Iron’s role in sports performance

Iron’s role in sports performanceIron is vital for red blood cells and their ability to carry oxygen, for energy turnover, and for muscle function. For those reasons, iron is highly important for athletes because iron deficiency anemia impairs your performance. Still, iron deficiency is quite common, especially in connection with endurance sports and menstrual bleeding. A plant-based diet and low stomach acid can also increase the risk of becoming iron-deficient. In a new review article that is published in Life, a group of scientists has looked at iron and iron supplementation and how it can affect athletic performance.

Vitamin D’s positive effect on sclerosis

Vitamin D’s positive effect on sclerosisThere is a link between vitamin D deficiency and sclerosis. However, only few studies show whether vitamin D supplements can stop further progression of the disease. A new placebo-controlled study of rats with advanced sclerosis has looked closer at the connection. The study, which is published in Nutrients, shows that vitamin D supplementation counteracts oxidative stress, chronic inflammation, and other processes that are involved in the neurological damage seen with this disease. It is important that vitamin D supplementation aims at optimizing blood levels of the nutrient, which requires higher doses than officially recommended. It also requires enough magnesium to help activate vitamin D and support the nervous system.

Pregnant women’s lack of multiple nutrients harms the development of the baby

Pregnant women’s lack of multiple nutrients harms the development of the babyRefined foods and plant-based diets lack vital nutrients that are highly important for a pregnant woman and the development of her unborn child’s body and brain. This was shown in a large study of mothers from high-income countries, where 90 percent of the participants lacked key nutrients such as vitamin B2, vitamin B6, folic acid, vitamin B12, and vitamin D. These widespread deficiencies have huge health consequences, which may be irreversible for the child. The scientists explain that the problem is made worse by the global push for eating more plant-based diets. Lack of omega-3 fatty acids that are primarily found in oily fish is also common and may harm the development of the child’s brain and increase the risk of postnatal depression in the mother.

We need a lot more vitamin D than the official recommendations

We need a lot more vitamin D than the official recommendationsLack of vitamin D is linked to an increased risk of virus infections, respiratory diseases, cardiovascular diseases, dementia, cancer, and osteoporosis. However, the official recommendations for vitamin D intake are way too low, according to two new studies that were presented at the American Heart Association’s Scientific Sessions in Philadelphia in 2023. In addition, a German study of athletes has shown that it is better to take individually tailored vitamin D supplements to optimize blood levels of the nutrient instead of using a “one-size-fits-all” solution.

Vitamin B12 in breastmilk supports child growth and brain development

Vitamin B12 in breastmilk supports child growth and brain developmentFetuses and children need various nutrients, including vitamin B12, to support the development of the body and brain. According to a study published in The American Journal of Clinical Nutrition, it is crucial to breastfeed the child for a period of at least six months to make sure it gets enough vitamin B12 from the mother’s milk. Most people get enough B12 from animal food sources. However, in countries and populations where people primarily consume plant-based diets, vitamin B12 deficiencies are common. The scientists behind the new study therefore recommend more focus on this specific area and recommend that pregnant and breastfeeding women take vitamin B12 as a supplement in case they don’t get enough from their diet.

Vitamin D supplements prevent dementia

Vitamin D supplements prevent dementiaThe number of older people is increasing rapidly, which means more and more people suffer from different types of dementia. Vitamin D supplementation may help prevent dementia or delay its progression, according to a population study that is published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring. It is important to have optimal blood levels of the nutrient throughout life, simply because it often takes years for dementia to develop, and because vitamin D has many different functions that are relevant for brain health.

Vitamin B12’s key role in healing processes and intestinal inflammation

Vitamin B12’s key role in healing processes and intestinal inflammationIn connection with tissue lesions, vitamin B12 boosts cellular reprogramming to speed up the healing process. This was shown in a Spanish study of mice with ulcerous colitis (bleeding inflammation in the colon). Based on this, the researchers assume that vitamin B12 supplementation may be useful for speeding up the regeneration of damage intestinal tissue. They mention that vitamin B12 may also help reduce the type of complicated inflammation that is seen with ulcerous colitis, and which contributes to the destruction of the intestinal mucosa. In this connection, it is important to remember that vegan diets lack vitamin B12, and that weak stomach acid and the ageing process can also inhibit the absorption of the nutrient.

Selenium protects against dangerous cholesterol

- atherosclerosis, and early death

 Selenium protects against dangerous cholesterolCholesterol is an essential compound with many different functions. However, it can also turn into a potentially dangerous substance if it oxidizes and is embedded in the blood vessel walls. This oxidative process is what eventually leads to atherosclerosis. The trace element selenium protects against atherosclerosis because of its antioxidant properties and because of other mechanisms, according to a review article published in Biomedicine. This is highly relevant in our part of the world where cardiovascular disease is the leading cause of death, and where selenium deficiency is so widespread.

The diet and its influence on migraine

The diet and its influence on migraineMigraine headaches, a problem that affects far more women than men, is one of the diseases that costs most sick days, and there is no medical treatment that can cure the underlying cause. What we eat appears to play a major role, which is because foods such as matured cheese, chocolate, caffeinated beverages, red wine, and monosodium glutamate (MSG) can trigger migraines and headaches. Also, eating an unbalanced diet that is low in specific nutrients such as magnesium, B vitamins, and Q10 can disrupt certain metabolic processes, thereby setting off an attack. This was seen in a new study that is published in Frontiers in Nutrition.

Redheads are better at synthesizing vitamin D

Redheads are better at synthesizing vitamin DRed hair is thought to be a natural part of human evolution in the northern regions, where there is less sunshine. According to a Czech study that is published in Experimental Dermatology, redheads produce more vitamin D than people with other hair colors. Also, redhaired women live longer than women with other hair colors, according to a Swedish study that is published in PLoS One.

Certain medical drugs block coenzyme Q10

Certain medical drugs block coenzyme Q10Q10 is important for cellular energy turnover, and it is also a powerful antioxidant that protects cells and the circulatory system. We synthesize most of our own coenzyme Q10. According to a new in vitro study that is published in Scientific Reports, commonly used medical drugs such as the bisphosphonates, alendronate and zoledronate, for treating osteoporosis block the body’s Q10 synthesis, thereby impairing the energy production in cells, the antioxidant defense, and other metabolic processes. Earlier research has shown that cholesterol-lowering statins lower the endogenous Q10 synthesis, causing side effects such as tiredness, aching muscles, and impotence. It may therefore be a good idea for patients on this type of medication to take a Q10 supplement to prevent or mitigate the adverse effects.
