In recent years, diets that emphasize animal-based foods like meat, eggs, and dairy (while excluding most plant-based foods) have dominated social media. These diets are characterized by high saturated fat, a lack of fiber, and low phytonutrients. While proponents claim benefits like weight loss and increased energy, health experts express concern about their potential long-term effects. Similar diets have been linked to increased LDL cholesterol and other cardiovascular risks.
The Growth of the Alternative Protein Market: More Balanced Options
Growing awareness of the health and environmental impact of food choices is transforming consumer behavior. The industry, driven by changing consumer habits and growing concerns about health and sustainability, has been gradually adapting to this new scenario.
While vegetarianism and veganism continue to grow, it's the flexitarian movement that's really driving demand for alternative proteins. While 64% of Brazilian consumers are interested in plant-based nutrition (NGO Mercy For Animals, 2021), 28% of Brazilians already identify as flexitarians (The Good Food Institute Brazil, 2022). This group seeks convenience without sacrificing flavor and texture, demanding innovative and enjoyable experiences in their daily diets.
Therefore, "Next-Gen Proteins" are gaining prominence as innovative solutions that meet the demands of an increasingly diverse and demanding consumer base, providing more balanced foods aligned with consumer trends. But what are these next-generation proteins, and how are they shaping the future of the food industry?
Alternative Protein Sources: A New Path
The plant-based protein market has been undergoing a quiet transformation in recent years, with new sources being added to the more traditional ones. Besides soy, other plant-based protein sources, such as cereals like rice and legumes like fava beans, have recently gained prominence, offering unique and advantageous solutions for the food industry.
The protein of the rice, hypoallergenic and highly digestible, is ideal for people with allergies or food sensitivities. Its neutral flavor and smooth texture make it versatile in applications such as protein bars, meal mixes, and gluten-free products. Derived from wheat, the protein in this cereal (gluten) offers specific viscoelastic properties. It is widely used in baked goods, pasta, breaded foods, and meat substitutes. Its functionality and binding capacity make it a valuable choice for a variety of applications.
The protein of broad bean, rich in amino acids and sustainably grown, is a choice aligned with environmental concerns. In addition to meeting the growing demand for clean and sustainable ingredients, fava beans can offer advantages over soybeans and peas, such as a more neutral flavor and better digestibility and consumer acceptance. Their versatility allows them to be used in meat substitutes, dairy alternatives, snacks, and more. Furthermore, fava beans are on the rise in global food product launches.
Global producers of plant-based ingredients are leading the development of these functional solutions that improve the texture, flavor, and nutritional value of plant-based products, and are investing in infrastructure and expansion, building factories dedicated to the processing and production of these proteins.
Plant-Based Protein Nutrition: A Challenge?
From a nutritional perspective, one of the main questions is how plant-based proteins compare to animal-based proteins, and what strategies can be adopted to improve their amino acid profile and functionality in the diet.
It's well known that proteins are widely recognized for their role in providing essential amino acids—the "building blocks" necessary for protein synthesis in the human body. However, unlike animal proteins, many plant-based sources are not considered "complete proteins" because they contain low levels of one or more essential amino acids. This variability, however, is not an insurmountable limitation. Combining different plant-based protein sources can complement amino acid profiles, offering nutritional value equivalent to that of animal proteins.
A classic example in our traditional diet is the combination of rice and beans, which provides a complete protein profile in a simple and affordable way. In industrial applications, an effective approach to maximizing the nutritional quality and benefits of plant-based proteins is to combine different sources in a single formulation. The combination of protein from a cereal and a legume, as well as from rice and beans, is the key. Some widely used combinations include rice and legumes (broad beans, peas, chickpeas, soybeans).
The combination of rice and fava bean proteins has a highly balanced, complementary amino acid profile, potentially providing a higher-quality protein compared to rice combined with other protein sources. Many plant-based protein suppliers know the exact proportions for a suitable combination and often provide technical support to end producers to ensure they deliver a nutritionally superior product. In this way, the combinations improve the overall amino acid profile of the final product, making them ideal for a variety of applications, including meat substitutes.
Human and Planetary Health in Focus
Plant-based proteins, the kings of plant-based diets, have numerous health benefits, particularly when compared to some animal sources. These diets are associated with a reduced risk of chronic diseases such as cardiovascular disease, hypertension, type 2 diabetes, and certain types of cancer. Furthermore, the use of plant-based proteins in a balanced diet can promote satiety and, consequently, help with body weight control. Dietary fiber is often combined with plant-based proteins and also contributes to feelings of fullness and a healthy metabolism. Plant-based proteins, especially when combined with fiber and bioactive compounds, promote intestinal health and contribute to a lower environmental impact, such as reducing greenhouse gas emissions and more efficient use of natural resources.
Future Trends
Production efforts are focused on offering ingredients that improve the sensory and nutritional properties of plant-based products, helping consumers incorporate more plant-based options into their diets.
In addition to traditional plant-based protein sources like soy, emerging proteins like fava beans are emerging for offering unique benefits. These "Next-Gen Proteins" are transforming the market, offering solutions not only for vegan consumers but also for those looking to diversify their protein sources without compromising flavor and sensory experience. By focusing on sustainability, innovation, and quality, the food industry is progressively paving the way for a healthier, more conscious future.
