- Over one fourth of today's greenhouse gas emissions are the result of agriculture, with the production of meat representing a large portion of this carbon footprint. As the wealth of low- and middle-income countries continues to increase, the demand for animal-sourced protein, such as dairy and meat products, will escalate. At this point in time, livestock feed alone utilizes almost 40% of the world's cropland. The rapidly increasing world population, coupled with a need for environmental sustainability, has renewed our attention on animal-protein substitutes. Apprehensions over climate change have aided an acceleration in the research and development of alternative proteins, which may replace some animal-sourced protein over time. The alternative dairy and meat industry is developing at a yearly rate of 15.8% and is predicted to reach 1.2 trillion $USD by 2030. This emerging market incorporates new technologies in plant-made protein production, manufacturing of animal proteins by fermentation using microbial bioreactors, and accelerated production of cultivated (also known as cell-based) meat. These new technologies should change the global market drammatically. This article describes the history of the alternative protein industry and its' current status, then offers predictions of future pathways for this rapidly accelerating market. More speculatively, it discusses factors that lead to shifts in consumer behavior that trend toward the adoptation of new technologies.

- BACKGROUND:The effect of marine omega-3 PUFAs on risk of stroke remains unclear.METHODS:We investigated the associations between circulating and tissue omega-3 PUFA levels and incident stroke (total, ischemic, and hemorrhagic) in 29 international prospective cohorts. Each site conducted a de novo individual-level analysis using a prespecified analytical protocol with defined exposures, covariates, analytical methods, and outcomes; the harmonized data from the studies were then centrally pooled. Multivariable-adjusted HRs and 95% CIs across omega-3 PUFA quintiles were computed for each stroke outcome.RESULTS:Among 183 291 study participants, there were 10 561 total strokes, 8220 ischemic strokes, and 1142 hemorrhagic strokes recorded over a median of 14.3 years follow-up. For eicosapentaenoic acid, comparing quintile 5 (Q5, highest) with quintile 1 (Q1, lowest), total stroke incidence was 17% lower (HR, 0.83 [CI, 0.76–0.91]; P<0.0001), and ischemic stroke was 18% lower (HR, 0.82 [CI, 0.74–0.91]; P<0.0001). For docosahexaenoic acid, comparing Q5 with Q1, there was a 12% lower incidence of total stroke (HR, 0.88 [CI, 0.81–0.96]; P=0.0001) and a 14% lower incidence of ischemic stroke (HR, 0.86 [CI, 0.78–0.95]; P=0.0001). Neither eicosapentaenoic acid nor docosahexaenoic acid was associated with a risk for hemorrhagic stroke. These associations were not modified by either baseline history of AF or prevalent CVD.CONCLUSIONS:Higher omega-3 PUFA levels are associated with lower risks of total and ischemic stroke but have no association with hemorrhagic stroke.
