Can food change our genes?

Food can indeed influence our genes through a process known as epigenetics. Various experts elaborate on how dietary choices impact gene expression and overall health:

1. Dr. David Perlmutter explains that the genes of our gut bacteria influence our genome expression. When we digest plant cells, the RNA from these cells can alter the genetic material of our gut bacteria, which in turn affects our gene expression, metabolic products, and gut health 1.

2. Shawn Stevenson discusses epigenomics, where every bite of food can alter the expression of thousands of genes. He highlights that the foods we eat determine the makeup of our cells and their functions, emphasizing the power of nutrition in gene expression 2 3.

3. Dr. Paul Saladino posits that food acts as a signal to our genetics, impacting epigenetic changes in response to different nutrients. He suggests that certain foods, particularly those higher in linoleic acid, can significantly influence genetic signaling and overall health 4.

4. Julie Foucher talks about how food communicates with our DNA, turning specific genes on and off, impacting metabolic pathways, and contributing to health outcomes. She mentions that processed foods and refined carbs tend to promote inflammation and chronic disease, whereas whole foods have the opposite effect 5.

5. Mark Hyman emphasizes that the impact of food on gene expression occurs in real time. Every bite can switch genes related to disease or health, regulate inflammation, and affect microbiome composition and hormone levels 6.

In summary, the input from these experts strongly suggests that our diet has a significant and immediate impact on our genes, underlining the importance of mindful eating for maintaining optimal health.
