General Dwight Eisenhower once said that plans are nothing, but planning is everything. This sage advice from the man who orchestrated the largest military invasion in history can apply to your life too. His point was that life happens and things change, but you always need to work toward your goal.

For many older men, this means addressing some unpleasant realities like advancing age, financial challenges, and yes, even death.

Research we're watching

Last month, Harvard Women's Health Watch talked about how high blood pressure can cause a series of tiny strokes that damage your brain, increasing your risk of dementia and cognitive changes. A study in the August 8 issue of Circulation shows that this might not be the only concern when it comes to blood pressure and your mind. Researchers in Japan found that large and frequent fluctuations in blood pressure — not just high blood pressure — was associated with an increased risk of both Alzheimer's disease and vascular dementia.

The study authors asked 1,674 dementia-free participants ages 60 and older to measure their blood pressure at home, three times every morning, for about four weeks. They followed up about five years later to see who went on to develop dementia.

Want to maintain your muscle strength as you age? A study in the July issue of The American Journal of Clinical Nutrition suggests that eating protein at breakfast, lunch, and dinner may help.

While it has been long thought that when you got your protein during the day didn't make a difference as long as your intake was sufficient, emerging research shows that this may not be the case. Researchers in this study looked at a group of 1,741 healthy older men and women in Canada and followed them for three years. They assessed the participants' strength and mobility at the outset of the study, and then tracked their diets and reassessed their strength at the end of the study period. People who ate protein at all three meals throughout the day were stronger at the beginning and the end of the study than those who mostly ate their protein only at dinner — even if they ate roughly the same amount of protein over all.

Stay ahead of foot problems by inspecting your feet regularly, keeping them flexible, and wearing the right shoes.

Feet are the unsung heroes of mobility, and it's crucial to keep them healthy. Even minor problems with your feet — such as an ingrown toenail or a small cut — can leave you sidelined. "Breaches of the skin can quickly become problems, whether it's a scrape, ulcer, or blister that gets contaminated or becomes infected," says Dr. Christopher DiGiovanni, chief of foot and ankle surgery at Harvard-affiliated Massachusetts General Hospital.

Be proactive, and care for your feet the way you'd maintain any valuable equipment you rely on for mobility. Here are seven ideas to help.

Sports, walking, and stair climbing may boost balance and keep a stumble from turning into a bad fall.

When you want to improve your balance and reduce the risk of falls, you might turn to a physical therapist for an evaluation and special exercises. But sometimes other types of physical activity can do the job. "People are surprised at how adding just a little extra activity can make a big difference with their balance," says Joy Orpin, a physical therapist at Harvard-affiliated Massachusetts General Hospital.

Balance problems

Balance impairment may be linked to changes in vision or muscle strength, joint stiffness or pain, inner ear problems, or decreased sensation due to joint surgery, ankle sprains, or neuropathy (nerve damage that causes numbness or burning, especially in the feet). Other contributors to poor balance include a sedentary lifestyle or medication side effects.

Beans, lentils, chickpeas, and other "pulses" are loaded with protein, fiber, and other nutrients.

Legumes are great sources of protein for those on a meat-free diet. Lately one branch of the legume family has been in the international spotlight. "Pulses" are legumes that are harvested for their dried seeds, such as chickpeas (garbanzo beans), lentils, and dried peas and beans. They're such an important protein source that the United Nations declared 2016 the International Year of the Pulses.

"When we as nutritionists talk about beans, most of them are pulses — kidney beans, navy beans, black beans, broad beans, lima beans, butter beans — there are quite a few," says registered dietitian Kathy ­McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital. By contrast, legumes such as soybeans, peanuts, peapods, and green beans don't count as pulses.

If you haven't been good about eating a healthy diet, take heart: A Harvard study published July 13, 2017, in The New England Journal of Medicine found that changing to one of three scientifically developed healthy eating programs was associated with longer life. The healthy diets included the Alternate Healthy Eating Index, the Alternate Mediterranean Diet, and the Dietary Approaches to Stop Hypertension (DASH) diet. Scientists looked at self-reported diet and health data from nearly 74,000 healthy men and women who significantly improved their diets and maintained them for 12 years. Scientists then looked at participants' risk of death for another 12 years. The results: people who improved their diet the most were up to 17% less likely to die, whereas those whose diets worsened the most were up to 14% more likely to die. This study strongly indicates that improving your diet, even if you start in middle age, can add years to your life — and vice versa.

As we reported in May 2016, regularly drinking coffee is associated with lower blood pressure, less weight gain with aging, and less chance of developing type 2 diabetes or dying from cardiovascular or neurological diseases. Now a pair of 16-year studies published July 10, 2017, in Annals of Internal Medicine link coffee drinking with longevity. One study analyzed the coffee consumption of more than 520,000 men and women. People who drank three or more cups of coffee per day — either caffeinated or decaffeinated — were up to 12% less likely to die during the study, compared with people who didn't drink coffee. The other study involved more than 185,000 middle-age or older coffee drinkers who were African American, Native Hawaiian, Japanese American, Latino, or white. Those who drank four or more cups per day were 18% less likely to die for any reason during the study period compared with nondrinkers. This was the first large study of coffee drinking and longevity that included a racially and ethnically diverse group of people. The findings from these studies suggest, but don't prove, that regular coffee drinking helps you live longer. The beneficial effect of coffee seemed to plateau at more than four cups per day.
