Modelling the replacement of red and processed meat with plant-based alternatives and the estimated effect on insulin sensitivity in a cohort of Australian adults. Br J Nutr 2024; 131:1084-1094. [PMID: 37981891 PMCID: PMC10876457 DOI: 10.1017/s0007114523002659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 11/12/2023] [Accepted: 11/15/2023] [Indexed: 11/21/2023]
Abstract
Dietary guidelines are increasingly promoting mostly plant-based diets, limits on red meat consumption, and plant-based sources of protein for health and environmental reasons. It is unclear how the resulting food substitutions associate with insulin resistance, a risk factor for type 2 diabetes. We modelled the replacement of red and processed meat with plant-based alternatives and the estimated effect on insulin sensitivity. We included 783 participants (55 % female) from the Childhood Determinants of Adult Health study, a population-based cohort of Australians. In adulthood, diet was assessed at three time points using FFQ: 2004–2006, 2009–2011 and 2017–2019. We calculated the average daily intake of each food group in standard serves. Insulin sensitivity was estimated from fasting glucose and insulin concentrations in 2017–2019 (aged 39–49 years) using homoeostasis model assessment. Replacing red meat with a combination of plant-based alternatives was associated with higher insulin sensitivity (β = 10·5 percentage points, 95 % CI (4·1, 17·4)). Adjustment for waist circumference attenuated this association by 61·7 %. Replacing red meat with either legumes, nuts/seeds or wholegrains was likewise associated with higher insulin sensitivity. Point estimates were similar but less precise when replacing processed meat with plant-based alternatives. Our modelling suggests that regularly replacing red meat, and possibly processed meat, with plant-based alternatives may associate with higher insulin sensitivity. Further, abdominal adiposity may be an important mediator in this relationship. Our findings support advice to prioritise plant-based sources of protein at the expense of red meat consumption.

Avocado intake and cardiometabolic risk factors in a representative survey of Australians: a secondary analysis of the 2011-2012 national nutrition and physical activity survey. Nutr J 2024; 23:12. [PMID: 38273346 PMCID: PMC10809541 DOI: 10.1186/s12937-024-00915-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 01/09/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND Avocados are a rich source of nutrients including monounsaturated fats, dietary fibre and phytochemicals. Higher dietary quality is reported in studies of consumers with higher avocado intakes. The present study aimed to examine avocado consumption and cardiometabolic risk measures in a representative sample of Australian adults. METHODS A cross-sectional analysis was performed using Australian Health Survey 2011-2013 (n = 2,736 observations). Day 1 24-hour recall data was used to examine reported avocado intake (whole avocados and avocado-containing products excluding avocado oil) and cardiometabolic risk measures (LDL, HDL, and total cholesterol, triglycerides, apolipoprotein B, HbA1c, plasma glucose, systolic and diastolic blood pressure). T-tests and chi square analyses were conducted between low (5.21 [95% CI: 4.63, 5.79] grams/day) and high (44.11 [95% CI: 35.89, 52.33] grams/day) consumers of avocado. RESULTS 14.7% of Australians were 'avocado consumers' (n = 403 observations). Mean avocado intake was 24.63 (95% CI: 20.11, 29.15) grams per day, with a median intake of 10.40 (IQR: 4.49-26.00) grams per day for those considered 'avocado consumers'. Consumers of avocados had a lower BMI and waist circumference (each, p ≤ 0.001), lower plasma glucose level (p = 0.03), and higher HDL cholesterol (p ≤ 0.001) when compared with non-consumers. A trend towards lower plasma glucose, HbA1c (each, p = 0.04) and higher dietary fibre intake (p = 0.05) was found between high and low consumers of avocado. CONCLUSIONS Our study suggests favourable outcomes for avocado intake and cardiometabolic characteristics of consumers. Future studies should explore glucose homeostasis using a clinical trial design to understand potential relationships between avocado intake and cardiometabolic risk factors.

Abstract
Growing populations, changing dietary preferences and limitations on natural resources have meant that finding an alternative to traditional animal-based protein sources is a priority. Insects have been proposed as a possible solution due to their many benefits including low resource inputs and rich nutritional profile. However, insects are not consumed on a large scale by Australians. Food neophobia (reluctance to try new foods) could be contributing to this delay and as such, this study aimed to explore the role of food neophobia on protein food source habits and willingness to eat insects as food. A total of 601 participants (76.2% female, 23.8% male) completed an online survey which included a questionnaire measuring food neophobia status, participants' self-reported usual protein dietary habits, their previous insect-eating experience, future willingness to eat insects, and potential motivations to include insects in their diet. Results indicated a strong association between food neophobia and participants' dietary choices such as following a vegan or vegetarian diet (p = 0.024). In addition, food neophobia was correlated with a reduced likelihood of previous insect-eating experience (p < 0.001), as well as a decreased willingness to eat insects in the future (p < 0.001). This study provides a greater understanding of the role of food neophobia status and dietary choices in consumers' willingness to eat insects and identifies possible motivating factors that may increase the likelihood of consumers' future insect eating.

Abstract
AbstractPrevious research shows that men eat more meat than women. We explore the extent to which self-rated gender typicality explains differences in meat consumption intentions and behaviour. We recruited a large sample (N = 4897) of Australian men and women to complete an online survey about their attitudes and intentions regarding meat consumption and abstention and measured their self-rated gender typicality (the extent men view themselves as masculine, and women view themselves as feminine). We used moderated regression analyses to investigate self-rated gender typicality as a moderator of the relationship between gender and meat-related variables. We demonstrated that for men, identifying as more masculine was associated with a lower likelihood of reducing meat consumption or considering veg*nism, and a greater belief that eating meat is normal. We also found that men, and those with more gender-typical self-ratings (regardless of gender), viewed meat as more natural, necessary, and nice. These findings suggest that self-rated gender typicality may be relevant for understanding gender differences in meat consumption behaviours. Appeals to adopt low- or no-meat diets may be more effective if they consider the ways Australian diets are interconnected with genders and identities. Increasing acceptance of alternative masculinities, and developing masculinity-friendly advertising of plant-based foods, could be useful in promoting meat reduction.

Abstract
Previous studies have used the traditional average-value method to calculate the usual dietary intake of a population, but the results may be biased due to the measurement errors. The aim of this study was to provide an assessment of the usual micronutrient intake and estimate the prevalence of inadequate intake among Chinese adults. Data from the Chinese Nutrition and Health Surveillance 2015−2017 as well as a total of 72,231 subjects aged 18 years and older were included in the analysis. The 24 h recall method combined with the condiment weighing method were used for three consecutive days to collect daily food and condiments intake. The daily intake of 16 micronutrients was calculated based on the Chinese Food Component Tables. The National Cancer Institute (NCI) method was used to estimate the usual intake of micronutrients, and the prevalence of inadequate intake was estimated using the estimated average requirement (EAR) cut-point method. The results showed that, except for sodium, copper, iron (only for males), vitamin E, and phosphorus, the usual intake of micronutrients in Chinese adults was low, and the prevalence of inadequate intake ranged from 38.67 to 97.63%. The prevalence of inadequate calcium and riboflavin intake was more than 90%, and the proportion of individuals with a usual intake of thiamine, vitamin A, potassium, and selenium below EAR also reached 80%. Manganese, magnesium, vitamin C, and zinc were potentially deficient micronutrients, with the prevalence of inadequate intake ranging from 38.67% to 77.09%. However, usual sodium intake was extremely high with an average of 5139.61 mg/day, and only a quarter of Chinese adults were below the World Health Organization (WHO) recommended value. For most micronutrients, the usual dietary intake declined with age and the prevalence of inadequate intake increased with age. Except for zinc, vitamin A, and B-vitamins, the prevalence of micronutrient deficiencies was higher in females than in males in the same age group (p < 0.05). Therefore, Chinese adults do not receive enough micronutrients. Effective nutrition supplementary strategies and measures are needed to address these problems.

Abstract
Processed meat consumption is increasing in Latin America. While in developed countries processed meat consumption has been associated with cardiovascular diseases and cancer, our region lacks data associated to its consumption and health impact. We characterized processed meat intake and associated factors in a population-based cohort of a Chilean agricultural county, MAUCO. We analyzed baseline dietary data of 7,841 participants, 4,358 women and 3,483 men (38-77 years), who answered an adapted Mediterranean index food frequency questionnaire. Eight percent of the participants presented high processed meat consumption (≥5 times per week). We explored associations of processed meat consumption with participant characteristics using multinomial logistic regression models. Main factors associated with higher consumption were being men, younger and currently employed, and having a high intake (>4 times per week) of red meat (Odds ratio, 2.71, 95% CI 2.10-3.48), butter/cream (1.96, 1.60-2.41), whole-fat dairy products (1.32, 1.04-1.67) and a high intake (≥1 time per day) of sugary snacks/sweets (2.49, 2.04-3.03) and sugary drinks (1.97, 1.63-2.38). Processed meat consumption associated to chronic diseases, particularly cardiovascular disease (Prevalence ratio, 2.28, 95% CI 1.58-3.29). Obesity mediated this association in a proportion of 5.0%, whereas for diabetes the proportion was 13.9%. In this population, processed meat was associated with other unhealthy dietary and lifestyle factors, as well as with chronic diseases, particularly cardiovascular disease.

Abstract
BACKGROUND When aiming to develop dietary messaging to achieve reductions in added sugar intakes, it is necessary to identify key food contributors. Food contributors are not expected to remain static over time. Therefore, the present study aimed to compare the total added sugars (AS) intake and related food sources for adult respondents of two Australian national consumption surveys. METHODS Repeated 24-h recall data from the 1995 National Nutrition Survey (1995NNS, n = 10 851) and the 2011-12 National Nutrition and Physical Activity Survey (2012NNPAS, n = 9341) was used to estimate AS consumption. Food group sources of AS were examined per consumer and per capita and the food group predictors of energy provided by AS were determined. RESULTS A significant difference in total AS intake was identified by age and gender between the surveys (all P < 0.001). Increased variability in food group contributions per consumer was also identified. Nine of the top 20 food groups from the 1995NNS differed (P < 0.001) in their contribution to AS in 2012NNPAS per consumer. Fewer changes were apparent at the population level, with >40% AS coming from only three food groups. Age-stratified analyses showed that the 'sugar, honeys and syrups' and the 'sweetened beverages' food groups were the top contributors between the surveys up to the age group of 70 years. 'Sugar, honey and syrups', 'chocolate and chocolate-based confectionery,' and 'other confectionery' (all, P < 0.001) were significant predictors of AS intake (1995NNS, r2 = 0.755; 2012NNPAS r2 = 0.740). CONCLUSIONS At a population level, food group contributions to AS intakes for Australian adults have not changed substantially over time, yet notable shifts in AS can be seen when targeting only the consumers of these food sources. 'Cake type desserts' appear to be increasingly consumed though 'sweetened beverages' remain a major contributor to AS intakes warranting targeted public health strategies.
