Summary

1. Introduction

Vegetarian diets, characterised by the avoidance of meat, meat merchandise and fish and vegan diets, characterised by abstention from all animal merchandise, have turn into more and more standard in Western international locations [1]. There may be additionally a rising physique of epidemiological proof relating to the well being results of vegetarian diets. Potential cohort research have reported that in contrast with meat-eaters, non-meat-eaters might need decrease dangers of weight problems [2], ischemic coronary heart illness [3], diverticular illness [4], cataracts [5] and a few cancers [6], however greater dangers of some fractures [7,8]. Research which have investigated the well being results of substituting pink meat with vegetarian protein sources have noticed decrease dangers of non-alcoholic fatty liver illness [9], coronary coronary heart illness [10], stroke [11] and whole mortality [12].

Complete data on the meals consumption patterns of non-meat-eaters is required to higher perceive the variations in well being outcomes between weight loss program teams. Some earlier research have described meals intakes of vegetarians and vegans [13,14,15,16,17,18,19,20,21,22] and reported that, in comparison with meat-eaters, non-meat-eaters consumed extra soy and different legumes, nuts and seeds, complete grains, greens and fruits and fewer sugary drinks, refined grains, fried meals and alcohol. Nevertheless, some research had been primarily based on small numbers of vegetarians or vegans [14,16,17,18,19,21] and just one examine investigated vegetarian diets within the UK [15]. Due to this fact, there’s a want for extra data on this in research with a lot of vegetarians to additional characterize the meals intakes of non-meat-eaters.

The European Potential Investigation into Most cancers and Diet (EPIC)-Oxford examine collected detailed information on meals intakes in a big cohort of meat-eaters and non-meat-eaters (45%) dwelling all through the UK. The goals of the present examine are to explain and examine intakes of main protein-source meals and different meals teams in common meat-eaters, low meat-eaters, poultry-eaters, fish-eaters, vegetarians and vegans taking part within the EPIC-Oxford examine.

3. Outcomes – “protein comparison between meat and vegetables”

Desk 1. exhibits the participant traits by weight loss program teams for women and men. Roughly one-third of males and one-quarter of girls had been vegetarian or vegan. General, in contrast with common meat-eaters, low meat-eaters, poultry-eaters and non-meat-eaters had been youthful, had a better schooling stage, a decrease socio-economic standing, had been much less more likely to smoke and devour alcohol, had greater ranges of bodily exercise, a decrease BMI, and, expressed as proportion of whole power consumption, greater intakes of carbohydrates and decrease intakes of protein and fats.

Imply intakes of main protein-source meals amongst meat-eaters and non-meat-eaters are proven in Desk 2 (males) and Desk 3 (ladies). The p values for variations between weight loss program teams for all main protein-source meals had been lower than 0.0001, indicating that the meals consumed by the weight loss program teams differed considerably. By definition, vegetarians and vegans didn’t devour pink meat, processed meat, poultry or fish and, as anticipated, consumed extra plant-based protein sources together with legumes and different vegetarian protein options (i.e., tofu, soya, Quorn) in contrast with meat-eaters. Vegetarians consumed essentially the most cheese and vegans consumed the very best portions of plant milk and nuts; greater than 2.5 instances the quantity consumed by the common meat-eaters. This sample was comparable throughout each the non-standardised and the 2000 kcal/day standardised intakes, displaying that the variations between the weight loss program teams for main protein sources had been largely unrelated to variations in whole power consumption.

Common meat-eaters consumed practically a 3rd of their whole power consumption from excessive protein-source meals (meat and fish: 15%; dairy and plant milk: 6%; and cheese, yogurt and eggs: 6%). Vegetarians consumed a couple of quarter of their whole power consumption from excessive protein-source meals (legumes, nuts and vegetarian options: 11%; cheese, yogurt and eggs: 8%; and dairy and plant milk: 5%). Vegans consumed roughly a fifth of their whole power consumption from excessive protein-source meals (legumes, nuts and vegetarian options: 18%; and plant milk: 5%) (Supplementary Desk S3).

Intakes of different meals sources by weight loss program group are proven in Desk 4 (males) and Desk 5 (ladies). General, low and non-meat-eaters consumed greater quantities of greens and complete grain meals and decrease quantities of fried meals, refined grains and sugary drinks than common meat-eaters. Low meat-eaters, poultry-eaters, fish-eaters, vegetarians and vegans every consumed considerably extra brown rice and couscous (with vegans consuming roughly double), and considerably much less fried or roasted potatoes and occasional than common meat-eaters. Low meat-eaters, fish-eaters, vegetarians and vegans consumed considerably much less boiled potatoes, white bread and ice cream and considerably extra wholemeal bread and wholemeal pasta than common meat-eaters (with vegans consuming roughly double). Low meat-eaters, fish-eaters and vegetarians consumed considerably much less fruit squash and spirits in contrast with common meat-eaters. Low meat-eaters, vegetarians and vegans consumed considerably much less white rice than common meat-eaters. Low meat-eaters consumed considerably much less milk desserts than common meat-eaters. Fish-eaters, vegetarians and vegans consumed considerably extra greens and soy desserts than common meat-eaters. Fish-eaters and vegetarians consumed considerably extra different bread and pizza and considerably much less comfortable drinks and weight loss program drinks in contrast with common meat-eaters. Fish-eaters consumed considerably extra crisps than common meat-eaters. Vegetarians and vegans consumed considerably much less wine in contrast with common meat-eaters. Vegans consumed considerably much less white pasta, pizza and tea and considerably extra fruit in contrast with common meat-eaters. Adjusting for schooling and socio-economic standing had minimal affect on these outcomes. Extra sex-specific variations between the weight loss program teams are described in Supplementary Desk S4.

The relative imply consumption of meals teams for low and non-meat-eaters in comparison with common meat-eaters, after adjustment for age, is proven in Determine 1 for males and Determine 2 for ladies. In contrast with common meat-eaters, fish-eaters, vegetarians and vegans consumed greater than double the quantities of legumes, vegetarian options and nuts. Amongst males, vegetarians and vegans consumed 1.5 instances as a lot the sum of brown rice, wholemeal pasta, brown and wholemeal bread than common meat-eaters, whereas solely vegans consumed this quantity amongst ladies.

4. Dialogue

This examine assessed intakes of main protein-source meals and different meals in several teams of meat-eaters and non-meat-eaters dwelling within the UK. Our outcomes point out that there are giant variations in dietary intakes between meat-eaters and non-meat-eaters; non-meat-eaters consumed greater quantities of soy, legumes, pulses, nuts and seeds, complete grains, greens and fruits, and decrease quantities of refined grains, fried meals, alcohol and sugar-sweetened drinks (SSBs). These outcomes had been comparable after we standardised intakes to a 2000 kcal every day weight loss program, indicating that our findings had been largely impartial of power intakes.

Our discovering of a better consumption of all kinds of plant-based meals in low and non-meat-eaters is in line with findings from earlier research. The Adventist Well being Research-2 and the UK Biobank each noticed greater intakes of legumes, vegetarian protein options (e.g., soy, tofu), nuts, complete grains, greens and fruits amongst low and non-meat-eaters [15,20]. Likewise, the NutriNet-Santé examine in France and the Netherlands cohort examine each reported a better consumption of soy, cereals or grains, legumes or pulses, nuts, greens and fruits amongst non-meat-eaters [13,18]. Comparable findings had been reported by smaller research [14,16,17,19,21,22].

It is likely to be anticipated that vegetarians and vegans would change meat with greater intakes of animal-sourced protein options (together with dairy and eggs) and non-animal protein options (together with legumes and nuts), respectively. Nevertheless, our findings recommend that vegetarians and vegans didn’t fully change meat consumption with non-meat protein sources and high-protein plant-sources however elevated their consumption of a giant number of plant-based meals and consumed decrease quantities of excessive protein-sourced meals in contrast with meat-eaters (proportion of whole power from excessive protein-sourced meals was one-third in common meat-eaters, one-quarter in vegetarians; and one-fifth in vegans). Comparatively low protein intakes have been beforehand noticed in vegetarians and vegans on this cohort [27]. For vegans, we famous a better consumption of plant milk and nuts, but in addition the very best consumption of brown rice, wholemeal pasta, couscous and wholemeal bread. This has additionally been noticed in earlier research [15,20]. For vegetarians, we discovered decrease intakes of whole dairy and egg consumption in contrast with meat-eaters. Nevertheless, cheese consumption was the very best in vegetarians. This sample of dairy consumption has been reported beforehand [15,18,19,22]. Cheese will be excessive in power, so it’s attainable that, to realize power necessities of their weight loss program, vegetarians would possibly preferentially change meat with cheese over different decrease calorie dairy merchandise. The findings for egg consumption are much less constant within the literature [13,15,18,20,21,22] and we discovered that egg consumption was low in all weight loss program teams. It’s attainable that on this ‘health conscious’ cohort [27], low egg consumption is because of the perceived healthfulness of plant-based meals, and thus high-protein vegetarian options (together with legumes, soy and nuts) and different plant-based meals (e.g., complete grains) are the popular meals substitutes for meat amongst vegetarians and vegans.

We noticed a decrease consumption of refined carbohydrates, fried meals, alcohol and meals excessive in free sugars (e.g., ice cream and SSBs) amongst low and non-meat-eaters. Comparable findings had been reported by the most important earlier research that additionally discovered decrease consumption of fried potatoes [15,20], refined grains, candy and fatty meals, sugary drinks and alcoholic drinks [13,15,20] amongst non-meat-eaters. These findings recommend that non-meat-eaters is likely to be consuming an general “healthier” weight loss program than meat-eaters.

Nicely-planned vegetarian and vegan diets can adjust to nationwide dietary suggestions [28] and our examine, along with estimates of nutrient intakes in earlier research [27,29], helps this. In comparison with meat-eaters, the non-meat-eaters on this examine consumed a weight loss program that was in line with a lot of the UK’s meals suggestions, i.e., excessive in all kinds of plant-based meals, greens and fruits and low in pink and processed meat, refined grains, sugary meals and alcohol [30].

Essential strengths of this examine embody the massive pattern measurement together with a big proportion of vegetarians and vegans. Moreover, the questionnaire was designed to determine dietary teams [2]. Moreover, earlier work with this cohort means that contributors had a excessive adherence to weight loss program group over time [31]. Nevertheless, some limitations needs to be thought-about when decoding our findings. Dietary consumption was self-reported and could possibly be topic to misreporting, particularly relating to unhealthy meals gadgets corresponding to SSBs [32]. The generalizability of our outcomes is likely to be restricted by the ‘health-conscious’ make up of our cohort and our cohort construction, which is predominantly of white, European descent. It’s also attainable that some vegetarian and vegan merchandise which can be generally consumed weren’t captured in our FFQ. Nevertheless, care was taken to incorporate further plant-based protein meals within the 2010 FFQ.

5. Conclusions

On this giant examine of British women and men, we in contrast intakes of main protein-source meals and different meals teams in common meat-eaters, low meat-eaters, poultry-eaters, fish-eaters, vegetarians and vegans. Our outcomes present that meat-eaters and low and non-meat-eaters don’t solely differ of their meat consumption however of their general dietary consumption; low and non-meat-eaters devour greater quantities of excessive protein meat options, all kinds of different plant-based meals in addition to decrease quantities of refined grains, fried meals, alcohol and SSBs. The dietary intakes consumed by low and non-meat-eaters would possibly clarify the decrease danger for some ailments in these weight loss program teams and can be utilized as a real-life information for future work assessing the well being impacts of changing meat consumption with plant-based meals or dietary suggestions.
