Healthy habits can lengthen life

At a glance.

Researchers found that people who maintained five healthy lifestyle factors lived more than a decade longer than those who didn’t maintain any of the five.
The results suggest that Americans can increase the length of their lives and lower their disease risk by adopting a healthier lifestyle.

American don’t live as long as people in most other high-income countries. Heart disease and cancer are two of the most common preventable chronic diseases in the United States. An unhealthy lifestyle increases your risk for these and other chronic diseases that can lead to an early death.

To explore the effects of healthy habits on Americans’ health and lifespan, a team of scientists led by Frank Hu at the Harvard T.H. Chan School of Public Health analyzed data from more than 78,000 women and 44,000 men who participated in two nationwide surveys: the Nurses’ Health Study (NHS) and the Health Professionals Follow-up Study (HPFS). They used other data from the Centers for Disease Control and Prevention to estimate the distribution of lifestyle choices and death rates across the U.S. population. The research was supported in part by NIH’s National Heart Lung and Blood Institute (NHLBI) and National Cancer Institute (NCI). Results were published online in Circulation on April 30, 2018 .

The team collected data on five different low-risk lifestyle factors and compared health outcomes for those who adopted all five with those who didn’t adopt any. The five factors included maintaining a healthy eating pattern (getting the daily recommended amounts of vegetables, fruit, nuts, whole grains, polyunsaturated fatty acids, and omega-3 fatty acids and limiting red and processed meats, beverages with added sugar, trans fat, and sodium); not smoking; getting at least 3.5 hours of moderate to vigorous physical activity each week; drinking only moderate amounts of alcohol (one drink or less per day for women or two drinks or less per day for men); and maintaining a normal weight (body mass index between 18.5 and 24.9). The researchers also collected information about the participants’ medical history, such as heart disease, cancer, and diabetes, as well as when they died.

At age 50, women who didn’t adopt any of the five healthy habits were estimated to live on average until they were 79 years old and men until they were 75.5 years. In contrast, women who adopted all five healthy lifestyle habits lived 93.1 years and men lived 87.6 years.

Independently, each of the five healthy lifestyle factors significantly lowered the risk of total death, death from cancer, and death from heart disease.

“This study underscores the importance of following healthy lifestyle habits for improving longevity in the U.S. population,” Hu says. “However, adherence to healthy lifestyle habits is very low. Therefore, public policies should put more emphasis on creating healthy food, built, and social environments to support and promote healthy diet and lifestyles.”

Bahasa Indonesia

An elderly woman shops for fruit in a supermarket.

Everyone wants to live longer. And we’re often told that the key to doing this is making healthier lifestyle choices, such as exercising, avoiding smoking and not drinking too much alcohol. Studies have also shown that diet can increase lifespan .

A new study has found that eating healthier could extend lifespan by six to seven years in middle-aged age adults, and in young adults, could increase lifespan by about ten years.

The researchers brought together data from many studies that looked at diet and longevity, alongside data from the Global Burden of Disease study, which provides a summary of population health from many countries. Combining this data, the authors were then able to estimate how life expectancy varied with continuous changes in intake of fruit, vegetables, whole grains, refined grains, nuts, legumes, fish, eggs, dairy, red meat, processed meat and sugary drinks.

The authors were then able to produce an optimal diet for longevity, which they then compared with the typical western diet – which mostly contains high amounts of processed foods, red meat, high-fat dairy products, high-sugar foods, pre-packed foods and low fruit and vegetable intake. According to their research, an optimal diet included more legumes (beans, peas and lentils), whole grains (oats, barley and brown rice) and nuts, and less red and processed meat.

The researchers found that eating an optimal diet from age 20 would increase life expectancy by more than a decade for women and men from the US, China and Europe. They also found that changing from a western diet to the optimal diet at age 60 would increase life expectancy by eight years. For 80-year-olds, life expectancy could increase by almost three and a half years.

But given it isn’t always possible for people to completely change their diet, the researchers also calculated what would happen if people changed from a western diet to a diet that was halfway between the optimal diet and the typical western diet. They found that even this kind of diet – which they called a “feasibility approach diet” – could still increase life expectancy for 20-year-olds by just over six years for women and just over seven years for men.

A table which shows how many grams of each food group a person should aim to consume on each of the three diets the researchers looked at in their study.

These results show us that making long-term diet changes at any age may have substantial benefits to life expectancy. But the gains are largest if these changes start early in life.

Full picture?

The life expectancy estimates this study makes come from the most thorough and recent meta-analyses (a study that combines the results of multiple scientific studies) on diet and mortality.

While meta-analyses are, in many cases, the best evidence because of the amount of data analysed, they still produce assumptions with the data, which may cause important differences between studies to be ignored. It’s also worth noting that the evidence for reducing consumption of eggs and white meat was of a lower quality than the evidence they had for whole grains, fish, processed meats and nuts.

There are also a few things the study didn’t take into account. First, to see these benefits, people needed to make changes to their diet within a ten-year period. This means it’s uncertain if people may still see benefits to their lifespan if they make changes to their diet over a longer period of time. The study also didn’t take past ill-health into account, which can affect life expectancy. This means that the benefits of diet on life expectancy only reflect an average and may be different for each person depending on a variety of other factors, such as ongoing health issues, genetics and lifestyle, such as smoking, drinking alcohol and exercise.

But the evidence the researchers looked at was still robust and drawn from many studies on this subject. These findings also align with previous research which has shown that modest but long-term improvements to diet and lifestyle can have significant health benefits – including longevity.

It’s not yet entirely clear all the mechanisms that explain why diet can improve lifespan. But the optimal diet that the researchers uncovered in this study includes many foods that are high in antioxidants. Some research in human cells suggests that these substances may slow or prevent damage to cells, which is one cause of ageing. However, research in this area is still ongoing, so it’s uncertain whether antioxidants that we consume as part of our diet will have the same effect. Many of the foods included within this study also have anti-inflammatory properties, which may also delay the onset of various diseases – and the ageing process.

Of course, changing your diet completely can be difficult. But even introducing some of the foods shown to increase longevity may still have some benefit.

Scientists Calculated How Much Longer You Can Live With a Healthy Lifestyle

healthy and filling, health food, diet, nutrition, time.com stock, asparagus

S tudy after study reminds us that as challenging as it can be, sticking with healthy habits— eating right , exercising regularly, not smoking , maintaining a healthy weight , and controlling how much alcohol you drink—can help us to live longer . But tacking on extra years isn’t so appealing if some or most of them are riddled with heart disease, diabetes or cancer.

In a 2018 study , an international group of researchers led by scientists at Harvard T.H. Chan School of Public Health found that adopting five healthy habits could extend life expectancy by 14 years for women and by 12 years for men:

eating a diet high in plants and low in fats
exercising at a moderate to vigorous level for several hours a week
maintaining a healthy body weight
not smoking
consuming no more than one alcoholic drink a day for women and two for men

To follow up on that data, the researchers wanted to know how many of those added years were healthy ones, free of three common chronic diseases: heart disease, type 2 diabetes and cancer. And in a study published Jan. 8 in BMJ , they report that a healthy lifestyle can indeed contribute to more—and more disease-free—years of life. The results suggest that women can extend their disease-free life expectancy after age 50 by about 10 years, and men can add about eight years more, than people who don’t have these habits.

“It’s important to look at disease-free life expectancy because that has important implications in terms of improving quality of life and reducing overall health care costs,” says Dr. Frank Hu, chair of the department of nutrition at Harvard T.H. Chan School of Public Health and senior author of the paper. “Extending lifespan is not sufficient, we want to extend health span, so the longer life expectancy is healthy and free of major chronic diseases and disabilities associated with those diseases.”

To figure out those patterns, the researchers analyzed data collected from more than 111,000 U.S. women and men who were between the ages of 30 and 75 when they enrolled in the Nurses Health Study or the Health Professionals Follow-Up Study beginning in 1980 and 1986, respectively. The participants answered questionnaires about their lifestyle habits and their health every two years through to 2014. Based on their answers, each participant was given a “lifestyle” score from 0-5, with higher scores representing better adherence to healthy guidelines. The researchers then attempted to correlate these scores to how long the participants lived without heart disease, cancer or diabetes.

Women who reported satisfying four or five of the healthy habits lived on average 34 more years without those diseases after age 50 compared to 24 years for women who said they did not follow any of the healthy habits. Men who reported fulfilling four or five of the lifestyle habits lived on average 31 more years free of disease after age 50 while those who adopted none of them lived on average 23 more years after age 50.

Hu says that none of the five factors stood out as more important than the others; the benefits in saving people from disease and in extending life were similar across all five. Further, the evidence suggests that the contributions of each factor are additive—the number of years of disease-free life gained increased with each additional healthy habit people followed. “People shouldn’t be discouraged from adopting them if they find one or two factors difficult to follow,” says Hu.

And because all of the participants in the study were over age 30, the findings also suggest that “it’s never too late to change,” Hu says. “It’s always better to adopt healthy lifestyle habits as early as possible, but even adopting them relatively late in life is still going to have substantial health benefits later on.”
