These days, science may have dissected almost every element of our
diet, but many of us still feel at the sea. Even when sticking to official 【M1】__________
advice, healthy foods that seem to energize one person can cause
another to feel fatigued and bloated. In 2015, scientists from Israel
tracked blood sugar levels of 800 people over several days, making the
surprising discovery individuals’ biological response to identical foods 【M2】__________
varied wildly. Some people had a blood glucose “spike” after eating
sugary ice cream, when others’ glucose levels only increased with starchy 【M3】__________
rice—a finding at odds against conventional wisdom. 【M4】__________
Our bodies’ idiosyncratic handling of nutrients seem to be down to 【M5】__________
our genetics, the microbes in our gut, and variations in our organs’
internal physiology. Clinical trials like those are pioneered by Lind have 【M6】__________
given us general dietary guidelines, but nutrition research tends to
assume all humans are the same, and so can miss the nuances and
specifically needs of the individual. 【M7】__________
In the next 10 years, the emerging field of “personalized nutrition”
will use genetic tests to fill in those gaps to offer healthy eating guidance
tailoring to the individual. Some companies have already tested your 【M8】__________
DNA and offered dietary advice—but the advice can be hit-and-miss. By
2028, we will understand much more about our genetics. Dr. Jeffrey
Blumberg, a professor of nutrition science and policy at Tufts University
in Massachusetts, is one of the most outspoken advocate of this new 【M9】__________
science. He insists that DNA testing will unlock personalized nutrition.
“I’ll be able to tell you what kinds of fruits, what kinds of vegetables
and what kinds of whole grains you should be choosing, or exactly how
often,” he says.
Sadly, personalized nutrition makes cooking meals for the whole
family a little bit taxing. 【M10】_________
