Researchers have unveiled a concerning trend in the food industry, highlighting that processed foods with protein claims may not be as healthy as consumers are led to believe. The study, conducted on 4,325 processed foods from the Spanish food database BADALI, reveals that a significant portion of these products, despite their protein claims, are nutritionally deficient. This comprehensive analysis underscores the necessity for consumers to scrutinize nutrition labels more closely rather than relying solely on package claims.
The investigation discovered that 13% of the analyzed products, equating to 561 items, boasted protein claims. However, a staggering 90.8% of these were classified as "less healthy." This is particularly alarming given the widespread perception that high-protein foods inherently offer health benefits. The study further identified that over half of these products were laden with high sodium or fat content, and about a quarter contained elevated levels of free sugar or saturated fat.
The findings are especially stark in plant-based meat analogues, where nearly 70% of these products made protein claims. Milk and dairy drinks also featured prominently in the study; those with protein claims were deemed less healthy more than 61% of the time, compared to only about 22% for their non-protein-claim counterparts. Such disparities in health classifications raise questions about the nutritional integrity of these marketed "high-protein" foods.
Jonathan Jennings, MS, MD, concurs with the researchers' observations, stating:
“I agree with the researchers that most people trust the labelling and have no time to research further.”
Jennings highlights a critical gap in public knowledge and accessibility to accurate nutritional information:
“For those people who have time to research they may lack the technical expertise to accurately interpret the labeling […]”
The study's results emphasize the need for strategic decision-making in food choices to avoid unintended health outcomes. Jennings remarks:
“The results of the study remind us that we must be strategic in our choices to avoid unintended health consequences,”
Chelsea Johnson, MS, RD, LD, echoes these sentiments and stresses the importance of nutritional education:
“Potential clinical implications would be ensuring proper education regarding nutrition choices, [and people] choosing to carefully evaluate foods based on the whole nutrition label/facts instead of just relying on the package claims.”
Johnson also points out the general understanding that processed foods should be minimized in one's diet:
“We already know that processed foods aren’t good for you and should be limited in your diet […]”
She advises consumers to opt for whole foods whenever possible:
“[Y]ou want to look for whole foods as much as possible. Instead of a sugary granola bar with added protein, have a trail mix of different nuts that don’t have any added sugar or salt. Instead of meat substitutes that have added protein, have tofu or egg whites if you are a vegetarian, or opt for lean chicken or beef if you are a carnivore.”
The study underscores a critical issue: despite their marketed benefits, processed foods with protein claims often contain undesirable levels of fat, sodium, and sugar. This calls into question the effectiveness of current labeling practices and highlights the need for consumers to be more vigilant.
