SYSK TRENDING - Are The Added Ingredients In Food All That Bad?
George Zaidan, an MIT-trained chemist and author, discusses the truth about food additives and whether they are as harmful as commonly believed.
Listen on the show ↗Key takeaways
- 👵The advice to avoid foods with unpronounceable ingredients or those not used by your grandmother is often flawed, as many traditional foods were not necessarily healthy, and modern life expectancy is higher.04:34
- 🧪Food additives serve various beneficial purposes, including preventing nutritional deficiencies (like iodine in salt), enhancing flavor, modifying texture (like emulsifiers in peanut butter), and preserving food to extend shelf life.05:44
- ⚖️It's challenging to have foods that are simultaneously healthy, delicious, convenient, and cheap; additives often help bridge the gap between these competing desires, creating necessary trade-offs.06:32
- 🍎The perception that chemicals are inherently bad or that a food with many chemicals is unhealthy is often a side effect of the wellness industry's 'brainwashing,' despite natural foods like apples containing thousands of chemicals.08:24
- 🍔While ultra-processed foods may contribute to the obesity epidemic, it's likely not the sole cause; other factors like decreased smoking rates and changes in home architecture might also play a role.09:41
- 🍬Added sugar in unexpected foods might be designed to encourage more consumption, but sugar itself is a natural substance, and demonizing it while advocating for 'natural' foods can be conflicting advice.11:25

The digest
Mike Carruthers, host of Something You Should Know, interviews George Zaidan, an MIT-trained chemist and author, about the common perception that added ingredients in food are inherently bad. Zaidan, who created National Geographic's web series "Ingredients: The Stuff Inside Your Stuff" and co-wrote MIT's web series "Science Out Loud," challenges the notion that complex chemical names or a long list of ingredients automatically signify an unhealthy product. He emphasizes that many additives serve important functions, from preventing nutritional deficiencies to improving food texture and shelf life.
The "Grandma's Diet" Fallacy
Carruthers opens the discussion by referencing a common piece of advice: if you're looking at a food product to buy and there are ingredients in it that your grandmother didn't use or that you can't pronounce, you shouldn't buy it. Zaidan immediately pushes back on this, stating, "I know a lot of people who swear by that advice, and I don't." He points out that while grandma's diet might have contained easily pronounceable ingredients, it also included items like spam or pound cake, which weren't necessarily great for health. Furthermore, he notes that modern life expectancy is likely higher than that of previous generations, suggesting that idolizing past diets might be misguided. Zaidan argues that the concern isn't just about pronounceability but about the perceived "over-engineering" of food, with artificial colors and unfamiliar chemical names raising red flags for many consumers.
