Benefits during pregnancy
In addition to heart health, omega-3 fatty acids are also essential for brain health. During pregnancy, omega-3 fatty acids support healthy fetal brain development.
Adults need 1.1 g to 1.6 grams of omega-3 each day. Pregnant women should aim for 1.4 g per day. And women who are breastfeeding should get 1.3 g per day. Rainbow trout meat is perfect for the purpose.
Rainbow trout is an excellent source of vitamin D
Vitamin D belongs to the fat-soluble vitamins and is needed for bone growth. It helps promote calcium absorption, reduces inflammation in the body, and supports neuromuscular and immune function. Since vitamin D is only found naturally in a few foods, including fish like rainbow trout, it is an excellent option for a healthy dose of vitamin D from food.
Rainbow trout is rich in potassium
Potassium is one of the most important minerals. The body balances its salt by looking at the ratio of potassium to sodium.
Adults and pregnant women should consume 4, 700 milligrams of potassium each day. Rainbow trout contains 381 mg of potassium and 47.6 milligrams of sodium. That's an 8 to 1 ratio between potassium and sodium!
A potassium-rich diet not only helps manage high blood pressure, but also provides prevention against stroke, kidney disease, anxiety and stress. Potassium also improves muscle strength, metabolism and nerve function.
Rainbow trout is rich in phosphorus
Phosphorus and calcium often work together to help maintain bones and teeth, which is why 85% of the body's phosphorus can be found in bones and teeth. A diet rich in phosphorus stimulates digestion with riboflavin and niacin and helps in the proper elimination of waste products while keeping the kidneys healthy. Phosphorus is also necessary for the growth, maintenance and repair of all tissues.
Rainbow trout is an excellent source of B complex
Thiamin, niacin, vitamin B6, vitamin B12, and pantothenic acid are categorized in the B complex. Water-soluble vitamins play a major role in cellular metabolism. Thiamine helps break down sugars and amino acids.
Niacin helps break down carbohydrates, fats and proteins into energy. It plays a role in removing harmful chemicals from the liver and produces various adrenal glands related to sex and stress.
Vitamin B6 helps the body make several chemicals that help one brain cell communicate with another, that is, the neurotransmitters that affect mood and the body's internal clock.
Vitamin B12 helps the body control homocysteine levels in the blood. Too much of the amino acid homocysteine in the blood is linked to heart disease. People should eat rainbow trout because of its vitamin B12 content, which you cannot find in a plant-based diet.
Pantothenic acid plays a role in breaking down fats and carbohydrates for energy, which is critical for the production of red blood cells and sex- and stress-related hormones.
Rainbow trout is a good source of selenium.
Selenium is an important trace element for normal brain function, a healthy immune system and fertility for both men and women. In combination with vitamin E, selenium can act as an antioxidant and can reduce the risk of cancer and prevent sunburn.
Rainbow trout is low in contaminants.
Fish that contain high levels of mercury have side effects such as kidney damage, mental disorders, brain damage and fatigue, especially in children. Rainbow trout is extremely clean in terms of mercury.
