IF YOU EAT FISH YOU WILL BE A PATIENT



Generally eating fish is not harmful to us but nowadays eating fish is harmful to us because of the water pollution. Consuming fish from polluted water give you lot of health risk.I can mention Some of them Heavy metal like mercury lead and cadmium can be enter our body,Some chemical waste that release to the water by some industries,Micro Plastic some agricultural waste and many more

Now we discuss about this thing one by one 

Firstly I consider  about heavy metal Heavy metals are metallic element with  high atomic weight and density.this metal can be found in soil water and air.Some of them are essential trace element for living organism.in small amount.Higher concentration can be toxic and harmful to human and other living organism.most common heavy metal are

 Mercury(Hg),Lead(Pb),Cadmium(Cd),Arsenic(As),Chromium(Cr) and Nickel(Ni)

Mercury can be release into water bodies from Industrial process  coal combustion   and natural source.It can accumulate in fish.If man eat fish that accumulated Mercury.This heavy metal affect our central nervous system and respiratory system and damage our kidney.Some studies said mercury can affect our heart also.

Lead is often present in water due to lead base paint plumbing materials and industrial discharge to the water bodies.Lead is affected our health.Lead can damage our nervous system.Lead can lead to learning disabilities  lower IQ and attention deficit disorder to children.Memory concentration and decision making problem can be lead to adult. Development delay and neurological damage can be seen in unborn children if their mother affect by lead.Lead can interfere with production of hemoglobin damage kidney and decrease fertility.

Cadmium can affect our respiratory system reproductive system and immune system.Cadmium increase risk of lung cancer reduce fertility of male and many more

Unlike other animal fish can get nutrition through osmosis so heavy metal can easily enter fish's body through their skin by osmosis.

Some chemical waste that release from industries added to the water bodies.this chemicals come into the fish's bodies.Some agricultural waste like chemical fertilizer and insecticide pesticide also enter to fish's bodies.After eating fish this chemical come to our bodies.this chemical increase risk of liver cancer and damage kidney and many negative health  problem. 

Now we consider about plastic and polythene.This materials enter the sea. they can persist for year without degrading.Some fish eat this polythene and plastic as food so fish have to face many health problem.Plastic and polythene can release harmful chemical into water.Some of these chemical are toxic.They can bio accumulate in the food chain.This harmful chemical finally enter our body If  we eat fish.This chemical increase risk of cancer and damage our kidney.

The plastic and polythene waste that release into the break down into smaller particle that called  micro plastic.This micro plastic can bio accumulate in food chain.As I mention before this micro plastic also come into our body if we eat fish. 

Eating fish without cooking can infect some disease like listeria.This infection can be infect if you cook fish low temperature Some people eat fish as smoked fish.Smoking can not kill this bacteria.

Above mentioned health negative health effects are related to the water pollution.but there are some negative health effect that not related to water pollution.I can describe some of them.

Eating fish increase risk of urinary stone.because fish are calcium rich food.we need small amount of calcium but excess amount can harmful to us.Small fish have more calcium than large fish.   

Fish is rich of heme iron so eating fish can increase risk of cardiovascular disease.Large fish have more heme iron than small fish. 

Excess  amount of salt is used to make dry fish so eating dry fish increase risk of cardiovascular disease. 

Formalin (CH2O) is used as preservative for fish.This organic chemical is carcinogens.         .

CARBOHYDRATES

  Carbohydrates are the most common organic compound in the world. Carbohydrates are produced by green plants and photosynthetic microorganisms. The process of producing carbohydrates is called photosynthesis. It uses water (H2O) and carbon dioxide (CO2) to produce carbohydrates in the chlorophyll with the help of solar energy. Oxygen  gas is produced also 6CO2+6H2O = 6C12H6O+6O2 Carbohydrates can be divided into three groups.They are monosaccharides, disaccharides and polysaccharides. Monosaccharides can again be divided into three groups. They are glucose, fructose and galactose. Although the chemical composition of these three monosaccharides is the same, there are slight differences in the bonds between the atoms. Ripe fruits and honey contain glucose. In the digestive system, glucose easily accumulates in the bloodstream. Fructose is the most common in ripe fruits. Therefore, it is also called fruit sugar. Unlike glucose, fructose is absorbed by the body very slowly. Most...

MOST COMMON CARCINOGENIC FOOD

Image
  The relationship between diet and cancer risk is complex and depends not only on specific foods but also on overall dietary patterns and lifestyle factors. However, certain foods and cooking methods have been linked to an increased risk of cancer. 1.Processed meats  such as bacon, sausage, hot dogs and deli meats. These often contain nitrites and nitrates, which when cooked or metabolized form carcinogenic compounds called nitrosamines. 2. Charcoalized meat  Grilling or frying meat at high temperatures leads to the formation of heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which are known to be carcinogenic. 3. Red meat The meat of mammals like cow, goat, sheep and pork belong to this category. Various carcinogens are produced during the cooking process of these types of meat. It has been confirmed by scientific research that cancers related to the colon, rectum and prostate gland  are caused by red meat. 4.Alcohol Excessive alcohol consum...

NEGATIVE HEALTH EFFECT OF EATING CHICKEN

Image
  There are many negative health effect of eating Chicken.I will consider some of them.Chicken is source of saturated fat and cholesterol.Chicken can have carcinogenics.Use antibiotic Some Infection can come with chicken. Chicken have much saturated fat like other red meat.This saturated fat can easily convert to cholesterol.  Chicken is cholesterol rich food like other red meat.Cholesterol can block our arteries and effect our heart  High cholesterol level can indirectly contribute to sexual dysfunction. Chicken can have carcinogenics like Aflatoxins. This toxin is contain in some grain like corn soya bean.  This grain are used as food for broiler so Aflatoxins are accumulated in fowl's body.when we eat chicken these toxin enters our body.   Some processed chicken like sausages nuggets and deli meat can have additives preservatives harmful chemical some carcinogens and high level of salt. Antibiotics are used for prevent disease.This antibiotic can release to e...
