Vegetarian diet: truths, myths, and advice from top chefs

Vegetarian diet: truths, myths, and advice from top chefsA0

The vegetarian diet is a eating pattern that excludes meat and fish, but includes plant-based foods such as fruit, vegetables, grains, legumes, and usually also animal products such as eggs and cheese. In fact, those who define themselves as vegetarian usually follow a lacto-ovo vegetarian diet, which allows the consumption of dairy products and eggs. However, there are also lacto-vegetarian and ovo-vegetarian variants, which exclude eggs but allow dairy, or allow eggs but not dairy, respectively. There are also other more restrictive diets, such as the vegan diet, which excludes all animal-derived products, including honey and gelatins, but in common usage are not considered vegetarian. The proliferation of diets with different nuances, however, can generate confusion, so it is always better to ask for specifics from any dinner guests, or clarify your needs with the restaurateur.A0A0

Popularity and data

The vegetarian diet is growing worldwide, both for ethical and environmental reasons and for health reasons. According to Eurispes 2023 data, in Italy about 7.5% of the population defines itself as vegetarian, while vegans represent 2.4%. In Europe, the countries with the highest percentage of vegetarians are Germany, the United Kingdom, and Sweden, while globally India has the largest number of vegetarians, with about 30-40% of the population following this diet for cultural and religious reasons.

Health benefits and risks

Numerous well-conducted, documented, and reviewed studies clearly indicate that a well-balanced vegetarian diet brings many benefits, especially when compared with so-called Westernized diets, which instead include too much animal protein, with a consequent increase in various health risks. Among the pluses of the vegetarian diet are a reduction in the risk of cardiovascular disease, hypertension, type 2 diabetes, and some types of cancer. In addition, a fiber-rich diet promotes gut health and weight control. However, as with any diet that is more restrictive than average, it is wise to pay attention to nutritional balance with the help of experts. Fondazione Veronesi, created by the renowned oncologist and vegetarian Umberto Veronesi, has dedicated a free handbook(https://www.fondazioneveronesi.it/magazine/tools-della-salute/download/quaderni-la-salute-in-tavola/vegetarianismo-una-scelta-etica-di-gusto-e-di-salute) to the topic, very clear and well documented, which removes any doubt about the goodness of this choice for people and the environment.A0A0

Positive effects on the environment

Vegetarian diets bring significant environmental benefits, because they use fewer resources than diets that include meat and fish. Compared with the traditional diet, they can reduce water consumption by up to 50% and generate only a quarter of greenhouse gas emissions, thus contributing to the well-being not only of humans but of the planet. As read in this article on Vanity Fair, extensively documented, “reducing our meat consumption is the single act that would contribute most to saving the environment and improving the climate. Meat and dairy products provide us with only 18% of calories while using 83% of agricultural land, producing 60% of agricultural greenhouse gas emissions, more than all transport, including ships, trucks, and airplanes” (among the various available sources: Science). Of course, this does not mean that we should not also pay attention to the consumption of other foods with a very high environmental impact, even if they are plant-based, such as avocado.

Truths and myths

One of the most widespread myths is that the vegetarian diet does not provide enough protein, but in reality, if, as seen, you eat eggs and dairy products together with all other plant protein sources, this risk does not exist. Another myth concerns supposed physical weakness: many top-level athletes instead follow vegetarian diets without any drop in performance. Examples include tennis champion Novak Djokovic and F1 driver Lewis Hamilton. It is equally true, however, that we are not talking about a healthier diet if it is treated superficially or as a free pass for other unhealthy foods. If, for example, you eat many ultra-processed, nutrient-poor foods, it becomes just as unbalanced as an omnivorous diet.

Historical curiosities

Vegetarianism has ancient roots and has been practiced in different cultures for religious, ethical, and philosophical reasons.

• Antiquity: As early as the 6th century BC, Greek philosophers such as Pythagoras and his followers promoted a vegetarian diet for ethical and spiritual reasons, believing in metempsychosis (the transmigration of souls). Some philosophical schools of ancient India, such as Jainism and Buddhism, also adopted vegetarianism because of the principle of non-violence (ahimsa).
• Roman era: Some Romans, such as Seneca, also followed a vegetarian diet inspired by the teachings of Pythagoras. However, the traditional Roman diet was based mainly on grains, legumes, and vegetables, with meat consumed only occasionally.
• Middle Ages: In the Christian world, many monks followed a vegetarian diet for ascetic reasons. Orders such as the Benedictines and Carthusians limited meat consumption, while in the East Buddhist and Hindu traditions continued to promote a meat-free diet.
• Modern era: In the 17th and 18th centuries, vegetarianism began to spread among some European intellectuals. Leonardo da Vinci was one of the first to condemn meat consumption for ethical reasons. In the 19th century, movements such as the Vegetarian Society, founded in 1847 in the United Kingdom, helped spread the vegetarian diet in the West.
• 20th and 21st centuries: With the boom of the food industry and the increase in environmental and health awareness, vegetarianism has become increasingly widespread. From the 1970s onward, thanks to scientific studies and animal rights movements, vegetarianism has established itself as a common dietary choice worldwide.

Top chefs' tricks for enhancing plant-based ingredients

Cooking vegetarian food is by no means complex. In fact, many traditional dishes from regional Italian and Mediterranean cuisine are vegetarian. There is also Michelin-starred vegetarian dining, such as Joia in Milan, and many well-known chefs have good advice to give on the subject. Let's look at some of them:

1. Yotam Ottolenghi – chef and cookbook author specializing in vegetarian and Middle Eastern cuisine: “The secret of vegetarian cooking is balancing flavors: sweet, salty, sour, and bitter must be in harmony. Spices and fresh herbs can transform even the simplest dish.”

2. Alain Ducasse – French Michelin-starred chef, promoter of sustainable cuisine: “Vegetables are no longer a side dish, but the heart of the plate. Vegetarian cuisine is an explosion of colors, aromas, and textures that offers endless possibilities.”

3. Massimo Bottura – Italian three-star chef of Osteria Francescana: “Vegetables have a precise seasonality and must be respected. Using seasonal produce guarantees the maximum in flavor and nutritional value.”

4. Jamie Oliver – British chef and advocate of healthy cooking: “Vegetables are incredible. If treated with respect and cooked with care, they can bring more satisfaction than any piece of meat.”

5. René Redzepi – chef at Noma, pioneer of Nordic cuisine: “Fermentation, smoking, and marinating are perfect techniques for enhancing the taste of vegetables and turning them into surprising ingredients.”
