How does environmental factors affect obesity?
Environmental factors like high fat foods, super-sized portions, fast food consumption play a major role in occurrence of obesity. Individuals are addicted to high fat and calorie, highly palatable and inexpensive foods. Behaviour is one of the factors influencing weight gain.
What are the effects of environmental contaminants?
The impact These pollutants can be consumed or absorbed by fish and wildlife, which in turn may be eaten by us. Chemicals can also get into sediments, impacting large coastal areas, threatening human health, and reducing the economic well being of regions that depend on a healthy coastal environment.
What are environmental mutagens?
Environmental mutagens are defined as chemical and physical agents in the environment that induce genetic mutations or increase mutation rates during the human life span [1].
What is the cause and effect of obesity?
Obesity is generally caused by eating too much and moving too little. If you consume high amounts of energy, particularly fat and sugars, but do not burn off the energy through exercise and physical activity, much of the surplus energy will be stored by the body as fat.
What are the effects of contaminants?
Some pesticides have the potential to harm humans, wildlife, and native plants if they are exposed to high enough levels for a long enough period of time. Depending on the chemical and concentrations, possible health effects include cancer, reproductive or nervous-system disorders, and acute toxicity.
What are some examples of environmental contaminants?
Environmental Contaminants
- Lead.
- Arsenic.
- Bromate.
- Brominated Flame Retardants.
- Chlorinated Naphthalenes.
- Dioxins and Furans.
- Mercury.
- PCBs.
What are examples of environmental mutagens?
Various mutagens, which pollute air, water, and food, possibly induce mutations in humans, and are suspected of causing cancer. Environmental mutagens, such as polycyclic aromatic hydrocarbons (PAH) and heterocyclic amines are known to bind to nucleotides, resulting in the formation of DNA adducts.
What do mutagenic pollutants do that harm living species?
They can affect the transcription and replication of the DNA, which in severe cases can lead to cell death. The mutagen produces mutations in the DNA, and deleterious mutation can result in aberrant, impaired or loss of function for a particular gene, and accumulation of mutations may lead to cancer.
Who does obesity affect?
Obesity affects some groups more than others The obesity prevalence was 40.0% among adults aged 20 to 39 years, 44.8% among adults aged 40 to 59 years, and 42.8% among adults aged 60 and older.
What is the effects of obesity?
Being overweight or obese can have a serious impact on health. Carrying extra fat leads to serious health consequences such as cardiovascular disease (mainly heart disease and stroke), type 2 diabetes, musculoskeletal disorders like osteoarthritis, and some cancers (endometrial, breast and colon).
