I should eat more cod.



'Besides being an excellent low-calorie source of protein (a four-ounce serving of cod provides 52.1% of the daily need for protein for only 119 calories), cod contains a variety of very important nutrients and has also been shown to be useful in a number of different health conditions.

Cardiovascular Benefits

Fish, particularly cold water fish like cod, have been shown to be very beneficial for people with atherosclerosis and diabetic heart disease. Studies show that people who eat fish regularly have a much lower risk of heart disease and heart attack than people who don't consume fish.

Cod, specifically, promotes cardiovascular health because it is a good source of blood-thinning omega-3 fatty acids, but is also a good source of vitamin B12 and a very good source of vitamin B6, both of which are needed to keep homocysteine levels low.

This is important because homocysteine is a dangerous molecule that is directly damaging to blood vessel walls, and high homocysteine levels are associated with a greatly increased risk of heart attack and stroke(homocysteine is also associated with osteoporosis, and a recent study found that osteoporosis occurred more frequently among women whose vitamin B12 status was deficient or marginal compared with those who had normal B12 status.)

Cod is also a very good source of niacin, another B vitamin that is often used to lower high cholesterol levels, something else that can lead to heart disease.

Protection against Sunburn

Another benefit of omega-3s anti-inflammatory effects may be their ability to protect our skin against sunburn, and possibly, skin cancer.

Although our increased susceptibility to skin cancer is usually blamed on damage to the ozone layer, dietary changes over the last 75 years, which have resulted in excessive consumption of omega-6 fatty acids and insufficient consumption of omega-3 fats, may also be causing human skin to be more vulnerable to damage from sunlight.'
