As early as the 1970s, researchers discovered that the low incidence of cardiovascular diseases among the Greenlandic Inuit was related to their consumption of large amounts of marine fish, which are rich in a specific type of nutrient: Omega-3 fatty acids. Subsequent studies found a significant association between Omega-3 and the incidence of cardiovascular diseases. Additionally, Omega-3 is known to promote the growth and development of the nervous system, reduce inflammation, enhance immunity, and has remarkable effects in cancer prevention.

Omega-3 fatty acids are a type of polyunsaturated fat that is essential for human health. They are important for various bodily functions, including brain health, heart health, and inflammation reduction. Omega-3 fatty acids are primarily found in fatty fish, such as salmon and mackerel, as well as in flaxseeds, chia seeds, and walnuts. There are three main types of Omega-3 fatty acids: ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid). Each type plays a crucial role in maintaining overall health.

Omega-3 consists primarily of polyunsaturated fatty acids, namely alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). The human body cannot synthesize these acids and must obtain them through dietary intake.

Dietary sources of Omega-3 fatty acids include marine fish and oil-rich plant foods, such as nuts and seeds. ALA is predominantly found in plant oils, such as flaxseed, walnuts, and other seed oils, while EPA and DHA mainly come from fish oil.

Omega-3: The Body's "Little Guardian Against Cancer"

Reducing Inflammatory Response: Chronic inflammation is a significant trigger for the development of cancer. Omega-3 fatty acids possess potent anti-inflammatory properties, alleviating the inflammatory microenvironment in the body, thereby lowering cancer risk associated with inflammation and fostering a healthier bodily environment.

Improving Gut Flora: Enhancing gut flora and increasing lactic acid bacteria in the intestines can reduce the risk of colon cancer in men.

Inhibiting Cancer Cell Growth: Omega-3 polyunsaturated fatty acids are beneficial for suppressing the growth of cancer cells and preventing their metastasis. They act as a brave "cancer-fighting guardian," capable of penetrating tumor cells and interfering with their growth signaling pathways, thus inhibiting division and spread.

Boosting Immunity: Omega-3 fatty acids can regulate the immune system and enhance the activity of immune cells, helping the body better recognize and eliminate cancer cells. They serve as a "booster" for the immune system, empowering our bodies to effectively resist cancerous invasions.

Enhancing Chemotherapy Sensitivity: The combined use of Omega-3 with anticancer drugs promotes absorption and storage of these drugs by tumor cells, increases drug concentration within tumors, and enhances the cytotoxicity of anticancer medications, thereby improving sensitivity of tumor cells to chemotherapy and enabling better treatment outcomes.

Practicing an Anti-Cancer Diet: How to Obtain Sufficient Omega-3 from Food?

Preferred Food Sources: Animal-based sources containing readily available EPA/DHA include deep-sea fatty fish such as salmon, mackerel, sardines, herring, and saury.

Consumption Suggestion: Consume 2-3 times per week, with each serving being about 100-150 grams (approximately the size of a palm).

Cooking Methods: Prefer steaming, baking, low-temperature pan-frying, or serving as sashimi. Avoid high-temperature frying to prevent oxidation and degradation of Omega-3 fatty acids.

Secondary Food Sources: Plant-based sources containing ALA require conversion; although the conversion rate is low, they remain a valuable component of a healthy diet.

Sources: Flaxseed (in powder form), chia seeds, walnuts, perilla oil, canola oil.

Dietary Recommendations: Consume one tablespoon of flaxseed powder or chia seeds daily (which can be added to yogurt or oatmeal), a small handful of walnuts, and prepare salads with perilla oil or canola oil.

When dietary intake is insufficient, supplements can be considered.

For those who do not enjoy eating fish or have dietary restrictions, high-quality fish oil or algae oil (suitable for vegetarians) is an excellent alternative.

Omega-3 fatty acids are like a "secret weapon" against cancer bestowed upon us by nature, safeguarding our health. Let’s make Omega-3 fatty acids a regular part of our diet and embrace a healthy lifestyle together!
