For the primary time, the U.S. authorities is urging individuals to keep away from “extremely processed” meals, which it says are driving diet-related ailments. However this advice places many People in a predicament. Research present many individuals need to cut back the quantity of ultra-processed meals of their diets, however they’ve bother determining which meals fall into that class.
“I feel promoting is admittedly good at making individuals suppose meals are minimally processed once they’re really ultra-processed,” says Alexandra DiFeliceantoniowho research the neuroscience of meals choice at Virginia Tech.
Extremely-processed meals are industrially manufactured merchandise that comprise elements hardly ever present in your kitchen, reminiscent of preservatives, synthetic sweeteners, colorings, pure flavors and emulsifiers. Quite a few research have proven that these meals enhance the danger of a bunch of well being issues, together with diabetes, coronary heart illness, melancholyand weight problems.
“When individuals ask me about ultra-processed meals, they’re usually most confused about grains, carbohydrates, and starches,” says Dr. Dariush Mozaffarianwho leads the Meals is Medication Institute at Tufts College. These meals embody breads, crackers, pretzels, pea snaps, veggie straws, pastas and puffed rice or corn. “Folks wish to know the way to decide on extra healthful variations of those merchandise,” he says.
So Mozaffarian offers his sufferers two sensible guidelines of thumb to observe when deciding on grains and starches: the ten to 1 check and the water check.
1. The ten to 1 check
“A meals ought to have no less than one gram of fiber for each 10 grams of carbohydrate,” Mozaffarian says. For instance, if you happen to’re trying to purchase a granola bar, study the nutrient label. If there are 30 grams of whole carbohydrate within the bar, then there needs to be no less than three grams of fiber in it, too. If not, select a unique bar.
This check, he says, ensures meals aren’t full of solely refined flours and sugars. “So there is a steadiness between refined starches, entire grains, bran, seeds and different different healthful elements,” Mozaffarian explains.
And he says, the meals must also go “the water check.”
2. The water check
Merely take the starchy meals — say a bit of bread, a cracker, pretzel or cereal — and put it in a glass of water. Let it sit within the water for 3 or 4 hours and see what occurs.

Look particularly to see if the grain or starch dissolves or falls aside within the water, he says.
Minimally processed grains, reminiscent of entire wheat breads and metal minimize oats, have the plant’s cell wall nonetheless intact, which surrounds the chains of carbohydrates and kinds a sort of defend or barrier round them. The plant cell wall protects the carbs from dissolving in water.
So if the carbohydrate would not dissolve within the water, then it is doubtless a minimally processed meals, Mozaffarian says. And it is a wholesome selection, as a result of, he says, the cell wall does one thing else necessary: it makes the grain laborious to digest.
After you eat a carbohydrate, enzymes in your mouth and abdomen break down the starch into easy sugars, which then enter your blood stream. In a manner, Mozaffarian says, the water check fashions the method in your digestive tract.
Your enzymes cannot work on carbs once they’re protected by the cell wall. So that you digest minimally processed grains way more slowly than ultra-processed ones. This gradual digestion is nice for you, Mozaffarain says. “It would not overwhelm your liver and the hormones that cope with metabolism.” And in the long term, it reduces your danger of weight acquire and diabetes.
This gradual digestion additionally means the carbohydrate travels additional into your intestine, the place it may well feed the microbes in your massive gut, referred to as the microbiome. You want a wholesome microbiome to thrive.
However, ultra-processed grains and starches do not make it very far in your intestine due to the way in which they’re manufactured, says Dr. Mero B. Morseassistant professor at MD Anderson Most cancers Middle. Firms, in impact, predigest the grains, corn or potato, and within the course of, they take away the plant’s cell wall. “The grain or starch is floor right down to its particular person elements after which re-packaged and glued collectively,” she says.
So the enzymes in your intestine shortly break down the carbohydrates into easy sugars.
“These meals digest actually shortly in your abdomen, and may create a glucose spike,” Morse explains. “And when you will have a glucose spike, insulin ranges are likely to rise.” Over time these spikes can contribute to insulin resistance and finally diabetesshe says.
So while you’re selecting grains, starches and different carbs, you need ones that can maintain collectively each in your intestine — and in a glass of water.
That is the place the water check is available in.

A easy experiment
A number of weeks in the past, my 10-year-old daughter and I baked a loaf of entire wheat bread in our kitchen. And we determined to run it by the water check.
For comparability, we purchased a French baguette from the grocery retailer, which contained preservatives, dextrose, wheat gluten, in addition to “dough conditioner” and “crumb softener.”
We took a bit of each breads, put them into two glasses of water and waited roughly three hours. Then we examined every chunk.
The selfmade entire wheat bread had absorbed some water, however it had stayed intact, and there have been no indicators of the starch dissolving into the water. The water remained clear. Ding, ding, ding! Our selfmade entire wheat bread handed the water check with flying colours.
However the French baguette had remodeled remarkably. “Oh, wow!” my daughter exclaimed, as she pulled the bread from the glass of water. “It is like a sponge, or slime, or Play-Doh!”
The baguette had absorbed an unlimited quantity of water and nearly changed into a kitchen sponge, which you could possibly wring out and use once more. Plus, the water within the cup was cloudy and white as a result of the starch had began to dissolve into it.
Bzzzt! The baguette failed the water check. That end result confirmed that this bread is ultra-processed.
However the water check did one thing else for my daughter. It helped her to grasp — and to see firsthand — how ultra-processed breads could look just like selfmade, however they act fairly in another way inside our our bodies.
“It is sort of gross,” she mentioned, as she squeezed the chunk of ultraprocessed bread like a sponge. “Bread should not be like that.”
