Why Whole Foods Beat Protein Supplements for Better Health

Protein plays a vital role in keeping the body healthy, from repairing tissues to supporting the immune system. Yet experts warn against overdoing it with supplements, urging people to focus on natural food sources instead. Seeds and nuts, for example, pack a surprising protein punch alongside other key nutrients.

A single ounce of hemp seeds delivers 10 grams of protein, making them a rare complete plant-based source with all essential amino acids. Pumpkin seeds follow closely, offering 8 grams per ounce along with magnesium, zinc, iron, and healthy fats. Even peanuts—though not a complete protein—contribute 11 grams per quarter-cup serving, plus heart-friendly unsaturated fats and fibre.

Beyond muscle and metabolism, protein helps stabilise blood sugar, keeps hunger at bay, and influences mood, focus, and digestion. But specialists caution against excessive intake, especially through daily shakes or powders. Dr. med. Katharina Hupa-Breier, a senior physician in nutritional medicine at Hannover Medical School, stresses that most people meet their needs through a balanced diet. Monika Rau, a hepatology expert at University Hospital Würzburg, and Professorin Dr. med. Birgit Terjung, media spokesperson for the DGVS, echo this advice. They recommend prioritising whole foods like legumes, dairy, fish, eggs, and nuts over processed supplements. These natural sources provide protein alongside vitamins, minerals, and other health benefits.

While protein remains crucial for overall health, experts agree that real food should come first. Seeds, nuts, and other whole foods deliver protein without the risks of overconsumption. For most people, a varied diet covers daily requirements without the need for extra supplements.
