A diet rich in carotenoids may boost women’s health

  • Researchers reviewed studies looking at the effects of carotenoids on women’s health outcomes.
  • They found that a higher intake of carotene may reduce the risk of developing multiple health conditions.
  • They concluded that given the high potential for help and low potential for harm, approaches that target carotenoid intake in women may be beneficial.

Although women tend to have a longer life span than men, they also have more health conditions.

Likewise, women tend to have more Strong immune systems Of men, they also represent 80% for autoimmune conditions.

Many neurodegenerative diseases, such as Alzheimer’s disease And the Age-related macular degenerationmore common in women than men.

some Research It suggests that these differences may arise from different levels of exposure to oxidative stress from lifestyle factors and intrinsic factors such as endocrine differences.

If this is the case, then antioxidants and anti-inflammatory elements in the diet may be a benign way to reduce oxidative and inflammatory stress and thus improve health.

Researchers recently reviewed studies looking at the effect of diet on autoimmune disease in women.

They found that eating pigmented carotenoids may be important for preventing vision and knowledge loss.

The review was posted on Nutritional Neuroscience.

“This review builds on decades of previous work that conclusively shows that a diet rich in fruits and vegetables – many of which contain carotenoids, which are responsible for some of the bright colors of fruits and vegetables – is associated with healthy aging, longevity, and a lower risk of chronic disease.” Amy Keeler Ph.D.D., assistant professor in the Department of Endocrinology, Metabolism, and Diabetes at the University of Colorado Denver, and was not involved in the review.

“The reasons for this may be multifactorial, but the possible reasons why carotenoids are beneficial is because of their antioxidant and anti-inflammatory activity,” she added.

In the review, researchers note that low bone mineral density can be detected in females in their 30s Accelerates after menopause.

Studies have shown that some carotenoids may slow bone loss.

These include lycopene – found in TomatoesBeside beta-carotene and lutein (L), and zeaxanthin (Z) which is found in leafy greens and eggs.

The researchers also note that higher levels of L and Z are associated with a lower incidence and prevalence of eye lens darkening And the Age-related macular degeneration (AMD).

Previous research indicates that carotenoids Hinder Deposition of beta-amyloid in the brain and slowing down fibrogenesis, both of which are linked to dementia.

They further indicated that L and Z Increase cellular efficiency and improve cognitive function in childrenAnd the youthsAnd the the elderlyand those who have Cognitive impairment.

Other research shows that L and Z are essential for infant growth. One study found that women in the highest quartile of L and Z intake had children of their own 38% lower risk Visual impairment when assessed after three years.

The researchers added that other studies show that higher levels of carotenoids in the blood are also linked to a lower risk of:

When asked about pigmented carotenoids like L and Z that may improve health, Professor Billy Hammond One of the study authors in the University of Georgia College of Behavioral and Brain Sciences said Medical news today:

“The old adage that you are what you eat is actually true. What you eat affects the composition of your brain and the chemicals called neurotransmitters and hormones that are involved in its function.”

He explained that the brain is made up of about 60% fat, which makes it particularly vulnerable to oxidative stress. To counteract any potential harm, our brains typically contain fat-soluble antioxidants from foods like eggs and leafy green vegetables to protect the brain. Problems arise because modern diets tend to contain less of these antioxidants than is required.

While carotenoids consumed from food may improve health outcomes, Research It indicates that supplemental versions of these nutrients may not yield the same effect. This is because individual nutrients may not affect the body in the same way that they are eaten as part of a fruit or vegetable.

With that in mind, Wendy L. Bennett, MD. , an associate professor at Johns Hopkins University School of Medicine, was not involved in the study, said MNT:

Take vitamin E or beta-carotene supplements Will not Prevent or delay the onset of AMD. The same is likely to apply to vitamin C and multivitamins (Centrum Silver), [as found in a clinical trial]. “

There is no evidence for other antioxidant supplements, such as lutein and zeaxanthin. She added that vitamin supplements may have adverse effects, and clear evidence of their benefit is needed before they can be recommended.

The researchers concluded that, given the higher potential for help and lower potential for harm, approaches that target L and Z intake in women may be beneficial.

When asked about the study’s limitations, Dr. Keeler noted that future work should clarify the mechanisms underlying the clinical findings mentioned in this review.

Dr Hammond added that it is very difficult to link a single intake like vitamin E to a complex end point that develops over an entire lifetime. he added:

“Most degenerative diseases, such as dementia, are as complex as aging itself and involve so many exposures that matter little at a given time but so much when aggregated over 50 years. Imagine, for example, that a particular food ingredient reduces risk by one percent annually. [It may seem small, however] However, one percent per year for 70 years, that means a reduction in risk of about 30 percent, which is huge.”

Dr. Bennett noted, however, that the researchers did not conduct original research, which means that their synthesis and summary of evidence may be subject to bias.

When asked about other nutrients that may have a protective effect on women’s health, Dr. Keeler said:

In addition to carotenoids, flavonoids are also responsible for the colors of fruits and vegetables. Our team is studying the potential of the flavonoid, (-)-epicatechin, which is found in commonly consumed foods such as chocolate and tea. This compound improved vascular health in our studies. As women lose protection from cardiovascular risk after menopause, supporting vascular health through targeted bioactive nutrients may aid women’s health in old age.”

Dr Hammond added that general lifestyle factors such as getting more exercise and eating a healthy diet are also key to improving health. “It’s common to think of single ingredients of diet-like drugs or a ‘pill per patient,'” he said. “While supplementation is sometimes a good strategy, improving the diet is your best approach first.”
