Everyone has the desire to stay as youthful as possible, to be healthy, and to be able to enjoy senior life with good cognitive functioning and the ability to remain physically active. Of course, this requires that we take good care of ourselves, and a healthy diet is extremely important. It turns out that having high blood levels of omega-3 fatty acids, which we primarily get from oily fish, is linked to a better chance of healthy aging and a longer life. There is a big difference between omega-3 fatty acids from animal sources and plant sources, according to a large population study that is published in the British Medical Journal.

Iodine is the only mineral, which is compulsorily added to foods because it is can prevent goiter. Studies show that iodine also plays a role in the metabolism, the energy levels, estrogen balance and even helps prevent breast cancer. What is more, iodine can help the body get rid of environmental toxins such as fluoride compounds. Many experts believe that the official iodine recommendations are too low, and it is important to make a note of the fact that refined table salt often contains anti-caking agents like aluminum, and that sea salt is not enriched with iodine.

Although humans generally live longer now, an increasing number of people suffer from chronic diseases. Our medicine consumption is steadily increasing, yet the underlying causes are not addressed, and it is often down to a lack of essential nutrients. Just think of magnesium, a nutrient that is involved in more than 300 different enzyme processes that are important for our nervous system, digestion, muscle function, heart function, blood pressure, bone health, pregnancy, and utilization of vitamin D. This also means that lack of magnesium may be involved in the development of asthma, stress, insomnia, constipation, migraines, neurological diseases, cardiovascular diseases, breast cancer, premature deliveries etc. A recent review article published in Scientifica looks at the importance of magnesium in clinical therapy, and it is vital that magnesium supplements are in a form that the body can absorb and utilize.

Epidemiological studies have led to different results when it comes to vitamin D and its ability to protect against cancer, infections, and various diseases. However, according to a new study published in Cancer Research, this is because magnesium is involved in the activation of vitamin D, on which all cells depend. It therefore does no good to take supplements of vitamin D, if you lack magnesium. And this is exactly the case with many people who eat unhealthy diets, are stressed, use medicine etc.

More and more people get autism. The disease is linked to, among other things, lack of zinc in the childhood. Although it has still not been proved, whether zinc deficiencies during pregnancy can cause autism, scientists have discovered a link between zinc, genes, and the abnormal neurological connections that are associated with autism. The scientists therefore see a whole new potential for treating the condition, but one must also take into account other factors in the environment.

One in nine Danish women gets breast cancer. Diet and lifestyle play a major role, and now an American study shows that omega-3 fatty acids, which are typically found in oily fish and fish oil supplements, may help prevent breast cancer cells from growing and spreading. According to lead investigator Saraswoti Khadge, who is affiliated with the University of Nebraska Medical Center, omega-3 fatty acids support the body’s immune defense and certain anti-inflammatory mechanisms. This study is in line with earlier research, so it may very well be prudent to make sure to get plenty of omega-3 for preventing and treating breast cancer.

Having healthy-looking hair means a lot to most people. Hair that splits at the ends, hair loss, and other hair problems may be caused by stress, hormone changes, and numerous other factors. In this article, we will take a closer look at the diet and its impact on hair health, and we will look at available studies of protein, iron, zinc, selenium, silica, B vitamins, vitamin D and vitamin A. The fact is, we need plenty of these nutrients in a form that the body can absorb and utilize. On the other hand, getting too much can do more harm than good, according to an article in Dermatology Practical & Conceptual, in which the author has analyzed the available research.

Scientists have discussed for quite some time to what extent vitamin D or omega-3 fatty acids from fish oil are able to lower the risk of a heart attack, stroke, and cancer. Although quite a lot of studies have been conducted in this area, there still is no large-scale clinical population study that includes different races. However, an American study has shown that fish oil supplements lower your risk of a heart attack, and large quantities of vitamin D have a long-term preventative effect on different cancer forms. The effect of these two different supplements is also affected by a person’s race.

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.

Salt is a flavor enhancer, and the good news is that salt is not as harmful as previously thought. In fact, salt is essential when consumed in the right quantities, and for most people, it poses no health risk to consume up to five grams – or two and half teaspoons – of salt daily, according to a study that is published in the Lancet. Many people on anti-hypertensive drugs are advised to cut back on their salt intake, but it takes more than that. In fact, it is potassium that controls how much salt the kidneys excrete.

During the winter period, many people catch a cold or are bed-ridden with a bout of the flu. They may consider this to be perfectly natural, but it is actually a sign of a weakened immune defense, and that makes them susceptible to contamination. What matters is to make sure to get plenty of vitamin D, vitamin C, selenium, and zinc, all of which are nutrients that have different functions in the immune system. Some nutrients are also needed in larger quantities to tackle a beginning infection, and it is important to act quickly in order to nip the infection in the bud.
In fact, it is vital for us to be nutritionally bolstered during the winter period, where otherwise harmless virus infections can lead to complications such as herpes, bronchitis, and pneumonia, if the immune system is unable to work full throttle.

Vitamin E is said to be a powerful antioxidant that counteracts wrinkles, reduces the degeneration of joints in rheumatoid arthritis, and even protects against atherosclerosis and cancer. However, studies have shown contradictory results, and the positive effects are most probably a result of luck. Now, a team of international scientists has demonstrated that the effect of vitamin E is not related to the vitamin itself but rather to the effect of a vitamin E-dependent metabolite that is produced in the liver. The researchers see a huge potential in vitamin E therapy that is tailored to fit each person’s individual utilization and metabolism of the nutrient. Vitamin E supplements should contain natural forms of the vitamin to provide the best effect.
