  • Stomach aortic calcification (AAC) causes calcium deposits within the stomach aorta, a big artery that provides blood from the center to the stomach organs and decrease physique.
  • Folks with AAC have an elevated danger of cardiovascular occasions corresponding to coronary heart assault and stroke.
  • A brand new research reveals {that a} food regimen excessive in flavonoid meals like black tea, apples, and cruciferous greens might stop AAC and shield coronary heart well being, significantly amongst ladies.
  • The findings point out that older ladies who consumed extra flavonoid meals had been 36% much less more likely to have AAC in comparison with those that consumed fewer flavonoids.
  • Extra analysis is required to find out whether or not flavonoid-rich meals may stop calcification in different arteries.

May a cup of tea or an apple a day actually hold the physician away? Perhaps not — however new analysis suggests {that a} food regimen excessive in flavonoids corresponding to tea, fruits, and cruciferous greens might decrease your danger of coronary heart illness.

A current research from researchers at Edith Cowan College (ECU) in Australia discovered that older ladies who consumed excessive ranges of flavonoids from plant-based meals sources had been much less more likely to have in depth stomach aortic calcification (AAC).

AAC occurs when calcium deposits construct up in your stomach aorta, a big artery that provides blood out of your coronary heart to your stomach organs and decrease physique.

Folks with AAC have an elevated danger of heart problems, corresponding to coronary heart assault and stroke. They’re additionally extra more likely to develop late-life dementia.

“This is only one of many, many research which have proven a discount in cardiovascular danger with consuming extra of a plant-based food regimen that’s wealthy in flavonoids,” Janice Friswold, RD, LD, a registered dietitian and diabetes educator at College Hospitals in Cleveland, OH, who was not concerned within the new research, instructed Healthline.

“Some research on flavonoids have additionally proven different advantages, corresponding to discount of most cancers danger or cognitive decline, so there’s nothing however great things to say about this stuff.”

The ECU research was lately printed within the journal Arteriosclerosis, Thrombosis, and Vascular Biology, which is a journal of the American Coronary heart Affiliation.

Flavonoids are a sort of plant compound present in fruits, greens, spices, tea, and different plant-based meals. They’re antioxidants that assist shield cells from harm attributable to oxidative stress.

Scientists have recognized greater than 6,000 forms of flavonoids, that are labeled into 12 major teams.

Six of those teams are present in frequent meals:

“Consuming a food regimen excessive in flavonoid-rich meals is absolutely vital,” Friswold stated.

“I typically don’t suggest that individuals take [flavonoid] dietary supplements as a result of we all know there’s over 6,000 totally different phytochemicals within the flavonoid group, and we’ve remoted a couple of of them, however who is aware of which is the magic mixture.”

As an alternative, well being and vitamin specialists like Friswold encourage individuals to “eat the rainbow” by consuming a wide range of fruits, greens, and different plant-based meals of various colours.

Edith Cowan researchers evaluated the consuming habits of 881 older white ladies enrolled within the Perth Longitudinal Research of Ageing Girls (PLSAW) to learn the way flavonoid consumption may have an effect on cardiovascular well being.

These ladies had been typically wholesome and had no prior historical past of heart problems.

The researchers requested contributors to finish food-frequency questionnaires to report how typically they consumed sure meals and drinks through the previous yr.

The researchers additionally collected details about contributors’ physique mass index (BMI), smoking historical past, bodily exercise, and whether or not they had obtained a prognosis or had been taking treatment for sure well being situations, corresponding to diabetes, persistent kidney illness, hypertension (hypertension), or excessive ldl cholesterol.

After controlling for these components, the researchers discovered that older ladies with greater whole flavonoid consumption had been 36% much less more likely to have in depth AAC than these with decrease flavonoid consumption.

Black tea was the principle supply of flavonoids in contributors’ diets. Girls who drank 2–6 cups of black tea per day had been 16–42% much less more likely to have in depth AAC than those that drank none.

Amongst contributors who didn’t drink black tea, flavonoid consumption from different dietary sources was nonetheless linked to a decrease danger of AAC.

Though the findings counsel {that a} flavonoid-rich food regimen has well being advantages, the research does have limitations.

For example, the researchers evaluated a comparatively wholesome and racially homogeneous group of ladies and solely requested about them their consuming habits over the previous yr slightly than their lifetime.

It may be difficult for many individuals to precisely recall their consuming habits, particularly over longer durations.

“What we don’t know is whether or not contributors have been following the identical food regimen for years or in the event that they was once on a special food regimen and have lately turn into more healthy,” Dr. Johanna Contreras, a heart specialist at Mount Sinai Hospital in New York, NY, instructed Healthline.

“My query is — if I modify my food regimen to eat wholesome beginning tomorrow, will I get this profit? Or is that this a profit that contributors had as a result of they’ve been consuming like that for a very long time?”

The research additionally targeted solely on AAC slightly than evaluating calcification in different arteries.

“Simply because an individual has aortic calcification doesn’t imply they’ve calcification of their major coronary arteries,” Friswold stated.

“So these days, we’re doing a CT calcium rating, which appears to be like on the three major arteries to see if there’s calcification there.”

Plant-based flavonoid meals are wealthy in healthful vitamins like antioxidants and fiber and may additionally assist combat irritation.

The brand new research from ECU is just one of many research highlighting the potential advantages of consuming a food regimen containing loads of flavonoid-rich, plant-based meals.

For instance, the authors of a 2013 research adopted 93,600 wholesome ladies from the Nurses Well being Research II over 18 years and located that these with a excessive consumption of anthocyanins had a decrease danger of coronary heart assault.

The authors particularly highlighted the obvious advantages of blueberries and strawberries, that are wealthy in anthocyanin.

And lately, in one other new research printed in Neurology, researchers linked antioxidant flavanol consumption to slower reminiscence decline.

Contributors with the very best flavanol consumption consumed a median of 15 milligrams every day, roughly equal to 1 cup of darkish leafy greens.

The American Coronary heart Affiliation (AHA) encourages individuals to eat all kinds of plant-based meals, together with:

  • 2.5 servings of greens per day
  • 2 servings of fruit per day
  • 6 servings of grains per day, with entire grains most well-liked over refined grains

Friswold stated it may be useful to position much less emphasis on which kind of protein you’re going to devour at every meal and focus as an alternative on what you’re going to have for vegetables and fruit.

The AHA additionally encourages individuals to apply different wholesome consuming habits by selecting lean protein sources and limiting consumption of saturated fats, trans fat, and added sugars.

Getting sufficient sleep, avoiding smoking, and exercising often are additionally vital for decreasing the chance of heart problems and lots of different persistent situations.

“I all the time inform sufferers that if you already know you’ve got danger components for coronary artery illness or you’ve got calcified plaques within the arteries, enhance your food regimen and hold shifting,” Contreras stated.

“Good food regimen and train are crucial.”

New analysis builds on a big physique of proof in assist of the various well being advantages of flavonoids.

The ECU research discovered an affiliation between the consumption of flavonoid-rich meals like black tea and apples and improved coronary heart well being amongst older ladies.

Nonetheless, the research targeted primarily on stomach aortic calcification (AAC), which implies extra analysis on how flavonoids may cut back calcification in different arteries continues to be wanted.
