Newsletter #005: Late eating linked to increased cancer risk 🍽
Happy weekend, friends! In our 5th edition of the newsletter, we bring you interesting new research connecting light and brain function and some other things worth exploring. We also have a couple of fun product recommendations for those of you who might want to try fermenting veggies at home. We expect to be exploring probiotics and gut microbiota more and more in the coming months.
Tomorrow, Dan leaves for Maine to do some speaking at a fancy hotel on the ocean (rough life) and Maddie (Project Manager, i.e., Jill of all trades) makes a (triumphant) return home to Northern California so that she and Dan can do some business stuff regarding humanOS.me analytics and growth (ahem, excuse to get together and drink Philz Coffee). Enjoy these gems below!
This Week’s Research Highlights
The term "prospective study" refers to a type of observational study in which a group of people is followed over time to see if certain outcomes, such as the development of a disease, occur. The NutriNet-Santé cohort is a large ongoing study in France that collects dietary and lifestyle data from participants to investigate the relationship between nutrition and health outcomes.
The finding that late eaters have an increased risk of breast and prostate cancers suggests that the timing of meals may play a role in cancer development. However, it is important to note that this study only found an association and does not prove causation. Other factors that were not accounted for in the study, such as the type of food consumed, may also play a role in cancer risk.
The study found that individuals who consumed more than 30 types of plants per week had a significantly lower abundance of antibiotic-resistance genes compared to those who consumed less than 10 types of plants per week. Antibiotic resistance is a growing public health concern, and the overuse of antibiotics is one of the main factors contributing to the development of antibiotic resistance. The study's finding suggests that a diverse plant-based diet may help to reduce the prevalence of antibiotic resistance genes in the gut microbiome. The study's methodology involved using DNA sequencing techniques to analyze stool samples from participants and identify the presence of antibiotic resistance genes. The number of plant types consumed per week was self-reported by participants in a survey. While the study's findings are promising, it is important to note that correlation does not equal causation. Other factors, such as the overall quality of the diet and other lifestyle factors, may also play a role in the observed reduction in antibiotic resistance gene abundance.
The text goes on to suggest that inadequate sleep may carry serious economic consequences. It cites a recent study that estimated the total financial cost of insufficient sleep to be $17.88 billion. This cost likely includes expenses related to lost productivity, accidents, injuries, and healthcare costs associated with sleep-related disorders. Inadequate sleep has been linked to a range of negative health outcomes, including obesity, diabetes, cardiovascular disease, and depression. The causes of inadequate sleep are complex and can be related to a variety of factors, such as lifestyle habits, work demands, and medical conditions. The economic impact of inadequate sleep highlights the importance of addressing this issue from a public health and policy perspective. Measures to promote healthy sleep habits and address underlying causes of sleep disruption may have important benefits not only for individual health but also for economic productivity and societal well-being.

Products We Are Enjoying
Ginny says: This includes two wide mouth lids with easy-to-assemble airlocks. You don’t necessarily need an airlock to ferment veggies, but it does make the process a little bit easier and less prone to error or contamination.
Ginny again: Speaking of fermentation, these Korean chili flakes are awesome for making kimchi. As an alternative, I am told that you can also try subbing in a mix of Hungarian paprika and cayenne.
