DNA testing is rapidly changing the way we approach our health. It provides deep insights into our genetic makeup, opening doors to understanding risks for conditions like heart disease, diabetes, and cancer, long before symptoms emerge. Research suggests that 80% of chronic diseases are preventable with the proper knowledge and lifestyle changes. What if DNA testing could provide the exact information needed to personalize your health strategies? The potential benefits are vast, from enhancing your diet to managing mental health. Keep reading to discover three ways DNA testing can improve your health.
The healthcare system faces several key limitations that affect patient care.
Here are some of the significant challenges:
DNA testing provides essential information in several areas, from health to family connections, making it a vital tool for addressing key issues today, such as:
DNA testing has evolved beyond ancestry research and is now a valuable tool for improving health.
Here are three ways DNA testing can enhance your health:
DNA testing reveals how your body processes nutrients, reacts to specific foods, and metabolizes fats, carbs, and proteins.
For example, it may show if you're predisposed to lactose intolerance, gluten sensitivity, or how you metabolize caffeine.
This information allows you to adjust your diet to meet your body's needs, leading to better digestion, energy, and overall health.
DNA tests highlight your genetic risk for conditions like heart disease, diabetes, or certain cancers.
While these results don't guarantee you'll develop these conditions, they enable you to take proactive measures.
For instance, if you're more prone to heart disease, exercising regularly, eating a heart-healthy diet, and scheduling routine check-ups can be practical steps.
DNA testing provides valuable information on genetic factors that affect mental health.
Some tests analyze genes associated with conditions like depression, anxiety, or ADHD.
Knowing your genetic predisposition helps develop a personalized mental health plan with therapy, lifestyle changes, or treatments.
Note: Always consult a doctor to interpret your DNA test results and create a personalized health plan based on your genetic profile.
DNA testing is now considered highly accurate, with reputable companies reporting reliability rates exceeding 99.9%.
Despite this accuracy, privacy remains a significant concern, as genetic data may be vulnerable to unauthorized access if not securely stored after submission.
Even with security measures like encryption, your genetic information remains vulnerable.
It could be shared without your consent with entities like research institutions or pharmaceutical companies.
Protecting your privacy can involve choosing providers with strong data privacy policies, being mindful of how your data is utilized, and minimizing data sharing.
Since genetic data cannot be changed like a password, users must carefully consider the long-term implications before undergoing DNA testing.
You can get a DNA test from several places:
The rising cost of healthcare is a big concern for people, governments, and employers.
Expensive treatments, medicines, and administrative costs make it harder to afford care and increase health inequalities.
One primary reason for these high costs is inefficiency in healthcare systems.
Many tasks, such as insurance claims, patient billing, and record management, still require manual work. This slows things down and raises expenses.
Additionally, healthcare relies on unstructured data, which makes it challenging to analyze and use information appropriately.
These inefficiencies worsen other problems, such as limited access to care, managing long-term illnesses, and meeting the needs of an aging population.
DNA testing has several downsides, including:
According to a systematic review, whole-exome sequencing (WES) costs between $555 and $5,169, while whole-genome sequencing (WGS) costs between $1,906 and $24,810.
These estimates vary based on laboratory fees, sequencing depth, data interpretation, and whether clinical consultations are included.
The review also found that many cost analyses lack transparency, making it unclear which components are covered.
While WES and WGS can potentially improve genetic diagnosis, more research is needed to evaluate their cost-effectiveness in clinical practice.
While genetic tests provide valuable insights, they do not offer a complete picture of health or future risks.
They mainly identify common genetic variations but may miss rare ones contributing to certain conditions.
Genetic testing cannot detect diseases influenced by environmental factors, infections, or random events.
These tests also cannot confirm whether someone will develop symptoms of a disorder, how severe it will be, or how it may progress.
Additionally, many genetic disorders have no effective treatment, even if identified.

In a room of 25 people, chances are, only two people are likely to be left-handers. Handedness is the preference for one hand over the other for everyday tasks like eating or writing. There are three types of handedness – Left-handedness, right-handedness, and mixed-handedness (an equal preference for either hand). Data collection studies say that about 12% of the world’s population is left-handed, and about 1% is mixed-handed. Biologically, handedness could have a link to the coordination and function of your brain's right and left hemispheres. This article will explore the genetics behind handedness and why there are so many more right-handers than left-handers.
Handedness refers to an individual’s preference to use one hand (called the dominant hand) over the other for tasks like writing, eating, cutting with scissors, etc.
Globally, more than 85% of people are right-handed.
Left-handedness is a fairly rare trait with a prevalence of under 15%.
Mixed-handedness is defined as preferring different hands for different tasks, and ambidextrousness is the ability to perform tasks equally well with either hand.
The widespread prevalence of right-handedness suggests that it could be beneficial but also begs the question of how left-handedness originated.
Typically, the left and right hemispheres of the brain handle different activities.
For example, the left hemisphere is the language center and is responsible for formulating grammar and vocabulary.
The right hemisphere is involved more with visual processing and spatial sense.
Michael Corballis, PhD, a psychologist at the University of Auckland in New Zealand and a brain hemisphere specialist, mentioned to APA - “There's an advantage to cerebral dominance because it localizes function to one hemisphere; otherwise, information has to cross back and forth across the corpus callosum, and that can sometimes cause problems."
It is suggested that during early development, small variations—due to genetics, hormones, or even random "developmental noise"—can influence how the brain organizes itself.
For some people, these variations lead to a preference for using the left hand.
Twin and family studies suggest that genetics plays a role in handedness.
They report that up to 40 genes could lead to handedness through common genetic influence.
Their effect on handedness is cumulative; no single gene decides handedness.
Each of these genes exerts a small and weak influence, but together play a big role in hand preference.
Scientists have only identified a few of these genes.
One gene of interest is NME7 (NME/NM23 Family Member 7).
This gene regulates the position of organs along the left/right axis of the body.
It likely plays a role in body symmetry and your tendency to prefer your left hand.
Left-handedness persists as a minority trait in human populations due to a combination of genetic, neurological, evolutionary, and cultural factors.
Left-handedness has links to increased risks for some health conditions.
However, the strength of evidence and validity of some findings remain dubious.
Here are some key findings from scientific studies:
Inflammatory bowel disease: Left-handers have a 2x higher risk of developing Crohn’s disease or ulcerative colitis.
Cardiovascular disorders (CVD): A 2023 study by the Medical College of Georgia reported that vascular endothelial function and heart rate variability are lower in southpaws than in right-handers. This supports the increased risk of CVD in left-handers.
Breast cancer: Postmenopausal left-handed women have a higher incidence, possibly linked to prenatal estrogen exposure.

Two right-handed parents could have a left-handed child if they are both carriers of the left-handed gene without expressing it themselves. They could pass on one allele each to their child.
Within a year, at about 10-11 months, infants develop a preference for one hand over the other. This preference stabilizes over the next year or so.
A 2019 study reported no significant difference in the IQ of left- and right-handed individuals in a population.

Are Cavities Genetic? The Root Cause
Imagine you're visiting a friend in a new city. They tell you, "My house is just a few blocks from Central Park." You may not know the exact address, but knowing Central Park's location makes your search much easier. Genetic markers are biological landmarks on the map of our DNA. Scientists know the precise location of these markers on our chromosomes. This knowledge allows them to explore the surrounding genetic neighborhoods to pinpoint specific genes associated with diseases, ancestry, or how our bodies interact with medications.
Genetic markers are specific DNA sequences with well-defined locations on chromosomes that assist in identifying variations within genes or entire genomes.
The genetic marker may constitute a gene portion or possess no known function.
The primary objective of genetic marker typing is determining which gene variations are present at specific locations on your DNA.
Some common examples of genetic markers include:
Let's go over them one by one.
Single nucleotide polymorphisms (SNPs) are variations in a single nucleotide base at a specific location in the DNA sequence.
Restriction fragment length polymorphisms (RFLPs) are variations in DNA fragment lengths caused by differences in restriction enzyme cut sites.
Variable number of tandem repeats (VNTRs) are repeating DNA sequences where the number of repeats varies among individuals.
Copy number variants (CNVs) refer to differences in the number of copies of a particular DNA segment found in different individuals.
Short Tandem Repeats (STRs) are repeating DNA sequences that exhibit variable numbers of repeats among individuals.
However, these are not the only types of markers; various other forms of genetic markers exist, and scientists are constantly discovering newer types.
An RSID (Reference SNP-cluster IDentification) is a distinctive identifier designated for single nucleotide polymorphisms (SNPs) within the dbSNP database.
Moreover, they identify short nucleotide insertions, deletions, and short tandem repeats.
Researchers and databases employ RSIDs to monitor and analyze genetic variations.
RSIDs follow the format "rs##"—for example, rs429358 links to Alzheimer’s risk.
Genetic markers influence traits by altering gene function or regulation. It’s essential to understand that most traits are polygenic; this means they are affected by multiple genes and numerous genetic markers.
A single marker rarely dictates a trait.
The combination of markers inherited from both parents creates a unique genetic profile that contributes to a trait's overall expression.
This genetic influence extends across various aspects of life, from physical traits like hair and eye color to health predispositions and wellness traits.
Genetic markers also play a crucial role in ancestry tracing and paternity testing, helping us understand our roots and biological relationships.
Hair Color: A gene called MC1R produces pigments in the body that regulate our skin, hair, and eye color. Research has identified a variant in the gene named rs1805007 linked to a higher chance of developing red hair.
Lactose Intolerance: We're born with the ability to digest lactose but lose it with time due to a variation in the gene that produces lactase, which digests lactose. While the extent of it varies, the variant changes the genes, which leads to little or no lactase enzyme production.
Body weight: We humans share the same basic genetic makeup; however, gene variations can influence individual traits, including body weight. Specific gene variants can affect metabolism, appetite regulation, and how the body stores fat, predisposing some individuals to weight gain or obesity.
Physical Performance: Genetic factors also influence endurance and other athletic abilities. Specific gene variants may contribute to greater aerobic capacity, muscle efficiency, and recovery, potentially enhancing an individual's endurance levels.
Several gene variants have links to improved physical strength and performance, including ACTN3, PPARA, and AMPD1.
These variants influence muscle fiber composition, energy metabolism, and recovery efficiency.
Genetic testing helps assess disease risks and personalize healthcare, but markers only indicate susceptibility, not certainty. Environment and lifestyle also play a significant role in health outcomes.
Cancer: While lifestyle and environmental factors play a significant role, certain genetic markers can indicate a higher susceptibility to specific cancers. For instance, BRCA1 and BRCA2 markers signal a higher risk of developing breast cancer and ovarian cancer.
Drug Response: Our bodies process medications differently; genetic markers can reveal these variations. Specific gene variants can affect how effectively our bodies metabolize certain drugs, influencing their efficacy and potential side effects.
For example, variations in the CYP2C19 gene can alter how the body processes certain antidepressants, allowing healthcare providers to tailor prescriptions for optimal treatment outcomes.
Markers are key in tracing genetic lineage and verifying biological relationships.
Ancestry Tests: Genetic markers are used to trace ancestral origins and migration patterns. Specific markers can reveal a person's ethnic background and geographic origins, connecting them to populations around the world. For instance, a marker on chromosome 15 might link someone to Indigenous American heritage, providing a deeper understanding of their ancestral roots.
Paternity Tests: Genetic markers, specifically Short Tandem Repeats (STRs), are used in paternity tests to confirm biological relationships accurately. These markers are highly variable between individuals, making them ideal for identifying parent-child relationships.
For example, DYS391 on the Y chromosome helps confirm biological parentage with high accuracy, offering clarity in questions of lineage.
Genetic markers function as essential indicators of genetic variations and can offer valuable insights into an individual's health and disease risk; however, they possess limitations.
Three categories of DNA markers exist: autosomal, paternal, and maternal.
Autosomal markers: These unique DNA sequences, scattered across the genome and not sex-specific, assess overall ancestry.
Paternal (Y-DNA) markers: Located on the Y-chromosome, fathers pass these markers down to their sons. Y-DNA markers trace paternal lineages.
Maternal (mtDNA) markers: These DNA markers, located in the mitochondria, are inherited from the mother. Mitochondrial DNA markers trace maternal lineages.
Siblings share approximately 50% of their genetic markers (inherited randomly from their parents). However, this percentage can fluctuate due to various factors. Although the genetic contribution is significant, it is essential to remember that siblings are still distinct individuals. This uniqueness arises because of the random assortment of genes during reproduction.
Yes, offspring can inherit genetic markers from their parents via Mendelian inheritance.
That’s why families often share traits like height or diabetes risk.
Genetic markers play a crucial role in diagnosing numerous diseases or assessing the risk of their development.
Diagnostic Testing: A specific genetic marker can definitively confirm a diagnosis in certain cases. For example, a particular mutation in the CFTR gene confirms cystic fibrosis.
Risk Assessment: Genetic markers commonly assess disease risk. They can indicate an elevated risk for a disease but do not guarantee that an individual will develop the condition. Environmental factors, lifestyle choices, and other genes significantly influence disease development.
Some diseases for which genetic markers are used include:

We often talk about being "well," but what does that mean? Do we just mean not being sick? Or is there something more to it than that? Many people mix up the ideas of "health" and "wellness," but they're different. Health is like your body's physical condition – are you disease-free? Wellness is a much bigger picture. It's about your overall well-being, including your physical health, mental and emotional health, social connections, and how you feel about your life. When we understand the little differences between health and wellness, we can make better choices that help us feel good in every way, not just physically. It gives us more control over how we live and how happy we are.
The World Health Organisation (WHO) defines health as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity."
This means that health is not simply the absence of illness.
Good health encompasses physical fitness, mental stability, and everyday societal interactions.
It is a holistic state that allows individuals to live a fulfilling life.
WHO defines wellness as "the optimal state of health for individuals and groups."
Wellness is the active pursuit of good health and a meaningful life.
It encompasses actions and behavior that help you reach your fullest potential.
The two elements of health are:
Wellness is an idea that focuses on a broad spectrum of different elements.
The 12 elements of wellness are:
The main difference between health and wellness is the active process of achieving health, which is the goal.
Health is your predisposition to developing certain diseases like type 1 diabetes, hypertension, or cardiovascular diseases.
Wellness is the daily choices you make, like eating a balanced and taking the time out for exercise.
While you cannot always choose health, you can actively pursue wellness.
Here is a comparison between health and wellness:
Well-being is a state of equilibrium or balance in life.
It can be affected by life changes, personal problems, family responsibilities, etc.
Some define well-being as prosperity, happiness, comfort, and good health.
However, these descriptions might not fully describe well-being.
Well-being is more of a personal description of how an individual feels.
Wellness is more intricately connected to your physical and mental health.
In general, wellness practices aim to achieve optimum health through mindful practices and choices in life.
On the other hand, well-being is more connected to your emotional state.
Someone can be extremely ill yet described to be content and happy.
Similarly, someone can be physically and mentally healthy yet not feel balance and fulfillment.
This is the difference between wellness and well-being.

Poor health implies that you are physically unwell and experiencing symptoms associated with diseases.
On the other hand, poor wellness means you don't experience any diagnosable symptoms, yet you don't feel content.
This can be due to a poor diet, stress, lack of sleep, and not feeling supported and cared for.
Over time, poor wellness can eventually lead to poor health.
Health is more focused on physical and mental wellness.
It also indicates an absence of signs and symptoms of diseases.
Well-being is not just about being physically or mentally healthy but also experiencing a general satisfaction in life.
You can not be your best healthy self yet feel completely content and safe in life.
Health is a measurable metric, and well-being is a perception.
Although health and wellness are distinct from each other, both of them go hand in hand.
A foundation of good health is essential to achieve wellness, while wellness helps you become healthier.
For instance, not suffering from any digestive issues is health.
However, to maintain this, you must eat a balanced meal full of whole foods, fiber, fresh fruits, and vegetables, which is wellness.
Health care is all about getting treated for your symptoms.
It encompasses diagnosis, medication, surgery, and rehabilitation for a disease.
Wellness care implies focusing on healthy eating, exercise, and stress management.
The health triangle represents a balance between the three aspects of health:
Health and wellness are often used interchangeably.
But they have two distinct meanings.
While health is more about whether you are free from symptoms of certain diseases, wellness incorporates certain practices that keep you healthy.
Health is mainly concerned with the optimum state of your body and mind.
Wellness involves your career goals, social health, relationships, and overall attitude toward life.
Being mindful about your wellness can, in turn, help improve your health.

7 Best Biohacks For 2025 To Transform Your Health
How Genes and Hormones Interact to Influence Your Health
In the ongoing battle for better health, the question of what truly shapes our well-being remains one of the most fascinating: is it our genes, the blueprint of life, or the lifestyle choices we make every day? The answer lies somewhere in the dynamic intersection between nature and nurture, where genetic makeup forms the foundation, but our actions and habits shape the outcomes. Imagine being able to unlock the potential of your own genetic code, all while taking charge of your lifestyle to enhance your health. But how exactly do these elements work together, and what role does each play in our overall well-being? This exploration into the complex relationship between genes, lifestyle, and environment reveals how to strike the perfect balance for a healthier, longer life.
Genes influence not only your appearance but also how your body functions, responds to diseases, and processes medications.
Some genetic variations increase the risk of inherited conditions, while others affect immunity, metabolism, and treatment effectiveness.
Identifying genetic differences helps in early disease detection and prevention.
If a person carries a gene linked to a specific illness, they can take preventive steps or undergo early screenings.
Genetic insights can guide treatment choices and predict health outcomes in cases where symptoms are already present.
Advances in genetics continue to improve disease management, offering more precise and personalized medical care.
Your behavior patterns and habits can impact both your physiological and psychological health.
Below, we explore four lifestyle elements that affect well-being.
A poor diet, often full of processed foods and unhealthy fats, can lead to obesity, cardiovascular problems, and other metabolic disorders.
In urban settings, fast food is a common culprit that contributes to these health concerns.
A healthy diet, rich in nutrients, can prevent many health issues and promote long-term well-being.
Exercise plays a significant role in both physical and mental health.
Regular physical activity helps prevent diseases, supports weight management, and boosts mood.
An active lifestyle is also linked to greater happiness, reduced stress, and improved mental clarity, enhancing emotional stability.
Vices like smoking and alcohol consumption have serious health consequences, contributing to diseases such as heart disease, cancer, and respiratory issues.
They also affect mental health, leading to anxiety and depression.
Avoiding or reducing these habits is crucial for maintaining a healthy body and mind.
The misuse of medications, including self-treatment or taking drugs without a prescription, is a common issue.
When we take medications without proper guidance, it can lead to issues like drug resistance and adverse reactions.
Responsible medication use is necessary to avoid these risks and to maintain overall health.
The condition of the environment dramatically influences overall health.
Air quality, water safety, and pollutant exposure can cause conditions like asthma, heart disease, and infections.
Contaminated water can result in waterborne diseases, and polluted air can cause respiratory problems.
Living near hazardous sites like factories or waste dumps increases the risk of long-term health issues, such as cancer.
Certain groups, including low-income communities, people of color, children, pregnant women, and older adults, are more vulnerable to these risks.
These groups are often exposed to more environmental hazards due to location and limited resources.
Climate change worsens these risks by increasing extreme weather events, rising temperatures, and poor air and water quality.
These changes can lead to heat stress, storm-related injuries, and the spread of diseases through contaminated water.

The interplay of genes, lifestyle, and the environment forms a complex network of influences on our health.
Genetics provides the foundation for determining our susceptibility to certain conditions.
Lifestyle factors, such as physical activity, eating habits, and mental health, significantly influence how these genetic traits are expressed.
Furthermore, our living environment, including air quality and available resources, shapes our health outcomes.
These three factors interact constantly, creating a dynamic influence on our overall well-being.
Identifying one factor as the most important is challenging, but lifestyle choices often substantially influence health outcomes.
While genetics set the foundation, adopting a healthy lifestyle can significantly reduce risks, even for those with genetic predispositions.
Thus, lifestyle often serves as a key modulator in managing genetic and environmental influences on health.
Even if you're genetically predisposed, lifestyle changes can significantly offset those genetic influences.
A study published in the American Heart Association reveals that individuals with a high genetic risk for heart disease can lower their chances of developing it.
According to the survey, this can be achieved by adopting seven key lifestyle habits:
The study showed that white adults who adhered to these healthy habits gained up to 20 years of heart disease-free life.
The benefit was smaller for Black adults, with a 4.5-year increase in disease-free living, but it still demonstrates the positive impact of lifestyle changes.
This difference emphasizes that we need more genetic research in diverse populations to grasp the complicated relationship between lifestyle and genetics.
Ultimately, this research shows that while genetics play a role, lifestyle choices have a powerful influence on heart health and can significantly offset genetic risks.
Aging is influenced by both genetics and lifestyle, with their roles shifting at different stages of life.
Lifestyle factors, such as eating well, avoiding tobacco, staying active, and managing stress, play a dominant role in health and longevity during the early decades of life.
These healthy habits significantly reduce the risk of chronic diseases like heart disease, diabetes, and cancer, enabling many individuals to reach a healthy old age.
Genetics becomes increasingly significant as individuals age into their eighties and beyond.
Research suggests about 25% of the variation in human lifespan is attributed to genetics, though the specific genes involved remain under study.
Specific genes like APOE, FOXO3, and CETP are linked to longer lifespans, while some variants aid DNA repair and immune health.
While lifestyle choices can promote healthy aging, genetics plays a key role in sustaining health in later life.
Longevity is strongly associated with cardiorespiratory fitness, often measured by VO2 max (maximal oxygen consumption).
This metric reflects the body's efficient oxygen delivery and utilization by the heart, lungs, and skeletal muscles.
Regular physical activity enhances the function of these organs, improving overall health and reducing the risk of diseases that can shorten life.
While exercise cannot change the genetically fixed lifespan, it can improve fitness and quality of life, leading to a more extended, healthier existence.
Obesity is closely linked to both genetic and environmental factors, and recent research in epigenetics has shown how the environment can affect gene expression.
There are different genetic causes of obesity, such as:
Epigenetics helps us understand how environmental factors can change gene expression without altering the DNA.
Factors like poor nutrition, exposure to toxins, stress, and diet can lead to these changes, increasing the risk of obesity.
For example, poor nutrition or toxin exposure during pregnancy can affect the fetus (unborn baby), making it more likely to develop obesity later in life.
Additionally, unhealthy behaviors like a poor diet and lack of exercise can cause epigenetic changes in adults.
Studies like epigenome-wide association studies (EWAS) and genome-wide association studies (GWAS) help scientists identify genetic and epigenetic factors linked to obesity.
These studies show that mutations in genes related to hunger and fat storage, along with epigenetic changes, play a significant role in obesity.
No, there isn't a single "addiction gene."
Addiction develops through a mix of genetic influences and environmental conditions.
Each person inherits a unique set of genetic variations, which means different individuals can have different genetic risks for substance use disorder (SUD).
Studies suggest that genetics account for 40-60% of a person's susceptibility to addiction.
Many genes linked to addiction have been identified through research on both human and animal models.
Rather than a single genetic cause, addiction risk arises from the interaction of many genes that affect brain function, reward pathways, and response to substances.
