The BeanMan Study in Finland Examines Effects on Male Health of Legume Protein Compared to Meat
Per to Bone health is also not affected by such dietary changes,”, phD student Suvi Itkonen from the Faculty of Agriculture and Forestry. For the BeanMan paper, 102 Finnish men followed a research diet for six weeks.

“Reducing meat consumption is extremely important in terms of environmental impact,”
The participants were divided into the following two groups: One group consumed 760 grams of red and processed meat per week, which accounted for 25% of total protein intake. This amount corresponds to the average protein consumption of Finnish men. The other group consumed legume-based foods, primarily peas and broad beans, which accounted for 20% of total protein intake.
In addition, the amount of red and processed meat consumed per week in this group was within the Planetary Health Diet ceiling (200 g or 5% of total protein intake). Otherwise, the study participants followed their usual diet, but were not permitted to eat any red or processed meat or legumes other than those specified in the study. @breakingthewalls – stock.adobe.com The researchers found no differences between the diet groups in markers of bone formation or resorption.
There were also no differences between the groups in the intake of calcium or vitamin D. Calcium intake was in line with current dietary recommendations and vitamin D intake was very close to recommendations.
The average intake of essential amino acids and proteins corresponded to the recommendations in both groups. An important lifestyle change for the planet “Reducing meat consumption is extremely important in terms of environmental impact,” Itkonen stated.
The plant-based diet is becoming increasingly popular and the in recent weeks updated Nordic Dietary Recommendations as well emphasize the restriction of meat consumption and moderation of milk consumption. “In this study, subjects consumed dairy products as in their usual diet, so their calcium and vitamin D intake remained unchanged. That said, with regard to bone health, it is important to remember that when reducing dairy products in the diet, the intake of calcium and vitamin D from other sources must be ensured.
These sources can be plant-based beverages and yogurt-like products fortified with these nutrients, or dietary supplements when needed,” Itkonen points out. Additional results from the BeanMan study, including those related to lipid metabolism, gut health, and nutrient intake, will be released later.
