(4)の thisをある語に置き換えるという問題で模範解答はboiling (their potatoes/them)ですが to boil their potatoesではダメですか?

東京 suggesting a risk linked to, cooking some starchy foods in the microwave, including PANAS cereals and root vegetables. nová nayo si lo era When Betty Schwartz, professor of nutritional sciences at the Hebrew University of Jerusalem, saw her students heating jacket potatoes in the microwave on their lunchbreaks, she noticed small crystals inside their potatoes. rob When she analysed them, she found they were high in the chemical acrylamide, which can be a natural by-product of cooking. Schwartz asked her students to boil their potatoes instead, and found that this didn't create acrylamide, which she says forms in higher temperatures in the microwave. all not ber pb This is a concern because animal studies have shown that acrylamide acts as a carcinogen because it interferes with cell's DNA, but evidence in humans is limited. There is some research to suggest that microwaves are more favourable to the growth of acrylamide than other methods of cooking. "At 100°C (212°F), there's enough energy to alter the automatic joints between molecules to produce a molecule with much higher energy, which can react with DNA, which induces mutations," says Schwartz. "When you have many mutations it can produce cancer." Animal studies have shown this to be the case with acrylamides. 英語 9 the microwave. One way around this is to soak the potatoes in water before putting them in db.cl tenia ng berig adi wad 14 nos
