Plant-based meat (PBM) has been gaining popularity due to increasing concerns over health, animal welfare, and environmental issues linked to animal foods. This study aimed to compare the nutrient profile of PBM with equivalent meat products. We conducted a cross-sectional survey of 207 PBM and 226 meat products available from 14 retailers in the UK. We extracted data on energy density, total and saturated fat, protein, fiber, and salt per 100 g from product packaging and calculated the nutrient profile of each product. Compared to meat, PBM had significantly lower energy density, total fat, saturated fat, protein, and significantly higher fiber. Salt content was significantly higher in five out of six PBM categories. Based on the UK’s Nutrient Profiling Model, 14% of PBM and 40% of meat products were classified as “less healthy” (p < 0.001). When considering the UK’s front-of-pack labelling criteria 20% of the PBM and 46% of meat products were considered high in either total fat, saturated fat, or salt (p < 0.001). Nearly three quarters of PBM products did not meet the current UK salt targets. PBM products have a better nutrient profile compared to meat equivalents. However, more progress is needed to reduce salt in these products.

Shifting to dietary patterns rich in plants and low in animal-source foods could substantially lower emissions from the food sector while reducing the global burden of non-communicable diseases. The EAT-Lancet Commission proposed the planetary health diet (PHD) to emphasise plant-forward diets and set global targets to guide an urgently needed food-system transformation. However, the PHD's meat-reduction approach has attracted criticism and prompted debate on the potential micronutrient shortfalls of the plant-forward dietary approach. Since the planet simply cannot sustain human diets defaulting towards animal-based solutions, the objective of this Viewpoint is to provide recommendations that address the shortfalls of the PHD, with an emphasis on plant-based sourcing of food. Using a socioecological approach, along with an Integrative Sustainability Framework to evaluate dietary guidelines, in this Viewpoint we recommend seven key thematic areas for further development of the PHD. These themes relate to the bioavailability of micronutrients from plant-based foods, the inclusion of indigenous foods and practices, fortification and supplementation, cultural inclusiveness, and gender-based differences, a broader perspective on processed foods, and strengthening the concept by integrating the One Health approach.

Background: The current food system has major consequences for the environment and for human health. Alignment of the food policy areas of mitigating climate change and public health will ensure coherent and effective policy interventions for sustaining human health and the environment. This paper explores literature on demand-side policies that aim to reduce consumption of animal-based foods, increase plant-based foods, and reduce overconsumption. Methods: We searched for publications, published between January 2000 and December 2019, considering the above policy domains. Articles were distinguished for type of policy instrument, for topic via keywords and examples were given. Results: The majority of demand-side policies focus on preventing overweight and obesity, using all types of policy instruments including more forceful market-based policies. Hardly any examples of public policies explicitly aiming to lower animal-based foods consumption were found. Policies combining health and sustainability objectives are few and mainly of the information type. Discussion: Moving towards environmentally sustainable and healthy diets is challenging as the implemented demand-side policies focus largely on human health, and not yet on environmental outcomes, or on win-wins. Policies targeting foods from the health perspective can contribute to lower environmental impacts, by indicating suitable animal-based food replacers, and aiming at avoiding overconsumption of energy dense-nutrient poor foods. Preferred policies include a variety of instruments, including strong measures. Conclusions: Working solutions are available to ensure coherent and effective demand side food policies aligning public health and environmental aims. Implementation of aligned and effective policy packages is urgent and needed.

Cakes and biscuits contribute to energy, total and saturated fat and sugar in British diets. So far, the UK government has prompted manufacturers to reduce energy density in these products through a reduction of their sugar content. We conducted a cross-sectional survey of the fat content of cakes and biscuits available in nine UK supermarket chains. In cakes (n = 381), the mean total fat content was 17.9 ± 5.2 g/100 g (39% of the overall energy); range (1.4–35.6 g/100 g) and the average saturated fat content in cakes was 5.9 ± 3.4 g/100 g (13% of the overall energy); range (0.3–20 g/100 g). In biscuits (n = 481), the mean total fat content was 21.8 g ± 6.3 g/100 g (40% of the overall energy); range (0.7–38.9 g/100 g) and the average saturated fat content was 11.4 ± 4.9 g/100 g (23% of the overall energy); range (0.3–22.3 g/100 g). In both cakes and biscuits, total and saturated fat content was positively correlated with energy density. Our results show that cakes and biscuits sold in UK supermarkets are high in total and saturated fat, and that fat content contributes substantially to product energy density. Fat reformulation in these products would effectively reduce energy density, calorie intake and help prevent obesity. Fat reformulation should be implemented simultaneously with sugar reformulation and be focused on saturated fat, as this will have the additional effect of lowering LDL cholesterol.

Manufactured and out-of-home foods contribute to excessive calories and have a critical role in fueling the obesity epidemic. We propose a 20% fat reduction in these foods. To evaluate the potential impact of the proposed strategy on energy intake, obesity and related health outcomes in the population. We used the National Diet and Nutrition Survey rolling program (NDNS RP) data to calculate fat and energy contributions from 46 manufactured and out-of-home food categories. We considered a gradual fat reduction—focusing on SFA—in these categories to achieve a 20% reduction in 5 years. We estimated the reduction in energy intake in the NDNS RP population and predicted the body weight reduction using a weight loss model. We scaled up the body weight reduction to the UK adult population. We estimated reductions in overweight/obesity and type 2 diabetes cases. We calculated the reductions of LDL, ischemic heart disease (IHD), and stroke deaths that could be prevented from the SFA reduction. The selected categories contributed to 38.6% of the population's energy intake. By the end of the fifth year, our proposed strategy would reduce the mean energy intake by 67.6 kcal/d/person (95% CI: 66.1–68.8). The energy reduction would reduce the mean body weight by 2.7 kg (95% CI: 2.6–2.8). The obesity prevalence would be reduced by 5.3% and the overweight prevalence by 1.5%, corresponding to 3.5 and 1 million cases of obesity and overweight, respectively, being reduced in the United Kingdom. The body weight reduction could prevent 183,000 (95% CI: 171,000–194,000) cases of type 2 diabetes over 2 decades. Energy from SFA would fall by 2.6%, lowering LDL by 0.13 mmol/L and preventing 87,560 IHD deaths (95% CI: 82,260–112,760) and 9520 stroke deaths (95% CI: 4400–14,660) over 20 years. A modest fat reduction (particularly in SFA) in widely consumed foods would prevent obesity, type 2 diabetes, and cardiovascular disease.
