High protein, low fat, perfect for dieting
Flounder season runs from late October, when fall begins in earnest, to late January, when cold weather is in full swing. At this time, flatfish are actively feeding in preparation for the spawning season in spring, so they are fat and high in fat, so they taste better.
Flounder is a high-protein, low-fat white fish that contains almost no sugar. The fat content is 3.7 g per 100 g, about double that of flounder, and protein makes up more than 20% of the total weight. Calories are also low, 103 to 124 kcal per 100g, so even those who are very concerned about weight management can enjoy it without any weight.
Effective in the prevention of obesity and adult diseases
Flatfish is rich in essential amino acids such as valine, leucine and isoleucine, which are effective for building muscle, and ingredients that help relieve fatigue, such as citric acid. It also contains a large amount of calcium and vitamin D (18ug per 100g), so it’s excellent for growing children, preventing osteoporosis and enhancing immunity.
The lipids of the flounder are rich in omega-3, an unsaturated fatty acid, effective in the prevention of obesity and adult diseases. In particular, there are many EPAs and PAHs, which inhibit platelet aggregation and help regulate blood circulation by reducing the levels of bad cholesterol and neutral fats in the blood. It also has the effect of stabilizing blood pressure, so it is helpful in preventing hypertension and arteriosclerosis. In 2017, through its own research, the Ministry of Oceans and Fisheries discovered for the first time in the world a substance that inhibits angiotensin-converting enzyme 1 (ACE), a substance that causes blood vessels to constrict in the flatfish muscle protein.
In addition, flatfish has a powerful antioxidant called glutathione, which is very effective in removing active oxygen in the body, which is one of the main culprits in aging. It is also rich in collagen, vitamin B12 and cobalamin which is beneficial for improving skin elasticity and protecting eyesight.
