Final answer:
The people in the tribal village who consume a diet high in omega-3 fatty acids from fish are likely to experience delayed blood clotting due to the beneficial effects of these fatty acids on cardiovascular health.
Step-by-step explanation:
The staple food of the population of a tribal village is fish, which is high in omega-3 (ω-3) fatty acids. The intake of omega-3 fatty acids, such as those found in fish like salmon, tuna, and herring, tends to have beneficial effects on blood lipid profiles and overall heart health. Given the options provided, the correct answer is that these people tend to have b. delayed blood clotting.
Omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are known to lower blood triglycerides and blood pressure, reduce inflammation, and inhibit blood clot formation, which are all factors that contribute to a reduced risk of cardiovascular diseases. Conversely, diets rich in omega-6 fatty acids may contribute to increased blood pressure, blood clotting, and inflammation. Therefore, the tribal villagers' fish-based diet likely provides substantial health benefits regarding their cardiovascular system.
