Experts used to think that erectile dysfunction was predominantly caused by psychological or neurological problems and whilst that’s true for some men, evidence now clearly suggests that for the vast majority, the issue is worsening blood vessel function. It’s affected by the same risk factors as heart disease and it can be its first indicator. High blood pressure, obesity and smoking markedly increase the risk of both heart disease and erectile dysfunction.

Growing mountain of evidence is in agreement that soya is safe and nutritious
A new review of all scientific studies and data on the safety of soya has been conducted to settle the debate about whether soya has positive or negative health effects. The authors focused particularly on the health of different population groups, such as vegetarians and vegans, children and cancer patients.
Early onset of menarche (the first period) may negatively influence the future health of women – in particular, it has been linked to an increased risk of hormone-related cancers such as ovarian and breast. Some types of food have been implicated (meat, milk, animal protein and fats in general) and to clarify whether soya can play a role, a team of scientists examined this in a high soya-consuming population.
Dangerous environmental pollutants called polychlorinated biphenyls (PCBs) were the first industrial compounds to experience a worldwide ban on production more than 30 years ago because of their potent toxicity. However, they are very persistent and therefore still present in our environment. Once in the body, PCBs accumulate in the fat tissue and can cause long-term problems such as reduced infection fighting ability, mental and behavioural problems, decreased activity of the thyroid, reproductive problems, can induce cancer and severely damage the development of a baby.
Soya foods contain phytoestrogens, including isoflavones, which have weak oestrogen-like qualities. Because of this, some people think soya foods can affect male fertility. However, there is no scientific evidence to support this notion. A recent review of all the available research shows that neither soya foods, nor isoflavone supplements from soya, affect testosterone levels in men. This research adds to the large body of evidence supporting the role of soya as part of a healthy veggie diet.
Scientists in Spain have revealed how meat and dairy foods may be linked to fertility problems. This study found that men who ate the most meat and full-fat dairy products had fewer and slower sperm, while those who ate the most fruit and vegetables had higher quality sperm that swam faster. Lead researcher Professor Jaime Mendiola said “…among the couples with fertility problems coming to the clinics, men with good semen quality ate more vegetables and fruit, which means more vitamins, folic acid and fibre and fewer proteins and fats, than those with poor sperm quality”.
