Vegan Diet: Strategies For Success And Healthy Eating

Veganism is a way of living that seeks to exclude all forms of animal exploitation and cruelty, whether for food, clothing, or any other purpose. A vegan diet is based on plants and foods made from plants, including fruits, vegetables, beans, grains, nuts, and seeds. People who follow a vegan diet don't eat any animal products, including meat, dairy, eggs, and honey.

There are several types of vegan diets, including the whole food vegan diet, the raw food vegan diet, and the 80/10/10 diet. A well-planned vegan diet can provide all the nutrients needed to maintain a healthy body. However, it is important to be aware of the potential risks of nutrient deficiencies, especially vitamin B12, vitamin D, omega-3s, iodine, iron, calcium, and zinc.

Veganism has gained popularity in recent years, with people choosing to adopt this lifestyle for ethical, environmental, or health reasons. It is important to note that veganism is not just about diet; vegans also avoid using animal-derived materials and products tested on animals.

How to get the right nutrients from a vegan diet

A vegan diet can be very healthy, but it may require careful planning to ensure you get all the nutrients your body needs. Here are some tips to help you get the right nutrients from a vegan diet:

Eat a Variety of Whole Foods

Eat a variety of whole plant-based foods, including fruits, vegetables, whole grains, legumes, nuts, and seeds. These foods provide essential vitamins, minerals, and phytochemicals.

Pay Attention to Protein Sources

Protein is essential for the body, and vegans can get complete proteins from plant-based sources such as legumes (beans, peas, lentils), soy products (tofu, tempeh), whole grains, nuts, and seeds. Include a variety of these in your diet to ensure sufficient protein intake.

Focus on Vitamin B12 Sources

Vitamin B12 is mainly found in animal products, so vegans need to be mindful of including B12-fortified foods such as breakfast cereals, nutritional yeast, and plant-based milk. A B12 supplement may also be necessary.

Ensure Adequate Calcium and Vitamin D Intake

For calcium, include dark leafy greens like broccoli and kale, fortified plant-based milk, and calcium-set tofu in your diet. For vitamin D, aim for regular sun exposure, include fortified foods like plant-based milk and breakfast cereals, and consider taking a supplement during autumn and winter.

Get Enough Iron

Iron is important for red blood cell production, and while it is present in plant-based foods, the body absorbs it less efficiently than iron from meat. Include iron-rich plant sources such as legumes, whole grains, and dark leafy greens, and pair them with vitamin C-rich foods to enhance absorption.

Supplement with Omega-3 Fatty Acids

Omega-3 fatty acids are important for heart and brain health. While the most bioavailable form is found in fish, vegans can get omega-3s from plant sources like chia seeds, flaxseeds, and walnuts. Consider taking an algae-based omega-3 supplement to ensure adequate intake.

Monitor Your Zinc Intake

Zinc is found in meat, shellfish, and dairy, but vegans can obtain it from plant sources like pumpkin seeds, baked beans, fortified cereals, and nuts. Soaking and sprouting beans and grains can also help maximize zinc absorption.

Consider a Multivitamin or Supplement

If you are concerned about meeting all your nutrient requirements, consider taking a vegan multivitamin or specific supplements like B12 and omega-3s. Always check the labels to ensure the supplements are vegan-friendly and free from animal-derived ingredients.

Plan Your Meals

Proper planning is essential to ensure you get a balanced mix of nutrients. Create meal plans that include a variety of nutrient-dense foods and consider working with a registered dietitian to fine-tune your vegan diet.

Vegan sources of calcium and vitamin D

Calcium and vitamin D are essential nutrients for bone health, and vegans can get these nutrients from various plant-based sources. Here are some detailed paragraphs on vegan sources of calcium and vitamin D:

Vegan Sources of Calcium

Vegan diets can be rich in calcium, a mineral that is crucial for bone and teeth health. Some plant-based sources of calcium include calcium-fortified plant milk and orange juice, tofu processed with calcium, tempeh, collard greens, turnip greens, and calcium-fortified soy yogurt. Additionally, certain types of algae, such as spirulina and chlorella, are good sources of calcium.

Some vegan-friendly foods that are naturally rich in calcium include bok choy, kale, mustard greens, watercress, broccoli, and chickpeas. It is important to include a variety of these calcium-rich foods in the diet to ensure adequate intake.

Calcium Absorption and Recommended Intake

To enhance the absorption of calcium, it is beneficial to consume vitamin D and vitamin K alongside calcium-rich foods. Additionally, certain companies offer calcium supplements derived from red algae or Icelandic red algae, which is a natural source of calcium, magnesium, and trace minerals.

The recommended daily intake of calcium for most adults is 1000 mg, increasing to 1200 mg per day for adults over 50 years old. Vegans may have slightly lower calcium requirements due to the absence of meat in their diets, but more scientific research is needed to confirm this.

Vegan Sources of Vitamin D

Vitamin D is essential for maintaining bone health and supporting various bodily functions. While sunlight is a significant source of vitamin D, there are also plant-based dietary sources that vegans can include in their diets.

Fortified foods are a common source of vitamin D for vegans. These include fortified cereals, bread, orange juice, and plant milk. Additionally, vitamin D2 and vegan D3 supplements are available, ensuring that vegans can meet their recommended daily intake.

Vitamin D Requirements

The recommended daily intake of vitamin D for adults is 600-800 IU (15-20 mcg), depending on age. However, these values may vary depending on individual circumstances, and it is always advisable to consult a healthcare professional for personalized recommendations.

In conclusion, a well-planned vegan diet can provide adequate amounts of calcium and vitamin D. By including a variety of plant-based sources in their diets and considering supplements when necessary, vegans can ensure they meet their nutritional requirements for these essential nutrients.

Vegan sources of iron

Iron is a mineral that is essential for proper growth and development. It is used by the body to make hemoglobin and certain hormones. There are two types of iron: heme (animal-derived) and non-heme (plant-derived).

• Dried beans and legumes
• Dark green leafy vegetables (e.g. spinach, swiss chard)
• Dried fruits
• Nuts and seeds
• Wholegrain cereals and breads
• Iron-fortified products (e.g. fortified wheat biscuits)

It is a common misconception that a vegan diet is missing iron. In fact, vegans are no more likely to develop iron deficiency anemia than the general population. This is because a vegan diet is typically high in vitamin C, which improves the absorption of non-heme iron.

Some tips to increase iron absorption include:

• Consuming vitamin C-rich foods at the same time as iron-rich foods
• Avoiding coffee and tea with meals, as these can reduce iron absorption
• Using a cast-iron pan, as a small amount of iron may be transferred to food during cooking

Vegan sources of vitamin B12

Vitamin B12 is crucial for maintaining healthy blood and a healthy nervous system. It is naturally produced by bacteria and found in animal products because animals consume unsanitized food and water. Vegans can still get their B12 fix through supplements and certain foods.

Nutritional Yeast

Nutritional yeast is a common substitute for cheese in plant-based diets. It is often fortified with vitamin B12 and has a rich, nutty, and cheesy flavor. It is a great source of protein, vitamins, minerals, and fiber. It can be sprinkled on popcorn, mixed into sauces, mashed potatoes, or scrambled tofu, or stirred into soups.

Fortified Foods

Fortified foods are the most efficient and reliable source of vitamin B12 for vegans. This includes fortified breakfast cereals, non-dairy milk, and plant-based meats. For example, Kellogg's All-Bran Original breakfast cereal provides 20% of the vitamin B12 requirement in one serving. Similarly, one cup of fortified unsweetened soy milk contains 1mcg, or 42%, of the daily vitamin B12 needs.

Yeast Spreads

Yeast spreads like Marmite and Vegemite are another source of vitamin B12. Marmite contains 1.9mcg of vitamin B12 per serving (8 grams), which equals 76% of the recommended daily intake. Vegemite 40% Less Salt provides 0.5mcg or 25% of the recommended daily intake per serving (5 grams).

Tempeh

Tempeh is a traditional Indonesian food made from fermented soybeans. It is one of the few non-fortified foods in a vegan diet that provides some vitamin B12. Half a cup of tempeh can provide up to 0.1mcg of vitamin B12, or about 3% of the daily requirement. It is also a good source of plant-based protein and gut-friendly bacteria.

Shiitake Mushrooms

Dried shiitake mushrooms are a natural source of vitamin B12. Consuming approximately 50 grams of dried shiitake mushrooms can provide the daily requirement of vitamin B12, which is about 2.4mcg. However, this is a large amount to consume daily, so it should not be relied on as the sole source of B12.

While these foods can provide some vitamin B12, vegans are still at risk of vitamin B12 deficiency. Therefore, it is recommended to supplement with vitamin B12, especially if you do not regularly consume fortified foods.

Vegan sources of omega-3 fatty acids

A vegan diet can be a healthy choice, but it's important to be aware of the potential risks of nutrient deficiencies and plan meals accordingly. Omega-3 fatty acids are one such essential nutrient, offering many health benefits, including reducing inflammation, decreasing blood triglycerides, and reducing the risk of dementia.

Walnuts

Walnuts are a great source of healthy fats and omega-3 fatty acids, with about 65% fat content by weight. They have been linked to improved brain health and cognitive performance in several animal and human studies. Just one ounce of walnuts provides 2,570 mg of omega-3 fatty acids, which is 160-233% of the recommended daily intake.

Chia Seeds

Chia seeds are an excellent source of omega-3s, as well as protein and fibre. They have been found to decrease the risk of chronic diseases when consumed as part of a healthy diet. One ounce of chia seeds provides 5,000 mg of omega-3s, far exceeding the recommended daily intake.

Flaxseed

Flaxseed is a nutritional powerhouse, offering fibre, protein, magnesium, and manganese. It is also an excellent source of omega-3s, with one tablespoon containing 2,350 mg, surpassing the recommended daily amount. Flaxseed can be easily incorporated into baking or added to cereals, oatmeal, soups, or salads.

Hemp Seeds

Hemp seeds are another good source of omega-3s, as well as protein, magnesium, iron, and zinc. Three tablespoons of hemp seeds contain approximately 2,600 mg of omega-3s, or 162-236% of the daily recommended intake. They can be sprinkled on yogurt or blended into smoothies.

Seaweed and Algae

Seaweed, spirulina, nori, and chlorella are all forms of algae that provide one of the few plant-based sources of EPA and DHA omega-3s. They are especially important for vegans and vegetarians to consume. Nori can be used in homemade sushi rolls, while spirulina and chlorella powders can be added to smoothies or pancakes.
