According to a study that is published in PLoS Medicine’s Special Issue on Dementia shows that low levels of polyunsaturated fatty acids in the brain may speed up the development of Alzheimer’s disease. It is therefore vital not to shy away from dietary fats. What is important, however, is to consume unspoiled sources of omega-3 and omega-6 fatty acids in the proper balance. Polyunsaturated fatty acids have numerous functions in the brain, on which our nervous system, cardiovascular system, memory, learning ability, and lingual skills depend.

A study conducted by the American Heart Association confirms the relation between improved physical condition and feeling younger.

800 people in the ages 21-87 years were followed and tested for a period of eight years to see the relation between their age and physical condition. Once a month, the participants tested their fitness and general physical condition on a treadmill. Not surprisingly, the results showed that a person's basic physical condition decreases with increasing age.

Most people thrive on the idea of staying physically active throughout life, but as we grow older, our skeletal muscle slowly vanishes and our figure changes. This is known as sarcopenia and is one of the main reasons why older people become more fragile and perhaps even disabled. Exercise and diet play a major role, and it seems that the official dietary guidelines are not optimal and should focus more on increased intake of protein as well as lysine, vitamin D, and omega-3 according to a new Canadian study. Earlier research shows that magnesium, selenium, and Q10 are also important for muscle mass and strength.

Q10 is a unique compound with a key role in cellular energy turnover. It also serves as a powerful antioxidant. The body is able to synthesize most of the Q10 that it needs but as we grow older, our endogenous synthesis decreases, making us vulnerable in different ways. Cholesterol-lowering medicine and certain types of disease are also associated with lower levels of Q10 in the body. In a new review article, a group of scientists have scrutinized hundreds of Q10 studies that have been published in the years 2010-2020. They are able to conclude that Q10 is of particular importance to the heart, circulatory system, fertility, muscles, eyes and vision, and the ageing process. Things like migraines, chronic fatigue syndrome, and neurodegenerative diseases such as Parkinson’s and Alzheimer’s disease are also addressed. The body has difficulty with absorbing Q10 from food and supplements so it is recommendable to always choose a pharmaceutical-grade Q10 preparation with documented bioavailability.

Everyone knows that exercise and sports activities are good for you, but overtraining and high-performance sport may increase your risk of oxidative stress, which is associated with acute injuries, inflammation and later risk of neurodegenerative disease such as Alzheimer’s disease and ALS (amyotrophic lateral sclerosis). It is therefore a good idea to take antioxidant supplements, as this may help prevent both acute and chronic injuries. A comprehensive article published in the science journal Nutrients looks closer at the relation between free radicals and antioxidants, which have different functions in connection with various types of physical activity. This is especially the case with vitamins A, C, and E plus selenium and zinc. It is also important to make sure to get enough vitamin D and omega-3 fatty acids for counteracting inflammation and oxidative stress.

It is commonly known that vitamin D plays a vital role for our bones and immune system, and there is even evidence that vitamin D also plays a role in the functioning of our lungs, heart, and muscles. According to a new study, blood levels of vitamin D are determining for how well we utilize our oxygen, and that affects our training capacity and lifespan. The study is published in European Journal of Preventive Cardiology.
