The Health Secret of the Inuit: The Key is Omega-3 DPA!

Modern diets, often high in sugar, salt, and unhealthy fats, along with a lack of fresh fruits, vegetables, and whole grains, can lead to obesity and chronic diseases such as cardiovascular conditions and diabetes. However, did you know that there is a group of people with a unique lifestyle and dietary habits—the Inuit (Eskimos)—who challenge our conventional views on cardiovascular health?

The Health Secret of the Inuit

In the early 20th century, explorer Vilhjalmur Stefansson discovered that the Inuit people living in the freezing Arctic regions had little access to vegetables, fruits, or grains, yet they were among the highest meat consumers in the world. Surprisingly, they maintained excellent cardiovascular health, with low incidences of hypertension, high cholesterol, and other cardiovascular diseases. This sparked significant interest and curiosity among the medical and scientific communities. After decades of observation, scientists found that the Inuit’s diet primarily consisted of marine resources, particularly fish and seals, with seal consumption being particularly high. Research revealed that seal oil contains rich amounts of EPA and DHA, omega-3 polyunsaturated fatty acids, along with DPA, a fatty acid relatively lacking in fish oil. Medical and scientific communities believe that the Inuit's low risk of cardiovascular disease is due to their consumption of seal oil, which provides a complete range of omega-3 fatty acids (EPA, DHA, and DPA). This is also one of the reasons why seal oil was highly favored by early consumers in Europe and the U.S. over fish oil. DPA, another essential omega-3 fatty acid, also plays an important role in infant development, as it is found in high concentrations in breast milk.

However, the hunt for seals has become controversial due to the cruel and inhumane practices involved, leading to global concerns over animal rights and conservation. As a result, many countries, including the European Union, the U.S., and Taiwan, have legislated to ban the sale of seal products. This has made it more difficult to obtain DPA and the full benefits of omega-3 fatty acids, causing the public to turn to fish oil, though even the highest concentrations of fish oil still cannot provide the DPA that seal oil once did.

What is DPA?

DPA stands for Docosapentaenoic Acid, a 22-carbon, 5-double-bond omega-3 fatty acid. DPA can be synthesized from EPA and DHA in the omega-3 metabolic pathway, and it is also derived from omega-6 fatty acids. Studies suggest that both omega-3 and omega-6 DPA provide health benefits, with DPA being absorbed as efficiently as DHA, and more efficiently than EPA.

DPA and Brain Health: Enhancing Memory and Cognitive Function

Recent studies have shown that supplementing with DPA can enhance brain function and support long-term memory. Research also suggests that DPA helps alleviate neurodegenerative diseases, such as Alzheimer’s, by suppressing inflammation and reducing the progression of the disease. Therefore, DPA, EPA, and DHA are all crucial for brain health and preventing neurodegenerative disorders.

DPA Regulates Blood Lipids and Prevents Cardiovascular Disease

If you're a fan of fast food, fried foods, or have a high-fat diet, take note! High-fat diets are a major cause of chronic diseases like hypertension, high cholesterol, and other cardiovascular issues. Research indicates that supplementing with omega-3 or omega-6 DPA, combined with a diet high in animal fats, can lower total cholesterol and LDL (bad cholesterol) levels. This suggests that DPA helps regulate blood lipids and protect against cardiovascular disease.

DPA Helps Alleviate Depression

Depression and anxiety have become widespread mental health issues, with over 322 million people globally affected by depression. In Taiwan, over 2 million people suffer from depression. A study involving adolescents found that the higher the DPA levels in their blood, the lower their depression levels. Furthermore, in pregnant women, lower levels of DPA and DHA in their blood were associated with higher levels of postnatal depression three months after childbirth. This highlights the significant link between DPA and depression. If you want to reduce the risk of depression, consider supplementing with DPA.

The Importance of DPA for Infants

Mothers who suffer from eczema, respiratory allergies, or atopic dermatitis tend to have lower levels of DPA, DHA, and EPA in their breast milk, which can lead to a higher risk of allergies in their babies. On the other hand, mothers with higher DPA levels in their breast milk tend to have infants with higher DPA levels, and by the time they reach four years old, these children show better cognitive function, intelligence, and even bone density compared to a control group.

Innovative Technology for DPA from Algae

As we learn more about the benefits of DPA, it's becoming increasingly important to supplement with it. However, due to bans on seal oil in many countries and the low DPA content in fish oil, where can we obtain DPA? A biotechnology company from Europe has developed a groundbreaking solution by using a non-GMO, naturally occurring microalgae (Nannochloropsis) to produce algae oil with up to 20% DPA. This oil is free from marine heavy metals and pollutants, as well as concerns over fish farm antibiotics. It offers numerous advantages: 100% vegan, free from fishy odor, pure and natural, environmentally friendly, and highly safe. This algae oil helps fill the gap in the market for DPA, offering a natural and sustainable source to supplement omega-3 fatty acids and improve health.

If you're looking to boost your intake of essential fatty acids and enhance the absorption and concentration of omega-3s in your body, starting with algae oil DPA is a great way to improve your overall health!
