Vegan Diet: The Complete Guide to a 100% Plant-Based Diet

Veganism isn't just about removing animal products: it's about building a rich, varied, and nutritionally complete plant-based diet. With over 400 vegan recipes in its database and an AI adaptation engine, FoodCraft supports you at every step of your transition to a 100% plant-based diet. This guide gives you the keys to successfully switching to veganism without deficiencies or frustration.

Steps

1

Evaluate your current diet

Before changing your habits, take stock of what you already eat. Identify which animal products to replace and which plant-based foods you already consume regularly. FoodCraft can analyze your nutritional profile and identify necessary adjustments through its AI coach.

2

Learn the basics of plant-based nutrition

Familiarize yourself with plant sources of protein (legumes, tofu, tempeh, seitan), iron (lentils, spinach, pumpkin seeds), calcium (broccoli, kale, fortified plant milk), and omega-3s (flaxseeds, chia seeds, walnuts). Variety is your best ally.

3

Plan your meals gradually

Don't go 100% plant-based overnight. Start by veganizing one meal a day, then gradually increase. FoodCraft's AI planning generates balanced vegan menus over 7 days, tailored to your tastes and calorie needs.

4

Secure your intake of critical nutrients

Vitamin B12 must be supplemented—there is no reliable plant source. Plan for a B12 supplement (cyanocobalamin, 1000 µg two to three times a week or 25 µg daily). For vitamin D, winter supplementation is recommended.

5

Build a repertoire of vegan recipes

Explore FoodCraft's 400+ vegan recipes: chickpea curries, quinoa bowls, vegetable lasagnas, cashew-based desserts. Use Spark Vision to photograph a dish that inspires you and get a vegan version tailored to your profile.

6

Monitor and adjust your intake

After a few weeks, verify that your diet covers your needs. An annual blood test (B12, iron, vitamin D, zinc) is recommended. FoodCraft automatically calculates the nutritional intake of each meal to help you spot any imbalances.

Nutritional principles of veganism

A well-planned vegan diet is recognized by the Academy of Nutrition and Dietetics as nutritionally adequate for all stages of life. The key lies in dietary diversity. Combine whole grains and legumes to get all the essential amino acids. Include colorful fruits and vegetables daily for antioxidants, nuts and seeds for essential fatty acids, and fortified foods (plant milks, nutritional yeast) to round out your intake. A vegan diet naturally offers a wealth of fiber, vitamin C, and protective phytonutrients.

Critical nutrients to monitor

Five nutrients deserve special attention in a vegan diet. Vitamin B12 is the only truly indispensable supplement: no plant source provides it in reliable amounts. Non-heme iron from plants is absorbed less efficiently, but you can improve absorption by combining meals with foods rich in vitamin C. Long-chain omega-3s (EPA and DHA) are found in microalgae—consider an algae oil supplement. Zinc is found in pumpkin seeds, cashews, and legumes. Finally, calcium is available in kale, broccoli, almonds, and fortified plant milks.

Building complete vegan meals

A balanced vegan meal follows the four-pillar rule: a protein source (legumes, tofu, tempeh), whole grains (brown rice, quinoa, buckwheat), varied vegetables (at least two different colors), and a source of healthy fats (avocado, nuts, olive oil). For example: a bowl of red lentil curry with brown rice, sautéed spinach, and sesame seeds. FoodCraft automatically composes meals following this structure using its AI planning algorithm, ensuring each day hits your macro and micronutrient goals.

FoodCraft Tip

Over 400 vegan recipes in FoodCraft

The FoodCraft database contains over 400 certified vegan recipes, from appetizers to desserts. Each recipe displays its full nutritional profile: protein, iron, calcium, zinc, and B12. You can filter by prep time, difficulty, or ingredients available in your pantry.

AI Adaptation: turn any recipe into a vegan version

Thanks to FoodCraft's AI adaptation, you can convert any of the 3,200+ recipes into a vegan version. The algorithm intelligently replaces animal ingredients with nutritionally equivalent plant alternatives, preserving the flavors and textures of the original dish.

Frequently Asked Questions

Does a vegan diet provide enough protein?
Yes, provided you vary your sources. Legumes (lentils, chickpeas, beans), soy (tofu, tempeh, edamame), seitan, nuts, and seeds provide plenty of protein. An adult needs about 0.8 g of protein per kg of body weight, a goal easily achievable with a diverse plant-based diet. FoodCraft automatically checks that your menus hit your protein targets.
Is a B12 supplement really necessary?
Absolutely. Vitamin B12 is produced by bacteria and is not present in sufficient amounts in unfortified plant foods. A B12 deficiency can lead to anemia and neurological disorders. Take a 1,000 µg cyanocobalamin supplement two to three times a week, or consume fortified foods (plant milk, nutritional yeast) daily.
Is a vegan diet suitable for children and pregnant women?
Leading dietetic associations consider a well-planned vegan diet to be suitable for all ages, including during pregnancy and childhood. However, increased medical and nutritional monitoring is recommended, with special attention to B12, iron, calcium, omega-3s, and iodine. Consult a healthcare professional for personalized support.
How to replace eggs in vegan cooking?
Several alternatives exist depending on the use. For baking: applesauce (75 g per egg), ground flaxseeds (1 tablespoon + 3 tablespoons water), mashed banana, or aquafaba (chickpea brine). For omelets: seasoned silken tofu with black salt (kala namak) remarkably replicates the taste of eggs. FoodCraft automatically adapts recipes by suggesting the most suitable substitute.
Is a vegan diet more expensive?
Not necessarily. The basics of a vegan diet—dried legumes, whole grains, seasonal vegetables, tofu—are among the cheapest foods on the market. It's the processed 'vegan' products (plant-based cheeses, meat alternatives) that increase the budget. FoodCraft helps you plan economical vegan menus by prioritizing basic ingredients and seasonal produce.
