Frozen cephalopods (such as squid, octopus, and cuttlefish) retain their natural nutrients well after low-temperature freezing, making them high-protein, low-fat, high-quality marine foods. They are rich in taurine, DHA, selenium, vitamin B12, and other nutrients beneficial to the human body.
These foods not only have a tender and chewy texture but also offer clear health benefits, making them especially suitable for people concerned about cardiovascular health, brain development, and immune system enhancement.
1. High-quality protein source, low in fat and calories
100 grams of fresh squid contains 16%–18% protein, while its fat content is only about 4% of that of typical meats, and its calorie content is far lower than that of pork, beef, and lamb.
The edible portion accounts for over 80%, making it a highly cost-effective animal protein choice.
Although the essential amino acid content is less than 40%, thus not considered a "complete protein," it still has good development and consumption value.
2. High Taurine Content, Protects Heart and Eyes
Squid is a natural "treasure trove of taurine." Clinical studies have confirmed that:
Daily intake of 500mg of taurine (approximately equivalent to 560g of squid) can lower systolic blood pressure by 7.2mmHg in patients with mild hypertension;
Taurine accounts for 50% of the total free amino acids in the retina, and deficiency may lead to photoreceptor degeneration;
Animal experiments show that it can improve insulin sensitivity by activating the AMPK pathway, showing potential intervention for people with prediabetes.
