Eating a diet rich in leafy greens may reduce the risk of cognitive decline, according to a study by Rush University Medical Center. More than 900 older adults were followed by the researchers for an average of 4.7 years. The study found that those who consumed the most servings of leafy greens had a slower cognitive decline rate than those who consumed fewer servings. The researchers believe that the high content of Vitamin K in leafy greens may be one reason for the positive effect on cognitive decline. Leafy greens are already recommended as part of a healthy diet by health authorities.

New Study Finds Leafy Greens Can Reduce Risk of Cognitive Decline

A new study has found that a diet rich in leafy greens may significantly reduce the risk of cognitive decline in older adults. The study, which was published in the journal Neurology, followed more than 900 older adults for an average of 4.7 years and found that those who consumed the most servings of leafy greens had a slower cognitive decline rate than those who consumed fewer servings.

The Study

The study, conducted by researchers at Rush University Medical Center, measured the cognitive abilities of participants using a series of tests that assessed memory, spatial reasoning, and other skills. The researchers also collected data on the participants’ dietary habits, including their intake of fruits and vegetables.

After adjusting for other factors that could affect cognitive decline, such as age, education, and physical activity, the researchers found that those who consumed at least one serving of leafy greens per day had a cognitive decline rate that was equivalent to being 11 years younger than those who consumed no leafy greens at all.

The researchers believe that one reason for the positive effect of leafy greens on cognitive decline may be their high vitamin K content. Vitamin K is important for brain health as it helps to regulate calcium, a mineral that is critical for brain function. Other nutrients found in leafy greens, such as beta-carotene and folate, may also play a role.

Implications

The findings of this study have important implications for public health. Cognitive decline is a major public health issue, with an estimated 47 million people around the world currently living with dementia. While there is no cure for dementia, research into preventative measures such as dietary changes is growing.

This study suggests that promoting an increased intake of leafy greens could be a practical and effective way to reduce the risk of cognitive decline. It is also important to note that leafy greens are already recommended as part of a healthy diet by health authorities, due to their numerous other health benefits.

FAQs

How much leafy greens should I eat?

The study found that participants who consumed at least one serving of leafy greens per day had a lower rate of cognitive decline than those who consumed none. One serving is considered to be one cup of raw leafy greens or 1/2 cup of cooked greens. However, everyone’s dietary needs are different, so it is important to speak to a healthcare professional about the appropriate amount of leafy greens for your individual needs.

Which leafy greens are the best?

The study did not specify which types of leafy greens were most beneficial for cognitive health. However, in general, the darker the green, the more nutrient-dense the vegetable is likely to be. Spinach, kale, collard greens, and Swiss chard are all good options.

Can I get the same benefits from supplements?

The study only looked at the intake of leafy greens, not supplements. While supplements can be beneficial for some people, it is generally recommended that nutrients be obtained through a varied diet rather than supplements. Additionally, supplements may not contain all of the beneficial compounds found in whole foods. As such, it is always best to speak to a healthcare professional before taking any supplements.

What other foods can help to prevent cognitive decline?

There is growing evidence that a healthy diet overall can help to prevent cognitive decline. In addition to leafy greens, fruits, vegetables, whole grains, lean proteins, and healthy fats are all important parts of a healthy diet. In particular, foods that are high in omega-3 fatty acids, such as fatty fish, flaxseed, and walnuts, are believed to be beneficial for brain health.
