Farming and ranching can take a toll on physical and mental health. Add to that a busy family life, and it may feel that there is rarely enough time or energy for a brisk walk, jog, bike ride or swim. But where good health is concerned, science never sides with the couch potato.

In fact, Kansas State University’s Sharolyn Jackson notes that during moderate or vigorous activity, our bodies and brain produce hormones and neurotransmitters that improve our mood, enhance memory, increase energy levels and elevate our sense of well-being. And is even more important as we age.

Physical movement

“These are the body’s ‘feel-good’ chemicals at work,” says Jackson, K-State Research and Extension’s family and consumer science specialist in northeast Kansas. “While your muscles will feel tired after activity, you will probably feel more relaxed. You may also feel a sense of accomplishment, which gives you a boost of self-confidence. Feeling better as a result of movement can be a powerful motivator.”

Jackson notes that the most current research on brain health indicates three key interventions: increased physical activity, controlling your blood pressure and cognitive training.

“These are proven to be every bit as important as diet in preventing dementia and cognitive decline,” Jackson says.

Walk Kansas

Jackson is coordinator of the popular eight-week program, Walk Kansas, which draws more than 7,000 participants each year. That program encourages individuals to set a goal to exercise for at least 150 minutes each week, a guideline recommended by the Alzheimer’s Association for brain health.

“Physical activity provides so many health benefits,” Jackson says. “While more research is needed on how physical activity impacts the brain, we do know that it helps reduce falls and helps one remain independent. It also helps with depression, diabetes and high blood pressure. Perhaps all of these combined contribute to better brain health.”

The best physical activity, Jackson says, “is one that you will actually do.”

“Walking is great, and it is something almost everyone can do. Other activities like water exercise, rolling (for those in a wheelchair), yardwork and some team sports are also great. The main thing is to work hard enough so you can still talk and carry on a conversation, but not sing. Just find something you enjoy — and do it often.”

Diet

In addition to exercising regularly, a healthy diet can be good for the brain, Jackson says.

“Nutrition plays a key role in cognitive decline and research points to a combination of the Mediterranean eating style and the DASH (Dietary Actions to Stop Hypertension) diet to support brain health and reduce your risk of developing heart disease, diabetes and some types of cancer,” Jackson says. “The MIND diet [Mediterranean-DASH Intervention for Neurodegenerative Delay] is a hybrid of these two eating styles, and following it can slow brain aging by seven and a half years and lessen chances of developing Alzheimer's disease.”

Jackson notes that in 2022, the state’s Walk Kansas program will have a focus on lifestyle to support brain health, including regular physical activity, strong social connections and a deeper dive into the MIND diet.

For brain health, some foods that are especially beneficial, according to Jackson, include:

• leafy green vegetables — eat these every day
• other vegetables and fruit, especially berries
• whole grains
• fish — eat twice a week
• poultry
• beans
• nuts
• olive oil

Jackson suggests limiting — but not cutting out entirely — servings of red meat, sweets, cheese, butter or margarine, processed foods and fried foods.

“You can enjoy a glass of wine each day, but be mindful that the way your body handles alcohol can change as you age,” she says. Excessive drinking — eight drinks per week for women and 15 drinks per week for men — is linked to an increased risk of dementia; moderate alcohol consumption (one 5-ounce glass per day for women, two for men) does not seem to increase the risk.

“This is one area where we need to watch research, though, as recommendations may change,” she says. “And, if you don’t drink alcohol now, it is not a good idea to start drinking it for any possible brain benefits.”

Consult a doctor

Jackson recommends consulting with your physician to better understand your risks for dementia and other diseases, and for advice on physical activity and diet. “You can have no family history for a disease and still develop it,” she says. “Research shows that those who have a parent or sibling with Alzheimer’s are more likely to develop it themselves. If you have more than one first-degree relative, the risk is even higher.”

Reducing the risk of cognitive decline

Jackson shares suggestions for reducing the risk of cognitive decline as you age:

1. If you smoke, quit now. Smoking increases your risk for many health conditions, including cognitive decline.

2. Get adequate sleep. A lack of sleep contributes to memory loss and thinking ability. Try to get nine hours of sleep each night.

3. Develop and maintain strong social connections. Having these connections throughout life can support better brain health. Enjoy time with friends, volunteer, engage in hobbies and be part of your community.

4. Exercise your brain. Challenge your brain with card games, puzzles, learning a new skill — these all have brain boosting benefits.
