iPB Expert Survey
The International Protein Board (iPB) brings together many of the top researchers and thought leaders in areas related to protein requirements, human health and wellbeing. In 2022, the iPB Expert Survey was completed to capture the opinions of this renowned group on key matters relating to protein nutrition. This survey will be updated annually to capture the most current opinions on key protein matters. The results of the iPB Expert Survey, alongside the most recent clinical evidence, will be used to develop iPB Consensus Statements.
People's Protein Survey
This survey provides a chance for you to have your say. Click here and tell us what you believe regarding protein needs in the diet, for health and performance. The results from this study will provide some insight on general current opinions around the world, which will be reviewed on a regular basis.
The iPB Protein Surveys consists of eight questions addressing the following topics:
-
Do higher protein intake levels pose a health risk?
-
Are base protein requirements set around the world (e.g. RDAs in US/Canada) adequate for optimal health and diet planning?
-
Are based requirements around the world set appropriate for older people as well as vegetarians?
-
Do people trying to lower body weight, particularly body fat, have higher protein requirements?
-
Do people who exercise to build muscle or greater endurance need more protein?
-
Should the methods used to establish requirements be reevaluated and potentially reset?
iPB Experts Survey
The International Protein Board (iPB) brings together many of the top researchers and thought leaders in areas related to protein requirements, human health and wellbeing. The iPB Survey was carried out to captured the opinions of this expert group on key matters relating to protein, the strength of the evidence and current recommendations. The survey will be updated annually, to gauge progress in the area around the world.
2022 Survey
The expert panel were asked to score how much they agree or disagree with a number of statements relating to dietary protein and health, from 1, strongly agree, to 5, strongly disagree.
Protein Requirements for Older People
Statement: The current dietary requirements for protein (e.g. ≈0.8 g/kg body weight or ≈46g women/56g men) stated by several countries is an adequate diet planning level for daily intake for people who are getting older (e.g. 50+ years of age).

General Higher Protein Intake Safety
Statement: Protein intakes as high as two times the RDA (1.6g/kg or 92g for women and 112g for men) pose a kidney, liver and/or bone risk for otherwise generally healthy adults.

Higher Protein Intakes and Weight Loss
Statement: “The current dietary requirements for protein (e.g. ≈ 0.8 g/kg body weight or ≈ 46g women/56g men) stated by several countries is an adequate diet planning level for daily intake for people who are attempting to significantly lower their body weight (e.g. 10% or more) by energy restriction intake.”

Result: 4.82
Protein Intakes for Fitness
Statement: The current dietary requirements for protein (e.g. ≈0.8 g/kg body weight or ≈46g women/56g men) stated by several countries is an adequate diet planning level for daily intake for people who are trying to improve general fitness by exercising and managing energy intake for weight maintenance.
​
Result: 4.45
Adequacy of General Protein Requirements (e.g. RDA) as a Dietary Target Planning Tool
Statement: The current RDA for protein in the US and Canada (0.8g/kg or 46g Women/56g Men) and other countries is adequate for general population health promotion and can be used in diet planning as a daily target intake level.
​
Result: 3.75
Protein Requirements for Endurance Sports
Statement: The current dietary requirements for protein (e.g. ≈ 0.8 g/kg body weight or ≈46g women/56g men) stated by several countries is an adequate diet planning level for daily intake for people who are trying to improve athletic performance through regular endurance training.

Protein Requirements for Vegetarians
Statement: The current dietary requirements for protein (e.g. ≈0.8 g/kg body weight or ≈46g women/56g men) stated by several countries is an adequate diet planning level for daily intake for people who follow a strict vegetarian diet that includes only plant foods and no animal-derived ingredients.
​
Result: 4.45
Protein Intakes and Gastric Bypass
Statement: The current dietary requirements for protein (e.g. ≈0.8 g/kg body weight or ≈46g women/56g men) stated by several countries is an adequate diet planning level for daily intake for people who are recovering from gastric bypass surgery and losing weight.
​
Result: 4.36
Protein Requirements for Building Strength and Muscle Size
Statement: The current dietary requirements for protein (e.g. ≈ 0.8 g/kg body weight or ≈46g women/56g men) stated by several countries is an adequate diet planning level for daily intake for people who are trying to improve muscle mass and/or strength through resistance training.
​
Result: 4.82
Typical Protein Intake to Support General Health
Statement: In general, adults consume adequate protein, either total grams and/or % calories, to promote their best health and wellness status.
​
Result: 3.45
Methods Used to Determine Protein Requirements
Statement: The methods used to establish the initial RDA for protein are still appropriate and do not need to be revisited for general accuracy and/or application across age groups.

Result: 4.09
