Refined carbohydrates and sugar or comfort foods result in a quick sugar rush rather than sustained energy levels.
Eating refined carbohydrates (white varieties of bread, pasta, rice or flour) and sugar leads to a surge in insulin and an insulin-like growth factor called IGF-1.
This can also influence sebum production in the skin and result in skin cells dying quicker.
Oil and dead skin cells block pores, which can lead to acne breakouts in acne-prone individuals.
Too much caffeine will dehydrate the body and lead to dry skin.
Caffeine also increases the release of the body's stress hormones which can have a negative effect on the skin and exacerbate existing skin problems, such as acne.
Although lean red meat is an excellent source of protein, iron and other important nutrients, processed red meat is also high in saturated fat so these products should be avoided.
The latter can be inflammatory and enhance skin problems such as psoriasis and acne due to the meat being more acidifying and having a negative effect on pH balance.
Cigarettes and alcohol both contain high levels of toxins, which your liver has to work hard to get rid of.
This may also encourage oil production on the skin as it tries to help the body release these extra toxins, resulting in spots which can then lead to acne breakouts if your skin is prone.
Ideas for natural acne treatment: Some small but simple changes to your lifestyle could in fact help to resolve acne issues.
Here are some suggestions for healthy happier skin: H2O Ensuring sufficient fluid intake is important for the skin to remain hydrated.

Milk protein lactoferrin It may come as a surprise but a milk protein called lactoferrin has actually been found to help reduce the development of bacteria responsible for many skin impurities and can help prevent blemishes and spots forming due to its antimicrobial effect.
This bacteria cannot be found in everyday diary products, however some supplements for acne-prone skin incorporate praventin which is rich in lactoferrin and has been clinically proven to improve skin after just eight weeks.
Vitamin B complex Helping the body release energy, B vitamins all have important roles to play in our health.
Certain B-vitamins such as biotin are needed for maintenance of healthy skin, mucous membranes, which protect the body on the inside and nails.
Vitamin B6 in particular plays a key role in protein and glycogen metabolism which can impact on skin health.
This vitamin also plays a role in the normal regulation of hormonal activity, which might be of benefit for those prone to cyclical spot outbreaks and acne.
B-vitamins are found in oily fish, meat, eggs, soya beans, whole grains, wheatgerm, fortified breakfast cereals and dried beans.
Essential fatty acids Essential fatty acids are the 'good fats' that are vital for our all round health, including our skin.
Not only do they maintain the skin's moisture barrier for a smooth, glowing complexion but they are also important for regulating the body's inflammatory processes, helping with dry, irritated skin and eczema.
As essential fats cannot be produced in the body, they must be obtained through diet and can be found in foods such as oily fish, nuts and seeds.
Vitamin C Known for its healing and antioxidant properties, this vitamin plays a very important role in skin care but can be depleted from the body by stress, too much sun exposure and consumption of harmful chemicals (smoking, drugs and alcohol, which can be linked to acne break outs).
It is also essential in the production of collagen.
Good sources are tomatoes, parsley, peas, peppers, Brussel sprouts, sweet potatoes, oranges and kiwi fruit.
