Going Vegan? Mind Your B12 and Your Bones! (A Review with Some Limitations)

This review suggests that while vegan diets might reduce the risk of heart problems and metabolic issues, they may also increase the risk of nutritional deficiencies, weaker bones, and mental health problems. It's important to note that most of the cited research is observational and can be influenced by other lifestyle factors associated with veganism. More high-quality research is needed to fully understand the long-term health effects of veganism and to provide practical guidance for those following or considering this diet.

Possible Conflicts of Interest

None identified.

Identified Weaknesses

Reliance on Observational Studies

The review heavily relies on observational studies, which are prone to confounding variables and cannot establish causality. It's difficult to isolate the impact of a vegan diet from other lifestyle factors.

Small Sample Sizes in Some Studies

Some studies cited have small sample sizes, limiting their generalizability to larger populations.

Conflicting Evidence

The review mentions contrasting findings from different studies, creating uncertainty about the true effects of veganism.

Lack of Practical Recommendations

While the review points out potential nutritional deficiencies, it lacks specific recommendations or guidelines for vegans to address them effectively.

Rating Explanation

This review highlights both potential benefits and risks of veganism, which is valuable. However, its reliance on observational studies, presence of conflicting evidence, and lack of specific guidance limit its strength. Therefore, a rating of 3 is appropriate.
