Around one in six pregnancies results in spontaneous abortion. Although there can be different reasons for this, scientists have found that eating a healthy diet with lots of vegetables, fruit, fish, shellfish, eggs, and grains can lower the risk by over 50 percent. This was shown in a meta-analysis from the University of Birmingham in England. Earlier research shows that selenium, a trace element that many people are deficient in, plays a particularly important role.

Omega-3 and omega-6 fatty acids are vital for our brain function, nervous system, and immune defense but small children get too little of these two essential fatty acids. According to a Canadian study, this increases their risk of chronic inflammation and chronic diseases. The intake of omega-3 from oily fish and shellfish is particularly limited. For children who dislike seafood, a fish oil supplement is worth considering for the sake of their health and development.

Choline is one of the B vitamins and is necessary for our central nervous system, energy turnover, lipid metabolism, and many other functions. It appears to be a somewhat forgotten nutrient, and science now links choline deficiency to Alzheimer’s disease and cardiovascular diseases, according to a study that is published in the journal Aging Cell.

We have relatively large quantities of zinc in our central nervous system where it plays a vital role in various physiological and pathological processes. Zinc is also important for brain development, various gene activities, the formation of new neurons, and the immune defense. What is more, zinc is a vital antioxidant that protects the brain against calcification and cell damage caused by oxidative stress. Zinc deficiency is a global problem and may be involved in a number of different neurological diseases – including stroke, cognitive impairment, Alzheimer’s disease, and depression, according to a new review article that is published in Biomolecules.

PFAS (per- and polyfluoroalkyl substances) are found in building materials, textiles, kitchen utensils, foam from fire extinguishers, and cosmetics. The compounds have even been found in certain foods. The massive PFAS pollution may impair the body’s ability to utilize iodine, especially by affecting thyroid hormones that are essential for our metabolism, according to an article published in Molecular and Cellular Endocrinology. Daily exposure to PFAS may also increase the risk of fetal damage, poor liver function, breast cancer, and other diseases. It also appears that PFAS poisoning increases the need for iodine.

Cancer has become one of the leading causes of death, with rates going up every year. The diet plays a major role and there is a lot of focus on selenium as an anti-cancer agent – both in the form of selenium-enriched functional foods and selenium supplements. Around one billion people worldwide are believed to lack selenium. According to a review article that is published in Foods, however, taking a daily supplement of 100-200 micrograms of selenium yeast can prevent deficiency and reduce some of the most common cancers by fifty percent.
