Cognitive Abilities May Increase With Higher Level of Vitamin D in Brain Tissue.

Higher vitamin D levels in brain tissue may be related to decreased incidences of dementia and moderate cognitive impairment finds first-of-its-kind research.

The number of people living with dementia is expected to grow six-fold from 2019 to 2050, reaching over 150 million. Because of this, there is a pressing need for preventative measures to lessen the impact of Alzheimer's disease (AD) and other forms of dementia as the population ages. Research suggests that dietary interventions may slow or avert cognitive decline and dementia by either influencing neuropathology directly or boosting resilience in the face of pathology.

Researchers analysed samples of brain tissue taken from 290 individuals whose cognitive performance had been monitored over an extended period of time and before the onset of any recognised cognitive impairment. The individuals had an average age of 92 years when they passed away over the course of the study.

The study's findings showed that vitamin D may be discovered in brain tissue and that individuals with greater levels of vitamin D in their brains also reported having better levels of cognitive function before they passed away.

Vitamin D, a fat-soluble vitamin and pro-hormone, obtained mostly from food and sun exposure, is one nutrient that has gotten a lot of attention. Low vitamin D levels have also been linked to an increased likelihood of developing an auto-immune illness. Vitamin D affects many bodily functions, including bone health, Skin.

Daily recommended dose of vitamin D

The daily value (DV) for vitamin D is 800 IU (20 mcg). The vitamin D content is listed as a percentage of the DV on the nutrition facts label on food packages. This tells you what amount of your daily vitamin D requirement the food will provide. It’s best to get vitamin D from food or supplements.

7 healthy foods that are high in vitamin D

1. Salmon

Wild salmon often contains more vitamin D than farmed salmon, although both are excellent sources of vitamin D. In a 3.5-ounce (100-gram) portion, farmed salmon has roughly 66% of the DV while wild salmon may contain up to 160% of the DV.

2. Herring / Hilsa and sardines

Herring contains 214 IU of vitamin D per 3.5-ounce (100-gram) serving. Pickled herring, sardines, and other fatty fish, such as halibut and mackerel, are also good sources.

3. Cod Liver Oil
