Recently published systematic reviews and meta-analyses reported that eating at least two servings of fatty fish a week was associated with a reduced risk of cardiovascular disease (CVD) events while fish oil supplements did not show the same effect.
Beta-carotene is an important dietary source of vitamin A for humans. However, the bioavailability and vitamin A equivalency of beta-carotene are highly variable and can be affected by food- and diet-related factors as well as characteristics of the population, such as nutrient deficiencies and genetic variations associated with beta-carotene metabolism.
Recent research has indicated a variety of possible health implications linked to vitamin B12 deficiency without apparent symptoms. Vitamin B12 deficiency is common worldwide.
Rating each and every micronutrient study that is published every day for its quality, reliability and content often requires a good deal of knowledge about nutritional science and biostatistics.

Studies enjoy great popularity among journalists. They cannot be argued against, because they are objective.
In 1912, the Polish biochemist Casimir Funk introduced the term ‘vitamine’ for dietary factors that could prevent diseases such as beri-beri, pellagra or scurvy. Although much time has passed since the heyday of vitamin discovery and many more studies have addressed vitamin functions in human and animal nutrition, there are still uncertainties as to what quantities of vitamins should be consumed by an individual to pro-mote optimal health.
There has been more written and published over the efficacy of vitamin D than over that of most nutrients. Dozens of randomized, controlled trials have been conducted – some large, many small. Unfortunately, the results of many studies have been inconsistent – some positive, some null, and one or two actually negative.
When it comes to research on nutrition and health, media reports are often responsible for much of the confusion and frustration people feel toward the public health community and industry.
Long-chain polyunsaturated fatty acids serve as indispensable structural components of cellular membranes and are important for normal brain and eye development. As a foetus’ intake of fatty acids is mainly dependent on the intake of the expectant mother, there has been growing concern that the low intake of omega-3 fatty acids in Western nations, particularly of DHA, may place infants at risk of deficiency during the critical early period of neurological development.
