Which is More Important for Being Healthy - Your Genes or Your Lifestyle?
Have you ever wondered why some people seem to stay healthy no matter what they do, while others struggle with being sick and getting diseases even though they try to take good care of themselves? The reason has to do with both our genes and our lifestyles. But which one is more important? Let me tell you what I think!
First, let's talk about genes. Genes are like little instruction books that tell our bodies how to grow and develop. We inherit our genes from our parents - half from mom and half from dad. Our genes decide things like what color hair and eyes we have, how tall we might grow, and even traits about our personalities. But genes also play a big role in our health.
Some people inherit genes that make them more likely to develop certain diseases like cancer, diabetes, or heart problems. Other people's genes protect them and make it harder to get sick. It's kind of like being born with a super power or a weakness, just for health stuff!
My friend Johnny has genes that give him a higher risk of becoming overweight and developing heart disease as he gets older. His dad and grandpa both had heart attacks at a pretty young age. So Johnny's genes put him at a disadvantage when it comes to heart health. He needs to be extra careful about eating right and exercising.
On the other hand, my friend Aria has really good genes for avoiding diabetes. Her mom's side of the family never gets diabetes, even if they gain weight or don't exercise much. Aria's genes give her an advantage and protect her a little bit more from getting that disease.
So as you can see, the genes we inherit have a major impact on what diseases or health conditions we may face in life. Some people's genes stack the deck in their favor, while other people have to work harder from birth to stay healthy because of their genes. But genes aren't the whole story!
The other really important factor is our lifestyle - how we choose to eat, exercise, manage stress, get enough sleep, and take care of our bodies. Making healthy lifestyle choices can help overcome a genetic disadvantage in some cases. Or an unhealthy lifestyle can increase your risk of diseases, even if you have good genes.
Let me give you some examples. Remember Johnny with the heart disease risk genes? Well, Johnny's dad also had those genes, but his dad had a heart attack at age 45 because he smoked, never exercised, and ate a lot of fatty foods. Meanwhile, Johnny's uncle has the same genes, but he has stayed healthy so far into his 60s because he exercises every day, eats a healthy diet, and never smoked.
Then there's my friend Aria who has good anti-diabetes genes. But Aria's cousin who has the same exact genes still developed diabetes as a teenager. Why? Because her cousin was obese from drinking way too many sugary sodas and eating tons of candy and chips. Her unhealthy lifestyle overcame her genetic advantage.
See what I mean? Our genes don't tell the whole story. We can make lifestyle choices that either increase or decrease our risk of developing diseases we may be genetically prone to. It's like following the instruction book our genes give us, or ignoring it and doing our own thing instead.
In my opinion, while genes are really important, our lifestyle plays an even bigger role in determining our overall health. Here's why I think that:
We can't change our genes, but we can change our lifestyle. Our genes are set in stone from birth, but we have control every single day to make healthy or unhealthy choices about diet, exercise, sleep, and other habits.
Lifestyle can override genes in many cases. As we saw with Aria's cousin, an unhealthy lifestyle can cancel out genetic advantages and lead to diseases even in people with protective genes.
Lifestyle impacts every aspect of health. What we eat affects our risk of cancer, heart disease, diabetes, and other diseases. How much we exercise impacts things like obesity, heart health, bone strength, and brain function. Stress management affects our mental health, sleep quality, and vulnerability to illness. There's no part of our health that lifestyle doesn't play a role in.
We face new lifestyle choices every day. Maybe you have genes that make you more prone to cavities or gum disease. You can't change those genes. But every time you brush your teeth or eat a piece of candy, you're making a lifestyle choice that affects those genetic dispositions.
Of course, it's not always easy to make healthy lifestyle choices. Junk food can be really tempting. Exercising is hard work. And getting enough sleep is a challenge for kids with lots of
homework and activities. Our modern lifestyles also expose us to things like pollution, chemicals, and a lot of sitting still instead of moving around.
But developing healthy habits is worth it because doing so gives you the best chance at avoiding diseases and staying healthy, even if you weren't lucky enough to be born with perfect genes. You're shaping your own health destiny with the lifestyle you choose to live.
At the same time, we shouldn't take our genes for granted either. Someone with a high risk of breast cancer because of their genes will need to be extra diligent about annual screening and living a preventative lifestyle. We're all dealt a slightly different genetic hand in life, so we may need to work a little harder or a little less hard to overcome those genetic tendencies.
In the end, I believe focusing on your lifestyle is the most important thing you can do to pursue good health and a high quality of life. Your genes provide the general instruction manual. But your daily habits and choices have the power to rewrite that book through healthy living. Let's all try our best to move more, eat our fruits and veggies, get good sleep, and manage our stress. Our genes - and our future selves - will thank us for it!。
