Health Experts Warn Against Over-Reliance on Protein-Enhanced Drinks and Supplements

OPA WIRE, Oct 27 (OPA) — Major UK coffee chains, including Starbucks, Costa, and Caffè Nero, have recently expanded their menus to include protein-enhanced lattes, offering up to 25g of protein per serving. This trend reflects a broader market shift as protein supplements move beyond specialized sports nutrition into mainstream consumer products. However, registered nutritionist Emma Bardwell cautions that consumers should evaluate whether these liquid additives are necessary for their specific dietary needs.

The NHS currently recommends an intake of 0.75g of protein per kilogram of body weight daily for adults. While active individuals or older adults may require 1.2–1.6g per kilogram to maintain muscle mass, experts warn that excessive intake can pose risks. Vimoshan Arumuham, a consultant urological surgeon at University College London Hospital, noted that high-protein diets can increase urine acidity and calcium levels, potentially leading to the formation of kidney stones in otherwise healthy individuals.

Nutritionists emphasize that whole foods provide critical nutrients often missing from processed powders, such as fiber, choline, and omega-3 fatty acids. Unlike solid meals, which require chewing and slower digestion, protein shakes may fail to provide the same level of satiety. This discrepancy can lead to increased snacking and higher overall caloric intake, which may undermine weight management goals for some consumers.

While whey protein remains a popular choice for muscle synthesis due to its leucine content, experts advise prioritizing natural sources like eggs, Greek yogurt, and fish. These foods offer a more complex nutritional profile that supports long-term digestive health and disease prevention. Consumers are encouraged to view protein supplements as a secondary option rather than a replacement for a balanced, fiber-rich diet.
