Good nutrition keeps all vessels flexible, and plaque-free, and liquids running fluently. High hemoglobin (thick blood) and high cholesterol levels also weaken the circulation into the genitalia. Junk food and processed food are the worst.
A diet rich in fiber (about 100 g/day), cold-pressed Omega-3 oils, vegetables, berries, fruit, and whole grain products are beneficial. Natural compounds that support erectile functions can be found in nuts, pollen, and seeds. Tomato and cabbages are known to prevent prostate problems. Green tea and pomegranate prevent prostate cancer.
Hormone researchers have found out that chemical residue from the fields (herbicides and pesticides) alone, or in conjunction with compounds of certain plastics (phthalates, DPA), may cause hormonal imbalance (disturbed production of testosterone) in males as early as in the fetal stage. This is also found to be one reason behind the reduced quality of sperm and testicular diseases. Smart men store their food in ceramic cans and eat organic food. Also, the use of cosmetics or any chemicals during pregnancy increases the risks of hormone disruption in fetuses.
There are several so-called superfoods, some of which have been proven to increase one’s libido. These are, for example, dark chocolate, pollen, ashwagandha, goji berries, maca, and some other tropical fruit and berries.
Good and healthy food with fiber content higher than 50 g/day, results in better intestine activity, which in turn, keeps the diameter of the rectum smaller. An enlarged rectum from lack of fiber presses the bladder and the prostate, thus increasing known health risks. In such conditions, the inner surface (epidermis) of the rectum and colon are also often damaged which means leaking of toxic biochemicals from the intestine into the tissues outside.
Modern common nutrition is unavoidably insufficient since most of the food comes from depleted fields or artificial and poor growing environments (greenhouses). The normal daily intake of nutrients from food is generally well under the optimum (the minimum or “recommended” levels are a completely different matter).
An optimum nutrition level is very helpful. One can achieve that by taking a broad-spectrum multivitamin and mineral capsule twice a day. Men should have their vitamin D level over 120–150 nmol/l (need to take 100–150 mcg /day), and take vitamin E at least 50 mg, vitamin C 3 x 1 g, magnesium (Mg) 600 mg, zinc (Zn) 15 mg, copper 1-2 mg, selenium (Se) 200 mcg, and strong multi-B vitamins including 1 mg of B12 to be melted in the mouth.
On days when one is not eating fish, it is wise to take 3-4 g Omega-3 in fish oil capsules. In the long run, this will keep the heart, brain, joints, veins, and arteries in better condition all over the body and prevent several problems and inflammation.
Guarana (Paullinia cupana) from Brazilian rain forests and Muira puama (Ptychopetalum olacoides = virility tree) are known to be good for erectile problems, and liquid shark fin extract is known to have a preventive effect on prostate cancer.
Supplement critics should think about why all breeding stallions (and other livestock as well) are given a fair vitamin-mineral portion every day. The normal food is just not good enough.
