“If we’re lucky, we’ll all grow old.” – unknown
As we age, there are obvious and not-so-obvious changes that occur. Hormones shift, joints ache, and skin starts to become less vibrant and plump. Your risk for most diseases increases as you age – heart disease, diabetes, cancer.
The million-dollar question is “why?”
The ten-million-dollar question is “how do you stop it?”
This article isn’t meant to solve all your aging woes but is meant to provide some info and tools to help you encourage healthy function and longevity on a cellular level.
You’ve probably heard or seen the terms antioxidant, free radical, and maybe even oxidative stress. But what do these terms mean and more importantly – why do they matter?
What are free radicals and why do we hate them?
You may think free radicals are bad things (especially if you’ve ever seen or read a beauty product advertisement). But free radicals are just naturally occurring molecules that are created when your cells use oxygen.
Simply put, free radicals are the by-product of your cells using oxygen.
Free radicals don’t always come from within – there are external free radicals found in the environment. Examples of free radicals in the wild include:
Certain scenarios or conditions can also promote excess free radical formation. Some of these include:
As you can see, it’s hard to fully avoid external free radicals, but that’s not the point. Telling you to hide from the sun, don’t work out, and never get an infection is as realistic as telling your cells to not use oxygen.
Like everything in life, it’s all about balance. Once free radicals are created, your body uses antioxidants to remove them. Wanna know what else antioxidants are called? Free radical scavengers. Isn’t that the coolest name ever?
Antioxidants prevent and repair any damage caused by these free radical rebels to keep your cells and body healthy. If there are more free radicals running around than there are antioxidants to keep them in line, oxidative stress can occur.
Oxidative stress: the real troublemaker.
Oxidative stress happens when there is an imbalance between free radicals and antioxidants. When oxidative stress is around, it bullies and beats up your cells and can cause damage.
Damage on a cellular level carries all kinds of consequences. Damage from oxidative stress can lead to a variety of diseases including heart disease, diabetes, eye diseases like cataracts, and cancer.
Oxidative stress is thought to play a crucial role in aging as well. When skin cells become damaged or altered, common signs of aging can appear. Oxidative stress also makes it more difficult for your skin to repair from damage caused by oxidative stress.
One example is signs of sun damage. If you’ve spent a life worshiping the sun, your body eventually can’t keep up and this is when discoloration, uneven skin texture, and skin cancers can occur. Another is the natural loss of moisture in our skin as we age. Typically, collagen and antioxidant actions would replenish your dehydrated skin and plump it right up.
This is why you still looked refreshed, glowing, and rejuvenated after a night of drinking Everclear out of a Rubbermaid cooler in your 20s.
But eventually, the lack of hydration wins, and fine lines and sunken skin can set it. This is why two glasses of Merlot while you watch Bridgerton make you look like you haven’t slept in 5 days when you’re in your 30s.
Now take these examples for the skin, and apply them to every organ, tissue, and muscle in your body. An imbalance of free radicals and antioxidants causes stress in these areas, making it more difficult for cells to repair and protect themselves.
Since antioxidants scavenge and regulate free radicals and when they do this, oxidative stress is reduced, where can you find antioxidants?
I thought you’d never ask.
Where to find antioxidants.
recently watched the Netflix documentary Seaspiracy which is a real-time loss of innocence tale for an endearing whale, dolphin, and overall ocean lover.
I don’t think this is a spoiler, but an emerging theme of the film is finding plant-based solutions instead of eating fish (and mammals) from the ocean. This included the conundrum of people eating fish to get their omega-3 fatty acids. This essential fat is found in sea life like salmon, sardines, herring, and tuna.¹
But as it turns out, fish don’t organically create these helpful fatty acids known to reduce heart disease risk and lower triglycerides. So who (or what) makes omega-3 fatty acids?¹
