Donating Blood Can Have Several Health Benefits

 

There are a myriad of benefits to donating blood regularly. In addition to helping save lives, getting paid time off from work and enjoying free juice and snacks after donating, there are physical benefits to being a regular donor. If you donate blood several times a year, you are likely in better physical shape than those who do not, and you have a reduced risk for several severe diseases.

Get a Physical

Check up on your own health every time you donate blood. You’ll get a basic physical from a health care worker at the blood collection clinic, so you’ll be able to find out if your blood pressure, pulse, and other vital signs are healthy or not. The Mayo Clinic notes that healthy donors who meet donation requirements are eligible to give blood once every 56 days, so these people can potentially get a physical examination six times a year and completely free of charge.

 

Replenish Blood

Help your body function more efficiently by allowing it to replenish your blood supply regularly. Memorial Sloan-Kettering Cancer Center reports that when you donate blood, your body replaces the blood volume within 48 hours of donation, and all of the red blood cells you lose during donation are completely replaced within four to eight weeks. This process of replenishment can help your body stay healthy and work more efficiently and productively.

Reduce Heart Attack Risk

Improve your cardiovascular health overall by donating blood. Florida Blood Services reports that regular blood donors who donate regularly over years have an 88 percent lower risk of heart attacks and a 33 percent lower risk of any severe cardiovascular event, such as a stroke.

Krill Oil: The New Omega-3

Dr. Oz’s health blog recently posted that a new Omega-3 oil may have emerged that has long been consumed by, get this… whales.  The following is from author Kristin Kilpatrick MS, RD, LD:

“For years, research has demonstrated that omega-3 fatty acids help lower an individual’s risk for heart attack, stroke, certain cancers, depression and overall inflammation. The type of omega-3s to take, however, has not always been clear. Omega-3s are broken down into three main components; ALA, EPA and DHA. EPA and DHA are found in marine sources and are the best-absorbed forms of omega-3 fatty acids. ALA is found in plant-based foods such as walnuts, algae and soybeans. It’s a great source, especially for vegetarians, but may not be as well-absorbed as their marine counterparts.

 

Although the oils found in fatty fish such as tuna and salmon (taken either in whole-food form or in a pill) have been widely popular, many individuals are concerned about other toxins contained in the oils extracted from the farmed versions of these fish

 

Due to this, krill oil has emerged as the next leader in the wonderful world of omega-3s. Just like fish oil, krill oil contains long-chain polyunsaturated fatty acids of the omega-3 family, EPA and DHA. In contrast to fish oil, EPA and DHA from krill oil come attached to phospholipids, mostly phosphatidylcholine. That structural difference leads to better absorption and delivery of DHA to the brain (in animal models). In addition, krill oil contains a potent carotenoid antioxidant, astaxanthin, that may prevent EPA and DHA oxidation.

 

A 2007 study in the Journal of the American College of Nutrition found that 300mg daily supplementation of krill oil resulted in significant decreases in inflammation and arthritic symptoms in cardiac and arthritis patients. Other studies have found that krill oil works as effectively as omega-3s from other sources, yet at a much lower dose. Furthermore, krill oil has been found to raise our good HDL cholesterol and lower our triglycerides as well.

 

Krill oil is found in tiny crustaceans, similar to shrimp, and is the main food source for whales in the Antarctic Ocean. It is found to be a more sustainable source of omega-3s because it’s extracted at the bottom of the food chain and is located in one of the cleanest oceans due to its low occurrence of commercial fishing. These two factors make for an omega-3 source that is virtually free of toxins, metals and PCBs.

 

It’s important to note that krill oil has not been studied as thoroughly as fish oil; however, it may be effective as an alternative until further research can be done on humans. In the meantime, krill oil appears to be safe for human consumption and chockful of benefits.”
