“…However, the concern was expressed that many women would be unable to identify clearly low or high protein foods, suggesting the need for targeted education. This advice is consistent with the outcomes of a recent large study on ‘Protein Knowledge’ among older women and men 57 . Given the precise nature of the quantitative changes required in protein intake, this warrants particular attention.…”

“…About half of community‐dwelling older adults have poor protein knowledge, 24 which was experienced in our study sample as well. Without increasing knowledge of the importance of protein, the most vulnerable older individuals will be at risk of malnutrition and frailty.…”

BackgroundThe PROMISS randomised controlled trial showed that personalised dietary advice increased protein intake and improved 400‐m walk time and leg strength among community‐dwelling older adults with a low habitual protein intake. This secondary analysis describes and further evaluates the methods and feasibility of the model used to carry out dietary intervention in the PROMISS randomised controlled trial.MethodsIn total, 185 participants (≥65 years, 54% women) with a habitual low protein intake (<1.0 g/kg adjusted body weight/day) in Finland and the Netherlands received personalised dietary advice and complimentary protein‐enriched food products for 6 months with two main objectives: (1) to increase protein intake to ≥1.2 g/kg adjusted body weight/day (energy‐neutral) and (2) to include each day a ‘high‐protein meal’ containing ≥ 30–35 g of protein. The feasibility of the model was evaluated by the adoption of the advice, feedback from the participants, and practical experiences by the nutritionists.ResultsIn all, 174 participants (93.5%) completed the intervention. At the 6‐month follow‐up, 41.8% reached both main objectives of the advice. The participants' general rating for the dietary advice was 8.6 (SD 1.0) (on a scale of 1–10; 10 indicating very good). Sticking to the advice was (very) easy for 79.2% of the participants. The nutritionists perceived the model feasible for the participants except for those with low food intake.ConclusionsThe methods used in this model are mainly feasible, well‐received and effective in increasing protein intake among community‐dwelling older adults with low habitual protein intake.

“…Although not directly investigating protein for exercise recovery, a recent study has also found poor knowledge of dietary protein amongst 1,825 community-dwelling European older adults. Using an online survey, it was determined that 35.3% of the sample did not know what dietary protein was, and low protein knowledge was observed in 902 (49.4%) participants of the total study sample ( 18 ). Of more relevance to the current study is that amongst individuals with low protein knowledge, only 65% responded correctly to the statement that “You need protein in the diet for repairing bones and muscles.” Similarly, a recent feasibility study has shown that giving older adults dietary advice and protein rich food products increased their dietary protein intake over 4 weeks, and most reported that they would continue following the advice on cessation of the study ( 19 ).…”

Older Adults’ Knowledge and Perceptions of Whole Foods as an Exercise Recovery Strategy

et al. 2021

Resistance exercise is a widely advocated treatment for improving muscle strength and performance in older adults. Maximizing the benefit of resistance exercise by ensuring optimal recovery is an important aim and studies are now seeking interventions to expedite exercise recovery in older people. A recovery strategy that has acquired considerable interest is the consumption of protein, and more recently, the consumption of protein-rich whole foods. This study aimed to understand the perspectives of community-dwelling older adults, and determine their knowledge of exercise recovery strategies, their preferences for recovery strategies, and their attitudes toward using whole foods, such as milk as a post-exercise recovery aid. Two hundred ninety-one older adults (74 ± 4 years) were recruited to complete a self-administered online survey. A mixed methods approach was used to gather in-depth data from the cohort. Participants were asked to complete a combination of free-text (open-ended) and multiple-choice questions. Content analysis was conducted on responses to open-ended questions through a systematic classification process of coding. The most common recovery strategies reported were heat treatment, rest, and massage. Nutrition was rarely cited as a recovery strategy. Less than 2% of respondents mentioned nutrition, of these, only half mentioned a protein source. Forty-nine percent expressed negative opinions toward recovery supplements (e.g., “waste of money”) compared to 7% expressing positive opinions. Whole foods such as milk, meat, fish, and fruit, were deemed to be a more acceptable recovery strategy than supplements by 80% of respondents. Those that found whole foods to be equally as acceptable (18%), cited efficacy as their main concern, and those that declared whole foods less acceptable (2%) had no common reason. Despite the high acceptability of whole foods, only 35% were aware that these foods could aid recovery. When asked about milk specifically, the majority of older adults (73%) said this would, or might, be an acceptable exercise recovery strategy. Those that found milk an unacceptable recovery strategy (27%) often cited disliking milk or an allergy/intolerance. In conclusion, whilst whole foods represented an acceptable recovery intervention for older adults, the majority were unaware of the potential benefits of nutrition for post-exercise recovery.
