Why You Should Be Eating These Foods
As we age, our nutritional needs evolve, and incorporating specific foods into our diet can significantly impact longevity and overall health. Dr. David Sinclair, a leading expert on longevity, has dedicated his research to understanding the role of sirtuins—genes responsible for regulating aging. A key factor in boosting these longevity genes is Nicotinamide Adenine Dinucleotide (NAD), a crucial coenzyme in our mitochondria that converts food into energy.
By midlife, NAD levels decline by nearly 50%, which can accelerate the aging process. While supplements and injections have gained popularity in boosting NAD, the foundation of maintaining optimal levels should begin with diet. Below, we explore seven essential foods that can naturally enhance NAD production and promote longevity.
1. Beef Liver
Contrary to popular misconceptions, beef liver is one of the richest sources of niacin (Vitamin B3), a vital component in NAD production. Many sources mistakenly claim that chicken has the highest niacin content, but in reality, beef liver surpasses it significantly. Additionally, beef liver is packed with other essential B vitamins, iron, and high-quality protein, making it a powerhouse for cellular health.
2. Grass-Fed Red Meat
Grass-fed red meat is another excellent source of niacin and essential nutrients that contribute to overall well-being. It is often wrongly vilified, but when consumed in moderation, it provides a robust supply of vital amino acids and micronutrients that support energy production, muscle maintenance, and cognitive function.
3. Fermented Foods (Sauerkraut & Yogurt)
Fermented foods, particularly raw sauerkraut and high-quality yogurt, are rich in probiotics and niacin. Sauerkraut made from purple cabbage offers additional anthocyanins—potent antioxidants that support cellular health and combat inflammation. When choosing yogurt, opt for unsweetened, probiotic-rich varieties or consider making your own to ensure maximum benefits.
4. Parsley, Celery, and Chamomile Tea
These natural plant-based foods contain essential compounds that contribute to NAD production and overall health. While parsley may not be a favorite for everyone, using it as a seasoning can still provide its nutritional benefits. Celery and chamomile tea also play a role in supporting the body’s detoxification processes.
Additionally, cruciferous vegetables such as broccoli sprouts and radish sprouts are rich in sulforaphane, a compound known to boost NAD levels and aid in detoxification. Including these vegetables in salads or as side dishes can offer multiple health benefits.
5. Anthocyanin-Rich Foods (Blueberries, Blackberries, and Purple Cabbage)
Anthocyanins, found in dark-colored fruits and vegetables, help combat oxidative stress and promote mitochondrial function. Blueberries, blackberries, and purple cabbage are some of the best sources of these beneficial compounds. While grapes also contain anthocyanins, their higher sugar content makes berries a better choice for those focused on longevity.
6. Turmeric (Curcumin)
Turmeric contains curcumin, a powerful anti-inflammatory compound that also supports NAD production. The best way to incorporate curcumin into your diet is through curries, but be mindful of added sugars. Preparing homemade curries with grass-fed lamb or beef can be an excellent way to maximize curcumin intake while maintaining a nutrient-dense diet.
7. Omega-3 Fatty Acids (Wild-Caught Salmon & Cod Liver)
Omega-3 fatty acids, particularly EPA and DHA, play a crucial role in reducing inflammation and supporting brain function. Wild-caught salmon is one of the best sources of these essential fats. Another overlooked yet highly nutritious option is canned wild-caught cod liver, which not only provides omega-3s but also supplies vitamin A and vitamin D—both critical for immune and bone health.
Conclusion
Incorporating these seven foods into your diet can help boost NAD levels, support mitochondrial function, and promote longevity. While supplements may provide an additional boost, prioritizing whole, nutrient-dense foods remains the best approach to sustaining optimal health as we age.
