nutrition geneticsNutrition genetics is the science that explains how different compounds in food travel to the deepest cellular level, alter your DNA and trigger a response from the cell.

This can be a good response such as resveratrol  (the phyto nutrient found in red grapes)that activates the “longevity” genes inside the cell.

Or not such a great response such as refined sugar, which binds to the cell and triggers the release of irritating chemicals that cause swelling and autoimmune conditions.

Food can alter your body chemistry, e.g food rich in soluble fibre aids your body to eliminate toxins, excess hormones and cholesterol and help beneficial bacteria in the gut to grow, strengthening your immune system and reducing your risk of infections

Another example is eating a large amount of green and antioxidant foods to neutralise free radicals and keep your liver strong so it can effectively remove toxins.

The nutrients contained in the foods that we eat are subject to internal metabolic processes. Food compounds are therefore manipulated, modified, and moulded into molecules that the body can use. One of these metabolic processes is responsible for making methyl  groups, which are the epigenetic tags that silence genes.

Epigenetics consists of molecular switches such as DNA methylation in which methyl tags attach to

DNA and turn off the gene.

Histone acetylation, which makes the DNA more accessible and leads to more transcription factors being able to reach and read the DNA. The expression of your genes is modifiable. The way you can change their expressions by changing the chemical environment that your genes bathe in.

In other words DNA methylation silences genes

Histone acetylation activates genes

One cause of faulty methylation is damage caused by free radicals or oxidants molecules that are being constantly created in our bodies as well as being generated in the environment by sources such as toxins,  fried foods, poor diet, smoking and pollution.
