What can be done to improve dietary strategies against early cognitive decline using nutrigenomic information?
We are pleased to welcome you to this discussion about the intersection between nutrition, genomics and cognitive health. In my role as a nutritionist and dietician, I'm excited to learn how cutting-edge findings in nutrigenomic research can be used to inform diets to fight early signs of dementia. You will learn about the importance of the topic and how you can implement the strategies into your everyday life. Also, there are examples of foods which support cognitive health as well as additional tips on enhancing the cognitive vitality of diet.
Nutrigenomics is important in combating cognitive decline
The field of nutrigenomics studies the interactions between genes and food. This is important in the fight against cognitive degeneration because it helps us understand that different people may respond to the same food differently depending on their genetic makeup.
Certain genetic variations can influence the absorption and metabolism of nutrients. This can have a negative impact on brain health. A study in the American Journal of Clinical Nutrition showed that people with a variant of the APOE, the gene associated with Alzheimer's, could benefit from a high-omega-3 fatty acid diet to avoid cognitive decline.
Nutrigenomics: A Start-Up for Brain Health
For a start, I suggest getting a DNA test done to determine your genetic profile. You can then work with your healthcare provider to customize your diet based on your genetic profile.
While genetics are important, other lifestyle factors, such as sleep, diet and exercise, also play an essential role. Don't neglect a healthy and balanced lifestyle as you customize your diet according to your genetics.
Nutrigenomic Strategies to Improve Cognitive Health
- Berries are rich in flavonoids and antioxidants, and can reduce inflammation, and thus oxidative stresses, both of which have been linked with cognitive decline. According to a study published in Annals of Neurology, women who ate at least 2 servings of blueberries and strawberries each week showed fewer cognitive declines.
- Omega-3-fatty acid rich fish has been shown to promote brain health. This nutrient was highlighted in the APOE gene variation study that we mentioned earlier.
- Green tea: Contains bioactive substances like EGCG, which can pass through the blood brain barrier to have a protective effect on the mind.
- Dark chocolate: It contains flavonols and caffeine as well as antioxidants. It has been shown to improve brain functions.
- Turmeric - Its curcumin active compound has shown anti-inflammatory, antioxidant and blood-brain-barrier benefits.
- Broccoli : Contains antioxidants, vitamin K and is believed to promote brain health.
- Pumpkin Seeds: Rich in antioxidants, magnesium, iron and zinc.
- Vitamin C is essential for mental health.
- Eggs are a good source of folate and choline, as well as vitamins B6 & B12.
- Walnuts are high in DHA (a type Omega-3 fatty acids).
Other Tips to Enhance Cognitive Health
You can also adopt other strategies to improve cognitive health, besides tailoring your diet according to nutrigenomic research. For a healthy mind, regular physical activity, adequate sleep and stress-management techniques like yoga and mediation are essential. Research has proven that staying socially active and mentally engaged can also help to preserve your cognitive function.
Conclusion
In conclusion, the nutrigenomic results can be used to enhance diet strategies that combat cognitive decline in its early stages. Understanding your individual genetics and adjusting your diet to meet your needs can help you optimize brain health. It's important to remember that it is not only about your genetic makeup, but about living a healthy lifestyle. Continue to learn, continue moving and nourish your body by eating the right food!
