Throw some Z’s 
Lying in bed, restless and trying to get to sleep (or back to sleep), and feeling you’re the only one who’s wide awake and the rest of the country is resting soundly?
You are not alone; one in 5 people are said to have difficulty sleeping. Sleep is absolutely essential for basic maintenance and repair of the immune, musculoskeletal, neurological, endocrine and digestive systems.

Areas lack of sleep will impact
|
| Cognitive decline: The ability to think clearly & function well is negatively impacted |
Impaired immune system |
| Mood & Mental health: Insomnia is linked with depression/anxiety |
Overweight and Obesity: High levels of the stress hormones from sleep deprivation drives down carb intolerance & sugar isn’t removed from the blood. If this remains persistent – it could lead to insulin resistance and increase levels of fat. |
| Inflammation: Can lead to chronic low grade inflammation. |

Eat Right – Sleep Tight
Supporting your brain and body throughout the day with good nutrition is essential for good sleep. The basic principles are to eat regularly, eat at each meal, good fats, protein and slow releasing carbohydrate sources to help maintain mood, blood sugar levels and help your body carry out day to day functions.
A varied diet that contains the B vitamins and calcium is also a requirement to help the brain use the tryptophan to manufacture melatonin so eat foods rich in these, bananas, cabbage, walnuts, fish, and so on.
Tryptophan – What is it?
Stay with me on this one – I will try and avoid the science….
Tryptophan is a precursor of the sleep inducing substances serotonin and melatonin. The brain uses Tryptophan to build these relaxing neurotransmitters.

Foods that contain Tryptophan
|
| Turkey/Chicken/Venison |
Liver |
| Eggs |
Cheese/Gruyere/Cheddar |
| Salmon/Seafood/Cod |
Sunflower & Pumpkin Seeds/ Nuts |
| Bananas |
Spinach |
Eat Tryptophan containing foods & you will raise serotonin
We read it all the time – gobble up Tryptophan foods and you will increase serotonin and therefore conversion into melatonin and BOOM! – We should sleep – Has that worked for anyone?
NO – It is not backed by research
The body is not as simple as this common statement would have us believe – ‘Eating foods rich in Tryptophan will not raise brain serotonin’ and here is why:
- Tryptophan is the least abundant amino acid in protein.
- After eating a meal containing protein, there is a rise in several amino acids and they compete for a transport system to cross the blood-brain barrier. Being as Tryptophan is the least abundant it loses out on this battle.
However-
- Eating carbohydrate foods with Tryptophan containing foods makes this amino acid more available to the brain.
- A high carbohydrate meal stimulates the release of insulin, which helps lower the levels of blood amino acids except for tryptophan which therefore allows more of this sleep inducing amino acid to enter the brain and manufacture serotonin and melatonin.
Melatonin: What is it?
- A natural occurring hormone that regulates sleepiness. It is released at night by the pineal gland at night to induce and maintain sleep.
- It is made in the brain from Tryptophan , first converted into serotonin , then finally melatonin
- Foods rich in melatonin are almonds, Montmorency cherries and bananas.
Eating for sleep – Worth Considering? 
I am not suggesting eating correctly is the winning formula to help sleep – but if you are stuck in the vicious insomnia cycle – it makes sense to focus on your diet as it may well impact your sleep in a positive way and give you some quality ‘Shut Eye’
- The research is suggesting 3-4 hours before bed you should take on board some carbohydrates with your evening meal. Choose your carbohydrate choices wisely- avoiding the sugary processed kinds in favour of sweet potatoes, brown rice and oats.
- Sweet potato with salmon and spinach
- Chicken stir-fry cooked with brown rice
- Homemade venison burgers with slices of Gruyere Cheese with some sweet potato
- Oat cakes with a banana (snack before bed)
- Bowl of Total Greek 0% yoghurt with some nuts, seeds and half a banana (snack)
Areas being researched 
- Valerian Tea: This herb can bring on a restful sleep without morning sleepiness or other side effects. It is useful for insomnia, anxiety and tension. Studies are showing that valerian can aid people who have difficulty in falling asleep. I have tied this tea and find it calms me at night.
- Cherry Juice: Studies have shown that people who drank Montmorency cherry juice received a significant boost to their levels of melatonin, the hormone that regulates sleep and on average their total sleep time increased by 25 minutes. The current trials are testing a serving am and pm for the affects to take place.
- Glycine: This amino acid (found in meat and fish) has a calming effect on the brain and research suggests that glycine may help promote deeper sleep. This was observed at 3grams per day. It is said to increase sleep duration and quality and decrease the time taken to fall asleep.
