The study of the effect of food and nutrients on gene expression is called nutrigenomics.
The above studies were started because of the impact of nutrients as well as lifestyle on health and diseases.
Adaptation to the environmental change’s nutrients intake, infections, exposure to metals, light and ionizing radiations has been essential for human survival and evolution.
Nutrition and exercise can determine which genetically susceptible individual will be affected by specific diseases and which would not. Genes, age, sex, developmental socio-economic status, occupation, education, time, geography and climate, will all establish a person unique characteristic. Genetic variation is due to variants at a single locus, which forms the basis of human diversity and the ability to handle environmental challenges.
As nutrients and physical activity influence gene expression, an appropriate diet and exercise can influence also the outcome of certain diseases.
For example, hypertension, coronary heart diseases and type II diabetes (Syndrome X), have been all recognized as diseases of insulin, and all three of them have been shown to respond positively to an appropriate and specific exercise and dietary changes. Again, the right balance of fat and the quality of fat can have a major impact on cardiovascular health. Carbohydrates containing foods and soluble and insoluble fiber are needed for energy and healthy bowel function.
A low or high intake of carbohydrates, trigger a natural change in gene expression. For example, in the presence of high carbohydrate intake, the glucose is stored by the glycogen synthesis in order to eliminate the extra glucose from the cell. When the intake of carbohydrate is constantly high, the excess glucose is synthesized into fatty acids and triglycerides, which can raise blood cholesterol.
On the other hand, when there is a low carbohydrate intake, glycogenolysis occurs to release glucose according to the body’s needs. This process is regulated by the hormone’s glucagon and adrenaline.
Also, high fiber intake has been shown in some studies to be inversely associated with advanced adenoma recurrence.
Micronutrients are quite often underestimated for the cause and trigger of certain diseases. Two thousand million people in the world are anaemic and one thousand million are at risk of iodine deficiency, 40 million children in the third country and around the rest of world suffer of vitamin A deficiency.
Deficiency of nutrients can trigger and or lead to many current diseases. Exercise also has been recognized as one factor that can help with some of modern diseases, for example an appropriate and specific regime of physical exercise can reduce the risk of developing type II diabetes in susceptible people.
This can be as simple as a 30 minutes walk in the park a day.
Therefore, many diseases can be prevented or reversed if appropriate diet, exercise and lifestyle is implemented and the knowledge of how to achieve that is one of the major goals for professional healthcare as well as the government.
Nutrigenomics also involves the studies on nutritional factors that act protecting the genome (your DNA).
My nutritional therapy consultation include your own individual need and deals with possible beliefs and trauma that have been set since childhood, dealt with craniosacral therapy on the follow ups, NLP or Mindfulness eating and meditation to support your own continuous healing at your own pace and home. It takes time to implement changes up to 6 months or more, this depends on your own commitment to your own healing!
