3 common factors may be secretly speeding up the aging process, expert says

Lifestyle habits and environmental exposures may affect processes involved in cellular health and biological aging.

That's according to functional medicine expert Dr.

Will Cole, co-author of the upcoming book "Heal Your Cells," who believes modern lifestyle factors may contribute to cellular dysfunction, which can can influence inflammation, sleep and other processes tied to overall health.

"Our genetics haven't changed in thousands of years, but our world has changed dramatically in such a finite period of time," Pennsylvania-based Cole told Fox News Digital.

"It’s the foods we're eating or not eating, it's environmental toxins that were never on the landscape before, it’s stress and trauma ."

"Many people in their 20s, 30s and 40s have the cells of a senior citizen ," he said.

"That's common, [but] not normal." Cole noted that people may normalize persistent symptoms, such as brain fog and fatigue, instead of discussing them with a health professional .

Those symptoms are non-specific and can stem from a range of medical, lifestyle and mental-health factors.

EATING COMMON DAIRY FOOD EVERY DAY MAY SLOW BIOLOGICAL AGING, STUDY SUGGESTS Cole said that, in some cases, changes tied to cellular dysfunction may begin years before a person receives a medical diagnosis — but that people often dismiss or push through early symptoms.

He identified the following three factors that can most disrupt cellular communication, creating "cellular noise" that may contribute to accelerated aging and disease.

Eating foods that "don’t love human body back" is the first agitator of cell health — particularly inflammatory foods, according to Cole.

Failing to stick to a consistent eating window — and instead eating over long stretches of the day without giving the body time to digest and fast — can also disrupt cellular balance, he said.

Cole cited certain environmental exposures, including pesticides, herbicides and PFAS — sometimes called "forever chemicals" — as potential concerns for overall health.

The effects of an exposure depend on the substance, dose and duration of contact, experts say.
