It’s nothing short of a revolution in how we eat, and it’s getting closer every day. Yes, a lot of people are obese, and yes, the definition of “healthy eating” seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, “The foods we like the most will be the most healthy for us.”
Is that going to be a great day, or what?
All this will come to pass, thanks to genomics, the science that maps and describes an individual’s genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly. So, if you’re at risk for heart disease, you won’t just go on a generic low-fat diet. You’ll eat foods with just the right amount and type of fat that’s best for you. You’ll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. “Since people differ in their genetics and metabolism, one diet won’t fit all,” says German.
As complex as all this sounds, it could turn out to be relatively simple.
What are scientists doing?
1) Racing in labs and research centres around the world
2) Asking us to start dieting
3) Creating the perfect diet for us
4) Try and make us taller

So, if you’re at risk for heart disease, you won’t just go on a generic low-fat diet. You’ll eat foods with just the right amount and type of fat that’s best for you. You’ll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. “Since people differ in their genetics and metabolism, one diet won’t fit all,” says German.
As complex as all this sounds, it could turn out to be relatively simple.
Why won’t a common diet fit everybody?
1) Because different people eat different food
2) Because their genes are different
3) Since they differ in genetics and metabolism
4) Because of their different moods

It’s nothing short of a revolution in how we eat, and it’s getting closer every day. Yes, a lot of people are obese, and yes, the definition of “healthy eating” seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, “The foods we like the most will be the most healthy for us.”
Is that going to be a great day, or what?
All this will come to pass, thanks to genomics, the science that maps and describes an individual’s genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly.
