The Benefits of Omega-3 Fatty Acids

While we always hear about omega-3 fatty acids and how they are good for us, just what are they? The experts explain omega-3s are a type of polyunsaturated fat also called “healthy fats.” Research suggests they play a role in protecting us from heart disease and dementia. DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) omega-3s are “the primary polyunsaturated fats in brain cell membranes and have been popularized and successfully marketed as dietary supplements.”

DHA, EPA and DPA omega-3 fatty acids are synthesized by marine organisms such as algae and phytoplankton. They are then consumed by fish, aquatic mammals and crustaceans where the acids are stored in body fat, liver and blubber. When we consume foods from the sea such as salmon, tuna, sardines, mackerel, liver of lean white fish and fish oils, we get the benefits of the omega-3s stored in their bodies.

Another type of omega-3 is ALA derived from plant sources and is the most readily used by the body to create all other types of omega-3 fatty acids. ALAs are found in nuts and seeds like flaxseed, chia seeds, and walnuts as well as oils like canola and soybean. Experts say although ALA can create all forms of omega-3 fatty acids, “the conversion of ALA to DHA and EPA is poor, so they recommend a dietary intake of a combination of foods rich in ALA, EPA, and DHA.

Along with reducing the risk for heart disease, The Medical News Today (MNT) reports other evidence-based benefits of omega-3s include exerting anti-inflammatory effects throughout the human body, lowering blood pressure and cholesterol levels, and improving tolerance to cancer treatments. A study also showed fish oil supplementations protected against major depressive disorders in person between the ages of 15 to 25.

Keeping Seniors Safely Mobile

The Mayo Clinic reminds older adults it is important they take proper precautions to prevent falls. Medical conditions, the resulting medications needed, and a more sedentary lifestyle can result in weaker muscles and balance problems that can lead to a fall. Also please keep in mind, a fall for an older adult can cause injuries that are very serious such as a broken hip, head trauma, or in the most severe cases, death. However, the solution to preventing falls is not to stop moving. The medical experts at the Mayo Clinic explain being inactive is bad for our health regardless of how old we are and it is vital that we keep moving. To that end, they suggest a commonsense six-part plan to keep seniors safely mobile. Their first recommendation is to set up an appointment with your doctor. Bring to the visit a list of all your medications, and be prepared to discuss with your doctor any side effects of the drugs that may put you more at risk for a fall such as anti-depressants or

As We Age, Staying Fit is Important to Mobility and Independence

As we age, staying fit is important to both our mobility and our independence; and even if you haven’t spent your life as a serious fitness buff, experts say it doesn’t mean you can’t start now. However, it is important to check with your healthcare provider before beginning any new exercise. The Harvard Medical School recommends several exercises that provide all-around conditioning and don’t require a gym membership. Any one of them can help keep your weight under control, improve balance and range of motion, strengthen bones, protect joints, prevent bladder control problems, and even ward off memory loss. Swimming is recommended for its low impact on the body as the water’s buoyancy supports the body and takes the strain off painful joints. Dr. I-Min Lee, professor of medicine at Harvard Medical School, explains, “Swimming is good for individuals with arthritis because it’s less weight bearing.” Researchers also report swimming can help improve our mental health. Water aerobics is a

Regular Physical Exercise is Good for Your Bones

Not only is physical exercise good for our heart and cognitive health but it can help older adults stay steady on their feet. Studies show regular physical activity can reduce the risk of falls in older adults at a high risk of falling by nearly one third. Experts explain certain kinds of exercise helps increase muscle mass and bone strength as well as improve balance and coordination, fight off osteoporosis, and reduce the risk for fractures and broken bones. Some of the best exercises are known as weight-bearing, which require a person to carry their weight and work against gravity. Examples include walking, dancing, hiking, climbing stairs, jogging and playing tennis or basketball. Doctors say if you can manage it, increasing your pace during aerobics, jogging and power walking make the exercises even more effective at strengthening bone density. Resistance exercises also work against gravity and help build muscle mass and improve bone strength. Strength training with weights, wei
