Critiques of my work are welcome! Please be aware of the following notes & rules before submitting critique:Be mindful that this content is not all encompassing on the subject at hand and is self-limited for brevity to reach a wider audience. Also, be aware that I receive hundreds of YouTube comments per day, so the only way your critique can be considered is if you follow the steps outlined below. Finally, YouTube auto-deletes links, so I do not see most comments with links attached. RULES:If your comment is rude, you will be banned.If your comment is not about the studies/topics at hand (i.e. extending to other outcomes not discussed) or offers critique with no scientific basis, it is unlikely to receive a response.If you can follow these rules, I will try to address your critique and if there is merit, I will add an AMENDMENT to the content in question and pin it so everyone can see it (thank you!).

Mindsip insights from this episode:
Measure DHA in cell membranes to assess dementia risk
Looking at DHA integrated into your cell membranes is a better long-term marker of consumption and its link to dementia risk than simply measuring it in blood plasma.
Critique social media science for deeper understanding
Headlines on social media often bulldoze over a thousand rivulets of context from a scientific study to reach a conclusion as quickly as possible.
Follow the 10-year omega-3 rule to reduce Alzheimer's risk
Based on one analysis, people who consume DHA for a decade or longer have a 64% reduced risk of developing Alzheimer's disease.
Consume omega-3s daily for cognitive protection against dementia
Strong evidence suggests omega-3s, especially DHA, improve cognitive function and protect against dementia when consumed up to one gram per day long-term.
Maintain consistent omega-3 intake to reduce Alzheimer's risk
Omega-3 consumption needs to be consistent, as the protective relationship with Alzheimer's risk is much more certain and potent with long-term exposure.
Aim for one gram of DHA daily to lower dementia risk
Consuming up to one gram of DHA per day for over 10 years is related to a reduced risk of dementia.
