New study: Plant-based diets have only 30 percent the environmental impact of meat-based diets

Modern people have begun to pay attention to the impact of their diet on the health of the planet, and now, a new study provides a new perspective. After analyzing more than 55,000 actual dietary data, British scientists found that choosing a pure plant diet can greatly reduce the damage to the environment. The study, published July 20 in the journal Nature Food, brings a comprehensive understanding of the link between diet and environmental issues.


The global food system has a huge impact on the planet, emitting one-third of global greenhouse gas emissions. According to research, a plant-based diet can reduce climate heating emissions, water pollution and land use by 75% compared to a diet that consumes more than 100 grams of meat per day. In addition, the plant-based diet was also able to reduce wildlife habitat damage and water use by 66% and 54%, respectively. The study's sample size came from data from 38,000 farms in 119 countries. The research team also found that the "dietary choices" people make have a more important impact on the environment than how and where they are produced.

Emulsified Soy Protein Isolate: An Innovative Force in the Food Industry

图片
Emulsified soy protein isolate represents an innovative achievement in the field of soy protein isolates. It starts with high-quality soybeans and undergoes multiple meticulous purification processes to remove non-protein components such as fats and carbohydrates from the soybeans, resulting in an extremely pure soy protein. The finished product appears as a fine powder with uniform color and an exceptionally high protein content, typically exceeding 90%, far surpassing that of ordinary soy protein products. In terms of advantages, emulsified soy protein isolate boasts superior emulsification stability, rapidly forming a stable emulsion in oil-water systems and preventing oil droplet aggregation and layering. In baked goods, it effectively emulsifies fats, ensuring uniform internal structure, soft texture, and extended shelf life for products like bread and cakes. Its outstanding nutritional enhancement effect is also remarkable. As a high-quality plant protein, it is rich in essential...

The Role of Soy Fiber in Sauces

图片
Sauces play an indispensable role in our diet. Whether it is ketchup that adds color and flavor to dishes or meat sauce that gives dishes a unique flavor, they all add rich flavors to our dining tables with their unique charm. And soy fiber also plays a key role in these sauces, contributing to improving the quality and optimizing the taste of sauces. Thickening effect Soybean fiber can increase the viscosity of sauces, giving them an appropriate flowability and texture. For example, when making salad dressing, adding soy fiber enables the dressing to adhere better to the surface of vegetables. It won't be too thin and runny, thus enhancing the eating experience. In ketchup, it can also make the ketchup maintain a certain shape when squeezed out of the bottle and not quickly flow and deform. Improving taste Soy fiber can endow sauces with a rich taste. It can make the taste of the sauce more full-bodied and layered, avoiding a too single and plain taste. Take broad bean paste as an...
