High cholesterol: Eating tuna could inadvertently be increasing cholesterol levels


“All humans are exposed to some level of mercury,” testified the WHO, however growing foetuses are most susceptible to developmental effects.

In short, this is why women trying for a baby, and those who are pregnant, are advised against eating shellfish and too much oily fish.

Methylmercury is “toxic” to the central and peripheral nervous systems; symptoms include:

  • Tremors
  • Insomnia
  • Memory loss
  • Neuromuscular effects
  • Headaches
  • Cognitive or motor dysfunction

Scientific research also highlighted that people also had 56 percent greater odds of having higher total cholesterol if they had high levels of lead in the blood.

“Lead in drinking water mostly occurs as a result of old lead plumbing,” the organisation elaborated.

Smoking and second-hand smoke are also sources of lead exposure in the UK.

Exposure to high levels of lead can lead to:

  • Stomach upset
  • Mood changes
  • Poor attention span
  • Headaches
  • Hallucinations
  • Brain damage
  • Kidney damage

“Eating food or drink or breathing in air contaminated with lead or lead compounds for a short period usually does not cause any ill effects,” reassured PHE.
