Vegan Diets: Aging Faster Or Slower?

There is a common misconception that removing animal products from your diet will make you age faster, perhaps due to a perceived lack of protein or omega-3 fats from fish. However, a well-planned vegan diet can be protective against premature ageing.

Vegan diets are often rich in nutrient-dense foods such as fruits, vegetables, legumes, whole grains, nuts, and seeds. These plant-based foods are packed with antioxidants and anti-inflammatory compounds, which play a crucial role in preventing the development of chronic illnesses and age-related diseases like Parkinson's and Alzheimer's.

Research suggests that a vegan diet can promote better health in the long term, decrease wrinkles, and even slightly increase longevity. However, it's important to note that a vegan diet won't stop you from ageing completely. Cellular damage occurs naturally as we age, but a vegan diet can help slow and stabilise this process.

Additionally, it's worth mentioning that the benefits of a vegan diet depend on the specific foods chosen. A vegan diet high in processed foods, sugar, and refined carbohydrates may not provide the same anti-ageing benefits as a whole food, plant-based diet rich in antioxidants and fibre.

In conclusion, while a vegan diet won't make you age faster, a well-planned and balanced vegan diet that includes a variety of nutrient-dense foods may help support healthy ageing and potentially slow down the process.

High blood sugar and type 2 diabetes

It is a common misconception that a vegan diet will make you age faster, perhaps due to the perceived lack of protein or omega 3 fats from fish. However, this is not necessarily true. While ageing is inevitable, the choices we make each day have a real impact on delaying the ageing process and protecting us from its effects.

A well-planned vegan diet can be protective against premature ageing. Plant foods have a beneficial influence on the main processes that promote ageing; oxidation, inflammation and glycation. Plant foods are protective through their antioxidant and fibre content, as well as reduced advanced glycation end products (AGEs) content. AGEs are formed when sugar molecules bond to protein, lipids or nucleic acids in our body, and they play a role in skin ageing through their impact on collagen and elastin fibres that provide the structural framework, elasticity, and resilience of the skin.

A vegan diet is typically higher in antioxidants and anti-inflammatory compounds, which can help to prevent the development of chronic illnesses. Antioxidants, found mostly in vegetable sources, help prevent cell damage caused by free radicals, which can lead to further inflammation and cell damage associated with ageing.

In terms of high blood sugar and type 2 diabetes, a vegan diet can be beneficial in managing blood sugar levels and insulin sensitivity. Research has shown that a vegan diet may help improve blood sugar levels and reduce the need for insulin injections. A vegan diet is also typically lower in fat and calories, which can aid in weight management. Losing weight can help improve insulin sensitivity, as type 2 diabetes is characterised by insulin resistance.

However, it is important to note that a poorly planned vegan diet may also contribute to high blood sugar and type 2 diabetes. A vegan diet that is high in processed foods, sugar, and refined carbohydrates can lead to blood sugar spikes and increase the risk of type 2 diabetes. It is crucial to focus on whole, plant-based foods and maintain a balanced diet to manage blood sugar effectively.

Overall, while a vegan diet can be beneficial in managing blood sugar and type 2 diabetes, it is important to prioritise a well-planned and balanced diet to prevent potential negative consequences.

Lack of B12

A well-planned vegan diet can be protective against premature ageing. However, it is important to ensure that it is well-balanced and includes B12 supplements, as vitamin B12 is essential for maintaining the nervous system, DNA, red blood cell formation, glucose metabolism, regulating new cell growth, and aiding in cognition.

Vitamin B12 is found in animal products, and vegans are at risk of B12 deficiency, which can have serious health consequences. B12 supplements are, therefore, necessary for vegans at any life stage.

Some of the serious health consequences of B12 deficiency include:

• Nerve damage causing tingling in the hands and feet
• Anaemia, resulting in fatigue, weakness and lightheadedness
• Mouth ulcers, a sore tongue and loss of appetite
• Vision problems such as blurred vision
• Mental health issues like depression, memory loss and behavioural changes
• A higher risk of heart disease, as B12 helps prevent a build-up of homocysteine, which can lead to atherosclerosis
• Infertility, as B12 plays a role in ovulation and sperm production
• Bone and tooth health issues, as B12 is important for bone formation and tooth development
• Developmental delays in children, as B12 is crucial for brain development

High cholesterol

A vegan diet is typically low in cholesterol, as it does not include animal products. However, vegans can still experience high cholesterol due to various factors, such as:

Diet Quality

A vegan diet that includes a lot of fried and processed foods high in saturated and trans fats can increase low-density lipoprotein (LDL) or "bad" cholesterol levels. Some vegan cheeses and desserts are made with coconut oil, palm oil, or partially hydrogenated oils, which are known to increase cholesterol. Refined carbohydrates and sugars can also lead to elevated cholesterol levels.

Genetic Factors

Some individuals have a genetic predisposition called familial hypercholesterolemia, which affects how the body processes cholesterol, resulting in high LDL cholesterol levels regardless of dietary habits.

Physical Inactivity

Even with a vegan diet, a sedentary lifestyle can negatively affect cholesterol levels. Regular exercise can help increase high-density lipoprotein (HDL) or "good" cholesterol, which aids in removing cholesterol from the bloodstream and promotes heart health.

Other Health Conditions

Underlying health conditions such as hypothyroidism and chronic kidney disease may disrupt the normal balance and processing of blood lipids, leading to high cholesterol levels.

To maintain healthy cholesterol levels, it is crucial to eat a nutritious diet rich in whole foods, fruits, vegetables, whole grains, legumes, nuts, and seeds, while reducing the consumption of processed foods high in saturated and trans fats, sugars, and sodium. It is also important to engage in regular physical activity and avoid tobacco and excessive alcohol consumption.

Malnutrition

• Vitamin B12 Deficiency: Vitamin B12 is predominantly found in animal-based foods, and vegans are at a higher risk of deficiency. According to studies, 92% of vegans experience vitamin B12 deficiencies, which can lead to anaemia, fatigue, and an increased risk of coronary artery disease. Untreated, vitamin B12 deficiency can cause irreversible nerve damage.
• Calcium Deficiency: Vegans who exclude dairy products may not get sufficient calcium, which is essential for bone health. This can result in osteoporosis and an increased risk of bone fractures.
• Omega-3 Fatty Acids: These are primarily found in fish and some types of grains, such as flaxseed or linseed. A deficiency in omega-3s can disrupt the balance in the body, making individuals more susceptible to diseases.
• Iron Deficiency: While iron can be obtained from leafy vegetables, the absorption of iron from plant sources is less efficient. Iron is crucial for producing red blood cells, and women of reproductive age are particularly vulnerable to iron deficiencies.
• Vitamin D Deficiency: Vitamin D can be obtained from sunlight and certain foods like milk, eggs, and fish. Vegans may struggle to obtain sufficient vitamin D, which can impact their overall health.
• Protein Deficiency: Vegans may struggle to consume enough high-quality protein, which is essential for muscle function and hormone production.
• Micronutrient Deficiencies: Vegans may also experience deficiencies in other micronutrients such as iodine, zinc, and magnesium.

It is important to note that these deficiencies can be prevented or managed through careful dietary planning and, in some cases, supplementation. A well-planned vegan diet that includes a variety of plant-based sources of essential nutrients can be healthy and nutritionally adequate. However, the risk of malnutrition should be carefully considered, especially for those following a vegan diet long-term.

Inflammation

Diet plays a crucial role in inflammation. The gastrointestinal tract houses more than half of our immune defences, monitoring the foods we eat. Certain foods can trigger inflammation and initiate a chronic response if consumed repeatedly, while other foods have anti-inflammatory properties.

Meat, for instance, has been linked to increased inflammation and premature ageing. Meat consumption can elevate C-reactive protein (CRP) levels, which are predictive of serious illnesses, including cardiovascular disease. Additionally, meat induces insulin resistance and raises insulin-like Growth Factor 1 (IGF-1) levels, which is linked to a higher risk of certain cancers.

On the other hand, a vegan diet has been associated with reduced inflammation and slower biological ageing. A study involving identical twins found that those on a vegan diet exhibited lower biological age, weight loss, and improved cholesterol levels compared to their omnivorous counterparts. Research has also shown that vegans who consume high quantities of fruits and vegetables tend to have lower inflammatory markers than meat-eaters.

The anti-inflammatory properties of a vegan diet can be attributed to the abundance of antioxidants and nutrients found in plant-based foods. Colourful fruits and vegetables, especially dark green leafy veggies, berries, garlic, and onions, are rich in antioxidants that help neutralise free radicals in the body.

While a vegan diet can offer anti-inflammatory benefits, it is important to note that not all vegan diets are inherently healthy. A well-planned vegan diet that focuses on whole, nutrient-dense foods is key to reaping the maximum benefits of this lifestyle.
