Final answer:
A basic vegan diet should be modified to include a greater variety of fruits and vegetables. Avoid processed foods, and use unsaturated oils. Combining different plant foods for complete proteins and limiting sugar and salt intake are also important for a balanced vegan diet.
Step-by-step explanation:
A basic vegan diet should be modified to include more of option 1) Fruits and vegetables. It is important for vegans to choose a variety of different vegetables each day, including both dark green vegetables like spinach and broccoli, and orange vegetables like carrots and sweet potatoes. As much as possible, opt for fresh fruits rather than canned, and whole fruits over fruit juices for additional fiber.
When it comes to oils, it's best to select unsaturated oils such as olive oil, canola oil, or vegetable oil. It is also crucial to focus on whole foods rather than processed foods, aiming to consume more plant foods and fewer animal foods. Vegans should be particularly mindful of combining plant foods to create complete proteins, such as pairing beans with rice to ensure they are getting all nine essential amino acids.
Likewise, limiting intake of sugar and salt is important, with an emphasis on avoiding processed foods, which tend to have higher levels of these. Instead, vegans should strive for a diet rich in whole grains, legumes, nuts, and a colorful variety of fruits and vegetables to ensure a well-rounded intake of nutrients.
