Plant-based diet could save $500 a year? New research reveals surprising cost-effectiveness

Many people believe that switching to a plant-based diet to manage weight may be more expensive, but new research finds the opposite is true.

A new clinical trial published in the Journal of the American Medical Association finds that a plant-based diet may actually lower food bills for overweight adults. In this study, researchers aimed to understand the economic impact of dietary choices, particularly for overweight individuals.


The trial included 200 overweight adults aged between 30 and 55, who were divided into two groups. One group was guided to follow a plant-based diet, while the second group was allowed to maintain their normal eating habits.

Through self-reports, the researchers tracked each participant's weekly food expenditures over a six-month period. Additionally, both groups had access to food discounts and promotions to ensure that the data collected was not influenced by any external economic factors.

Plant-based diet reduces food costs.

After six months, the data showed that participants who followed the plant-based diet spent less on average per week, about 16% less, which equates to savings of about $1.51 per day, compared to the control group. This could potentially save about $500 a year in food expenses.

"We know that a plant-based diet significantly reduces your risk of diseases such as heart disease, diabetes, and obesity, and now We have evidence that choosing beans instead of beef will also save you significant money on your food bill.”

The decrease in daily expenses was primarily due to daily savings of $1.77 on meat and $0.74 on dairy. These decreases were driven in part by increases in spending on vegetables of $1.03, fruits by $0.40, legumes and whole grains by $0.30 a day each, and meat and dairy alternatives.

Overall, the study supports previous research showing that plant-based diets are more cost-effective than diets containing animal products.

The study is part of a growing body of evidence highlighting the economic benefits of a plant-based diet. However, the researchers note that their findings are not conclusive and further research is needed to confirm these claims. Further research is needed to explore how these cost reductions affect broader economic indicators such as health care costs associated with obesity and lifestyle-related diseases.

These new data provide valuable insights for consumers, healthcare providers, and policymakers, opening new avenues for promoting dietary choices that have both economic and health benefits.

Soy Fiber: The Invisible 'Hero' in Canned Foods

图片
 Soybean fiber is mainly derived from by - products generated during the soybean processing, such as soybean dregs and soybean skins. These materials, which were originally likely to be regarded as waste, have transformed into soybean fiber with a variety of excellent properties after a series of complex and sophisticated extraction processes. Currently, there are diverse extraction methods for soybean fiber, mainly including physical methods, chemical methods, and biological methods. In the large family of canned foods, whether it is delicious meat cans or fresh fruit and vegetable cans, soybean fiber plays an indispensable and important role in improving the quality and enhancing the nutrition of canned foods. Magical effects of soybean fiber in canned foods Improving Texture and Taste Soybean fiber has unique gel properties and extremely excellent oil - holding and water - retaining capabilities, and this characteristic is demonstrated most vividly in canned meat products.

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...
