Harvard scientists: Red meat tied to increased dementia risk

In a 2025 Harvard study of more than 133,000 people followed for four decades, those who ate the most red meat each day (a quarter-serving or more) had a 13% higher risk of developing dementia later in life, compared with people who ate the least.

Processed red meat linked to higher risk of dementia

A 2025 study suggested that people who eat higher amounts of processed red meat may be more likely to develop dementia than people who eat very little of it.

An introvert's guide to socializing

An active social life is good medicine for the body and brain as it lowers the risk for many chronic diseases and protects against dementia and mild cognitive impairment. However, people who are introverts and enjoy their solitude can struggle with engagement. These individuals can benefit from socializing while maintaining their comfort levels by engaging in activities like joining social clubs and other groups, taking classes, and attending public events.

Can a routine vaccine prevent dementia?

It's fairly common for a medical treatment to cause side effects - but far more rarely, a side effect provides an unexpected benefit. This might be the case for the shingles vaccine, as evidence is mounting that it might also reduce the risk of dementia.

Eating too much processed red meat may increase dementia risk

Eating high amounts of processed red meat each day may increase the risk for future cognitive decline and dementia. Switching out processed red meat for nuts, legumes, low-fat dairy, chicken, or fish also may lower the risk.

The healing power of kindness

Acts of kindness do more than make the giver and recipient feel good-they can also bolster psychological and physical health. Research suggests kindness can improve happiness and increase social connectedness as well as reduce anxiety and lower blood pressure. Evidence also suggests concentrating good deeds into shorter time periods enhances well-being more powerfully than spreading actions out. Kind acts can include complimenting people, running errands for a neighbor, making a donation to charity, and signing up to volunteer.

Pay attention to concentration

Decreased concentration is often a normal part of aging as the brain's ability to function efficiently gradually declines. People who struggle with concentration when performing tasks can try strategies like avoiding multitasking, taking scheduled breaks, and removing distractions. Other lifestyle behaviors may also affect concentration and should be examined, such as sleep, medication, and caffeine intake. Activities like meditating, reading, and learning a new skill also can help improve mental focus.
