Alzheimer’s is a serious brain problem, which leads to the loss of memory, reduction of cognitive functions, and changes in behavior. Though scientists still research its causes, it is believed that many factors contribute to the development of Alzheimer’s.

One important area of study involves nutrient deficiencies, as certain vitamin and mineral deficiencies have been connected with an increased risk for the disease.

Which Deficiency Causes Alzheimer’s?

In this blog, we’ll discuss the nutritional deficiencies most closely linked with AD and the impact of those deficiencies on brain health.

• Vitamin B12 Deficiency

Vitamin B12 is extremely crucial for the brain and nervous health. It is greatly required in the production and maintenance of DNA and red blood cells of the brain. If the supply of B12 becomes scarce within the body, then serious problems related to memory, cognitive function, and even shrinking of the brain tissue over time may appear.

The inclusion in the diet of food containing B12, like fish, meat, eggs, and dairy products, or supplementation, is recommended to avoid deficiency and reduce cognitive decline.

• Vitamin D Deficiency

Vitamin D is another major nutrient that helps in brain health; it helps in regulating the level of calcium in the brain, besides supporting nerve growth and development.

Vitamin D also provides an important role in the reduction of inflammation of the brain-replicating factor for many neurodegenerative diseases such as Alzheimer’s disease.

One can maintain the level of vitamin D either by exposure to sunlight or by consuming foods with vitamin D, such as fortified dairy products, fatty fish, and eggs. In some cases, supplementation might be necessary, particularly for those residing in areas where sunlight is extremely scant.

• Omega-3 Fatty Acid Deficiency

Omega-3 fatty acids, especially DHA, are an important component of brain health. These healthy fats are needed for the structural maintenance and functional operation of cells within the brain. DHA serves critical functions within the brain, where it concentratedly supports memory and learning.

Eating foods with omega-3s balanced, such as fatty fish, along with flaxseeds, chia seeds, and walnuts, will help keep levels healthy to meet the needs of the brain over long periods.

Conclusion

While many factors will affect the development and course of Alzheimer’s disease, nutrient deficiencies will most definitely feature in this equation.

Vitamin B12, D, omega-3 fatty acids, folic acid, iron, zinc, and choline have key roles to play in brain health. The sooner the use of these nutrients is done, the more their scarcity will not lead to or minimize the loss of brain health over time.
