Ice cream lovers around the world may have reason to celebrate. Recent research has suggested that indulging in your favorite flavor might actually have some health benefits. However, before you rush to the nearest ice cream parlor, it’s important to take a closer look at the study and consider other factors that may be at play.

The Study Behind the Buzz

The article in question drew upon a 2018 doctoral thesis that analyzed data from the Nurses’ Health Study I and the Health Professionals Follow-Up Study. These two large-scale observational studies conducted by Harvard University spanned over 20 years and aimed to uncover links between certain diseases, lifestyle factors, and diet.

The researchers focused on participants who reported having type 2 diabetes at the start of the studies, totaling around 16,000 people. These participants provided information about their dietary habits, including their consumption of ice cream. The findings suggested that those who ate ice cream no more than twice a week had a 12 percent lower risk of developing cardiovascular disease compared to those who didn’t eat ice cream.

The Role of Other Factors

However, it’s crucial to note that this link between ice cream and heart disease only became apparent when other aspects of a person’s health, such as their overall diet, were taken into account. This indicates that maintaining a generally healthy diet may be more important in reducing cardiovascular disease risk for people with type 2 diabetes than solely focusing on ice cream consumption.

Another consideration is that participants who reported eating ice cream before joining the study may have altered their diet afterward, potentially due to an increased awareness of their heightened cardiovascular disease risk. This could create the illusion that eating ice cream is linked to a lower risk of heart disease when, in fact, the opposite may be true.

The Limitations of Observational Studies

It’s crucial to understand that the study discussed in the article was observational, meaning it can only demonstrate an association between eating ice cream and a lower risk of heart disease. It cannot definitively prove that ice cream consumption directly decreases cardiovascular disease risk in people with type 2 diabetes.

Conducting a clinical trial where one group consumes ice cream as part of their diet while another group consumes a placebo for ice cream would be required to determine whether ice cream truly has an impact on cardiovascular disease risk. However, such a trial would be challenging to execute practically and is unlikely to occur without substantial funding from the food industry.

The Health Potential of Ice Cream

Surprisingly, there haven’t been many studies specifically examining the effects of ice cream on health. Those that have been conducted typically involved participants consuming small amounts, which didn’t provide sufficient data to draw meaningful conclusions about its impact.

One Italian study did suggest a potential link between consuming more ice cream and an increased risk of non-alcoholic fatty liver, a risk factor for type 2 diabetes and heart disease. However, the researchers also found similar links for other foods, such as red meat, indicating that the overall quality of an individual’s diet may have a greater impact on health than a specific food item.

It’s important to recognize that ice cream is classified as an ultra-processed food, meaning it is typically high in calories, fat, and sugar due to the processing methods involved. Ultra-processed foods have been associated with various health issues, including an elevated risk of developing type 2 diabetes and cardiovascular disease. Nutrition guidelines recommend limiting sugar and fat intake for these reasons, suggesting that excessive consumption of ice cream can have adverse health effects.

However, for those who enjoy dairy products, there is evidence suggesting potential benefits from dairy fat. Research over the past two decades has shown that fermented dairy products, such as certain types of yogurt, and cheese in particular, may lower the risk of heart disease and type 2 diabetes. Additional studies are needed to determine whether ice cream, with its dairy fat content, may offer similar advantages.

Diets rich in calcium-containing foods have also been linked to a reduced risk of type 2 diabetes and heart disease. However, many other foods, including dairy, pulses, and nuts, serve as alternative sources of calcium. These options provide additional nutritional benefits without the high sugar content found in ice cream.

The Bottom Line

While it’s tempting to believe that our favorite foods can have unexpected health benefits, it’s essential to critically analyze the research. Often, the effects of a single food can be exaggerated due to errors in research methods or other influencing factors, such as participants’ overall diet or lifestyle.

Currently, there isn’t sufficient high-quality evidence to definitively claim that ice cream offers any health benefits. However, enjoying a few small portions per week, alongside a balanced diet and regular exercise, is unlikely to cause significant harm.
