Maltese heart, but not heart disease: Researchers in the United States and Finland have discovered a strong relationship between malt, the heart’s main protein, and heart health.
A new study by researchers at the University of Illinois and the National Institute on Alcohol Abuse and Alcoholism (NIAAA) in collaboration with the Finnish Heart Institute in Helsinki shows that people with a higher consumption of the protein in their diet had a higher risk of developing heart disease.
“It is really exciting,” said co-author Dr. John Wettlaufer, a cardiovascular disease researcher at the NIAAA.
“Our findings show a strong association between the protein malt and cardiovascular disease risk.
This is really important news for people who are considering going to the doctor for a diagnosis.”
Maltose, the key fatty acid found in milk and cheese, is made from a single protein.
When it is eaten as a snack, it is known as “maltodextrin.”
But when it is ingested in large amounts, like in milk, cheese or butter, the protein breaks down into a mixture of the amino acid leucine and glutamine.
The amino acids leucosine and gamma-glutamylcarnitine are essential for cell growth and for muscle protein synthesis.
In people who consume more of these amino acids, they are linked to an increased risk of heart disease and stroke.
The study, published in the American Journal of Cardiology, looked at the relationship between three factors: a high intake of protein in a diet, the frequency of consumption of maltodextrins, and the age of participants.
The researchers found that people who were consuming the most maltodexterins had a 44% higher risk for developing heart diseases.
The frequency of maltose consumption in the study also increased the risk.
“There was a positive relationship between the consumption of these two nutrients and heart outcomes,” said Dr. James R. Avent, a cardiologist and senior investigator at the National Institutes of Health’s National Institute of Diabetes and Digestive and Kidney Diseases.
“We didn’t look at the age.
What we found is that maltose was associated with a 50% higher rate of developing atherosclerosis.
It was a very strong relationship.”
In addition, people who drank the most amount of maltodes also had a 55% higher likelihood of developing coronary artery disease.
The authors said this relationship was strongest among those who were in their 50s or older.
“This is very interesting,” said Wettltaufer.
“For the first time, we’ve identified the key role of malt and the risk of cardiovascular disease.”
Researchers also found a link between the number of meals people ate per week and the increased risk.
People who consumed at least four meals per week had a 38% higher chance of developing cardiovascular disease.
This link could be because the study participants were not consuming enough maltodexylbutyrate, which is produced in the liver when people consume large amounts of alcohol.
The other key finding was that the frequency and duration of the maltodeoxylic acid (MDA) intake also had an effect.
“When you’re consuming maltodeoxymethionine, it’s metabolized in the body.
But when you’re drinking, it doesn’t have to be metabolized,” said study co-lead researcher Dr. Sarah P. Burdett, a senior nutritionist at the Diabetes Center of the Mayo Clinic.
“The MDA can get converted into MDA-glucuronide, which in turn can get into the blood stream.
That means you can get a blood clot.”
Dr. Burt says that it is not known whether MDA is involved in the formation of the clot, but she said this is an important finding because it might be linked to other risks.
“If you’re in the middle of your 30s or 40s and you consume a lot of MDA, it might increase your risk of having a heart attack,” she said.
“So the fact that you have a higher MDA intake might mean you’re more likely to develop heart disease later on in life.”
The research was funded by the National Heart, Lung, and Blood Institute and the Department of Health and Human Services, Office of Research and Development, under grants R01 DK-187723 and DK-0790432.
