their heart fails after cardiac ischemic injury than those with lower cholesterol levels, but the reason for this is unclear," Haar was quoted as saying. "Previous research using a heart failure animal model paired with chronic high-fat feeding showed improvement in heart function and modulation of cardioprotective gene profiles. However, there are very few studies geared toward understanding the acute effect of these diets on MI. We wanted to see if the same was true in models of acute high-fat feeding paired with simulated heart attacks."

For the study, researchers fed one group of mice a high-fat diet (60 percent of the calories coming from saturated fat) for two weeks or less. A second group received the high-fat diet for six weeks, and a control group received a regular, grain- and vegetable-based diet.

"We then induced heart attack in all groups and assessed the cardiac function and extent of injury to the tissue," Haar said. "Our results showed that injury in mice fed a high-fat diet acutely (two weeks or less) was reduced by 70-percent when compared to the groups fed on a high-fat diet for six weeks or fed on a control grain- and vegetable-based diet."

She says there was no cardioprotection seen in the six-week group, representative of the notion that short-term splurges are in fact key, and the effects of continual high-fat feeding, including obesity and diabetes, do not contribute to cardioprotection.

"In addition, animals fed a high-fat diet for 24 hours and then returned to a control diet for 24 hours prior to heart attack experienced a prolonged or 'late phase' protection against injury," she adds. "This shows that acute -- or short-term -- high-fat feeding in animal models does preserve cardiac function."

Haar adds that additional studies are currently in the works to uncover the factors that start this response in the body.

"This could mean great things for patient care if we can find the mechanisms that come into play to cause this cardioprotection," she said, adding that this could be a way to "pre-treat" patients at risk of heart attack. "This also may show that, while it's important to eat right, not all 'bad' foods -- like red meat -- should be avoided all of the time. This could change the way we view nutrition and dietary recommendations."
