8 . You are what you eat — and what you eat may be encoded in your DNA. Studies have indicated that your genetics play a role in determining the foods you find delicious or disgusting. “Everything has a genetic component, even if it’s small,” says Joanne Cole, a geneticist and a professor at the University of Colorado School of Medicine. “We know there is some genetic contribution to why we eat the foods we eat. Can we take the next step and actually show the exact position of the regions in the genome (染色体)?”
A new research led by Cole has gotten a step closer. Through a large-scale genomics analysis, her team has identified 481 genome regions that were directly linked to dietary patterns and food preferences. The findings were presented at the American Society for Nutrition’s annual flagship conference.
They were based on a 2020 Nature Communications study by Cole and her colleagues that used data from the U. K. Biobank, a public database of the genetic and health information of 500,000 participants. By scanning genomes, the new analysis was able to home in on 194 regions associated with dietary patterns and 287 linked to specific foods such as fruit, cheese, fish, tea and alcohol.
“This study had a huge number of subjects, so that’s really powerful,” says Monica Dus, an associate professor at the University of Michigan, who wasn’t a part of the new research but studies the relationship between genes and nutrition. “The other thing that I thought was really great is that they have so many different characteristics that they’re measuring in respect to diet. They had cholesterol, the body, socioeconomic backgrounds.”
As the research advances, Dus says such genome analyses could possibly help health care providers — and even policymakers — address larger issues that affect food access and health. “Instead of trying to obsess over telling people to eat this or that, a more powerful intervention is to link it to making sure there aren’t ‘food deserts’ or to make sure that there’s a higher minimum wage — things that have a broader impact,” she says.

Last weekend, I went to Mark’s new house near a forest for a little get-together. After lunch when I was chatting with him and his wife Cody, he asked me, “Hey, Thora, have you ever been to a secret spot?” Before I could even finish saying no, Cody and Mark were already at the door with their jackets on. And the next moment we were heading out into the forest with a camera, a fishing net and a plastic bucket (桶).
We walked through the forest along a path by a small river. Breathing the fresh air, we three talked and laughed all the way.
“Hey! What are you guys doing ?” someone suddenly shouted from behind. Mark and Cody’s eyes immediately widened, and without a word they started running. I had no choice but to follow them, getting my shoes wet and dirty with mud. We probably ran for about 10 minutes before Mark and Cody slowed down. I stopped to catch my breath and asked, “Who was that?”
Mark replied, “The most annoying neighbor ever. There’s no telling what could happen if he caught up with us. He is always making fun of us. I dislike him.” We kept walking on for a few more minutes. Then a beautiful lake appeared before our eyes. “Wow! Amazing!” I shouted and could hardly hold back my excitement. The lake was large and the water was deep and blue, looking so peaceful with tall trees around it.
