Good nutritional habits promote overall health of our skin.
Breakfast:  
Eggs, frittata, organic peanut butter, almond butter, cashew butter, rolled oats (not quick cooking oats), quinoa,  avocados, wholegrain bread that is not mass produced and full of preservatives, rye bread, a healthy muesli that is not mass produced and full of sugar, fruit salad, nuts (unless allergic), white cheese (but only occasionally), seeds such as pumpkin, sesame, sunflower, chia etc, juicing (especially carrots that are rich on Vit A and good for the skin), coconuts (fresh or coconut water), organic cocoa, rooibos tea, Replace sugar with raw honey, or xylitol.  
Lunch and dinner:

Keep your intake of carbohydrates low and protein high with as much fresh fruit and vegetables as possible.
Include cold pressed oils in your diet such as Flaxseed/linseed, avocado, olive, grapeseed, coconut etc. Drink plenty of water to help the skin flush toxins and allow the kidneys to effectively eliminate these toxins. Add ginger, turmeric and cinnamon spices to your diet.
AVOID:  
Processed/refined man-made foods - cereals, takeaways, pastries, sugar, dairy - unless organic and unpasteurized, fried foods, dairy (The culprit is hormones used to encourage growth in cows) fizzy drinks, fruit juices unless freshly squeezed, pasta (unless gluten free), processed meats such as ham and polony, alcohol, coffee, energy drinks, yellow cheese.
The more processed high carbohydrate foods we eat the higher our insulin and acid levels become. Increased insulin causes an increase in the production of the hormone androgen which causes a break out of acne. High acid levels disrupt enzyme function and increase inflammation of the skin.  
Acne occurs when a mixture of oil and dead skin cells form a plug that blocks the skin's hair follicles and pores. Though blocked, the gland keeps pumping out oil, providing a perfect breeding ground for bacteria. The resulting inflammation causes redness, swelling and tenderness of the surrounding skin.
"Eskimos only developed acne for the first time when they adopted a Western diet of highly processed (Fast Foods) and refined foods."
