The tuna is loaded with vitamins and nutrients, low in saturated fat and is an excellent source of protein. With talks of the dangers of high mercury content, many have turned away from fish. However, these reports are made in relation to people who eat fish every day.
When eaten in moderation, you can reap the healthy benefits of this tasty fish, while avoiding the negative effects of high levels of mercury in your food. If you aren’t convinced that tuna is a healthy meal choice, here are few nutrition facts that might change your mind:
You always hear about eggs and various meats being a high source of protein, but what about fish? One of the nutritional highlights of tuna is its high protein content. How high in protein content? Try 23 grams in a serving size of three and a half ounces. Talk about a good source of protein to help keep those muscles strong. Protein is also good for the blood, skin, hair and nails.
Tuna has omega-3 fatty acid, which helps prevent high blood pressure. Studies have shown that foods, like tuna, that contain omega-3 fatty acids helped test subjects maintain healthy blood pressure. Those who have yet to develop high blood pressure experience an even stronger beneficial effect from omega-3 fatty acids.
With just two servings of tuna a week, you can lower your triglyceride levels. Why is that a good thing? Triglyceride in the bloodstream indicates the amount of fat being carried. If you have a high level of triglyceride, you are probably also experiencing high levels of low-density lipoprotein (LDL), or “bad cholesterol,” and low levels of high-density lipoproteins (HDL), or “good protein.” To make things simple, you basically want more HDL and less LDL, and eating tuna to lower your triglyceride level is one way to accomplish this.
Good for the Heart
A measure of heart rate function known as heart rate variability (HRV), can be increased by eating tuna. Again, the omega-3 fatty acids of tuna help improve cardiovascular health by increasing HRV. Omega-3 fatty acids also protect your heart from developing abnormal heart rhythms that can be fatal.
Another benefit of the omega-3 fatty acid found in tuna is its ability to reduce the risk of obesity while improving the body’s insulin response. Omega-3 fatty acid is able to stimulate a hormone called leptin, which helps the body’s metabolism while regulating the body’s weight and food intake. Tuna is also low on the glycemic index (GI) with a GI rating of 0, and is low in both calories and fat, making it a good food choice for those struggling with obesity.
The B vitamins present in tuna help to build and maintain red blood cells and increase energy. These water-soluble vitamins increase the rate of metabolism, strengthen the immune system and help keep the skin healthy.
