What foods help to strengthen the blood brain barrier?

This comprehensive discussion will cover a vital but often neglected aspect of health, the blood-brain-barrier (BBB). This discussion will explore the benefits of maintaining a healthy BBB, and discuss how diet plays a major role in strengthening this vital structure. In this article, we will provide a list specific foods which can strengthen your BBB as well as some tips on how to get the most out of them.

Why it is important to strengthen the blood-brain barrier

Blood-brain barriers are a barrier that protects the brain against potentially harmful substances while still allowing nutrients to enter. It is important to maintain a healthy BBB for optimal brain functioning as it keeps pathogens and neurotoxins out of the brain. A compromised BBB has been linked to neurological disorders such as Alzheimer's, stroke and multiple sclerosis.

Although there aren't any side effects of boosting the BBB directly, it's important to maintain a healthy diet that doesn’t focus on only foods which benefit the BBB. The overconsumption can cause nutritional imbalances as well as other health problems.

Important Points for Getting Started

It is important to remember that other lifestyle factors such as stress management and exercise play a significant role. Journal of Physiology published a study that highlighted the benefits of physical activity. Chronic stress is also linked to BBB disruption. This highlights the importance of holistic wellness.

Maintaining optimal brain health requires that the blood-brain barriers are strengthened. This goal can be achieved by combining a balanced diet with physical activity and stress management. Don't forget the variety of food listed above and to pay attention to what your body needs.
