In recent years, vegetarianism has swept the globe, and people have finally realized that an unhealthy dietary structure, characterized by excessive meat intake and a low proportion of vegetarian foods, is the primary culprit behind many modern diseases.
Vegetarianism mainly refers to a dietary habit that primarily consists of plant-based foods such as fruits, vegetables, legumes, grains, seeds, and nuts. There are two main types: veganism and semi-vegetarianism. Veganism avoids meat and all animal-derived products such as eggs and dairy. Semi-vegetarians do not eat meat but consume some animal products like eggs and dairy to meet their protein needs, and their nutritional requirements can be satisfied. However, long-term vegans are more prone to deficiencies in nutrients like Vitamin B12, calcium, and zinc. So, how exactly should one eat a healthy vegetarian diet?
One: Designate Vegetarian Days. You can choose 1 to 2 days a week to eat completely vegetarian, while maintaining a mixed diet of meat and vegetables on other days. Fixed vegetarian days can improve eating habits, reduce the burden on the digestive system, and give your body a regular "cleanse." Alternatively, you can have 1 to 2 vegetarian meals daily, with dinner being the most effective. This way, you can enjoy the health benefits of a vegetarian diet while still meeting your nutritional needs.
Two: Diversify Your Ingredients. To ensure a balanced and complementary nutritional intake, try to include staple foods, vegetables, fruits, legumes, and nuts every day. Consume at least 15 different types of food daily, and pay attention to a colorful mix of foods—red, green, yellow, black, and white. It's particularly important to increase your intake of black-colored foods like black fungus, shiitake mushrooms, and black sesame seeds.
Three: Combine Whole Grains and Refined Grains. About one-third of your daily staple foods should be coarse grains such as oats, corn, buckwheat, and whole wheat bread. Rice and wheat should not be too refined, otherwise, most of the vitamins, minerals, and dietary fiber in the grain's outer layer will be lost in the bran and germ.
Four: Ensure Adequate Legume Intake. Those who primarily eat a vegetarian diet must ensure sufficient legume intake. Legumes refer to soybeans, black beans, and green beans. They are rich in high-quality protein, unsaturated fatty acids, calcium, and vitamins B1 and niacin. Their protein content can reach 35%-40%, making them the plant-based food with the highest protein content. They are also rich in lysine, and when consumed with grains, they can effectively complement each other's protein, providing high nutritional value.
Five: A Handful of Nuts Daily. For those on a completely vegan diet, fat intake may be insufficient. Eating a handful of nuts daily, such as hazelnuts, walnuts, almonds, and black sesame seeds, can not only compensate for the lack of fat but also help supplement zinc. However, avoid excessive consumption.
Long-term vegetarians should pay close attention to their intake of calcium, iron, zinc, Vitamin D, and Vitamin B12. It is advisable to moderately supplement with multivitamin formulas, especially those containing iron, zinc, Vitamin D, and Vitamin B12, to prevent potential nutrient deficiencies.
A balanced diet is key to health. From a nutritional perspective, a diet "primarily vegetarian with small amounts of meat, eggs, and dairy" remains the best choice for most people. Avoid blindly following the trend of vegetarianism, especially for individuals with special nutritional needs such as infants, children and adolescents, pregnant women, postpartum and breastfeeding mothers, those with a weak constitution, the elderly, and menopausal women. Otherwise, it will not only be detrimental to health but can actually harm it.
