Frequently Asked Questions
Throughout the years, medical professionals have cautioned against excessive consumption of dairy items. They advise against cheese, milk, and encourage the intake of fish like salmon, known for its high levels of essential fatty acids associated with a longer life. The essence of the Mediterranean Diet revolves around this principle. However, there might be a shift in this perspective as scientific advancements in anti-aging have revealed a groundbreaking discovery - a novel essential fatty acid linked to enhanced longevity, a find not present in salmon or the Mediterranean Diet.
Milk has a significant impact.
This natural product contains a specific fatty acid that has only recently been identified. This fatty acid outperforms the most promising longevity drug developed by conventional medicine - more details on this shortly.
The fatty acid, known as pentadecanoic acid or C15:0, was not discovered by anti-aging researchers but rather by a veterinary epidemiologist examining bottlenose dolphins.
Indeed, bottlenose dolphins off the California coast, despite receiving similar diets and healthcare as those near Florida, were experiencing health issues that typically lead to heart disease, stroke, and diabetes in humans. The San Diego bottlenose dolphin community lacked saturated fat, specifically C15:0. Upon increasing their C15:0 intake, their health conditions stabilized, and their cellular stability improved by 72%.
Given the similarities in aging processes and age-related illnesses between dolphins and humans, could this discovery benefit us? Over thirty studies conducted over the past decade suggest a positive outcome.
The answer is a resounding yes.
An analysis of 18 studies involving over 15,000 adults and another study tracking 25,000 adults for 13 years revealed that individuals with higher C15:0 levels had a lower likelihood of developing cardiovascular ailments. Additional studies indicate a reduced risk of heart attack and heart failure.
Higher levels of C15:0 contribute to healthier fasting glucose levels and glucose tolerance, reducing the risks of diabetes and high blood pressure.
Moreover, elevated C15:0 levels are associated with decreased total cholesterol, triglycerides, and ApoB, a relatively unknown fatty protein recently recognized as "the new bad cholesterol." ApoB is now considered a vital marker for cardiovascular diseases and is elevated in metabolic syndrome.
How does C15:0 exert its effects?
Imagine C15:0 as an exceptionally proficient multitasker within your body. It resembles that one friend who excels in everything - you know the type.
Initially, C15:0 interacts with PPARs, acting like switches distributed across your brain and body. When C15:0 activates these switches, it triggers a range of health benefits. One type of switch aids in lowering blood fats (triglycerides), while another helps alleviate inflammation and regulates your sugar and fat metabolism.
C15:0 also influences an enzyme called AMPK, acting as the body's "Mr. Fix-It." AMPK diminishes inflammation, combats harmful molecules, enhances insulin utilization, improves blood circulation, and safeguards the heart. It's indeed a diligent worker!
C15:0 doesn't stop there. It also supports your mitochondria, the miniature powerhouses in your cells. When these powerhouses function optimally, your heart receives a boost as well.
In addition, C15:0 helps regulate a troublemaker known as mTOR. Overactivity of mTOR can lead to various health complications. By controlling mTOR, C15:0 aids in reducing inflammation and facilitating your cells' waste removal process (autophagy).
Studies suggest that individuals with lower C15:0 levels face higher risks of heart disease, diabetes, fatty liver disease, and certain cancers. C15:0 acts as a gatekeeper in your body, preventing unwanted bacteria and fungi from disrupting your system.
Dr. Venn-Watson, specializing in researching this fatty acid, highlights that laboratory investigations indicate that C15:0 enhances the resilience and durability of cell membranes, combating age-related deterioration.
“Besides fortifying cell membranes,” she elaborates, “C15:0 mitigates various aging indicators, including cellular senescence, inflammaging, mitochondrial dysfunction, and impaired cellular signaling.
“In peer-reviewed studies, C15:0 has been demonstrated to bolster cell membranes, restore mitochondrial function, and enhance cellular signaling (including activating PPAR alpha and delta and AMPK receptors while inhibiting mTOR) – these are established targets for reducing inflammation, regulating glucose, curbing cellular senescence, and diminishing cancer cell proliferation.”
Laboratory research unmistakably showcases the anti-aging attributes of this exceptional fatty acid. However, do these remarkable findings have real-world implications for humans?
German scientists aimed to determine whether specific lipids hasten or decelerate biological aging - the rate at which our cells and tissues age. To investigate this, they utilized two parameters that monitor epigenetic clocks in 4,151 older individuals. Their findings indicated that individuals with higher C15:0 levels exhibited slower aging in both clock measurements.
Dr. Venn-Watson, along with a fellow researcher, conducted the latest study. They compared C15:0 with three competing longevity-promoting drugs: acarbose, metformin (both used in diabetes management), and rapamycin.
For this comparison, they employed the BioMAP Diversity PLUS Panel, an industry-standard collection of human cell-based assays incorporating 12 systems mimicking disease conditions and assessing impacts on 148 biomarkers from diverse tissues. Each system was subjected to various concentrations of each compound.
The results revealed that C15:0 delivered 36 significant, dose-dependent benefits across 10 of the 12 systems, surpassing rapamycin with 32 benefits, metformin with 17 benefits, and acarbose with a mere 5 benefits. Additionally, the tests showed that this fatty acid subdued inflammation, impeded the proliferation of "zombie cells," and slowed tissue scarring in cells relevant to the heart, lungs, and liver.
In their publication in the journal Nutrients last October, the authors argue that since the body cannot produce C15:0 and it is essential for health, it meets the criteria for being an essential fatty acid - the first discovered since the omegas over 90 years ago! They propose that this fatty acid is emerging as a primary nutrient for enhancing longevity due to the discussed reasons.
And it certainly surpasses the achievements of conventional medical practices...
Rapamycin stands as the most potent conventional anti-aging medication to date. Originally found in the soil of Easter Island (Rapa Nui) in the 1960s, rapamycin, also known as sirolimus, is a compound produced by a bacterium. Presently, it is used to prevent organ rejection in kidney transplant recipients, functioning by slowing the body's immune response.
Rapamycin has garnered attention for its potential to extend lifespan and enhance health span. Studies across various organisms, including mice, demonstrate that rapamycin can delay the onset of age-related diseases and prolong life. However, suppressing the body's immune system continuously is not a desirable outcome.
C15:0 presents a significantly healthier alternative. But are you obtaining an adequate amount of it?
Dr. Venn-Watson recommends a daily intake of 100 to 200 mg to maintain blood concentrations above 5 µg/mL.
The simplest approach to achieve this is through consuming whole-fat milk, cream, yogurt, butter, and cheese. Beef and lamb also contain substantial amounts of C15:0.
Debates persist regarding the levels of C15:0 present in other foods. While the USDA database indicates minimal C15:0 content in other food items, Health Canada's esteemed food scientist, Dr. Nimal Ratnayake, notes that the fatty acid "at levels comparable to dairy fat, has also been identified in several other common dietary fats and foods, including chicken, lard, marine and freshwater fish, marine oils, certain vegetables (cabbage and cucumber), and seaweeds."
Supplements of C15:0 are also accessible.
To ensure your diet supplies adequate C15:0, request a blood test from your physician during your annual check-up. The Geneva Diagnostics Fatty Acids Nutritional Test, a specific test measuring your levels, can conveniently be included in your standard blood workup.
Recent revelations underscore the anti-aging potential of C15:0, a fatty acid present in dairy products. Initially identified in dolphins, this fatty acid fortifies cell membranes, diminishes inflammation, and promotes metabolic well-being. Research indicates that elevated C15:0 levels correlate with reduced risks of uncontrolled blood sugar, heart complications, and other age-related conditions. Unlike the conventional emphasis on fish within the Mediterranean Diet for longevity, integrating whole-fat dairy items may offer distinctive health advantages. Incorporating C15:0-rich foods or supplements may be crucial in fostering longevity and overall well-being.
