On sweltering days, few indulgences beckon as invitingly as ice cream. But beyond its sweet allure, could this frozen delight actually contribute to a healthier life?
Renowned oncologist and bioethicist Zeke Emanuel, who played a pivotal role in the development of the Affordable Care Act, suggests this might be the case. In his latest book, Eat Your Ice Cream: Six Simple Rules for a Long and Healthy Life, Emanuel challenges the conventional wellness industry by advocating for simplicity and evidence-backed health practices.
“Mostly anger at the wellness industrial complex,” Emanuel remarks on his motivation. He criticizes the industry for selling costly and scientifically dubious products, from peptides to full-body scans and purported anti-aging supplements.
Emanuel’s book promotes a fundamental approach to health, backed by research. Despite its sugar and fat content, ice cream consumption is linked to a reduced risk of metabolic disease, a phenomenon dubbed the “ice cream paradox.” Studies from 2015 indicate that ice cream, and dairy more broadly, can help prevent Type 2 diabetes, Emanuel notes.

Whey protein, found in dairy, might aid glucose regulation, offering a partial explanation for this association. Emanuel also stresses the importance of fiber and fermented foods for gut health. “Evolution would have gotten rid of them if they weren’t there for a reason,” he says, highlighting foods like yogurt, cottage cheese, and kimchi as beneficial.
Prioritize Sleep and Stay Active
Emanuel emphasizes the significance of daily habits such as exercise, social connections, and adequate sleep for a long, healthy life. A recent study in the Annals of Internal Medicine found that insufficient sleep over six weeks can lead to weight gain, partly due to hormonal imbalances affecting hunger.
“Biologically, sleep is important,” Emanuel asserts, noting its role in memory consolidation, DNA repair, and clearing the brain’s waste. He insists that sleep should never be neglected.
Perhaps most controversially, Emanuel advises against retirement. He highlights the structure, mental challenges, and social interactions that work provides, warning that without these, one might face cognitive decline. Engaging in hobbies or volunteering can offer similar benefits. Research from UC Davis suggests that individuals with a strong sense of purpose are 28% less likely to suffer cognitive impairment.
“There are lots of organizations that need help, and you have skills,” Emanuel says, suggesting volunteering at schools or food banks, taking classes, or joining clubs as ways to meet new people. And a meeting over ice cream is certainly an enjoyable option.
“I enjoy it, that’s for sure,” Emanuel shares, noting chocolate hazelnut as his favorite summer flavor. Moderation, however, remains key.
Six Simple Rules for Health
1. Don’t be a schmuck! Avoid risky behaviors. “Smoking is obviously not good for you. Vaping is also not good for you,” Emanuel cautions. He advises limiting alcohol, avoiding distracted driving, and steering clear of dangerous pursuits like climbing Everest.
2. Talk to people. Initiate conversations for meaningful interactions. Emanuel suggests asking Uber drivers about their origins as a conversation starter. “We’re social beings,” he explains, encouraging proactive engagement.
3. Expand your mind. Stay curious and engaged to fend off cognitive decline. Emanuel recommends lifelong learning as a path to mental vitality.
4. Eat your ice cream. Enjoy a balanced diet with occasional treats. Emanuel advocates for nutritional meals and simple dietary shifts, like reducing sugary snacks.
5. Move it! Regular physical activity, including aerobic and strength training, is crucial. Walking post-meal helps mitigate the harms of sitting.
6. Sleep like a baby. Prioritize quality sleep for overall health. Avoid sleep aids and maintain consistent sleep schedules to improve rest quality.
