BCAA and Immunity

Two weeks ago I wrote a piece on how to improve immunity during the winter months, focusing on training load and recovery, environment, psychology, clinical conditions and diet and lifestyle. In the coming weeks, I will look in more detail at the nutrients that can improve immunity, and outline ways to ensure adequate intake and variety of these nutrients to maintain health and help training and recovery. I'll kick things off by referring to a blog post that I wrote earlier this year on Branch Chain Amino Acids, a vital group of nutrients for health and recovery.

Peanuts and almonds are both good sources of Leucine, one of the three Branched Chain Amino Acids.

Immunity and the Athlete

Helping to maintain training during the winter months


An immune system which operates within homeostatic limits protects against common illnesses that can impair an athlete’s ability to train and perform.  Ensuring adequate carbohydrate and protein intake, a well as adequate intake of a wide range of micro-nutrients will help maximise the immune system's ability to protect against illness.  Improving immune health should be based around a five point plan:

1. Training - Load and Recovery

Adequate rest, alongside appropriate training, will ensure there is the right balance of overload and adaptation. Too much training with too little rest will lead to athletes becoming run down, and more prone to illness and injury. Sometimes, taking a day off when you feel run down or 'under the weather' may help prevent having to take a week of down the line.

2. Environment

There are some things that you cannot control, such as the training environment. However, you can be prepared. During the winter months, when the weather is likely to be colder and wetter, dress appropriately and keep warm whilst training and during warm up and cool down. Remember, just because it is cold, doesn't mean you don't sweat, so still pay attention to fluid levels and hydration, and ensuring that you shower and change out of damp clothing as soon as possible after training.

3. Psychology

High levels of stress and anxiety will also lead to a higher risk of illness. Try to reduce the risk of these feelings by focusing on things you can control, such as managing your time and meeting deadlines.

4. Lifestyle (Sleep, Diet, stress)

Be organised, ensure there is adequate rest and focus on healthy eating, meeting carbohydrate needs, adequately refueling, and choosing a wide range of fruits and vegetables.

5. Clinical conditions

There will be bugs and germs, and sometimes the sports environment is a perfect breeding ground for these to spread. Pay attention to good hygiene habits especially washing hands to reduce the risk. 

Supplements

Athletes can be quite quick to turn to vitamin and mineral supplements to prevent illnesses and time out of training. However. these should not be the first thing that the athlete looks to, and careful thought should be taken before this step is taken.
  • What is the likely benefit of the supplement, or the likely harm?
  • Are there any interactions between the nutrients, supplements and medications?
  • What is the evidence supporting these supplements
  • What is the cost, availability, and risk of contamination for the both the sport and the individual


In future posts I will look at some of the nutrients which are thought to reduce the risk of illness (including Vitamin E, Vitamin C, Vitamin D, Pro-Biotics, Glutamin, Zinc and carbohydrates), supporting claims for supplementing with these nutrients, and natural dietary sources for these nutrients.

Feeling a little peckish? Suitable lunch time meals

Aims
The role of lunch for an athlete is twofold. Its first is to assist with the recovery process after a morning training session  (if relevant), and the second is to ensure that your muscle glycogen stores are topped up ready for an afternoon/evening session. It has a third role in that it will also help concentration and energy levels in the afternoon for those at college or in employment.

Your training demands and needs will influence the size and content of this meal. Those who have a hard training session in the late afternoon/evening should take care to ensure that they are adequately fuelled.

Try to avoid missing lunch - you will often find this leads to more unhealthy food choices/snacks later in the day.

Examples
Salad Bar - Salad is a good option to start your meal as it provides a wide range of vitamins and minerals. Energy content is low, but you can increase this by including bread, jacket potatoes, pasta or rice. Add slices of chicken, ham or beans, pulses and nuts to increase the protein content. Beware of salad dressings which can be high in fat.

Soups - Vegetable soups are another easy way of getting a variety of nutrients in, and can be a substantial energy provider which is sometimes easier to consume and welcoming in the winter months. Homemade soups can be easy to make and to suit an individual’s taste and needs. Again you can boost the energy by eating with wholegrain bread, or by adding pasta.

Pasta/rice - Pasta and rise dishes are a good source of carbohydrate and are an even better option if you can choose wholegrain. Combine with a protein source such as fish or chicken and a sauce for a flavor. Adding a variety of vegetables to your pasta meal is a quick and easy way to increase nutrient variety of your meal.

Jacket Potato - Jacket potatoes can provide a quick easy energy source, and will digest quickly avoiding leaving you feeling uncomfortable before your training session. Including a high protein source such as tuna or chicken or even baked beans will give you an all-round high quality meal.

Dessert
Yoghurts and fruit are excellent choices for dessert, due to their nutritional value and low fat content. Although treat desserts are appealing, try to limit the intake of these at every meal and have a varied choice. Yoghurt is a good source of protein and good choices offer a good source of vitamins and low in fat and sugars. Combining with fruit will also add to the nutritional content of the meal.

Alongside the meal, ensure that at lunch and throughout the day you are taking fluids in to ensure hydration before a later training session.

Breakfast for athletes

There are many athletes who choose to train in the morning, before work, school or college; there are also sports that require training twice a day, one of these being in the morning. Some athletes will be able to consume a small amount of food in the morning before this session; others struggle to face anything until the training session is complete. Post training breakfast is an important way to ensure that adequate recovery is achieved and even if there is no morning training, a good breakfast is key to fuelling activities throughout the day. 

In terms of recovery there should be three aims:

Refuel - If training has taken place that morning or the night before, breakfast is vital to the recovery process, and helps to replace the muscle glycogen used during training.

Repair - During training, muscles are damaged.  It is important that you help your body repair these damaged muscles as soon as possible to aid recovery and prevent injury.

Adaptation - Training produces stimuli which cause your body to adapt so that it is able to cope with sessions better.  These adaptions, which include enhanced energy production and increased muscle size and strength, need energy to happen, and breakfast will help to fuel these after a morning training session.

What you can choose:

Cereals - Wholegrain cereals are a good choice as they provide quick and easy carbohydrate to help you refuel. Milk is a good source of protein, will help hydration, and is a good source of important vitamins and minerals like calcium. Many wholegrain and fortified cereal will also provide B vitamins and iron, both of which are important for energy breakdown.

Porridge - Porridge has Slow releasing energy, is high in carbohydrate and will keep you feeling full for longer. Milk will also add protein content and wholegrain oats will act as a good source of B vitamins. By adding a fruit compote, syrup or honey, a quick source of energy will be supplied which will help those who have had a hard morning training session.

Toast - Toast is another option for carbohydrates and toast from wholegrain bread will provide more nutritional value. If you wanted to add protein to toast you could choose a high protein spread such as peanut butter or serve with baked beans and or an egg (see below).

Baked Beans - Baked beans can be high in sugar, which can act as a source of fast carbohydrates which can be helpful following a hard training session.  Beans are a good protein source to go alongside toast.

Egg - Eggs are an excellent source of high quality protein, and contain most of the essential vitamins (except vitamin C). It is particularly rich in B vitamins, which are important for energy release, and Vitamin D, which athletes are normally low on. Eggs also contain antioxidants for healing, growth and fighting infection, which can be important during heavy periods of training for athletes.

Fresh Fruit - Breakfast is a good opportunity to get a healthy fruit portion in, so make the most of the selection that is on offer. Combine with your cereal or add to your porridge to boost the energy content, or simply take away for a mid-morning snack.

Yoghurts -  Yoghurts can be a good option on their own or with the addition of fruit or muesli. 

Hydration:

Not only is it important to refuel following morning training, but it is also important to make sure that all your fluid losses during training are replaced. Even if no training has taken place that morning, there has been a sustained period of time while you have been asleep and not taken any fluid on board. Ensure you are hydrated before you start your day.

Smoothies -  Are a great option for those needing extra energy or for those who may struggle with breakfast in the morning. To read a previous blog on Smoothies please click here http://www.athletelifedevelopment.com/resourceblog.htm

Concentrated Fruit Juice - This is a good option to be included with your breakfast meal and can count towards your portions of fruit and vegetables. Fruit juice will provide a good source of vitamin C which will not only help immune function, but also help the absorption of iron from your breakfast. If the athlete has had a hard morning training session, where sweat rates are high, fruit juice may not be the best option for rehydration, but a good option alongside water.

Squash/Water - Fruit juice and water will help rehydration following a session and should be drunk throughout the day. Squash has better rehydrating properties than water alone due to the solutes contained.

Coffee/Tea - The caffeine may help with alertness, but it’s not the best choice for hydration so try to have squash or fruit juice alongside.  Also, if you depend on coffee to wake you up in the morning, you may need to consider getting more sleep.

Hot Chocolate - Milk is now one of the most promoted recovery drinks and a natural source to. Its combination of protein and carbohydrate help promote recovery from training and it also includes many vital vitamins and minerals which many commercial recovery drinks fail to include. By adding coco powder to milk and warming provides a drink option which promotes recovery.

Short Days and Long Nights

As the nights get longer and colder, the hours of daylight become shorter, meaning that we see less of the sun and are exposed to fewer UV rays.

This is good news for those that burn easily, but its not just sun tans and sun burn that UV rays are responsible for. They also help produce a large proportion of our Vitamin D requirement as sunlight reacts with a precursor of the vitamin on the skin. Vitamin D deficiencies are becoming more common in athletes, partially due to the precautions taken to prevent skin damage from the sun.

While there is no strong evidence to suggest that Vitamin D deficiency leads to under-performance in athletes, it will have effects on their ability to train and recover and on injury risk. Athletes who are are Vitamin D deficient could be at increased risk of minor illnesses and stress fractures, ultimately leading to interruption in training and competition.

Vitamin D, along with Calcium, Phosphorous and Protein, has a key influence on the growth and mineralisation of bones. It is involved in the absorption of calcium, meaning an athlete could have a really good intake of Calcium within their diet, but if the Vitamin D levels are low, this won't be able to have a positive effect on bone growth and strength.

Vitamin D also has a role in immune function, making it an important nutrient for athletes involved in heavy training. 

Its not all doom and gloom though! Although sunlight is the best source of Vitamin D, small amounts can be taken in through the diet, particularly through fish sources - reiterating their importance within our diet.

Good Sources include:
  • Fortified Cereals
  • Eggs
  • Margarine
  • Tuna 
  • Sardines
  • Mackerel
So why not enjoy training outside and making the most of the daylight we have at the moment, and take advantage of the sources above in our diet. Simple meal ideas include- Jacket Potato or Pasta with Tuna and Sweetcorn, or an Omelet adding lots of different vegetables for variety and added nutritional benefit.

Can Pizza be Healthy?

Done right, pizza can be a great way to get your five-a-day! But all too often, the circular feast, taken straight from the freezer or dropped off by they delivery boy, contains nothing resembling a fresh vegetable and is topped with a small truck load of fat-laden cheese and peperoni.

This week's quick and simple recipe suggestion will give you some ideas of how you can enjoy the taste and convenience of a pizza without any of the guild.

1. Warberton's Square Wraps make a great base for a pizza-type snack.  They can be purchased in most large supermarkets, and cost approximately £1.30 for a pack or six.  They are cheaper than standard pizza bases, and cook much quicker.


2. Spread a generous layer of pesto or tomato puree across the base, taking care to reach right to the edges.  There is no need for fancy pizza topping sauces, and if you're feeling particularly enthusiastic you can make your own pesto.

3. Add toppings of your choice.  The pizza will only take 10-15 minutes to cook, so toppings should be chosen accordingly.  Raw chicken wouldn't be suitable, but cooked chicken leftovers would be a great addition.  Here are some other suggestions:
  • Any cooked meat
  • Smoked salmon or tinned tuna
  • Peppers
  • Courgettes, very finely chopped or thinly sliced
  • Mushrooms
  • Tomatoes
  • Sweetcorn
  • Onion
  • Garlic
  • Olives
  • Chilli Peppers
  • Pineapple
  • Sunflower seeds
  • Green leaves - rocket, spinach or basil
Avoid Peperoni and other high-fat, high-salt processed meats


4. Sprinkle some fresh or dried parsley, oregano or mixed herbs on top.

5. If so desired, top with a small amount of cheese.  Feta or cheddar are good choices.  Remember that the base is very thin, and the ingredients will be quite moist, so only a small amount of cheese will be required.

6. Cook in a hot oven until the base is crispy and slightly browned.

7. Enjoy!

Autumn Picking

I am lucky to be able to grow a lot of fruits and vegetables in my garden and as we start moving into the autumn months there is an abundance of blackberries to choose from and this year they seem to be much bigger than normal!

Although they are pretty simple to grow, there are also many to choose from on local hedgerows which can be just as good (although perhaps avoid those along the road side) and now is a good opportunity to take advantage of a good source of vitamins from this seasonal fruit.  

So what are the benefits of Blackberries?
Blackberries are packed with antioxidants including vitamin C and bioflavonoids like spinach, apples plums and grapes.  The dark blue not only provides another colour into your rainbow of fruits and vegetables to be eaten, but the dark colour also means it’s has one of the highest anti-oxidant levels of all fruits.

Vitamin C must be part of the everyday diet as the body can't produce it and it plays a role in exercise metabolism as well as to maintain health.

During exercise there is normally damage to muscles especially during harder workouts and this must be repaired in order for the athlete to recover and adapt. One function of Vitamin C is in the process of making collagen, and important ingredient in the repair of damaged muscles and tissue. It also reduces the amount of oxidative stress an athletes may suffer and therefor help to reduce the amount of illnesses picked up by athletes and allows them to train optimally.

As always Blackberries provide the best benefits in their natural state so an easy way to include them in your diet is as a smoothie or by adding them to cereals, I will include a simple apple and blackberry crumble recipe to this blog which provides an idea to use them for dessert.  

Tips for Blackberries:
Buying: If possible, don’t. Wild berries have a depth of flavour. Search out brambles near you avoiding roadside or polluted spots.  Even in cities you can find blackberries growing on scrubland, canal side paths and wooded areas.
Storing: Keep them cool and dry and eat within a day or two. Blackberries do freeze well and it’s a good idea to get a few bags in the freezer to use with apples throughout the winter.
Preparing: Wash thoroughly especially in they have been hand-picked. 

Simple Apple and Blackberry Crumble
(Prep 10mins, Cook 25mins and serves 4)
Ingredients:
Topping:
120g Plain Flour
60g Caster Sugar
60g unsalted butter
For the Fruit Compote:
300g Cooking Apples
30g unsalted butter
30g sugar
115g Blackberries
¼ tsp ground cinnamon
  1. Heat Oven to 190C Gas Mark 5
  2. Crumble Topping: Tip the flour and sugar into a large bowl and add butter. Using your fingertips rub the butter into the flour to make a light breadcrumb texture.
  3. Compote- Peel and core the apples into small chunks. Put the sugar and butter into a saucepan and melt over a medium heat. Cook for 3mins until the mixture turns to a light caramel. Stir in the apples and cook for 3mins
  4.  Cover, remove from the heat and leave for 2-3 minutes in the pan
  5.  Add the compote to the cooking dish and add the crumble topping to the top of the mixture and also add some muesli or oats to add nutritional value and then cook in the oven for 20-30mins- until the crumble topping starts to brown.

Simple, nutritious smoothies and juices

The recent spell of fine weather has inspired me to get back into smoothie-making mode.  Summer months are an ideal time for smoothies as the seasonal berries provide a tasty addition, though this week I have been using the end of last year’s blackberries and loganberries from the freezer.

Smoothie and juice making can be as simple or as complicated as you make it, and the fruit (and vegetables) that you use is only limited by your imagination.  Rolled oats, ground almonds, sesame seeds, and peanut butter are just some of the other ingredients that you can use.  Milk, yogurt, coconut milk or almond milk can be used to add extra smoothness and increase the protein content, and nutmeg or ginger will give an extra kick to any juice.

Smoothies are high in vitamins and minerals, a great way of getting some or all of your 5-a-day, and are higher in fibre than traditional juices because they retain the pulp and skins.  They are also easier to make, and don't produce waste.  Smoothies are a particularly easy way of getting vital calories and nutrients in after a hard session on a hot day when you might not feel like eating food, and they can help to rehydrate you (read last weeks blog about hydration here).  Many fruits also contain natural chemicals which help increase appetite.

This is my basic go-to smoothie recipe
  • Apple (cored and quartered) and/or banana to give it a nice texture and adds thickness
  • Orange juice to make it more runny.  You can also use pineapple or apple juice, and if you have a juicer you can make the juice yourself.
  • Frozen raspberries, blackberries, loganberries or similar berry to give it taste.  The frozen fruit means that the smoothie is already cool.  Add some ice cubes if the fruit is fresh.
  •  Blend all the ingredients together in a blender for 30-40 seconds.Server more or less immediately.  Mind the brain freeze.
Like all my recipes, I don’t get too hung up on measurements.  I go with what I think is roughly right, and if it’s too thick, I just add more orange juice. If it's not thick enough, I add another apple or banana.

You don’t have to follow any particular recipe to make a great post-training snack or a nutritious drink to kick-start to the day.  Add something to give it texture, something to give it juice, and something to give it taste, and focus on what’s available to you at a reasonable price.  

And smoothies don’t have to be expensive.  Pick blackberries in the late summer (they’re free in most hedgerows!) and freeze them to use throughout the year.  Because any fresh fruit you add will be high in vitamin C, you can use 'from concentrate' juices to keep the cost down.

Smoothies are a great way of using up ripe fruit.  If you have bunches of bananas that are getting ripe, you can peel them and freeze them for use in future smoothies.

Juicing require more cleaning up afterwards.  Fruit and vegetables need to be very ripe, and some produce little juice, creating a lot of waste.  If using frozen fruit, ensure that you let them thaw first, or you'll end up with a lot of waste and practically no juice at all.  Juices can be diluted with refrigerated mineral water or sparkling water.

Any sort of blender will suffice for making smoothies, though there is a range of juicers and smoothie machines on the market.  Smoothie machines have some additional features over traditional blenders: a pouring spout, durable blades for crushing ice, and a pusher to ensure that the fruit and vegetables are all blended properly.  Juicers actually separate the juice from the pulp, skin, seeds and other debris, creating a large amount of waste, but providing a great way to make your own orange, apple or pineapple juice. Masticating and hydraulic juicers are more efficient (i.e. produce more juice) than centrifugal juicers, but are also more expensive. A number of other fruit and vegetables work well as juices, and in most cases, combining juiced fruit with blended fruit will give the best results.
