Switching To Plant-Based Diet Can Increase Your Lifespan

 Plant-Based Diet

Can eating a plant-based diet help you live longer? A new study found that eating more legumes, grains, and nuts, and less meat can increase life expectancy by more than 10 years.

  • Researchers say people of any age can add years to their life expectancy by switching from a typical Western diet to a more plant-based regimen.
  • They say young adults can add more than a decade to their expected lifespan with this change in eating habits.
  • They add that it’s never too early or too late to make a change in your daily dietary patterns.
  • Experts say you can make the switch by eating foods with lots of color, substituting animal protein to plant protein, and choosing unsaturated oils.

You could live more than a decade longer by eating more plant-based foods.

That’s according to a new study from the University of Bergen in Norway that was published today in PLOS Medicine.

Researchers used existing data from previous analyses and the Global Burden of Disease study to create a model that estimates the effect on life expectancy from a range of dietary changes.

The model is available online and is called the Food4HealthyLife calculator.

“Understanding the relative health potential of different food groups could enable people to make feasible and significant health gains,” the study authors wrote. “The Food4HealthyLife calculator could be a useful tool for clinicians, policy makers, and laypeople to understand the health impact of dietary choices.”


Their key findings:

  • Eating more legumes, whole grains, and nuts, and eating less red meat and less processed meat, increases life expectancy.
  • The greatest increase to lifespan was seen in the 20-something age group. Males saw an average increase of 13 years and females almost 11 years.
  • People in their 60s saw an increase of an average of 8 additional years by making the switch from a modern Western diet to the more-plant based diet.


What experts say

The findings are no surprise to nutrition experts like Kristin Kirkpatrick, MS, RDN, a nutritionist and the author of “Skinny Liver,” and Dr. Danine Fruge, ABFP, the medical director at the Pritikin Longevity Center.


“It has been widely accepted that nutrition has a significant impact on our health at all ages,” Fruge told Healthline. “Our dietary habits can have a dramatic effect on whether we develop disease, reverse disease, and our longevity. Even Hippocrates noted, ‘Let food be our medicine, let medicine be our food.’”


Kirkpatrick adds the results of this study reflect previous data showing that more plants and less processed meats can decrease mortality.

For example, a 2020 analysis


published in Critical Reviews in Food Science and Nutrition demonstrated that a high intake of whole grains, vegetables, fruits, nuts, and also coffee is associated with a reduced risk for all-cause mortality. A high intake of red or processed meats was associated with higher all-cause mortality.


It’s never too late or too early

Experts encourage making changes at any age.

Fruge explains that in modern culture, as people age, they often feel that they deserve the opportunity to let down their guard and eat anything they want.


“To better enjoy their golden years, evidence suggests the contrary,” she said. “It is more important than ever to supply our aging body the nutrition it needs to enjoy our best health.”

On the flip side, Fruge adds, it’s also often challenging for young people to appreciate the importance of nutrition since they have a great resilience after poor dietary habits.

There are some telltale signs it’s time to make a change, though.


Signs it’s time to for a dietary change

Fruge says brain fog, difficulty concentrating, or an afternoon low that impacts your performance can signal that it’s time for a change.


“A simple telltale tip I use to engage young people is to ask them how they feel on an average day,” she said. “For example, do you need coffee, sugar, or energy drinks to become functional in the morning, or by noon, or to continue through your afternoon?”

Fruge says that many people, especially younger people, enjoy using technology to track health improvements and organize health data.


For example, the healthy food for life calculator used in the study, as well as mindful awareness tools and wearable trackers with alarms as reminders, can be useful and entertaining ways to make important dietary changes.


“It is never too early and never too late for anyone who is motivated to make simple nutritional changes that have powerful and often life-changing effects on both long and short term health,” Fruge said.


Tips for switching diets

Kirkpatrick offers a number of tips to help people switch from a traditional Western diet to a more plant-based approach.

Here are some of them:


Eat real food

Kirkpatrick’s advice is to focus on eating food that she says is defined by Michael Pollan as something that comes from nature, is fed from nature, and eventually rots at least 85 percent of the time.

“So eat more food, and of that food, make a lot of those choices derived from plants,” Kirkpatrick said to Healthline.


Swap animal for plant protein

Kirkpatrick also suggests starting to transition from animal proteins (meat) to plants.

For example, having a chickpea burger instead of a cheeseburger.


“You can even go with more fatty wild fish (such as salmon) as well,” she said. “Though not a plant, the benefits of omega-3 fatty acids can be obtained in certain fish.”

Kirkpatrick adds that food color reflects nutrient density, so aiming for at least five colors every day can help to achieve a diet that’s more focused on fruits, vegetables, legumes, nuts, and seeds.

 


Choose unsaturated oils

Kirkpatrick also recommends unsaturated oils.

Unsaturated oils can fall into one of two categories:

monounsaturated and polyunsaturated (TS).


says both kinds of unsaturated fats can help improve your blood cholesterol when used in place of saturated and trans fats.


The organization also notes that liquid vegetable oils, like soybean, corn, safflower, canola, olive, and sunflower, contain unsaturated fats.

“I love extra virgin olive oil for its many benefits and culinary usage,” said Kirkpatrick.
