Of course we can’t change our birth dates, but we do have control over many aspects of the aging process. That’s the premise behind the book “Younger Next Year,” by Chris Crowley, and what health providers mean when they talk about heart “age,” mental “age” and biological “age.”
And guess what can improve the resilience and longevity of your heart, your brain, even your chromosomes? Diet!
In other words, by making simple changes in just one area of your life, you can reap benefits in many of your body’s systems. Here’s a closer look at how diet can have that impact:
Research has shown that the length of telomeres, the structures at the ends of chromosomes, influences longevity. Shorter telomeres are linked to disease and shorter lifespan. But research also shows that we can prevent shortening of our telomeres by making smart lifestyle choices. Both exercise and diet are at the top of that list.
Telomeres love a whole food, plant-based diet. Researchers suspect that’s because fruits and vegetables supply the fiber and vitamins needed to support telomere integrity. Eating less saturated fat, a natural outcome when you’re eating a whole food, plant-based diet, may also be helpful: One review shows that replacing even a fraction of the calories we get from saturated fat with something else improves telomere length, though it’s not crystal clear whether it’s less saturated fat itself or other properties of these foods that should be credited.
Had your strawberry banana smoothie today? Drink up: Eating lots of berries may be worth 2.5 years in brain health. The Harvard Nurses’ Health Study, which examined the cognitive function and diet of more than 16,000 women over 70 years of age, found this remarkable link between berries and slowing of cognitive decline.
Researchers attribute the phenomenon to something called anthocyanidins. These super nutrients have powerful antioxidant and anti-inflammatory properties and can even cross the blood-brain barrier and get inside brain regions involved with learning and memory.
But you can only reap these benefits when you eat whole real berries. Berry-flavored “fruit bits”, a common ingredient in many packaged products, just won’t cut it. Which is why at Step One Foods we use only real, whole berries. In fact, anyone who visits our offices when we’re making the smoothie mix can attest that the entire building smells like a strawberry field.
As a country, our hearts are aging faster than they should be: the hearts of American men outpace their chronological age by eight years, and the hearts of American women outpace their age by five years.
Some of the factors that contribute to an “older” heart are beyond our control, such as birth date and gender. But some -- such as cholesterol, blood pressure, blood sugar, and, for many people, weight -- can be controlled through diet. Especially a diet that supplies plenty of whole food fiber, healthy omega-3 fatty acids, antioxidants and plant sterols.
It’s no surprise, then, that people who live in communities where living to 100 is the norm eat plant-based diets that naturally deliver those nutrients. They also, by default, consume very little meat and much less dairy than most Americans consume.
HOW TO DO IT:
Don’t worry: You don’t have to grow your own kale or spend hours in the kitchen to reap these longevity benefits. Make your resolution do-able: Commit to making one small change next month. That could mean implementing Meatless Monday, cooking at home more often, or swapping out a couple of your daily snacks for Step One Foods.
