1-Prevent Heart Diseases :
Researchers found that women who rarely ate fish had a three-fold higher disease risk than those who ate it often. Other research has found that eating fish high in omega-3s can slash blood fat levels, which can contribute to a lower heart-disease risk.
2-Reduce Alzheimer’s Risk:
Eating fish as little as once a week can help preserve gray-matter neurons — the part of the brain linked to memory and cognition .Researchers found that people who eat baked or broiled — but not fried — fish had larger brains and larger cells in the areas of the brain responsible for memory and learning. Scientists believe the larger brain volume can help lower the risk of cognitive decline and Alzheimer’s disease.
3-Improve Skin and Hair:
One of the biggest drawbacks to a low-fat diet is you often deprive your skin and hair of the healthy fat it needs, leaving it dull and dry. The omega-3s in fish are exactly the type of healthy fat to eat to keep your skin looking nourished and your hair shiny. Research has also linked fish and omega-3 consumption to treatment of skin conditions such as psoriasis.
Several studies have found that when taken along with prescription antidepressant medications, the omega-3s in fish are more effective at treating depression that just prescription medication alone. One study of 52 pregnant women found that taking a 300 mg capsule of omega-3s during pregnancy significantly reduced the women’s risk of postpartum depression.
5-Boost Brain Development:
The EFA omega-3 found in salmon and other nutrient-rich fish are essential nutrients for children because they contribute to brain development. Some studies have even found that omega-3 consumption can help soothe symptoms of ADHD. Experts recommend, however, that parents ask their pediatrician before introducing supplements to a child’s diet.
6-Dose of Vitamin D:
Saltwater fish is a sun-less source of vitamin D, which scientists say can help ward off disease, promote bone health, and with the help of the omega-3s in fish, ward off cognitive decline. Just one three-ounce serving of salmon contains 75 percent of your daily recommended amount of the vitamin.
A recent study of 188 men found that those who ate more fresh fish — along with other healthy foods such as fruits, vegetables, and whole grains — had stronger swimmers than those who ate unhealthy diets. Researchers say that more study needs to be done, but preliminary data shows that the better the participant’s diet, the stronger the shape and mobility of the sperm he produced.
