How The Food You Eat Impacts Your Genes And Why We Must Pay Attention To This.
Our progress in understanding human genes has been amazing and humbling. About 150 years ago, Gregor Mendel used pea plants to establish some rules of inheritance, and about 50 years ago, Watson and Crick described the double helix of DNA.
In 2003, the entire human genome was sequenced. Amazing! How the food you eat impacts your genes is revolutionary as it gives everyone a chance to attain true health. A person can actually reverse years of “damage done”.
What was humbling was that, when the number of genes in human cells were counted and compared to other organisms, our genome was considerably smaller than that of many other species. For example, humans have about 25,000 genes in each cell, while the tiny water flea has over 30,000!
Scientists had assumed that due to our advanced abilities and organ structure, we’d have over 100,000 genes.
While we don’t have that many genes, scientists have very recently discovered ways to control the modest number we have, in an exciting new field called epigenetics. It explains how changes in gene activity can occur without changing our actual DNA.
One way that we can influence genes without changing their basic structure is through the foods we eat. It may be that our genes load the gun, but our lifestyle pulls the trigger. The impact of nutrition on our genes is often called nutrigenomics.
Put a different way: Our fork is so powerful it can not only transport food to our mouth, it can be used as a genetic on and off switch to alter our weight, blood pressure, blood cholesterol, cancer growth, and even our chances of healthy aging.
My video defining what is Epigenetics and how food impacts your genes
1. A plant-based diet can turn off prostate cancer genes.
Dr. Ornish, a cardiologist, fed 31 men with low-grade prostate cancer a plant-based diet with fewer than 10% of calories from fat. The men were encouraged to walk, meditate and meet in group sessions. At the end of only three months, 48 genes crucial to cancer growth were found to be more active but 453 genes (ones that controlled for tumor growth and protein production) were less active in producing proteins. Overall, blood tests for prostate cancer activity improved and tumors shrunk. These epigenetic changes from the lifestyle plan were doing great things for these men.
2. A plant-based diet slows aging.
From the same group studied above, Dr. Ornish measured the activity of an enzyme produced by genes, telomerase, believed to be involved in slowing the aging process. At five years, the age-related decrease in telomerase activity was much less in the plant-based low fat group than a control group and their telomeres were longer, suggesting a slowing of the aging process. Nice!
3. A plant-based diet improves inflammation, weight, and vascular health.
A recent research group in Pennsylvania studied 63 individuals with heart disease who followed the Ornish program and compared them to a group of 63 people who did not follow any particular program. While the control group experienced no improvement in health, the Ornish group lost weight and blood pressure fell by about 10%.
At 12 weeks, researchers found that 26 genes were exhibiting different activity in the Ornish group. After a year, 143 genes were doing the same. The genes that promoted inflammation and blood vessel injury were significantly reduced in activity. The control group showed no improvements as they maintained their standard diet during the year.
When Hippocrates wrote 2,400 years ago to “let food be thy medicine,” he had no idea that scientific experiments would one day prove him a visionary. Food is no longer just a source of calories containing protein, carbs and fats. Food is information and can be viewed as a remote control to our genes, turning them on and off by a variety of modifications.
Our fork is the most powerful surgical instrument there is. Load it up with a rainbow colored, organic, plant based diet and enjoy more time to pursue our passions and dreams, free of illness and medications. Those skinny jeans are just a forkful away, you are in control.
Dr. Kahn nailed it here in this article as so many studies are showing and proving the impact good nutrition has on our overall health. This should wake you up and hopefully it causes you to start to examine what you eat on the daily basis. We have a health crisis in the US and the majority of it starts with what we put on our forks and what we drink. It’s time to get serious and improve you health!
