No technique or method is fool proof when it comes to influencing the gender of your baby. At best, the techniques and methods can make a slight difference, but ultimately mother nature has the final say. However if you can align the techniques in a concerted manner then the influence you have over baby gender may be increased further. With this in mind, here is one technique that might help you. It concerns the types of food you should eat if you want to conceive a boy.  

The type of foods you eat applies to the woman (as opposed to the man) and it applies to before conception, rather than after conception. Once the baby is conceived, it's sex is already determined. So the reason to eat certain types of foods is to benefit the male sperm as this is the decisive factor in determining the sex of the baby.

Sperm that makes the baby male are thought to be fast moving but have a shorter lifespan. By altering the PH level within the vagina, you can increase the lifespan of the boy creating sperm. You want to make the PH level more alkaline and this can be done by eating certain foods.

Foods that make your body more alkaline include things like fresh vegetables.

So try to eat things like :

Peas Carrots Lettuce Beetroot Celery Cauliflower Cabbage Spinach Green Beans 

Of course you should be careful how you prepare such foods. Many people like to eat pickled beetroot but it is generally very acidic as vinegar is used to pickle it.

You can also eat most nuts and grains, such as lentils, almonds and pumpkin seeds.

Avoiding certain foods that make your body more acidic can also be helpful. So avoid things like sweet treats, fizzy drinks and candy bars.

You should also limit your intake of dairy products and meats.
