Nutrition for Young Athletes

July 28, 2013April 3, 2014Leave a comment

Why a nutritious diet is needed:

Normal growth and development
Healthy, strong body
Energy for everyday activities – school, gymnastics training
Repair of muscles following demands and stresses of training and competition

Main components of the diet:

Hydration:

as important as food
Overheating and dehydration can be dangerous (heat stroke)
Low levels of dehydration: reduced strength, stamina, concentration

Carbohydrate:

Supply energy for muscles
Immunity
Growth
Focus on wholegrain bread, pasta, rice, fruit, veg
Especially important before and after exercise for muscle energy

Protein:

For muscular strength & power, muscle repair & maintenance
Focus on lean protein: chicken, fish, eggs,
dairy, beans, seeds, nuts

Healthy Fats:

Important for healthy heart, nervous system, hormones etc.
Focus on healthier fats from olive oil, oily fish eg. Salmon, avocado, peanut butter etc.

Vitamins & Minerals:

Calcium – strong bones
Iron – needed for blood cells to transport oxygen to muscles
Vitamin D – bone development, also implicated in long term health issues
B vitamins – energy production & protein metabolism
Omega 3 fats – oily fish, for brain development, heart health, vision etc.
Generally, supplements not needed if child has varied diet
Consider fish oil supplement (omega 3 fats) if intake of oily fish is less than once per week
Consider Vitamin D supplement if always wears sunscreen in summer

Pre – exercise fuelling:

Aim to have a meal or a substantial snack a few hours before:
- Pitta/crumpets/toast with jam/honey/peanut butter + milk
- Jacket potato + tuna/baked beans
- Baked beans on toast
- Boiled egg and toast
- Porridge, milk and raisins/berries
- Breakfast cereal with milk
- Bread roll with cheese/meat filling + banana
- Pasta, rice or noodles with tomato sauce, lean meat eg. chicken, vegetables

Up to 1 hour before
- Fluid for hydration: 200mls fruit juice/water/skimmed milk

Early morning sessions: If training or competition is first thing in the morning, it is probably not possible to have a meal 3-4 hours before. In these circumstances, have a good meal the night before, then a snack and fluid 1-2 hours pre exercise eg. breakfast cereal and milk, fruit and yoghurt, smoothie or milkshake.

After exercise:

Ensure your child has a snack, or a meal following training. Carbohydrates replenish the muscles with glycogen for energy, while protein repairs and rebuilds muscle tissue. Sports protein shakes or supplements are unnecessary and not advised.

Post-exercise snack ideas (follow within a few hours with a meal):

Homemade shake – blend 200ml milk, tablespoon yoghurt, banana, tablespoon honey
Low fibre breakfast cereal eg. Cornflakes/Rice Krispies and milk
banana and yoghurt/milk
Bread roll or sandwich with cheese/meat/fish filling

Rehydration

It is highly likely that your child will finish training with some degree of dehydration, therefore it is important to replace these fluids as soon as possible after the session. Aim for 200ml fluid with an hour of finishing.

Body image and Disordered Eating

In some sports there is pressure to ‘not get fat’/stay lean or to bulk up to enhance performance Eg. Gymnastics or rugby.

Any such pressure can have the opposite effect – unhealthy eating patterns, restrictive eating (anorexia), or bingeing (bulimia).

Poor nutrition, resulting in weight loss, can cause anaemia, reduction in muscle power and performance, weak bones, poor concentration and increased injury risk

Tips for parents:

Do not weigh your child (unless specifically asked to do so for medical reasons)
Do not discuss calories or fat, unless raised by your child. Approach in a positive manner e.g. food gives us energy for exercising and being strong. Healthy fats are important for us to be healthy.
Talk about food being nutritious, for making us strong, repairing cuts in our skin, building our muscles, giving energy for running fast etc.

Coconut Water – worth the hype?

July 27, 2013December 27, 2014Leave a comment

Since the introduction of coconut water to the UK market, sales have sky rocketed, helped by its rapid take-up among celebrities and high-profile investments from beverage companies. The UK coconut water industry was be worth £100m in 2014.

Vita Coco coconut water

Vita Coco accounts for 94% of UK coconut water sales in the UK, and is available everywhere from Selfridges to Tesco’s. So what do Vivia Coco say about their product, and does it live up to these claims?

all natural – true, taken from young coconuts, some added vitamin C
super hydrating – true, water and other sports drinks also super hydrating
fat free – true, water and sports drinks also fat free
cholesterol free – true, all fruit & vegetables are cholesterol free
potassium packed – true, same amount as 2-3 bananas
nutrient stacked – not really – has great amounts of vitamin C, very little of any other nutrients.

So as you can see, most of the claims are true. However, water and other sports drinks also carry the same benefits. The extra potassium could be of benefit for people who have a poor intake of fruit, vegetables and dairy.

Staying hydrated is one of the most important things for recreational and professional athletes. If you are exercising for under an hour, and if the taste of coconut water helps you drink plenty of fluids, it is a fine choice for most people, but water is just as good.

For those exercising strenuously and for longer than an hour, especially in hot conditions where perspiration is high, you need easily absorbed carbohydrate for quick energy and to replace lost electrolytes like sodium and potassium. Coconut water doesn’t have the ideal levels of carbs or sodium. For post exercise, it has neither the calories, carbohydrate or protein required for optimal recovery.

My advice?

It’s a healthy replacement for sugary fizzy drinks or fruit juice, as with 90kcal per 500ml carton, it has half the calories. However, it provides no extra hydration benefits over water for the average recreational exerciser. For strenuous and prolonged exercise it is fine, but would need to be taken with a snack for extra sodium and carbohydrate.

Boosting immunity to stop getting sick

July 26, 2013June 28, 20151 Comment

It’s an unfortunate inevitability that at some time or another, illness will descend upon any work place.

Gastroenteritis can be difficult to avoid and in environments where there is close contact, it can spread like wild fire. Washing hands is vital to avoid infection, alcohol gel can also be used, but is not as effective as thorough hand washing. Here’s what the NHS says on medical treatment.

From a food point of view, it is especially vital for athletes to try to maintain nutritional intake to prevent muscle wastage and maintain energy levels. Easier said than done when you can’t keep anything down! If possible, and even if there is no appetite, small amounts of plain food and higher calorie fluids eg. toast, fruit juice, breakfast cereal, plain biscuits, or any food that you feel you can tolerate should be eaten.

It is possible that following recovery from gastroenteritis, the gut may have become intolerant to lactose (milk sugar), causing continued diarrhoea, and possibly abdominal pain and bloating. This is because the enzyme, lactase, which breaks down the lactose has been affected. Normal milk can be replaced with Lactofree Milk, tolerance to other dairy products varies. A dietitian can advise further on lactose avoidance.

In a previous post, I discussed the numerous reasons for lowered immunity during training for athletes:

repeated cycles of heavy exertion
exposure to germs and bugs
mental stress
lack of sleep
poor nutrition
weight loss

The first two points, repeated cycles of heavy exertion, and exposure to bugs certainly apply to the London Irish squad in pre season training, hopefully less so the mental stress, lack of sleep, poor nutrition and weight loss.

So what can be done to reduce the possibility of becoming ill?

Nutritional immunology is a rapidly growing area, and four key principles have emerged:

1. Almost all nutrients in the diet play a crucial role in immunity. A varied, healthy diet provides all these nutrients in most healthy adults, and mega doses of vitamin/mineral supplements do not “boost” immunity above normal levels.

2. Poor energy and nutrient intake can reduce the immunity and susceptibility to germs and bugs. Poor protein intake reduces immune function and strongly increases risk of various types of infections.

3. Some nutrients (glutamine, arginine, fatty acids, vitamin E) provide additional benefits to immunocompromised persons (e.g. the frail elderly) or patients who suffer from various infections. Currently there is a lack of evidence to support the use of these in preventing exercise-induced immune suppression and protection from infection.

4. Some supplements may prove useful in countering immune suppression for healthy adults during unusual mental and physical stress e.g. omega-3 fatty acids from fish oils reduce inflammatory responses.

CARBOHYDRATES

Of the various nutritional countermeasures that have been evaluated so far, carbohydrates before, during, and after prolonged or intense exertion has emerged as the most effective way to ensure less of a negative effect on the immune system. Athletes intent on reducing body fat by avoiding carbohydrates should be aware that this may impact on their immunity.

Strategies to ensure good carbohydrate stores to optimise immunity:

Have a carbohydrate-based snack before you start high intensity training, particularly hard morning training. If you are unable to tolerate something before you start exercise, have a source of carbohydrate during the session such as a sports drink (6-8% carbohydrate)
Have a carbohydrate-based snack shortly after training to start the recovery process. This is of particular importance for athletes training more than once a day with limited time to recover for the next session.
Base meals around nutrient-rich carbohydrate-containing foods and fluids. Rice, pasta, bread, cereals, fruit, starchy vegetables and low-fat milk and yoghurt are nutrient-packed carbohydrate-containing
Balanced meals with carbs, protein & veg

choices. The aim is to match daily carbohydrate needs with an appropriate amount of carbohydrate-containing foods and fluids throughout the day.

PROBIOTICS

images-2

Probiotics may benefit athletic performance indirectly by maintaining gut function and health, preventing the immunosuppressive effects of intense exercise, and reducing susceptibility to illness. Substantial evidence exists indicating that probiotics can reduce susceptibility to acute infectious diarrhoea (athletes may be particularly susceptible during foreign travel). Probiotics come in tablet or liquid form eg. Yakult. Tablets tend to be more potent, and are available from health food shops.

A balanced and nutrient rich diet is fundamental to avoiding illness for those undergoing intense physical exercise. Current opinion is that athletes should invest in nutrient-rich foods and fluids that provide sufficient energy and a wide range of vitamins, minerals and other important chemicals, such as phytochemicals, found naturally in foods. When this is not possible the use of supplements such as multi vitamins and omega-3 fish oils.

Pre-season Overload Week – we’re on a high. Why?!

July 24, 2013July 25, 2013Leave a comment

Mid-way through the intense Overload week of pre season rugby training, and Dec’s exhaustion levels don’t seem too extreme.

He was even able to hold a conversation last night, and levels of irritability appear low (at dinner he soldiered on admirably when there was no pesto for the pasta – he rescued it with a dollop of hot pepper sauce).

Possible reasons for being cheerful:

the old body is feeling good: during previous pre seasons he was heavier, weighing in at up to 110kg, making training a bigger effort and therefore more tiring. The attention to diet may be making a difference to fatigue levels…..a balanced intake of real nutritious foods, rather than over emphasis on high protein, low carbohydrate and supplements.
pre season training is going well, with the squad bonding
today was a day off training, just a pilates session and physio
he’s enjoying coaching the boys at Ealing Rugby two nights a week…..a new routine is as good as a holiday!
our two eldest children are in N. Ireland with their Granny and Grandpa for a week. This means a bit of peace (we do like to spend time with our children, it’s just that these two ~~nutters~~ are the antithesis of the ‘children should be seen and not heard’ parenting philosophy)
he’s beside himself with joy at the birth of the nation’s new Prince

So last night’s dinner was rescued with some hot pepper sauce. It had me thinking, what are the food items we always have in the fridge or cupboard? The “Desert Island” products (idea poached from Radio 4 Desert Island Discs, this is my Kirsty Young moment). Obviously we do eat other things, like the staples of meat, fish, vegetables and pasta/rice etc.

Our Desert Island List:

Oats – for the porridge in the morning, essential slow release carbohydrate for the training day ahead. Made with milk for calcium and protein, raisins and some sugar for faster releasing carbs and to make it taste better. Also use oats to make biscuits, flapjacks and in smoothies.
Eggs – powerhouses of nutrition. One of the best sources of protein, containing all the essential amino acids, including leucine (big selling point of many protein supplements). Don’t worry about the cholesterol as it is poorly absorbed by the body. Scrambled, boiled, omelettes, egg fried rice.
Yoghurt – I prefer to buy natural unflavoured yoghurt as it has no added sugar and usually has probiotics (good for gut health and immunity). Any brand will do, but I’m a fan of the massive tubs from Lidl (about £1.50 for 1kg). I can add berries/chopped fruit/put in smoothies etc. Dec likes the new Danone ‘Danio” higher protein yoghurts (13g protein/pot) which are sweetened with fruit and sugar.
Fruit – for snacks, no explanation needed for the benefits of the vitamins, antioxidants, fibre, carbohydrate etc.
Nuts – a handful of almonds as a snack, or peanut butter on toast. Healthy fats (cholesterol lowering), high protein so filling and good for muscle repair/building
Coffee – for a wake up kick, afternoon kick, evening kick. Means we don’t have to physically kick each other to wake up! Contrary to popular belief, it’s not dehydrating and has many health benefits. Also useful to have pre training as caffeine enhances performance (ergonomic)! At London Irish, some of the boys are in their Coffee Club, where they enjoy a swift Nespresso before hitting the training field/weights room.
Hot Pepper Sauce – as previously discussed, this can rescue a meal
Hot Pepper Sauce

that may be lacking in flavour. Used like tomato ketchup. Personally, I think it destroys any hope of actually tasting the food you put it on (mmmm, not saying a lot for my cooking skills, is it?!)
Cherry Diet Coke – this is the Desert Island luxury item, Dec’s ‘treat’. I get a bit twitchy and Food Police when he reaches for the 3rd or 4th can of the day. There’s not much good to say about Diet Coke, it’s nutritionally sparse, and there are question marks over it’s long term health affects.

So here’s hoping the happy state remains with us until Saturday when a week off training starts, watch this space!

Healthy ice cream – high protein, low fat

July 18, 2013Leave a comment

Here’s a recipe for ice cream made with protein powder. I used Kinetica Whey Protein Strawberry flavour. It is a much healthier version of standard ice cream, as it is low in fat, and high in protein, and has healthier carbs. Perfect as a post workout recovery snack, or just for something delicious on a hot day.

Per serving:

208kcal, 18g protein, 25g carbohydrate, 4g fat
Normal ice cream per 100g (3/4 cup): 200kcal, 3.3g protein, 23g carbohydrate, 11g fat

Why it’s better than standard ice cream:

cream replaced with whey protein powder, yoghurt and milk.
higher in protein – for muscle repair and muscle building, makes you feel full up for longer.
lower in fat – 17% calories from fat, compared to 50% in standard ice cream
healthier carbs – banana and milk replace sugar. Carbs used for muscle repair and building (helps to shuttle protein in to muscle), replaces glycogen used up during exercise.
banana provides vitamins, minerals, antioxidants and soluble fibre.
you can have a larger portion size than standard ice cream as it is lower in kcal.

You can use any flavour of protein powder that you like, I used strawberry. I don’t have an ice cream maker, but I’m sure the results would be even better using one!

And the recipe…..(makes 2 servings):

30g any whey protein powder

250ml semi skimmed milk

1 banana

2 tablespoons natural yoghurt

Whizz the ingredients in a blender, and pour in to a bowl. Place bowl in the freezer.

After about an hour, take out of freezer and stir using a whisk or fork. This is to break up the ice crystals. Try to get a smooth consistency.

Repeat this every 30 minutes/1 hour until the ice cream has been in the freezer for approximately 4 hours. If it is left longer than this, it can become quite solid, and will need to be left out of the freezer for a while to defrost a little before serving.

Enjoy!

Paleo Diet – a bad fad?

July 16, 2013August 12, 20145 Comments

A nice chap on Twitter challenged my thoughts and opinions on the Paleo Diet. Am I a lover or a hater?

It could be considered standard practice for a health professional to dismiss the Paleo Diet as nothing but a fad, a diet that is BAD, and just a bit mad. However, I am of the opinion that most ‘diets’ have their pros and cons, work for some people and not for others. As I always say, what works for you and what you are happy with is your business. If you feel the need to change and want to change, that’s terrific too.

Here is a bullet point overview of the paleo diet. I could witter on forever about it, but I’ll try to keep it brief!

What is the Paleo Diet?

short for paleolithic, also known as hunter-gatherer or caveman diet.
consists mainly of fish, grass-fed pasture raised meats, eggs, vegetables, fruit and nuts
excludes grains (including wheat & rice), legumes, dairy products, potatoes, refined salt, refined sugar, and processed oils
based on the premise that humans have not evolved to digest and metabolise the excluded foods
seen as a lifestyle, rather than a ‘diet’ one ‘goes on’

Pros

based on wholesome, unprocessed foods, high in vitamins and minerals (except calcium), antioxidants, and essential fatty acids
elimination of processed foods
no specialist ‘diet foods’
eat when you’re hungry, don’t eat if you’re not
when strictly followed, will probably result in weight loss due to a reduction in calories
no calorie counting required – a massive plate of veg with a portion of meat should fill you up
many people do have a gluten/lactose intolerance, the diet can help identify these

Cons

restrictive, can result in feeling deprived leading to rebellion and over eating
requires careful planning and a lot of will power
eating out and as a guest at other people’s houses can be very difficult
expensive to buy pasture raised meat, wild fish (£10 per salmon fillet anyone?) etc.
there is the opinion that the whole philosophy is based on speculation about what our ancestors ate
humans have not stopped evolving, an example being the evolution of lactose tolerance in Europeans

What about for athletes?

Having witnessed first hand the implementation of the Paleo Diet with professional athletes, I’m more skeptical about it’s application for sports people. The leading expert on all things Paleo, Loren Cordain, followed his original book with one on the diet for athletes. Just one of the aspects which I find tricky is the use of carbohydrate. He fully acknowledges the need for adapting the diet for very active individuals, advocating that 50% calories should come from carbohydrate, including the introduction of potato, sweet potato, dried fruits and fruit juice. In the book ‘The Paleo Diet for Athletes’ he writes:

“of course, this carbohydrate should primarily come from fruit and vegetables, so calories aren’t wasted by eating food lacking micro nutrients”.

He follows with an example diet for a 10 stone athlete training 15 hours/week requiring 3000kcal/day. I analysed the nutrients…… Dr Cordain only managed to get 30% calories carbohydrate (fruit/veg), and this seemed to be mainly from fruit juice. I therefore question how athletes requiring large calorie intakes can realistically follow his regimen.

Due to the impossible task of getting 50% of calories from fruit and veg, I have witnessed first hand the reduction in training performance (feeling weak and dizzy), constant hunger, poorer body compostition, and difficulty in socialising (as a dinner guest or in restaurants).

My opinion:

For people who have a high intake of processed food, are over weight or who want to try to improve their health, a relaxed version of the Paleo Diet may be worth a try! There is no doubt that wholesome, unprocessed

include wholesome grains and dairy

foods: fish, meats, eggs, vegetables, fruit and nuts are of benefit. Adopt a common sense approach to including grains and dairy eg. swap Frosties for oats, chips for basmati/brown rice.

Athletes, be careful not to sacrifice your performance in training and in competition for an ideological diet that is not meeting your nutritional needs. The basic principles can be adapted to meet your training goals and to achieve optimal performance.

Final thoughts:

“You can’t out run your fork” for optimal health, diet is paramount
Eat wholesome real foods, eat food that goes off before it goes off!
Load your plate up with vegetables, a handful of grains and a portion of protein
Make small changes over a period of time so that it becomes a lifestyle, not a fad diet that you follow for a few weeks

Your thoughts?

I’d love to hear your thoughts, opinions and experiences! Comments gratefully received…….

Breakfast Omelette (sweet!)

July 14, 2013July 16, 20133 Comments

Most of us have become used to having something sweet in the mornings, rather than savoury. Think breakfast cereal, porridge with raisins, muesli, toast and jam, fruit and yoghurt etc. All perfectly great breakfasts.

Omelettes usually fall in to the savoury category, so I thought I’d change ingredients to make it sweet. It sounds a bit odd, but bear with me, and give it a go. All you need are eggs, oats and some honey. Cinnamon if you are feeling adventurous!

Why this omelette is great!

Eggs:

contrary to popular belief, cholesterol in eggs does not raise blood cholesterol
nutrient dense superfood, choca-block with vitamin and minerals
high in choline (neurological benefits) and leucine (for muscle building – found in many sports protein drinks)
High protein – help you to feel full up for longer and for muscle building
cheap!

Oats:

low GI, for slow energy release
high soluble fibre and B vitamins
lowers cholesterol, prevents heart disease
also cheap!

Honey:

balance of fructose and glucose sugars (similar to sports carbohydrate gels, but without the additives)
easily absorbed by the body, increasing energy levels quickly

Here’s what you do:

1) whisk 2 eggs, add to hot non-stick omelette/frying pan

2) sprinkle in a small handful of oats, with cinnamon if you are using

3) give the pan a shake every so often and just a few times give a stir (stir too often and you’ll have scrambled eggs, equally delicious I’m sure)

4) drizzle some honey over the omelette

5) plate up! Add some extra honey if you wish.
