Eating and Ovulation
Processed foods and refined carbohydrates, aside from messing with your hormones, also take up valuable space in your diet that could be going to more nutrient-dense foods. Making up the difference with multivitamins can help but nutrients gotten this way are rarely absorbed as well or completely, often leaving people deficient.
Even people who eat a lot of vegetables but choose mainly conventional produce over organic can end up falling short of their nutritional needs - because of modern farming practices, a lot of conventionally grown food has a fraction of the amount of nutrition that organically grown produce has. In addition, conventional produce often contains pesticides and herbicides that can directly interrupt fertility.
Just like egg cells, sperm and highly vulnerable to oxidative stress, and just like eggs, sperm quality tends to improve with an anti-inflammatory diet that's high in diverse antioxidants. Certain nutrients seem to be especially helpful for sperm quality - vitamin E, for example, which is high in many nuts and seeds, has been shown to be protective for sperm health and motility.
All of these hormones are affected, either directly or indirectly, by what you eat. High carbohydrate diets, especially diets with lots of refined sugar, can increase insulin and leptin levels, causing your body to become “resistant” to these hormones. This is like a child who’s mother has called their name too many times and they’ve become “selectively deaf-” your body’s insulin and leptin levels have been up for so long that your body is starting to tune them out.
Thyroid hormone levels can also be strongly affected by what you eat. Food allergies and sensitivities, in addition to certain mineral and vitamin deficiencies, can lead to lower levels of thyroid hormone. This can cause problems with ovulation and even increase miscarriage risk.
