I believe that different people need different diets. Most health practitioners believe everyone should be eating the same foods, though they may argue about what the ideal diet is.

    Bit by bit, though, that viewpoint is changing. A recent publication in JAMA Network Open illustrates this.

    The study used data from long-term follow-up of participants in the Swedish National Study on Aging and Care, which included information about dietary choices. The researchers focused on participants who had Apolipoprotein E4 (APOE4), a genetic variant known to increase the risk of dementia. Apolipoprotein E modifies response to dietary factors, according to this publication.

    People with APOE4 were far less likely to develop dementia if they had included red meat in their diet. With high meat intake, those with the APOE4 genotype were no more likely to develop dementia than those with other genotypes.

    The paper goes on to discuss the possible reasons why those with APOE4 are more likely to require meat in their diet. I found it a fascinating read.
