Comparing Beans and Beef: Ensuring Bone Health and Protein Intake When Reducing Red Meat Consumption
A recent study conducted by the University of Helsinki delves into the effects of replacing a portion of red and processed meat with pea and faba bean-based foods, and its potential implications for dietary amino acid intake and bone health. As plant-based diets gain traction, maintaining adequate levels of calcium and vitamin D remains a critical concern. The study is complemented by the Leg4Life initiative, which centers on fostering a sustainable and healthier food system through the utilization of legumes.
Fresh research showcases that substituting a fraction of red and processed meat with pea- and fava bean–derived food products leads to a satisfactory amino acid intake within the diet and has no adverse impact on bone metabolism. The study, carried out at the University of Helsinki, involves a detailed exploration of these effects.
“By reducing the consumption of red and processed meat in accordance with the upper limit outlined in the Planetary Health Diet, while simultaneously increasing the consumption of locally cultivated legumes such as peas and fava beans, we can affirm that protein nutrition remains uncompromised. Furthermore, this dietary shift does not undermine bone health,” elucidates Docent Suvi Itkonen from the Faculty of Agriculture and Forestry.
Insight into the BeanMan Study
The BeanMan study enlisted 102 Finnish men who adhered to a specific diet over a six-week period.
One group maintained a weekly intake of 760 grams of red and processed meat, constituting 25% of their total protein consumption. This quantity corresponds to the average protein intake of Finnish men.
The second group consumed food items derived from legumes, mainly peas and fava beans, equivalent to 20% of their overall protein intake. Additionally, the red and processed meat consumption within this group reached the upper limit defined by the Planetary Health Diet (200 g or 5% of their total protein intake).
Apart from this dietary change, the participants followed their habitual diets but were prohibited from consuming red or processed meat, or legumes other than those supplied for the study.
Study Findings and Significance
The study’s findings reveal no discernible distinctions in bone formation or resorption markers between the two dietary groups. Moreover, calcium and vitamin D intake displayed no significant variations. Calcium consumption adhered to current dietary recommendations, and vitamin D intake closely approached these guidelines. Essential amino acid and protein intake averages met the recommendations in both groups.
“It’s important to emphasize the reduction of red meat consumption for its considerable environmental impact,” highlights Itkonen.
As the popularity of plant-based diets surges, the updated Nordic Nutrition Recommendations similarly underscore the importance of limiting meat consumption and moderating dairy intake.
While the subjects in the study adhered to their usual consumption of dairy products, their calcium and vitamin D intake remained unaltered. However, for optimal bone health, Itkonen emphasizes that if dairy consumption decreases, alternative sources of calcium and vitamin D must be ensured. These sources can encompass plant-based beverages, yogurt-like products fortified with these nutrients, or, when necessary, dietary supplements.

Additional insights stemming from the BeanMan study, covering aspects like lipid metabolism, gut health, and nutrient intake, are slated for future publication.

Leg4Life (Legumes for Sustainable Food System and Healthy Life – Palkokasveilla kohti kestävää ruokajärjestelmää ja terveyttä) is a multidisciplinary project funded by the Strategic Research Council of the Academy of Finland. Leg4Life aims to effect a comprehensive societal transformation towards a healthier food system and climate-neutral food production and consumption by increasing the incorporation of legumes. The project encompasses five extensive work packages that span the entire food chain, from cultivation to the dining table, all focused on investigating legumes that flourish within the Finnish boreal conditions.

Frequently Asked Questions (FAQs) about Nutrition
What did the University of Helsinki’s study reveal regarding red meat substitution?
The study showed that replacing some red and processed meat with pea and faba bean-based foods does not compromise amino acid intake or bone health.
How does this study relate to plant-based diets?
As plant-based diets gain popularity, ensuring proper calcium and vitamin D intake remains crucial. The study confirms that such substitutions maintain dietary balance.
What was the approach of the BeanMan study?
The BeanMan study involved 102 Finnish men following specific diets for six weeks. One group consumed red meat, the other legume-based foods, and their health markers were compared.
What were the findings of the study on bone health?
There were no notable differences in bone formation or resorption markers between the dietary groups. Calcium and vitamin D intake also showed no significant variations.
How did the researchers emphasize the importance of red meat reduction?
The reduction of red meat consumption is stressed for its significant environmental impact, advocating for more sustainable dietary choices.
What considerations were highlighted for plant-based diets and bone health?
While dairy consumption was maintained in the study, the researchers noted that if dairy intake decreases, alternative sources of calcium and vitamin D should be ensured for bone health.
Are there future plans for the BeanMan study?
Additional insights on lipid metabolism, gut health, and nutrient intake are anticipated to be published from the BeanMan study in the future.
What is the significance of the Leg4Life initiative?
Leg4Life aims to promote a healthier and climate-neutral food system by increasing the utilization of legumes, contributing to a more sustainable dietary landscape.
