Nutrition for tight foreskin (plus get sunlight)

In order for your body to function at maximum capacity it must have the right nutrients.  many people's bodies are functioning at half-power due to lack of all essential vitamins and minerals the body needs.

Good foods to eat:

I would say omega 3 fatty acids are good for growth.  It is certainly something most people are deficient in.  So, Fish.  You can get sardines and mackeral in cans quite cheaply.  They are usually in tomato sauce or sunflower oil.  Red salmon cans too. Flaxseed is a good snackfood.

Avocado also contains essential fatty acids.  They are a very good superfood.  I instantly feel a positive effect after eating an avocado.
Soups are another quick tasty way to get nutrients.

Smoothies.  I personally use a machine called the nutribullet.  It is very good and simple to use.  Look on amazon.  A typical smoothie would be: half kale or spinach leaves. a banana, handful of blueberries, some flaxseed, then fill with water or coconut milk.  Maybe add some raw beetroot too (which you can get in the fruit and veg section at big supermarkets -such as sainsburys or tesco in uk).  Beetroot is good for improving blood flow.  Watermelon is also good for improving blood flow.  Ginkgo biloba tablets are also good for bloodflow.  

Make sure you drink enough water.  your pee should never be yellow.  If it is you know your body needs more.

Also make sure you expose as much skin to sunlight from April to September.  Your body produces vitamin D through your skin being exposed to sunlight.  But this can only occur during summer months as in winter months the sunlight isnt as strong.
