Vegan Diets: Healthy Or A Highway To Obesity?

A vegan diet is based on plants and foods made from plants, including vegetables, grains, nuts, and fruits. Vegans do not eat foods that come from animals, including meat, dairy products, and eggs.

A vegan diet can be high in calories and fat, with foods such as nuts, nut butters, avocados, quinoa, and olive oil being calorie-dense and containing healthy fats. However, it is possible to follow a low-fat vegan diet, and some people use vegan diets specifically to lose weight.

A well-planned vegan diet can provide all the nutrients required for a healthy body, but without careful planning, a vegan diet may lack essential nutrients such as calcium, iron, vitamin B12, iodine, and selenium.

High-calorie foods for weight gain

A vegan diet is based on plants and foods made from plants, including vegetables, grains, nuts, and fruits. Vegans do not eat foods that come from animals, such as meat, poultry, fish, dairy products, and eggs.

A well-planned vegan diet can provide all the nutrients you need, but it is important to be mindful of certain nutrients that are more difficult to obtain through a vegan diet, such as calcium, iron, vitamin B12, iodine, and selenium.

• Nuts and Nut Butters: Nuts are an excellent source of protein, healthy fats, and calories. Walnuts, almonds, cashews, and pecans are great choices. Nut butters are also high in calories and can be added to snacks, smoothies, or sides.
• Avocados: Avocados are rich in heart-healthy fats, fiber, and various micronutrients. They provide about 322 calories per fruit and can be added to smoothies, spread on toast, or cubed on salads.
• Quinoa: Quinoa is a pseudo-grain that is high in protein, fiber, and various nutrients. It provides about 222 calories per cooked cup and is one of the few complete plant-based sources of protein.
• Tahini: Tahini is a staple in Mediterranean and Middle Eastern cuisines made from toasted and ground sesame seeds. It is high in protein, fiber, healthy fats, and calories, with approximately 89 calories per tablespoon. It can be used as a spread, dip, or dressing.
• Olive Oil: Rich in healthy monounsaturated fats, olive oil has various health benefits. It is also high in calories, with 119 calories and 13.5 grams of fat per tablespoon. It can be drizzled over cooked vegetables, added to salad dressings, or used in marinades.
• Dried Fruit: Dried fruit is a good source of extra calories, vitamins, minerals, and antioxidants. The calorie content varies depending on the type of fruit. For example, prunes have 209 calories per half cup, while raisins have 247 calories. It is best to combine dried fruit with a source of protein to minimize the impact of its high sugar content.
• Legumes: Legumes, such as lentils, beans, and chickpeas, are high in protein, fiber, and calories. For example, one cup of cooked black beans provides 227 calories, along with 15 grams of protein and fiber. Legumes are also a good source of vitamins and minerals.
• Sweet Potatoes: Sweet potatoes are a starchy vegetable that is high in calories, fiber, and essential vitamins, minerals, and antioxidants. One cup of cooked sweet potato contains about 180 calories. They can be prepared in various ways, such as roasting, baking, mashing, or grilling.
• Vegan Smoothies: Smoothies are a quick and convenient way to consume a concentrated dose of calories. Using a vegan protein powder or soy yogurt can maximize the potential health benefits. Adding ingredients like nut butter, dried or fresh fruits, avocados, almond milk, coconut oil, and seeds can make smoothies more nutritious and calorie-dense.
• Rice: Rice is a cost-effective, versatile, and calorie-dense carbohydrate. It provides a bit of protein and fiber, along with important vitamins and minerals. One cup of cooked brown rice provides 216 calories. It can be combined with a source of protein for a balanced meal or snack.
• Coconut Oil: Coconut oil is rich in calories and has been associated with various health benefits. It is easy to use and can be swapped for other fats and oils in cooking. A single tablespoon of coconut oil contains 116 calories and 13.5 grams of fat.

Vegan diets and vitamin B12 deficiency

A vegan diet is based on plants, including vegetables, grains, nuts, and fruits, and foods made from plants. Vegans do not eat foods that come from animals, including meat, fish, dairy products, and eggs.

A well-planned vegan diet can provide all the nutrients you need, but it is important to be aware of the risk of vitamin B12 deficiency. Vitamin B12 is found in animal products, so vegans may need to include fortified foods or supplements in their diet to ensure they are getting enough.

Vitamin B12 is essential for maintaining healthy blood and a healthy nervous system. A lack of vitamin B12 has been linked to neurologic and hematologic problems, and it can also increase the risk of certain cancers. Vegans who do not include vitamin B12-rich foods in their diet may need to take a supplement to prevent deficiency.

Some vegan sources of vitamin B12 include:

• Breakfast cereals fortified with B12
• Unsweetened soya drinks fortified with vitamin B12
• Yeast extract, such as Marmite, and nutritional yeast flakes

In addition to vitamin B12, vegans may also need to include sources of calcium, vitamin D, iron, omega-3 fatty acids, and zinc in their diet, as these nutrients can be more difficult to obtain from plant-based sources.

Overall, a vegan diet can be healthy and provide all the necessary nutrients, but it is important to be mindful of potential deficiencies and include a variety of fortified foods or supplements as needed.

Vegan diets and mental health

Vegan diets are not fattening and can be beneficial for weight loss. Research has shown that a vegan diet may be associated with improved health outcomes, including a reduced risk of cardiometabolic diseases such as cardiovascular disease, type 2 diabetes, obesity, and non-alcoholic fatty liver disease.

However, it is important to note that vegan diets can also be associated with adverse health outcomes if not properly planned. For example, vegans may be at risk of vitamin B12 deficiency, which has been linked to neurologic and haematologic problems, as well as an increased risk of certain cancers. Vegans may also have greater iron and zinc needs, and it can be challenging to obtain sufficient amounts of these minerals from plant-based sources due to issues with bioavailability and absorption.

In terms of mental health, there is conflicting evidence. Some research suggests that vegan diets may be linked to a higher prevalence of mental health problems and a poorer quality of life, with an increased risk of unipolar depressive and anxiety disorders. However, other studies indicate that a vegan diet can improve mental health by reducing inflammation linked to diseases like type 2 diabetes, heart disease, and cancer.

Overall, a well-planned vegan diet that includes a variety of fortified foods and supplements can provide all the necessary nutrients to support both physical and mental health.

Vegan diets and calcium intake

A vegan diet can be high in fat, depending on the types of food chosen. For example, nuts, seeds, avocados, and coconut oil are all vegan foods that are high in fat.

However, it is important to note that plant-based fats are generally considered healthier than animal-based fats. Additionally, a vegan diet can be low in fat if desired, as there are many vegan food options that are low in fat, such as stir-fries cooked with water instead of oil.

Ultimately, the decision to include or exclude high-fat foods in a vegan diet is a personal one, and there is no one-size-fits-all approach. Some people may choose to follow a high-fat vegan diet, while others may prefer a low-fat or moderate-fat vegan diet.

It is worth noting that a well-planned vegan diet can provide all the nutrients required for a healthy body, including calcium.

Calcium is essential for maintaining healthy bones and teeth. While non-vegans get most of their calcium from dairy products, vegans can obtain it from other sources, such as:

• Green, leafy vegetables like broccoli, cabbage, and okra (but not spinach, as the body cannot digest all the calcium in spinach)
• Fortified unsweetened soya, pea, and oat drinks
• Sesame seeds and tahini
• Bread (in some countries, calcium is added to flour by law)
• Dried fruit, including raisins, prunes, figs, and dried apricots

It is important for vegans to ensure they are getting enough calcium, as a deficiency can lead to bone and teeth health issues. Including a variety of calcium-rich plant-based foods in the diet can help maintain adequate calcium intake.

Vegan diets and physical activity

A vegan diet, based on plants, can be a healthy choice, but it requires careful planning to ensure all essential nutrients are included. A vegan diet can be high in healthy fats and calories, which may support weight gain for those who need it. However, it is important to note that plant-based diets tend to be lower in unhealthy saturated fats and cholesterol.

Weight Gain on a Vegan Diet

For those looking to gain weight, a vegan diet can still be a viable option. Nuts and nut butters, for example, are excellent sources of protein, healthy fats, and calories. A daily handful of nuts or a couple of tablespoons of nut butter can easily be added to snacks, sides, or smoothies to increase calorie intake. Avocados, another vegan staple, provide healthy fats and fibre, with one avocado containing approximately 322 calories.

Other high-calorie vegan foods include quinoa, tahini, olive oil, dried fruit, legumes, sweet potatoes, and vegan smoothies. These foods can be incorporated into meals and snacks to boost calorie consumption and promote weight gain.

Physical Activity and a Vegan Diet

A well-planned vegan diet can provide all the nutrients needed to support an active lifestyle. It is important for highly active individuals to ensure adequate protein intake, which can be achieved through plant-based protein sources or supplements.

Vegan diets are often associated with a healthier lifestyle, including more physical exercise. This correlation may be due to vegans' tendency to have better socioeconomic levels and make healthier lifestyle choices, such as avoiding tobacco products.

Overall Health Benefits of a Vegan Diet

A vegan diet has been linked to a reduced risk of cardiometabolic diseases, including cardiovascular disease, type 2 diabetes, obesity, and non-alcoholic fatty liver disease. Plant-based diets are typically rich in fibre, vitamins, minerals, and antioxidants, which help protect against disease.

However, it is important to note that a vegan diet can also lead to micro and macronutrient deficits if not properly planned. For example, vitamin B12 deficiency is common in vegan diets due to the exclusion of meat, poultry, and eggs, and can have serious health consequences. Vegans should ensure they get their vitamin B12 levels checked regularly and consider taking supplements or consuming fortified foods to meet their daily requirements.

Additionally, vegans may have greater iron and zinc needs due to the lower bioavailability of these nutrients in plant-based foods. It is crucial for vegans to be mindful of these potential deficiencies and include a variety of nutrient-rich foods in their diet to maintain optimal health.
