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】_________
