Are Vegan Diets Easy on the Nody
Story highlights
- A few weeks in, you may see more energy and a change in bowel function
- After several months, acne may clear up, but vitamin D might be lacking
Many people, though, seek a healthier diet. Research suggests that veganism can have health benefits, if well planned. For those who have pursued a diet rich in meat and dairy for most of their lives, embarking on a vegan diet can lead to significant changes within the body.
The first few weeks
The first thing that someone starting a vegan diet might notice is an energy boost with the removal of the processed meat that is found in many omnivorous diets, in favour of fruit, vegetables and nuts. These foods will boost your vitamin, mineral and fibre levels and thinking ahead about your meals and snacks rather than relying on convenience foods can help sustain consistent energy levels.
As time without animal products grows into weeks, there is likely to be a shift in bowel function either towards a more regular, healthy pattern or an increase in bloating, wind and loose motions. This is due to the higher fibre content of a vegan diet and the simultaneous increase in carbohydrates that ferment in the gut and can cause irritable bowel syndrome.
This may settle eventually and could lead to some positive changes in the diversity of the bacteria in the colon, depending on whether a vegan diet is made up of processed food and refined carbohydrates or is well planned and balanced. Although not proven yet, scientists believe that a high species diversity for gut bacteria could be beneficial for the whole system, in the same way that ecosystems are stronger as a result of lots of different types of species thriving.
Three to six months later
Several months into a vegan diet and some people may find that the increase in fruit and vegetables and reduced processed food can help acne to clear up. By this point however, your stores of vitamin D might be dropping as key sources of it in our diet come from meat, fish and dairy, and it isn't always noticeable until it's too late. Vitamin D isn't well understood but it's essential in keeping bones, teeth and muscles healthy and deficiency has been linked with cancer, heart disease, migraines and depression.
This is because vitamin D stores are only thought to last about two months in the body. How long your stores last will depend on the time of year that you decide to go vegan because the body can make vitamin D from sunlight. Making sure you eat plenty of fortified foods or take a supplement is important, especially in the winter months.
Within a few months, a well-balanced vegan diet which is low in salt and processed food may have impressive benefits for cardiovascular health, helping to prevent heart disease, stroke and reducing the risk of diabetes. As the intake of nutrients like iron, zinc and calcium are reduced on a vegan diet, our bodies get better at absorbing them from the intestine. The adaptation may be enough to prevent deficiencies in some people but not for everyone, in which case supplements can fill the shortfall.
From six months to several years on
Approaching a year on a vegan diet, vitamin B12 stores may become depleted. Vitamin B12 is a nutrient that is essential to the healthy functioning of blood and nerve cells and can only be found in animal products. Symptoms of B12 deficiency include breathlessness, exhaustion, poor memory and tingling in the hands and feet.
B12 deficiency is easily prevented by eating three portions of fortified food per day or taking a supplement, but managing it is very important, as any deficiency would negate the benefits of a vegan diet for heart disease and stroke risk and can cause permanent nerve and brain damage.
A few years down the line and even our bones will start to notice the change. Our skeleton is a mineral store and up until the age of 30 we can add minerals to it from our diet, but after that, our bones can't absorb minerals anymore and so getting enough calcium when we're young is vital.
After the age of 30, our bodies harvest the calcium from our skeleton for use in the body, and if we don't replenish the calcium in our blood through our diet, our bones fill the deficit and become brittle as a result.
Vegetables rich in calcium like kale and broccoli may protect bones, but many vegans don't meet their calcium requirements and there is a 30% increased risk of fracture among vegans when compared to vegetarians and omnivores. Plant-based calcium is also harder to absorb and therefore supplements or plenty of fortified foods is recommended.
When contemplating the years ahead on a vegan diet, balance is key. Well-balanced vegan diets may have major health benefits. Many of those benefits can be offset by deficiencies if the diet isn't managed carefully, but supermarkets and food outlets are making it easier than ever to enjoy a varied and exciting vegan diet and our appetite for meat overall is declining. With the right preparation, a vegan diet can be good for human health.
