Overview
There’s a crucial mineral essential for fighting diseases, maintaining metabolism, heart health, and aiding in injury recovery. Shockingly, about one billion people worldwide (17% of the population) are deficient in this nutrient.
While a blood test can identify severe deficiency in this mineral, it fails to detect moderate deficiency that still poses health risks. Unfortunately, there isn't a reliable, approved method to measure this nutrient's levels.
However, recent research efforts are underway to change this situation. Here’s what you should be aware of...
In the quest to understand zinc's role in the body, researchers have made significant progress but lack a reliable test to assess a person’s zinc levels. Recognizing this gap, the World Health Organization (WHO) has urged researchers to develop an accurate test for zinc deficiency.
A team of scientists from Cornell and the University of Connecticut has made strides by introducing a comprehensive test to determine an individual’s zinc level.
Challenges in Measuring Zinc Levels
The development of the Zinc Status Index (ZSI) test has been challenging due to the complexity of zinc metabolism. Dr. Elad Tako from Cornell explains, “Because of the complexity and sophistication of zinc metabolism, it is very difficult to accurately measure zinc status.” The ZSI test involves a three-step analysis to determine if you are consuming sufficient zinc for optimal health, as stated by Jacquelyn Cheng.
The ZSI test analyzes:
- Fatty acid ratios: The ratio of specific fatty acids in the body, indicating zinc deficiency if imbalanced.
- Gene expression of proteins: Evaluating gene expression of zinc-dependent proteins in cells.
- Probiotic bacteria: Monitoring changes in gut bacteria composition due to insufficient zinc.
Understanding your zinc status is crucial for your overall health and longevity.
Impact of Zinc Deficiency on Health
Recent studies have highlighted the detrimental effects of zinc deficiency on health. For instance:
- Low levels of zinc and high blood pressure: Research indicates that zinc plays a role in regulating blood pressure by relaxing blood vessels.
- Zinc deficiency and autism development: Lack of zinc may alter brain cell connections, potentially increasing the risk of autism.
- Heart vulnerability to oxidative stress: Insufficient zinc levels can leave the heart susceptible to damage from free radicals.
Boosting Your Zinc Levels
To increase zinc intake, consider consuming foods rich in zinc such as nuts, meat, shellfish, legumes, dairy, and whole grains. If opting for supplements, experts advise not exceeding 40 mg of zinc daily.
While the ZSI test is not yet approved by health agencies, researchers aim to make it accessible to the public soon. Stay informed for updates on this groundbreaking test evaluating blood zinc levels developed by Cornell researchers.
