El cacao or el té verde pueden proteger al organismo contra el estres cotidiano

Una bebida de cacao or de tea verde, rich in flavanols, pueden proteger la vasculatura del organismo contra el estresAccess the new research publication of the journal 'Food and Function'.

Food choices during stressful times can influence its impact on cardiovascular health. Flour Studying at the University of Birmingham (United Kingdom) He discovered that fatty foods can negatively affect vascular function and oxygen supply to the brain, while flavanol compounds, abundant in cocoa and green tea, can protect vascular function during daily stress.

Now, the same group of researchers has found that consuming flavanol-rich cocoa along with a fatty meal can offset some of the effects of fatty foods and protect the vascular system from stress.

Dr Catarina Rendeiro, associate professor of nutritional sciences at the University of Birmingham and lead author of the study, confirms: “Sabemos que cuando las personas están estresadas tenden a consumir alimentos ricos en grasas los alimentos grasos pueden prejudicar la recovery vascular del organismo tras el estres. In this study, we wanted to see if adding a flavanol-rich food to a fatty diet would reduce the negative effects of stress on the body.

Rosalind Baynham, a first-rate author, obviously flavanols are a type of compounds found in various fruits, vegetables, tea, and dried fruits. las bayas and cacao include no process. Flavanols are known to be beneficial for health, especially for regulating blood pressure and maintaining cardiovascular health.

“We take a group of healthy young people and give them two buttermilk croissants for breakfast with 10g of buttermilk salad, 1.5 slices of cheddar cheese and 250ml of whole milk and a high-flavanol or beida cocoa drink. flavanols with cocoa –explica–. they did not express an unequivocal opinion in their answer”.

For 8 minutes or 8 minutes, check the mind of the math, for example, activate the cardiovascular system and activate the oxygenation of the frontal lobe (CPF). Vascular function was also measured by flow-mediated brachial dilatation (DMF), a predictor of future cardiovascular risk. “Esta tarea de estres causes significant increases in heart rate and arterial pressure, similar to the stress encountered in everyday life,” he said.

Importance of flavanols

Make 12g of cocoa and 250ml of flavored instant cocoa. There were no flavanols to alkalinize the cocoa to reduce the total amount of flavanols to 5.6 mg; y el polvo de cacao con alto contenido ve flavanoles era un polvo non alcalinizado, que proporcianaba 695.0 mg de flavanoles to ración. Alkalinization is a process traditionally used in making chocolate to enhance its flavor, but unfortunately, it reduces the amount of flavanols.

The team confirmed that consumption of low-flavanol fatty foods during mental stress reduced vascular function (1.29% DMF) and persisted for up to 90 minutes after the stressful event ended. The results also showed that drinking flavanol-rich cocoa was effective in preventing the deterioration of vascular function after stress and fat consumption.

At 30 and 90 min after the stress period, flow-mediated brachial dilatation was significantly greater compared with flavanol-rich cocoa. The team also found in previous work that consumption of high-fat foods reduces brain oxygenation in the prefrontal cortex during stress. Sin embargo, los flavanoles del cacao no mejoraron la oxygenación cerebral ni influyeron en estado de ánimo.

Dr. Rendeiro emphasizes that “this study shows that drinking or eating foods rich in flavanols can be used as a strategy to reduce some of the effects of bad food choices on the vascular system. This can help us make more informed decisions about what we eat. and bebemos during periods of stress,” he added.

So consumers are advised to look for minimally processed cocoa powder in the supermarket, but if cocoa isn't their favorite drink, there are other ways to get a higher dose of flavanols, such as green tea, black tea and berries. . The latest published guidelines for the intake of flavanols recommend between 400 and 600 mg per day.que pueden conseguirse, for example, consume two cups of black or green tea, or a combination of berries, apples and high-quality cocoa.

Jet Veldhuijzen van Zanten, professor of biological psychology at the University of Birmingham and author of the study, adds that “modern life is stressful and the impact of stress on our health and economy is well documented, so any change should protect us from some of the symptoms of stress. marcar una verdadera diferencia.” concluded.
