Plant-Based Diets: Fad Or Future Of Food?

Is a plant-based diet a passing fad? The term veganism was coined in 1944, so it's not a new concept. However, in recent years, it has become more popular, with a 300% increase in the number of Americans following plant-based diets in the last 15 years. This has sparked a debate about whether it is a trend that will eventually fade out or a legitimate lifestyle change. Proponents of plant-based diets argue that it is a healthier option that can help prevent diseases and improve overall well-being. On the other hand, critics argue that it is a confusing and restrictive diet that can lead to nutritional deficiencies. So, is it a fad or here to stay?

The number of people following a plant-based diet is increasing

The Rise of Plant-Based Alternatives

The growing demand for plant-based options has led to the emergence of popular brands like Impossible Foods and Beyond Meat, which offer meatless products that are widely available in restaurants and grocery stores. The success of these companies indicates that plant-based eating is not just a fad. In addition, traditional grocery retailers are offering more plant-based products, and the online vegan market is booming. The Good Food Institute reports that sales of plant-based foods that replace animal products have grown by 29% in just two years, reaching $5 billion.

Environmental Concerns

Another factor contributing to the rise of plant-based diets is the recognition of the environmental impact of the meat production industry. Meat production has been associated with animal methane, pollution, fossil fuel usage, and land and water consumption, making it a significant contributor to the climate crisis. On the other hand, plant-based alternatives have been found to have a much smaller environmental footprint. For example, a study by the University of Michigan showed that Beyond Meat production generates 90% fewer greenhouse gas emissions than U.S. beef production.

Health Benefits

Plant-based diets are also associated with numerous health benefits. They tend to be lower in saturated fat and cholesterol while being higher in fiber, antioxidants, vitamins, and minerals. As a result, they can reduce the risk of heart disease, diabetes, hypertension, obesity, and digestive diseases. Additionally, plant-based diets can aid in weight loss and improve digestion. However, it is important for those following a plant-based diet to ensure they are meeting their protein and vitamin B12 needs, as these nutrients are more commonly found in animal products.

The Future of Plant-Based Diets

While some may argue that plant-based diets are restrictive and challenging to maintain, the increasing availability and popularity of plant-based options suggest that they are here to stay. With the combination of health and environmental benefits, it is likely that plant-based eating will continue to expand in scope and popularity, even among those who are not ready to give up animal products entirely.

Meatless products are becoming more widely available

Consumer demand

Consumer demand for meatless products is increasing, with more consumers seeking out plant-based alternatives to meat for a variety of reasons, including health, sustainability, and ethical concerns. This demand is particularly strong among flexitarians, who are actively seeking to reduce their meat consumption.

Market response

The rise in consumer demand has prompted a response from manufacturers, who are investing in the development and supply of PBMA. This has resulted in an expanded range of meatless products available to consumers, including burgers, ground beef, and sausages.

Taste and texture

A key factor in the increasing availability of meatless products is the improvement in their taste and texture. PBMA are designed to mimic the sensory experiences of eating meat, including its taste, texture, appearance, and aroma. This makes them appealing to a broader range of consumers, including not only vegetarians but also traditional meat-eaters.

Price

The price of PBMA products has also become more competitive with that of meat, although it is still generally higher. However, further technological innovations and increases in supply may help to reduce production costs and make these products more affordable for consumers.

COVID-19

The COVID-19 pandemic also had an impact on the availability of meatless products. The automated production system of PBMA meant that they were less susceptible to labour fluctuations and could provide safer working conditions for employees. In contrast, the meat industry faced significant disruptions, leading to reduced availability and higher prices. This may have encouraged consumers to consider meatless alternatives.

Plant-based diets are better for the environment

A plant-based diet is not just good for our health; it is good for the planet's health. Research has shown that vegan diets result in 75% less climate-heating emissions, water pollution, and land use than diets with more than 100g of meat consumed daily.

Animal husbandry creates as many carbon emissions as the entire transportation sector. By reducing our consumption of animal-based foods, we can significantly lower our water use, as animal husbandry uses more than 50% of freshwater.

A pound of beef, for instance, requires 2000 to 8000 gallons of water to produce, while a pound of tofu requires only 302 gallons. Similarly, a gallon of cow's milk requires 1950 gallons of water, whereas a pound of unprocessed oats needs 290 gallons.

The environmental impact of food production is not limited to water use and emissions. The global food system is responsible for two-thirds of total greenhouse gas emissions, 70% of freshwater use, and 80% of river and lake pollution. About 75% of the Earth's land is used by humans, largely for farming, and the destruction of forests is a major cause of biodiversity loss.

A shift to plant-based diets could add up to 49% to the global food supply without expanding croplands, and it would also reduce the waste byproducts that end up in our oceans.

Vegan options in the restaurant industry are growing

The vegan trend is taking over the world, and the restaurant industry is no exception. The number of people adopting vegan and vegetarian diets is increasing, and this shift in food preferences has led to a growing demand for vegan options on menus. As a result, restaurants and fast-food chains have been quick to adapt, with many now offering dedicated vegan menus or clearly labelled vegan dishes.

According to the Plant-Based Foods Association (PBFA), the presence of plant-based alternatives on US restaurant menus has increased by 62% in the last decade, with nearly half of US restaurants now offering vegan options. This growth is not limited to a particular region, but has spread worldwide, with countries such as the USA, UK, Australia, Germany, and India seeing a significant increase in vegans and vegetarians.

The rise of meat substitutes has played a significant role in the expansion of vegan options in restaurants. Companies like Beyond Meat and Impossible Foods have created plant-based burgers, sausages, and chicken substitutes that faithfully reproduce the taste and texture of meat. These products are not only appealing to vegans but also to flexitarians and meat eaters looking to reduce their meat consumption.

Delivery platforms like Deliveroo and Just Eat have also contributed to the promotion of vegan options in restaurants. These platforms offer filters that allow users to search specifically for vegan-friendly restaurants or dishes, increasing awareness and accessibility.

Even fast-food giants like McDonald's, Burger King, and KFC have embraced the vegan trend. McDonald's has introduced plant-based burgers in some markets, while Burger King's Impossible Whopper, containing a plant-based patty, has attracted both vegans and omnivores. KFC has also tested vegan chicken in the UK, with plans to expand its vegan offerings worldwide.

As consumer preferences continue to shift towards more sustainable and ethical food choices, we can expect to see even more innovative vegan options in the restaurant industry. Restaurants that cater to the growing demand for vegan options will be well-positioned to attract new customers and stay competitive in the market.

Plant-based diets can be good for your health

Plant-based diets are typically centred on whole grains, fruits, vegetables, tubers, and beans and legumes. They are usually low in saturated fat and cholesterol, and high in fibre, antioxidants, vitamins, and minerals.

Health Benefits

Plant-based diets can reduce the risk of heart disease, diabetes, hypertension, obesity, and digestive diseases. They can also help with weight loss, and lower the risk of certain types of cancer.

Research suggests that eating more than five servings of fruits and vegetables a day can increase longevity. Plant-based diets can also reduce the risk of stroke, as meat products, especially red meat, are higher in saturated fat, which can clog arteries.

Nutritional Deficiencies

However, it is important to be aware of potential nutritional deficiencies when following a plant-based diet. The most common deficiency is protein, as meat is a major source of protein. To address this, people on plant-based diets can substitute meat with beans, lentils, peas, and soy products, as well as eggs or low-fat dairy.

Another nutrient that is lacking in plant-based diets is vitamin B12, which is important for energy and strength. Small portions of lean animal protein or B12 supplements can help address this deficiency.

A Gradual Approach

For those considering a plant-based diet, it is recommended to start slowly, perhaps by replacing one meal per week with vegetarian or meatless options. This gradual approach can help individuals adjust their concept of nutrition and make the transition smoother.

Plant-based diets offer a range of health benefits due to their focus on nutrient-dense plant foods. However, it is important to be mindful of potential nutritional deficiencies and make the necessary adjustments to ensure a well-rounded and balanced diet.
