Nutrigenomics and Age Related Diseases
The article examines the role that nutrigenomics could play in helping to prevent age-related illnesses. In my role as a nutritionist and dietician, I'll provide insights on this fascinating field of research and the potential use it could have in fighting aging and associated health problems. Expect to hear about nutrigenomics' importance, how to integrate it into your life, as well as real-life case studies and tips to achieve optimal results.
Nutrigenomics and Age Related Diseases: The importance of Nutrigenomics
The study of nutrition in relation to genes is essential for understanding the nutritional requirements that are unique to each person. This is especially important in the prevention and treatment of age-related illnesses such as diabetes, heart disease, cancer and neurological disorders.
With a longer lifespan, age-related illnesses are becoming more prevalent. A study in the Journal of Gerontology found that genetics only account for about 25% of a person's lifespan. Environment and lifestyle, such as diet, determine the remaining 75% .
Nutrigenomics is a personal approach to nutrition that takes into account a person's genetic make-up. The personalized approach is promising in delaying or preventing age-related illnesses. A study published in Genes & Nutrition showed that a dietary intervention based upon nutrigenetics can reduce the risk for type 2 diabetes.
Get Started with Nutrigenomic approach
You can get your genome sequenced if you want to use nutrigenomics as a way of preventing diseases associated with aging. You can do this through companies who offer genetic tests directly to consumers. Interpreting genetic data, however, requires expert guidance. You should seek the advice of a medical professional or genetic counselor.
You can make dietary adjustments based on your genetic information once you have a better understanding of it. While nutrigenomics can provide insight on how your body will react to specific foods, this information does not replace a healthy diet that is rich in vegetables, fruits, proteins and whole grains.
Nutrigenomic interventions: Examples
- Folate. Individuals who have a variation of the MTHFR genes may require more folate. This can be obtained by eating a diet high in legumes, leafy greens and fortified grains.
- Saturated fat: People with the gene variant APOA2 are more likely gain weight when they consume large amounts of saturated fatty acids. A diet that is low in saturated fats could be beneficial to them.
- Sodium: Those who have certain variations of the ACE genes may be more susceptible to sodium and increase their risk for hypertension. These individuals can benefit from reducing their sodium intake.
- Caffeine. People who have a certain variant of the CYP1A2 genes may be able to process caffeine more slowly, which increases their heart disease risk. This risk can be mitigated by limiting caffeine intake.
- Alcohol: Some variants of ALDH2 can increase the likelihood of cancer by making it harder to digest alcohol. Alcohol consumption can also be reduced or avoided.
- Vit D. People who have variations of the VDR gene might need more than other people. Vitamin D supplements or foods rich in vitamin-D can help meet this requirement.
Useful Tips on Nutrigenomics
Maintaining a healthy life style is equally important as implementing personalized diet changes. In order to prevent disease, regular physical activity, adequate sleep and stress management are all important. It's also important to keep in mind that, although nutrigenomics may guide us toward optimal nutrition, this doesn't mean we're immune from age-related illnesses. Smoking, drinking alcohol, and exposure to the environment can also have a significant impact on our health.
Conclusion
Nutrigenomics has the potential to inform us about age-related illnesses. Understanding the relationship between genes and nutrition will allow us to make personalized diet choices which may delay or even prevent these age-related diseases. The science of nutrigenetics is evolving but the future looks promising and could change our view on health and long-term longevity.
