What are EFA’s?
These are fats that are essential to the body’s optimum functioning. They cannot be made by the body so must be obtained from the food we eat.
The main EFA’s are:
• Omega-3
• Omega-6
• Omega-9 (non-essential as the body can make some as long as it has plenty of Omega 3 & 6).
Why do we need EFA’s?
They have a large number of roles within the body, including:
• They generate and maintain the fatty membranes which surround every body cell.
• They are important for memory and brain function.
• They help maintain healthy hair, skin and nails.
• They are essential for maintaining a healthy hormone balance, good eyesight and a strong immune system.
• They offer protection against heart disease by helping to reduce cholesterol and triglycerides. They increase the ‘good’ HDL cholesterol and decrease the ‘bad’ LDL cholesterol.
• They can be converted into prostaglandins which help transmit important information vital for controlling inflammatory reactions and activity of the immune cells.

Patterns of behaviour and brain function are largely influenced by diet.
There is increasing evidence to suggest t hat poor diet can lead to poor behaviour and learning disabilities amongst children.
The most common problems arising today include:
• ADHD
• Hyperactivity
• Autism
• Dyslexia
Not only do these have a negative impact on the individual’s personal development, they also cause a disturbance in family life, the classroom and society at large.
ADHD/HYPERACTIVITY
Characterised by 3 major problems:
• Lack of attention
• Hyperactivity
• Act on impulse
It is estimated that five percent of school aged children in England and Wales have ADHD. This is the equivalent of three hundred and sixty seven thousand.
This means that in an average class of thirty children, one or two will present with ADHD.
The incidence amongst boys is greater than girls.

People who are sensitive to sugar almost always have low levels of the neurotransmitters seretonin and beta endorphins. Serotonin helps to regulate mood, impulse control and appetite and so low levels can lead to compulsive tendencies, depression and irritability and creates a biochemical disposition towards sugar addiction.
The consumption of sugar evokes beta-endorphins, which are natural painkillers and that can create a sense of euphoria. They also determine pain tolerance, self esteem and confidence in individuals. So the sugar sensitive person gets an actual high when they ave something sweet and will often find it impossible to stop at one biscuit; they have to have the whole packet.

With the rising obesity epidemic, increasingly large numbers of people are spending huge amounts of money on so called “health” products that advertise themselves as aiding weight loss. In reality they are proving to be ineffective
A new EU Directive on Unfair Commercial Practices has been adopted this year in the UK and it is hoped it will help prevent consumers spending money on these useless food products in an attempt to prevent their disease. Although it is illegal for unsubstantiated claims to be made on the nutritional functions of food products, many benefits are still implied through use of brand names and packaging images even with no evidence.
Consumers are easily tempted to part with huge amounts of money in an attempt to help curb their problem. It is hoped (Lean 2008) that this new EU directive will put a halt to this practice.

Professor Brian Lieberman from Manchester Fertility Services has recently highlighted the risks to a woman’s fertility by following the latest trend to become a ‘size 0’ in an attempt to mimic celebrities who are exceptionally thin.
Women with a body mass index (BMI) of less than 19 are at risk of irregular or absent periods which can result in infertility as ovulation ceases. In addition it can also lead to osteoporosis. A certain amount of body fat is required to store and produce oestrogen, essential for fertility.
This is reversible with adequate weight gain to achieve a healthy BMI of 19-25.

Obesity is a major health problem in the 21st
century both across the UK and worldwide. It is defined as a body mass index equal to or over 30kg/m2 (Health Survey for England 2006).
According to the government’s foresight report
(2007), by the year 2050 sixty percent of men and fifty percent of women in the UK could be obese due to ‘passive obesity’ – a state in which the effects of
modern living overpower biological control of body weight. The result is that
every generation becomes heavier than the previous one.

A research study
published last week reports that forty percent, of over a thousand people who
had their liver function tested showed high levels of enzymes, known to be an
indicator of increased liver failure leading to death.With liver
failure, symptoms only appear once significant liver damage has occurred and
cannot be reversed.
Liver disease is
the fifth largest killer in the UK and still on the increase. It is responsible for seven thousand five hundred deaths
per year but is also almost completely preventable.
