🌱 Aging Process and Cellular Changes

The paragraph discusses the inevitability of aging from the moment of birth, influenced by environmental factors, diet, and internal and external stresses. It explains that aging is a complex process that scientists are beginning to understand at the cellular and molecular levels. The immune system's shift from dealing with acute issues to chronic inflammation, and the shortening of telomeres are highlighted as key factors contributing to the aging process. These changes lead to a decreased ability to handle stress, potentially causing health decline when damage reaches a critical level. The paragraph also mentions the early onset of aging effects, such as hearing loss in teenagers, cognitive decline post-peak, bone strength reduction, fertility decline, and the onset of presbyopia and graying hair. It emphasizes that while aging is the primary risk factor for many chronic diseases, maintaining health through lifestyle and diet can mitigate these risks. The importance of physical activity and a balanced diet is underscored, along with the emerging understanding of how certain nutrients can promote healthy aging.

Keywords

💡Aging

Aging refers to the natural biological process of gradual decline in bodily functions over time. In the video, aging is presented as a complex process influenced by various factors including environmental exposure, diet, and stress. It's highlighted as the primary risk factor for most adult diseases, emphasizing the importance of understanding and managing the aging process to maintain health.

Transcripts

From the minute we're born, we're aging.

Constant exposure to our environment, the things we eat, and stresses from both inside

and outside our bodies all cause us to age over time.

Aging is highly complex, but scientists are starting to understand what happens at the

cellular and molecular levels.

For example, healthy cells are damaged over time when our immune systems shift from reacting

to short-term problems like injuries and infections, to gradually producing chronic inflammation

throughout the body.

Time also gradually shortens the telomeres that act as protective caps for our DNA-containing

chromosomes.

These and other changes make our bodies less and less able to deal with stress from inside

and outside of our body, so when damage reaches a critical level, our cells, tissues, and

organs may no longer perform normally and our health starts to decline.

The changes associated with aging start to happen on some level at day one.

We begin to experience their effects early in life.

For example, we lose the ability to hear certain high-frequency sounds as teenagers, our cognition

and memory slowly decline after they peak in our mid-20s, the strength of our bones

starts to decrease in our 30s, female fertility sharply declines after 35, age-related near-sightedness

begins in our mid-40s, and our hair starts to gray and thin as early as our 30s and 40s.

After the age of 50, the changes of aging become increasingly noticeable, and because

aging is the biggest risk factor for most of the diseases that affect us as adults,

the older we get, the higher our risk of chronic disease becomes.

While scientists have not yet found a way to stop these processes of aging, they are

learning more and more about how to maintain health throughout our lives.

Some aspects of aging are out of our control--like our genetics and our family history--but we

can educate ourselves about moderate risk factors and do our best to reduce them through

healthy lifestyle and diet choices.

Most of us can be healthy and active well into our later years, if we take care of ourselves.

It's no surprise that regular physical activity can help maintain a healthy weight, improve

moods and sleep habits, and boost overall health.

And it's clear that a well-balanced diet full or nutritious foods, is critical to good health.

But when it comes to understanding which foods are the best choices, much nutrition research

has focused on how certain foods or nutrients may have a negative effect on health, or even

play a role in disease development.

More recently, scientists have begun to explore and understand how nutrition may play a role

in promoting healthy aging throughout of all life's stages.

We are rapidly learning about what foods and nutrients should be emphasized in our diets,

and how they can enhance our health.

Diets full of fruits and veggies, whole grains, legumes, nuts, and lean meats, have proven

health benefits like lowering blood pressure, improving glucose control in diabetes, weight

loss, improving arthritis, and reducing the risk of cancer and cardiovascular events,

to name a few.

And we are learning more about the specific nutrients that can impact health.

For example, plant pigments found in bright orange and red fruits and vegetables may prevent

and slow the progression of eye diseases.

Calcium helps to keep bones strong.

B vitamins play a role in maintaining brain health.

And flavanoids from many plants may improve the health of our cardiovascular systems.

The bottom line is that YOU have the power to maintain and improve your health, add vitality

to your years, and reduce your risk of disease.

And it's never too late to make a change.

To learn more about the nutrients that are critical to your health, and how to safely

turn to supplements if you aren't getting enough of these nutrients in your diet, watch
