Alkaline foods include: beans (with pods or green beans), vegetables, fruits (except bananas, plums, processed fruits), fresh milk, cereals (such as corn), tea, kelp, seaweed, yeast, iodine, calcium, vitamin D.
2. Summer or high temperature environment
Studies have shown that the temperature of the environment a month before sex is an important factor affecting the sex of a baby.
