The rate of autism and ADHD has exploded over the past decades, and the problem comes with an enormous human and socio-economic price tag. A study from the University of Copenhagen has shown that fish oil helps adults with autism and ADHD by improving their attention and working memory. In the study that is published in British Journal of Nutrition, the scientists look closer at omega-3 fatty acids in fish oil and their vital role in the brain and nervous system.
Since the 1950s, the rate of asthma has increased dramatically, especially among children and adolescents. Altered diet habits play a significant role, and now a Swedish population study shows that children who get too little omega-3 and too much omega-6 in their diets have an increased risk of developing asthma later in life. There is also evidence that increased intake of omega-3 fatty acids from oily fish or from fish oil supplements can counteract the inflammatory processes that are seen with asthma.
- which vitamin D2 does not have
Vitamin D2 occurs naturally in foods from the plant kingdom while vitamin D3 comes from animal sources. It is also vitamin D3 that we synthesize in our skin in response to sun exposure. Scientists from the Universities of Surrey and Brighton in Great Britain have now discovered that the two types of vitamin D have entirely different effects. They therefore sow doubts about vitamin D2’s role in human health, whereas vitamin D3 is known for its vital role in helping the immune system in its fight against infections such as COVID-19. Most cells in the body have vitamin D receptors, and the nutrient is also important for cancer prevention, the nervous system, our mood, and a number of other functions. Vitamin D3 from food, supplements, or sunshine must be activated in the body before it can be utilized.
- how to find the best alternatives for strong bones
Many people avoid dairy products because they are lactose intolerant, are vegan, or for other reasons. Milk is a good source of nutrients, especially calcium, but you can easily get enough calcium from other food sources. What is more, it appears that vitamin D, vitamin K2, and the calcium/magnesium ratio is even more important than calcium alone for the structure and maintenance of strong bones. Another thing to remember is that sugar, soft drinks, stimulants, and certain types of medicine can disrupt the bone-building processes. Therefore, having strong bones is about a lot more than dairy products and calcium alone. Finally, don’t forget that daily weight-bearing exercise stimulates bone density.
A team of scientists from Århus University Hospital has discovered that high-doses supplementation with vitamin B1 can help against chronic fatigue that is seen with chronic inflammatory bowel diseases like Crohn’s disease and ulcerative colitis. High doses of vitamin B1 may even help against chronic fatigue in fibromyalgia and other neurological disorders. The scientists have not yet mapped out how the large vitamin doses affect the brain and energy levels and several theories are on the table.
Vitamin B12 is involved in the making of red blood cells. Its role in our nervous system is often overlooked. According to a large Irish study of older people that is published in British Journal of Nutrition, there is a link between lacking vitamin B12 and feeling depressed. Depression is a growing problem that comes with a huge human and socioeconomic price tag, which makes this study highly relevant. It is especially older people, public health servants, and politicians that should pay extra attention to vitamin B12 deficiencies and how to prevent them with simple and inexpensive means. It should also be noted that vegetarian and vegan diets, low stomach acid, and diabetes medication can increase the risk of having low levels of vitamin B12.
