A study conducted at the University of Helsinki has shown that partially substituting red and processed meat with pea- and faba bean-based food products can provide sufficient amino acids in the diet without negatively affecting bone metabolism.
Key Findings of the BeanMan Study
Safe Protein Nutrition: The study involved 102 Finnish men who followed a study diet for six weeks.
One group consumed an average of 760 grams of red and processed meat per week, while the other group consumed food products primarily based on legumes like peas and faba beans, equivalent to 20% of their total protein intake.
The study found that decreasing red and processed meat consumption while increasing legume consumption met the protein nutritional needs of the participants.
Bone Health Not Compromised: Researchers did not find any differences in markers of bone formation or resorption between the dietary groups.
Intake of calcium and vitamin D was similar between the groups and aligned with dietary recommendations. Essential amino acid and protein intakes met the recommendations in both groups.
Environmental Impact: Reducing red meat consumption is essential for reducing the environmental impact of diets.
Plant-Based Diets on the Rise: Plant-based diets are becoming increasingly popular, and dietary recommendations are emphasizing the reduction of meat consumption.
Importance of Calcium and Vitamin D: While reducing meat consumption is beneficial for the environment, it’s essential to ensure adequate calcium and vitamin D intake when reducing dairy products from the diet.
Alternative sources for these nutrients include fortified plant-based beverages, yogurt-like products, or dietary supplements if necessary.
The BeanMan study highlights that incorporating legumes like peas and faba beans into the diet as meat alternatives can support protein nutrition without adverse effects on bone health, promoting both personal health and environmental sustainability.
