A vegetarian diet can be started at any age, and there are many health benefits associated with it. However, it is important to ensure that it is well-planned, especially for older adults, to ensure that nutritional needs are met. Older adults have different nutritional requirements, and a vegetarian diet may need to be adjusted to cater to these needs. For example, older adults need more protein to preserve lean body mass, body function, and good health. They are also at a higher risk of vitamin B12 deficiency, which can be combated with B12-enriched vegan foods or supplements. A vegetarian diet can be a healthy choice for a 70-year-old as long as it is thoughtfully planned and tailored to their specific needs.

What You'll Learn
Nutritional requirements
A vegetarian diet can meet all a person's nutritional needs if thoughtfully planned. It should include a variety of fruits, vegetables, whole grains, and nuts, while avoiding saturated fats, controlling calories and portions, and being physically active. A vegetarian diet is typically associated with lower rates of heart disease, high blood pressure, diabetes, and cancer. It can also help lower the risk of stroke and other chronic illnesses.
Protein is an important consideration for older adults, who need more protein than the general adult population to preserve lean body mass, body function, and good health. While most adults need around 0.75g of protein per kilogram of body weight per day, it is recommended that healthy older adults increase their daily protein intake to 1.0-1.2g per kilogram of body weight. This can be achieved through plant-based proteins such as chickpeas, tofu, black-eyed beans, kidney beans, lentils, quinoa, wild rice, nuts, seeds, and soy alternatives to milk and yogurt.
Vitamin B12 is another important nutrient to consider, as older adults may be at risk of vitamin B12 deficiency. It is essential for making red blood cells, keeping the nervous system healthy, and providing energy. While meat, fish, and eggs are abundant sources of vitamin B12, plant-based sources include fortified cereals, yeast extracts, soy yogurts, and non-dairy milk.
Calcium and vitamin D are also crucial for maintaining good bone health, especially in older adults due to the risk of osteoporosis and associated fractures. While dairy products are a good source of calcium, plant-based alternatives include calcium-fortified soy milk, almond milk, cereals, and certain types of bread. Vitamin D is difficult to obtain from diet alone, so a supplement of 10mcg per day is recommended, especially during winter or for those who don't get outside often.
In conclusion, a vegetarian diet at 70 can meet nutritional requirements if carefully planned to include a variety of fruits, vegetables, whole grains, and plant-based sources of protein, calcium, and vitamins B12 and D.

Health benefits
A vegetarian diet can offer several health benefits for seniors. Here are some of the key advantages:
Cardiovascular Health
Vegetarian diets are typically low in saturated fat and cholesterol, which are contributing factors to heart disease. A well-balanced vegetarian diet can help reduce cholesterol levels and blood pressure, thereby lowering the chances of strokes, heart attacks, and cardiovascular disease. This is particularly beneficial for seniors, as they are often advised to avoid meat due to its negative impact on cardiovascular health.
Weight Management
Vegetarian diets tend to be lower in calories and saturated fats, making them ideal for weight management. Maintaining a healthy weight is crucial for seniors to prevent chronic diseases, maintain mobility, and reduce the risk of obesity-related conditions such as type 2 diabetes and heart disease. The abundance of fruits, vegetables, legumes, and whole grains in a vegetarian diet provides essential nutrients while aiding in weight control.
Digestive Health
A vegetarian diet is rich in dietary fibre, which promotes regular bowel movements and improves overall digestive health. As people age, they often encounter digestive issues, and the high fibre content in a vegetarian diet can help alleviate these problems. Fibre also helps lower LDL (bad) cholesterol and controls blood sugar and weight.
Cognitive Function and Overall Wellbeing
A vegetarian diet has been linked to improved cognitive function and overall wellbeing in seniors. The abundance of antioxidants in plant-based foods has anti-inflammatory properties, which contribute to better health. Additionally, a vegetarian diet can help reduce the risk of certain cancers, such as colon cancer.
It is important to note that while a vegetarian diet can offer these health benefits, it should be well-planned and tailored to the individual's needs, especially for seniors. Consulting a healthcare professional before making any drastic dietary changes is always recommended.

Risks and deficiencies
A vegetarian diet can be safe and healthy for people over 70, but there are some risks and potential deficiencies to be aware of.
Protein deficiency is a potential issue for older adults considering a vegetarian diet. Animal-based foods are currently the major source of dietary protein for older adults in Western societies, and studies have shown that a high relative contribution of animal-based foods (60% or more) is common in this demographic. While plant-based proteins such as chickpeas, tofu, beans, lentils, and nuts can provide sufficient protein, it is important to ensure that meals and snacks contain these protein sources. This is especially important for older adults, who need more protein than younger adults to preserve lean body mass, maintain body function, and support overall health.
Vitamin B12 deficiency is another concern, as this nutrient is found abundantly in animal-based food sources. Older adults are already at a higher risk of vitamin B12 deficiency, and those following a vegetarian diet may need to be particularly mindful of their B12 intake. Vitamin B12 is essential for making red blood cells, maintaining a healthy nervous system, and providing energy. Plant-based sources of vitamin B12 include fortified cereals, soya yoghurt, and non-dairy milk, but supplements may also be necessary to ensure adequate intake.
Vitamin D deficiency is also a potential risk, as it is difficult to obtain sufficient vitamin D from diet alone. Older adults are recommended to take a vitamin D supplement of 10mcg per day, especially during the winter months when sunlight exposure may be limited. Calcium is another important nutrient for older adults, as it helps maintain bone health and prevent osteoporosis and fractures. While dairy products are a good source of calcium, there are also plant-based options such as fortified soya milk, almonds, and certain types of bread.
Overall, a well-planned vegetarian diet can be safe and healthy for older adults, but it is important to be mindful of potential risks and deficiencies. It is recommended to consult a doctor or registered dietitian to ensure that nutritional needs are being met and to tailor an eating plan specific to an individual's health needs and concerns.

Types of vegetarian diets
A vegetarian diet at 70 can be beneficial, but it is important to consult a doctor and dietitian to ensure it is well-planned and nutritionally adequate. Older adults have different nutritional needs, and a plant-based diet may require careful planning to ensure it meets these needs.
There are several types of vegetarian diets, and it is important to choose one that aligns with your personal values, goals, and lifestyle. Here are some of the most common types of vegetarian diets:
- Pescatarian Diet: This diet allows for the consumption of seafood, in addition to plant-based foods. It is a good option for those who want to reduce their meat intake but still want the nutritional benefits of seafood, such as omega-3 fatty acids.
- Lacto-Ovo Vegetarian Diet: Also known as the traditional vegetarian diet, this allows for the consumption of dairy products and eggs, in addition to plant-based foods. It is a good option for those who want to avoid meat but still want the protein, calcium, and vitamin D found in dairy and eggs.
- Vegan Diet: This is the most restrictive vegetarian diet, excluding all animal products, including seafood, dairy, and eggs. It is often chosen for ethical reasons related to animal welfare and the environmental impact of industrialised animal agriculture. However, it can be challenging to maintain and may require supplements to avoid nutrient deficiencies, especially vitamin B12.
Other less common types of vegetarian diets include:
- Lacto-Vegetarian Diet: This diet excludes eggs but includes dairy products and plant-based foods.
- Ovo-Vegetarian Diet: This diet excludes dairy products but includes eggs and plant-based foods.
- Flexitarian Diet: This is a primarily plant-based diet that occasionally includes meat and animal products. It is a good option for those who want to reduce their meat consumption gradually or for environmental or cost-related reasons.
When choosing a vegetarian diet, it is important to consider your nutritional needs, especially as an older adult. A well-planned vegetarian diet can support weight loss, lower the risk of chronic diseases, and have positive environmental impacts.
