Nurture Or Nature Debate Involving Gene Changes
Nurture-or-nature-debate-involving-gene-changes

Genes are passed on from parent to child and are believed by many to be an important part of what decides looks and behavior, but also determines our chances of having several common illnesses, like heart disease, asthma and diabetes.  However, so do many other factors affect our chances, such as diet and lifestyle, environment, medicines, bacteria, and many others.  Thus, the Nurture Or Nature debate.  Many genetic and non-genetic factors affect our health, but scientists don’t yet know what they all are.

Or how they interact with each other, although progress is being made every day.  According to an National Institutes of Health (NIH) study, family history is often one of the strongest risk factors for common disease complexes.  A person inherits a complete set of genes from each parent, as well as a vast array of cultural and socioeconomic experiences from his or her family.

Family history is thought to be a good predictor of an individual’s disease risk because family members most closely represent the unique genomic and environmental interactions that an individual experiences.  Recent research in genetic health have shown that all of the “everyday” factors of life, like being social, physical, emotions, aging, occupation, spiritual or meditative, environmental, and mental, all play a huge role in influencing changes in gene structure or alteration, as well.

Wikipedia defines heredity as follows:

Heredity is the passing on of traits from parents to their offspring through asexual reproduction or sexual reproduction.  The offspring cells or organisms acquire the genetic information of their parents.

Basics on Cells, Genes, DNA, and Inheritance

The human body is composed of trillions of cells, which provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.  Cells also contain the body’s hereditary material and can make copies of themselves.

Every cell in the body with a nucleus has a complete set of genes.  A gene is made up of DNA, and it is basically a type of genetic instruction, according to the National Institutes of Health (NIH).  The instructions are guidelines for making protein molecules and controlling the chemical reactions of life.  Proteins are responsible for building, regulating and maintaining the human body.  An inherited trait is the transfer of these specific instructions in a gene code from parents to offspring.

Genes reside on chromosomes and are a small part of the chromosome.  If the chromosome is a whole book, then the genes are different chapters in the book.  The number of human genes can range from 20,000 to 25,000.  A genome is all the DNA contained in an organism or cell.  The human genome has three billion pairs of bases.  Each person has twenty-two pairs of chromosomes.  For each pair, one comes from the mother, and one comes from the father.  Since the genes are on each chromosome, there are copies of each gene, one paternal and one maternal.  In addition, there is one sex chromosome for each parent, for a total of forty-six chromosomes.

Parental and generational traits are inheritable and these traits are influenced by the genes present, but its not quite that simple.  Traits inherited can be very complex, and can be very difficult to predict from one generation to the next.  So, it can be very difficult, even for Geneticists, to determine heretital influence of a specific disease. Geneticists usually look at inheritable illnesses or diseases over several generations in one family tree.

The basic laws of inheritance are critical because they can reveal how a certain attribute or disorder (mutation) can be transferred from one generation to the next generation, but not necessarily.  Genes can change or mutate but it rarely occurs. While some mutations can be harmful, like cancer, most are not, and have little effect on inheritable traits.  Our bodies are capable of destroying cells with harmful mutations, but sometimes our bodies miss destroying the mutations, resulting in an out of control growth like cancer.

Genetic disorders or mutations, can happen for many reasons.  For example in cancer, according to the American Cancer Society, mutations are abnormal changes in the DNA and the building blocks, called bases, of a gene.  A gene mutation can affect the cell in many ways.  Some mutations can stop a protein from being made at all.  Others may change the protein that is made so that it no longer works the way it should or it may not even work at all.  Some mutations may cause a gene to be turned on, and make more of the protein than usual.  Some mutations don’t have a noticeable effect, but others may lead to a disease, like cancer.

Normally it takes many mutations in a cell to form cancer.  So, you can readily see how complicated and difficult the study of Genetics is.  Genetic disorders also are grouped by how they run in families.  Disorders can be dominant or recessive, depending on how they cause certain conditions and how they run in families.  Family history over several generations, along with the influences of every day life, is one of the strongest risk factors for inheriting diseases such as cancer, cardiovascular disease, diabetes, autoimmune disorders, and mental illness.

Through inheritance, according to the NIH, not only does the offspring receive a complex set of gene instruction, which help explain why family members look alike, why diseases like diabetes and cancer run in families, and, more importantly, why learning your family history and making changes in your lifestyle, can help keep you healthy.  But, you also can inherit a vast array of cultural, socioeconomic experiences instruction, and environmental influences, from past family relatives.

It is even more complicated when you consider recessive genes, as a recessive inheritable trait, you have to have two copies of genes to express the trait, but the carrier only has one copy, not two.  So, the carrier does not contain the trait.  However, recessive genes can mutate into dominate gene action, per an NIH study.  Studies like this one may help to broaden our insights into the mechanisms of dominant action of certain mutations in genes that are otherwise known for recessive inheritance.

Each individual also has variations in genes.  That is what makes each individual unique in its own way.  Most variations are harmless or even positive, providing an advantage in changing environments, as this NIH study reveals.  But, there is also evidence that some variations can cause disease or disorders.

According to the latest research in genetic health, it now appears genes are controlled by both internal and external factors, our thoughts, our attitude, our stress, our social activities, what we eat, physical activity, and mental attitude.  In addition, our exposure to microbes, unsuitable environments, environmental stressors such as alcohol dependence, toxins, and pollutants, are all instrumental in our genes switching on and off, determining what proteins are released, which determines if the result is health or disease.

One NIH study looked at the influence on gene impact and environment on brain development during childhood and adolescence.  The findings found and agreed with evidence from other fields that different brain regions may be particularly sensitive to environmental factors at specific periods during childhood and adolescence.  ScienceDirect addresses a variety of studies on environment and it’s role in influencing and how it affect the expression of genes.

The new research on genetics and good health, suggest that genes, life, and environment, in particular, plays a huge part in disease and illness risk.  The World Health Organization (WHO), found that most diseases involve many genes in complex interactions, in addition to environmental influences.  An individual may not be born with a disease but may be at high risk of acquiring it.  This is called as genetic predisposition or susceptibility.

For example, cardiovascular disease tends to manifest itself in specific ways unique to various communities.  For example, African communities tend to have strokes as a result of cardiovascular disease, while south Asians tend to have heart attacks.  Other researchers, such as a study published in the journal of Nature, reviewed by the NIH, for example, believe 70% to 90% of cancer development is a result of lifetime behavior and environmental factors.

Quoting the NIH:

We present evidence that inflammation is the link between the agents/factors that cause cancer and the agents that prevent it….in addition, cancer is a preventable disease that requires major lifestyle changes

So, where do you start first?  Start first with determining your true DNA, your heritage, and your family tree.  For most of us, celebrating where we come from is a vital part of understanding who we are.  A DNA test kit is a valuable tool that will determine your heritage and exactly how your family tree branches out.  For the absolute best DNA ancestry test kit on the market today, according to the experts, check out the “23AndMe DNA Test Kit.

Factors influencing Your Heredity and Overal Health and Well Being

Inheritable physical traits, both dominate and recessive, have a basic influence on your health and well being, per an NIH study.

Family historyover several generations have many factors in common, including their genes, environment, and lifestyle, and its influence on your health and well being.  In particular, medical history, and your proneness to specific illnesses or diseases, can be very revealing, and if certain risk factors exist, you should give serious consideration, and implement corrective action to reduce the risk.

Positive environmental influence, or changes, or new experiences, can effect genetic processes, influencing development and behavior, causing the genes to possibly alter its characteristics.  As an example of a negative influence initially, becoming a positive influence over time, are two genetically equal oak tree seeds, that are planted in two different soils and climates.  One is planted in rich, fertile soil in a warm, moist climate, and the other is planted in sandy soil and in a hot, dry climate. Both are given the identical care until established.

The one growing in the rick soil and moist climate grew twice as large as the other tree in the sandy soil and arid climate.  However, this is also occured. Generations later, that oak tree’s offspring will adapt to the less fertile soil and arid conditions, and the cells will change significantly, through beneficial mutation, causing the species to adapt and survive, and actually grow healthier and larger than earlier generations.  A 2008 study published in Nature Education found that internal and external environmental factors, like gender and temperature, influence gene expression.

Negative environmental influence, or changes, or new experiences, can effect genetic processes, again influencing development and behavior, causing genes to possibly alter its characteristics.  If one of your parents was exposed to mercury from eating too much fish, that external negative factor can alter the genetic process for generations to come, resulting in possibly harmful gene alterations and variations, and abnormal cell growth, in you, according to an NIH study.

Three of the genetic variants specifically associated with you psychologically, and, your mental well being have been isolated.  Genetic association with depression, which is called neurotcism, described by feeling of anxiety, fear, and negativity, can be transferred.  Some of these genetic variants are also associated with disorders like schizophrenia and anxiety disorders.  More recently, the emphasis in diagnosis has focused on neuroimaging and genetic research, per NIH research.

This approach is based partly on the need for a more comprehensive understanding of how biology, stress, and genetics interact to shape the symptoms of anxiety.   Another NIH study found evidence of shared genes is still based mainly on twin studies, but the shared neurobiology can be investigated directly by the investigation of emotional or cognitive bias either behaviorally or using functional brain imaging.

Microorganisms, both good and harmful, and the Nurture Or Nature interaction, have a significant impact on your health and well being.  Our body is a host for literally a 100 trillion microorganisms, and their DNA living in and on you, outnumber your own DNA by at least a hundred times. Good bacteria, or microflora, found in the human gut, can control genes in our cells, according to a 2018 study published in a Babraham Institute.  Their work shows that chemical messages from bacteria can alter chemical markers throughout the human genome.

The signal chemicals are made when bacteria digest fruits and vegetables.  By communicating in this way, the bacteria may help to fight infections and to prevent cancer.  A later 2018 Weizmann Institute of Science study also concluded that the connection between microbiome and health may be even more important than we thought.  Dr. Segal, one of the researchers in the study, said,

We cannot change our genes, but we now know that we can affect — and even reshape — the composition of the different kinds of bacteria we host in our bodies.  So the findings of our research are quite hopeful; they suggest that our microbiome could be a powerful means for improving our health.

Microorganisms use your body for their own purpose too, and it could result in a negative impact, as well.  The nearly five hundred billion microorganisms that live in your digestive system alone, can be linked to everything from obesity, to cancer, to autoimmune disease, to allergies, even to heart disease and diabetes.

A 2016 study published in Genomic Medicine reviewed by Cleveland Clinic addressed the issue of how trillions of bacteria in your body can change or effect your genes negatively. Different microbial communities can trigger inflammation, the body’s response to injury, and that inflammation can lead to changes in gene expression, causing the genes to switch on and off, and how our body’s cells react to this activation.

the abuse of antibiotics

Over prescribed and over use of Antibiotics, combined with a nutrition-lacking diet, and abusive lifestyle, can significantly effect our overall health and well being.  Any one of these external influences, or in any combination, can destroy the beneficial bacteria (microflora) in our digestive system and make you very sick.

The NIH calls it “the Antibiotic Crisis”, relating that the rapid emergence of antibiotic-resistant bacteria is occurring worldwide, endangering the efficacy of antibiotics, which have transformed medicine and saved millions of lives.  The antibiotic resistance crisis has been attributed to the overuse and misuse of these medications, not only in humans, but also in food animals, making them unsafe for consumption.
A 2009 Microbiology Review study found that accumulating evidence that antibiotics, besides their antimicrobial action, potentially have a number of undesired side effects that can, at least in some cases, promote genetic variability of bacteria.  In addition to resistant variants, antibiotics have also been shown to select mutator clones, thus stimulating evolution towards further resistance.

New treatments now being prescribed to replenish good bacteria in the gut, not only involve changing to specific high nutritional diets, but also the prescribing of prebiotics, probiotics, and eating naturally fermented foods.  Fermented foods are very effective in restoring the beneficial flora in the digestive system, for proper digestion and reduced inflammation.  Harvard Medical School study proclaimed the health and wellness benefits of naturally fermented foods in restoring microflora bacteria.

Stop Eating Foods That Are Unhealthy.  Modern-day convenience foods are nutritionally-deprived, and have a detrimental effect on your health and well being.  The majority of the available foods today for distribution and consumption, lack in proper nutrition, because of industry practices.  These modern-day practices include over-use of fast foods and processed foods by the general public.

All these unhealthy convenience foods are low in fiber, high in saturated fat and sugar, and added preservatives, dyes, and flavoring.  It also includes the use of “pre” everything–pre-frozen, precooked, pre-processed, not to mention the methods of distribution of what starts out to be fresh nutritious foods, sometimes traveling over thousands of miles in refrigerated trucks.  The importance of being fresh, as humanly possible, can’t be stressed enough, because foods can loose as much as 50 percent of nutrients if not fresh.

Americans also tend to eat more unhealthy foods and the following foods should be avoided:  unhealthy processed or refined foods, or precooked foods, high-sugar, processed meats, or high-sodium foods, fried foods, or microwavable foods.  All nutrient-dense foods should be grown certified organic also and GMO-free, per another NIH study.  One very good option here is to plant fruits, vegetables, nuts, and seeds, in your own backyard garden.

Eating Your Way to Better Genes

Recent studies, such as An NIH study, have suggested that the intestinal microbiome plays an important role in modulating risk of several chronic diseases, including inflammatory bowel disease, obesity, type 2 diabetes, cardiovascular disease, and cancer.

At the same time, it is now understood that diet plays a significant role in shaping the microbiome, with experiments showing that dietary alterations can induce large, temporary microbial shifts within a 24 hour period.  Given this association, there may be significant therapeutic utility in altering microbial composition through diet.  Dieticians can recommend certain type foods for certain conditions altering the behavior of the gut microflora.

One study published in the New England Journal of Medicine, and reviewed by Harvard Medical School, found that patients, after studying their family history, with a genetic predisposition to heart disease could cut their risk in half by adopting good diet and exercise habits.   The cause of cancer, for example, is a complex interplay mechanism of genetic and environmental factors, according to a study in the Journal of Microscopy and Ultrastructure.

Dietary intake of nutrient-dense foods is an essential environmental factor and there is a marked variation in cancer development with the same dietary intake between individuals due to gene variants.  There is much evidence to support genetic factors play a key role in the development of cancer; these genetic factors such as DNA instability and gene alterations are affected by nutrition.  Another Norwegian University of Science and Technology (NTNU) study found that for gene health and to limit your risk of most lifestyle-related diseases, requires a balance of one-third protein, one-third fat and one-third carbohydrates.

The average Western diet has 65 percent carbs which causes genes to work overtime, effecting genes that cause inflammation, and also genes associated with development of cardiovascular disease, some cancers, dementia, and type 2 diabetes, all the major lifestyle-related diseases.
