What we can learn from the Blue Zones

24/1/2022

0 Comments

Have you heard of the Blue Zones? The term ‘blue zones’ was coined by the author Dan Buettner and his team following research on the five places in the world where there are an unusually high concentration of centenarians (people living over 100 years old) and supercentenarians (people living over 110). These five places are 
Sardinia in Italy, Okinawa in Japan, Loma Linda in California, Nicoya in Costa Rica and Ikaria in Greece. 
 
We are going to look into the research done on these areas to see what we can learn from them from a mostly nutritional perspective, but as we know health is very much holistic rather than just being about one aspect, so there are several important lifestyle elements to be understood in living a long healthy life. 

 
Sardinia, Italy 
In the mountain village of Arzana the classic Sardinian diet consists of fruits, vegetables, wholegrain bread, beans, sheep’s cheese and goat’s milk.  Meat is only featured occasionally, usually on Sundays or special occasions. Many Sardinian centenarians also drink red wine in moderation (around a small glass a day). Being a fairly isolated mountain village, they have strong social connections and a ‘family first’ ethos where elders are well respected. The majority of the men in this area who are now centenarians were once shepherds and walked many miles each day on mountainous terrain.
 
Okinawa, Japan  
The Japanese island of Okinawa is home to some of the world’s longest-living people. The older Okinawans eat a mostly plant-based daily diet of vegetables, sweet potato, miso and tofu. Some pork is also eaten in small amounts and is usually reserved for special occasions. They practice eating until 80% full and then stopping. The Okinawans are traditionally active and enjoy walking and gardening, there is a sense of community amongst the elders and all centenarians interviewed said that they had a strong sense of purpose. 

 
Loma Linda, California 
In the city of Loma Linda, there is a population of Seventh-day Adventists whose faith promotes healthy living and discourages smoking, drinking alcohol, caffeine, eating meat and ‘rich foods’, with many following a vegetarian diet. They have been studied extensively as a group of around 9000 individuals, with studies showing they exercise regularly, including into older age. The Seventh-day Adventists observe a sabbath once a week where they detach from the business of their daily lives and focus on God, family and nature. They have strong social bonds with others in their community. 
 
Nicoya, Costa Rica 
As common with all the above places, the people from the village of Nicoya in Costa Rica enjoy a relatively simple life. Their traditional diet consists of beans, rice, corn, tortillas, vegetables, fruit, with some eggs, and pork. They tend to eat their largest meal in the middle of the day favouring lighter evening meals. The elders in this area enjoy a good sense of purpose, solid family ties and are religious. Many that were interviewed also stated that they walked a lot, and that although they had a strong work ethic, they lived low-stress lifestyles. 
 

Ikaria, Greece 
This Greek island enjoys the traditional Mediterranean diet rich in vegetables, salads, herbs, goats milk, bread, honey , lentils, chickpeas and some fruit. Their diets were found to be low in dairy and meat, which would be served on special occasions. They drink a small amount of wine daily and enjoy herbal teas made from fresh local herbs such as sage, oregano and rosemary. 
The elders live active lives, walking and doing manual work in the house and garden. The pace of life is gentle and there is a strong sense of community. 
 
CONCLUSION
As we have seen these 5 blue zones have a lot in common. There isn’t one single practice that they all do, but rather a combination of things that enable good health. It could be though that these areas put their longevity down to genetics however in the book it is stated that although this could potentially be a factor in Sardinia, in Costa Rica this isn’t the case as the village is considered more mixed-blood race, and that diet and lifestyle are still the biggest influences on long-term health.  

 
To summarise, the most common themes across the 5 blue zones are:

  • Eating fresh, unprocessed whole foods which are naturally high in nutrients 
  • Lowering meat consumption to a minimum
  • Walking every day 
  • A slower pace of life and regular downtime 
  • Felling part of a community
  • Having a strong sense of purpose 
  • Most of these places enjoy plenty of sunshine 
 
So now look at your life and see where you can make some shifts to implement some of these long-term healthy changes. Some of these may be easier to implement than others. However, they are all valuable ingredients for an overall sense of wellbeing and health, and longevity too!

Pre and post-match nutrition for recreational tennis players

28/12/2021

0 Comments

I was asked to write about this for a local tennis club and thought I would add on here for anyone who is keen to optimise their tennis performance and recovery through nutrition. ​

Fuelling your body the right way before and after a tennis match is important for sustained energy, optimal performance, fuel for your muscles, better recovery, muscle repair, healthy bones and injury prevention. 
​
Let’s look at the food groups that should be covered before and after matches, and the best times to eat these foods. I have also provided some snack and meal ideas so that you can easily put this guidance into practice. 
 
Pre-match nutrition 
The body’s preferred energy source is glucose which comes from carbohydrates. It is important to eat something before you play, but what you eat pre-match is dependent on timing. Ideally you would eat a carbohydrate-based meal 2 to 4 hours beforehand, however sometimes you may have no choice but to eat closer to your match, for example if you are playing early in the morning. If you do have an early morning match, eating a largely carbohydrate-based meal such as pasta or rice the night before will top-up your glycogen stores (this is glucose that your body stores to use when it exercises) so you can then just eat something light in the morning. 

As a general rule, follow the below advice on what to eat and when: 

  • Less than 1 hour before - keep it light and carbohydrate based such as a banana, a slice of toast with honey, dates or a few rice cakes. 
  •  1-2 hours before – aim for a carbohydrate-rich or snack which is low in fibre, low in protein and low in fat. The reason for avoiding too much fat or protein pre-match is that it takes more energy to break down and you want to keep as much energy as you can! Some ideas are: 
  • A banana 
  • Toast with honey, nut butter and banana slices, or hummus 
  • A cereal bar 
  • A smoothie containing fruit, milk of your choice, 1 tbsp oats, 1 tbsp Greek or soya yoghurt
  • Greek or soya yoghurt with fruit 
  •  2-4 hours before – this is more likely to be a meal which should ideally be carbohydrate rich and contain low to moderate fibre, moderate protein and moderate fat. Again this is to prevent the body having too much work to do by breaking down rich fatty foods or high protein meals, so keep it fairly simple. Some ideas are: 
  • Porridge with some nut butter and fruit 
  • A tomato-based pasta with grated cheese 
  • Jacket potato with hummus or tuna 
  • Chicken or tuna salad wrap  
  • Tomato and mozzarella bagel 
  • Risotto 
 
Post-match nutrition 
 
Nutrition is just as important after you play to aid recovery. Ideally you should eat within a couple of hours of finishing your match. The nutrients that are essential post-match are:  
  • Carbohydrates – to restore energy by replenishing muscle glycogen stores, to provide energy for muscle repair and growth.  
  • Protein – for repair and rebuilding of muscle fibres, tissue repair and bone health.
  • Fats - to allow the absorption of fat-soluble vitamins which are important for optimal bone health and recovery. 
 
Here are some examples of post-match snacks or meals. These are all fairly simple and easily digestible foods in most individuals, meaning that the nutrients can be absorbed readily and do their job more quickly. 

  • Smoothie with fruits, Greek yoghurt or protein powder, 1 tbsp nut butter or chia seeds, 1 tbsp oats, milk of your choice. 
  • Greek yoghurt with berries and banana and low-sugar granola.
  • Eggs and avocado on toast 
  • Falafel with wholemeal pitta, tzatziki and salad  
  • Rice bowl with salmon, avocado and vegetables 
  • Tuna salad sandwich in wholemeal bread 
  • Chicken with quinoa and vegetables drizzled with olive oil  
  • Spinach and mushroom omelette with toast 
  • Chickpea curry with brown rice and a spoonful of natural/coconut yoghurt
  • Fish with sweet potato, salad and pine nuts 
 
Remember that hydration is also essential at any time, so ensure that your fluid levels are topped up before, during and after you play.  
 
I hope this has given you some ideas, and helped you to understand how optimal nutrition can help with your performance and recovery. Please note that any food ideas are just guidelines and to adjust accordingly if you have specific dietary requirements.

Nutritional notes
 
Miso – Miso paste is made from fermented soya beans. It can be high in salt in large quantities. Because it is a fermented food it contains probiotics which are ‘good' bacteria that may help improve the balance of bacteria in the gut if consumed regularly, beneficial for good digestive health and immune health. Miso also contains isoflavones which have antioxidant properties.  
 
 
Cauliflower – Cauliflower is packed with beneficial nutrients, it really is a superfood. It is fibre rich and contains and array of vitamins and minerals. Cauliflower is particularly beneficial for health as it contains some powerful phytochemicals called glucosinolates, isothiocyanates and sulforaphane which are important antioxidants that have been found, in studies, to slow the growth of cancerous cells and have protective effects against certain forms of cancer. Studies have also shown sulforaphane may be helpful in the prevention of heart disease and diabetes. 
 
 
Edamame beans - theses are young soy beans. They are a rich source of protein and contain all the essential amino acids, meaning they are a ‘whole’ protein source. This makes them a great addition into a plant based diet. They are a good source of fibre and contain a good level of folate and vitamin K1. They also contain the group of phytochemicals called isoflavones which have antioxidant properties.

Vitamin D - keeping your levels optimised through autumn and winter

13/11/2020

Vitamin D heading
As we say goodbye to the summer sun, our vitamin D levels start to decline as we head into autumn and winter. If you had plenty of sun exposure over the summer, your levels of vitamin D may keep you going for a while, however due to indoor lifestyles, many of us don’t even get adequate exposure in the summer, meaning that by wintertime you may find that your levels decline down to a deficient or insufficient state. Approximately 1 in 5 people in the UK have deficient or insufficient vitamin D levels. From my experience in clinic, this is something that I see a lot of, regardless of the time of year.

Runner's legs on autumn leaves
Most of us have heard about the many amazing benefits that regular exercise can provide for your health, including good cardiovascular health, mental wellbeing, weight control, blood glucose control and improved musculoskeletal health. But can these health benefits alone motivate people to exercise in some way 5-7 times a week? For some people this may be more than enough, but for others, if the enjoyment factor is missing, it will be a lot harder to get motivated and there will always be something more pressing to attend to!
