Researchers have recently scrutinized a wide array of processed foods in Spain, revealing significant insights into the health implications of products boasting high protein content. In a comprehensive study conducted through the Spanish food database BADALI, experts examined 4,325 processed food items to assess their nutritional value. Notably, the study found that plant-based meat analogues were the type of food most likely to carry protein claims, with nearly 70% of these products making such assertions. However, the findings suggest that these claims may not always align with the overall health benefits consumers expect.
The research identified 561 items, accounting for 13% of the examined products, that advertised protein claims. Alarmingly, more than 90% of these foods received a "less healthy" classification. This trend was particularly evident in milk and dairy drinks, where over 61% of those with protein claims were deemed less healthy, compared to just 22% of similar products without such claims. The study highlights a significant concern: while protein claims might attract health-conscious consumers, they frequently mask high levels of fat, sodium, and sugar.
The study further revealed that over half of the products with high protein claims had elevated sodium or fat content. Additionally, about a quarter contained excessive free sugar or saturated fat, while one-fifth included sweeteners. These findings underscore the importance of consumers evaluating food based on comprehensive nutrition labels rather than relying solely on packaging claims.

The implications of this study extend beyond individual dietary choices. Chelsea Johnson, MS, RD, LD, emphasized the need for proper education regarding nutrition choices and advised consumers to scrutinize whole nutrition labels. Johnson noted that processed foods often require added preservatives to maintain consistency and palatability when components like sugar are removed or ingredients like protein are added.

“It’s just not the case. Whenever sugar is taken away or something that could be gritty (like protein) is added, there have to be more preservatives put in to make a food have the right consistency and palatability.” – Chelsea Johnson, MS, RD, LD
Johnson recommends prioritizing whole foods over processed options. For instance, choosing a natural trail mix over a sugary granola bar with added protein offers a healthier alternative without compromising nutritional value.
“[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.” – Chelsea Johnson, MS, RD, LD
