Vegan Diet Basics: What's On The Standard Menu?

A vegan diet is one that consists of only plant-based foods, including fruits, vegetables, grains, nuts, and legumes. Vegans do not consume any animal products, such as meat, dairy, eggs, or honey. Some people choose to follow a vegan diet for ethical reasons, as they believe that all creatures have a right to life and freedom. Others opt for a vegan diet for its potential health benefits, including lower cholesterol, improved blood glucose, and better blood pressure. Additionally, a vegan diet is more environmentally friendly, as animal agriculture heavily contributes to greenhouse gas emissions. However, it is important to ensure adequate intake of certain nutrients like vitamin B12, calcium, iron, and omega-3 fatty acids when following a vegan diet.

Nutrient deficiencies

A vegan diet is a plant-based diet that excludes all animal products, including meat, eggs, and dairy. While a vegan diet can be very nutritious, it may also put you at risk of certain nutrient deficiencies.

Vitamin B12

Vitamin B12 is generally found in animal foods, and a deficiency can cause unexpected weight loss, tingling in the hands and feet, difficulties remembering information, and soreness of the mouth and tongue. It can also lead to megaloblastic anaemia, which involves the bone marrow producing oversized, undeveloped red blood cells, resulting in low red blood cell levels.

Omega-3 Fatty Acids

Omega-3 fatty acids are crucial for maintaining heart and brain health, and a deficiency can cause swollen, itchy rashes or scaly, dry patches on the skin. Plant-based sources of omega-3 include nuts, seeds, plant oils, and fortified foods, but the conversion rate of ALA to DHA and EPA is very low.

Iodine

Iodine is not produced by the body and must be obtained from the diet. Iodine deficiency can lead to hypothyroidism, which is characterised by an inability to tolerate colder temperatures, among other symptoms. Seaweed or iodised salt can be added to the diet to increase iodine intake.

Iron

Iron is a mineral that helps blood cells carry oxygen and supports brain health. A deficiency may cause anaemia, difficulty concentrating or remembering, and increased susceptibility to infections. Plant-based sources of iron include dried fruits, iron-fortified cereals, and beans.

Vitamin D

Vitamin D is produced by the body through sun exposure, and only a few foods naturally contain it. A vitamin D deficiency is common and can be addressed by taking supplements or consuming fortified foods and mushrooms.

Calcium

Calcium is important for bone health and muscle function, and a deficiency can increase the risk of osteoporosis and bone fractures. Calcium-fortified plant milk and yoghurt, as well as certain green leafy vegetables, are good plant-based sources of calcium.

Zinc

Zinc is important for growth and development, immune function, and protein synthesis. A zinc deficiency can cause hair loss, diarrhoea, and delayed wound healing. Plant-based sources of zinc include whole grains, nuts, seeds, and legumes.

Protein

Protein is essential for growth, repair, and maintenance of the body, and a deficiency can lead to muscle wasting and reduced immune function. Legumes, nuts, seeds, and soy products are good plant-based sources of protein.

Creatine

Creatine is found in animal tissues and helps produce energy during exercise. While creatine is not an essential nutrient, it can improve athletic performance, and vegans may wish to take a synthetic creatine supplement.

Weight loss

A vegan diet is a type of vegetarian diet that eliminates meat, fish, eggs, and dairy products. While some people choose veganism for ethical reasons, the diet is also associated with several health benefits, including weight loss.

Research suggests that a vegan diet may aid weight loss, with some studies indicating that vegans tend to have a lower body mass index (BMI) than non-vegans. A 2016 study found that participants on a vegan diet lost more weight over six months than those on vegetarian, semi-vegetarian, and omnivorous diets, while also reducing their saturated fat intake.

• Calorie Density: Understanding calorie density is crucial. Focus on consuming low-calorie density foods that are naturally part of a whole-food, plant-based diet. These include fruits, vegetables, starchy vegetables, intact whole grains, and legumes. By choosing such foods, you can eat larger volumes while taking in fewer calories.
• Non-starchy Vegetables: Make non-starchy vegetables like kale, cabbage, spinach, and lettuce about 50% of your meals. These foods are low in calorie density, filling you up without adding excessive calories.
• Liquid Calories: Avoid consuming liquid calories in the form of sports drinks, sodas, sweetened beverages, and alcohol. Opt for water instead, as it is calorie-free and hydrating.
• Fiber-Rich Foods: Adopt a lower-calorie, high-fiber, nutrient-rich diet by incorporating more whole, plant-based foods. Include fruits, vegetables, whole grains, and legumes in your meals to increase your fiber intake.
• Vegan Junk Foods: Avoid highly processed vegan foods, such as vegan burgers, sugar-sweetened snacks, and plant-based meat and cheese substitutes. These tend to be dense in calories and low in nutrients.
• Exercise: Incorporate physical activities you enjoy into your routine. Aim for a combination of strength, endurance, balance, and flexibility exercises. Even a short walk each day can be beneficial if your time is limited.

While a vegan diet can be effective for weight loss, it is important to ensure proper nutrition. A well-planned vegan diet should include sufficient protein, vitamins, and minerals to support overall health and weight loss goals.

Health benefits

A vegan diet is a plant-based diet that excludes all animal products, including meat, dairy, and eggs. Vegans also tend to avoid clothes, soaps, and other products that use or contain animal parts, such as leather and animal fur.

There are several health benefits associated with a vegan diet:

Weight Loss

Several studies have shown that a vegan diet can be effective for weight loss. Vegans tend to have lower body mass indexes (BMIs) than non-vegans, and a vegan diet can help reduce the number of calories consumed without actively restricting food intake.

Improved Blood Sugar Control and Lower Risk of Type 2 Diabetes

Adopting a vegan diet may help keep blood sugar levels in check and lower the risk of developing type 2 diabetes. Several studies indicate that vegans benefit from lower blood sugar levels and higher insulin sensitivity, with one study reporting a 78% lower risk of developing type 2 diabetes in vegans compared to non-vegans.

Heart Health

A vegan diet has been linked to a reduced risk of developing high blood pressure and dying from heart disease. Observational studies suggest that vegans may have up to a 75% lower risk of high blood pressure and a 42% lower risk of dying from heart disease.

Cancer Risk Reduction

A vegan diet has been associated with a lower risk of developing or dying from cancer. Vegans tend to consume more legumes, fruits, and vegetables, which are rich in fiber, vitamins, and phytochemicals that offer protection against cancer.

Improved Kidney Function

A vegan diet may help improve kidney function, especially for people with diabetes. Substituting plant protein for meat has been linked to a reduced risk of poor kidney function.

Alzheimer's Disease Prevention

Aspects of the vegan diet, such as increased consumption of fresh fruits and vegetables, may help reduce the risk of developing Alzheimer's disease.

Arthritis Relief

A vegan diet has been found to reduce symptoms of arthritis, including pain, joint swelling, and morning stiffness. The higher antioxidant, probiotic, and fiber content, as well as the elimination of certain trigger foods, could be responsible for these benefits.

While a vegan diet offers numerous health benefits, it is important to note that proper planning is essential. Poorly planned vegan diets may lead to deficiencies in certain nutrients, such as vitamin B12, vitamin D, calcium, and iron. Including a variety of whole plant foods and fortified foods in the diet can help ensure adequate nutrient intake.

Vegan sources of calcium and vitamin D

A vegan diet is a plant-based diet that includes fruits, vegetables, beans, grains, nuts, and seeds. Vegans do not consume any animal products, including meat, dairy, eggs, and honey.

Vegan diets can be very nutritious, but they may be low in certain nutrients like calcium and vitamin D. Here are some vegan sources of calcium and vitamin D:

Vegan Sources of Calcium:

• Green leafy vegetables like broccoli, cabbage, and okra
• Fortified unsweetened soya, pea, and oat drinks
• Sesame seeds and tahini
• Bread (in the UK, calcium is added to white and brown flour by law)
• Dried fruit, such as raisins, prunes, figs, and dried apricots
• Beans, peas, and lentils
• Nuts, especially almonds
• Seaweed, like wakame and kelp
• Fortified foods, such as plant yogurts, cereals, and some baked goods
• Blackstrap molasses

Vegan Sources of Vitamin D:

• Sunlight exposure, especially from late March/early April to the end of September
• Fortified foods, such as breakfast cereals, fat spreads, and unsweetened soya drinks
• Vitamin D supplements (ensure they are vegan-friendly)
• Mushrooms exposed to ultraviolet light during growth
• Fortified orange juice
• Fortified plant-based milk, such as almond milk, soy milk, and rice milk

It is important for vegans to include a variety of these foods in their diet to ensure they are getting enough calcium and vitamin D.

Vegan sources of iron

A vegan diet is a plant-based diet that excludes all animal products, including meat, eggs, and dairy. It is often adopted for ethical, health, or environmental reasons.

Now, onto the topic of iron. Iron is an essential mineral for proper growth and development, and it is used by the body to make hemoglobin and certain hormones. Vegans can obtain non-heme iron (plant-derived) from various sources, and here are some of them:

Fortified Breads and Cereals

Fortified foods are often enriched with essential vitamins and minerals, including iron. Fortified breads and cereals can be a good source of iron for vegans.

Soybeans and Soy-Based Products

Soybeans and soy-based products like tofu and tempeh are not only versatile and nutritious but also excellent sources of iron. Half a cup of tofu contains 6.6 milligrams of iron, while a cup of tempeh provides 4.5 milligrams.

Dark Leafy Greens

Dark leafy greens, such as spinach and Swiss chard, are nutrient-dense foods that offer a good amount of iron. One cup of cooked spinach provides 6.4 milligrams of iron, and the same amount of cooked Swiss chard contains 4 milligrams.

Beans

Beans are a staple in vegan diets and for a good reason. They are an excellent source of plant-based protein and iron. Kidney beans, soybeans, and lima beans have the highest iron content among the bean family.

Nuts and Seeds

Nuts and seeds are not only delicious but also packed with essential nutrients. Some of the best options for iron include pumpkin seeds, hemp seeds, chia seeds, and cashews.

It is worth noting that while a well-planned vegan diet can provide sufficient iron, some factors can hinder its absorption. Tea, coffee, and phytates found in certain plant foods can reduce iron absorption. On the other hand, vitamin C enhances iron absorption, so pairing iron-rich foods with vitamin C-rich foods can be beneficial.
