Christmas is a distant memory. For some of us, the annual mission undertaken by chocolate, mince pies, brandy butter and yule log to convert themselves into excess body fat has been a success. Once again we find ourselves in post-yuletide gloom, with weight to lose and fitness to gain.
We all know that New Year resolutions are made to be broken. As the fireworks break out and we blow up what is definitely our last supersized bag of crisps of the season with a salty bang, it’s all too easy to go online and sign up to membership of the local gym. It’s also not that difficult to declare that alcohol will not touch our lips for the foreseeable future and filling up our supermarket trolleys with healthy stuff, including items disregarded in the approach to Christmas (and possibly at most other times of the year too), such as celery and low fat cottage cheese, requires little in the way of moral fibre when we’re still feeling bloated and slightly nauseous due to our recent excesses.

Heavy metals are natural components of the earth’s crust; however, certain activities of mankind, such as mining and smelting, have led to them becoming concentrated in the environment, in some areas reaching potentially harmful levels. Other sources such as vehicle emissions, industrial waste and fertilizers also contribute to the accumulation of heavy metals in the soil, atmosphere and surface water.
Heavy metals can be severely detrimental to the human body, having toxic and carcinogenic effects and causing the oxidative deterioration of biological macromolecules. The various metals have been implicated in the development of many diseases, including Alzheimer’s disease, diabetes and several forms of cancer.

From improving cognitive performance to reducing the risk of cardiovascular disease, the purported health benefits of omega-3 fatty acids have been well documented in recent years. As consumers become more aware of the health benefits they have to offer, the pressure is on to find a sustainable source of these fatty acids to meet the ever-increasing demand.

There are many other factors that affect success in weight-lifting, but adequate protein intake is crucial. Protein contains amino acids, which the body uses for repair and growth. If you don't consume enough protein, your body won't have enough materials with which to rebuild your muscle tissue after intense workouts.
Recommended levels of protein vary, but a widely-promoted rule is that of consuming at least 2g of protein per kg of body weight.
So just eat plenty of protein, like chicken, right? Not quite. Total calorie intake is also important and not all chickens are the same...
Many people, particularly those concerned with weight loss or heart disease, are fearful of fats. Low fat diets – which cut down drastically on all types of fat regularly eaten – run a risk of creating the condition for mental distress.
Fats are very important with regard to emotional and mental health, with low levels in the diet being associated with symptoms that range from anxiety and depression to hyperactivity and schizophrenia. Furthermore, in an editorial in The British Journal of Psychiatry, Malcolm Garland explained:
‘...the essential fatty acids (EFAs) are LC-PUFAs obtained exclusively through diet…comprise 15–30% of the brain’s dry weight.’
