Give any one example of how diet may influence the outcome of a set of inherited traits or a genetic ...

Answer to #1

Studies that look at how a gene's (DNA that encodes for a trait) expression may be controlled by the environment. DNA can have methyl groups attached to the molecule which make it more difficult for RNA and then protein to be made from that gene. This would result in a reduced level of gene expression. Certain vitamins such as folate may play a role in reducing gene expression by increasing the level of methylation of DNA. If a gene for cell division (growth) is more heavily methylated, the gene will not be expressed and cell growth will be reduced. This may help reduce the risk for abnormal cell growth that is seen in cancer formation. People are encouraged to eat more fruits and vegetables that contain folate as well as other nutrients. Many more studies are needed establish this link between folate intake and cancer risk reduction.

Answer to #3

People can reduce the amount of a pre-packaged food that they eat at a sitting. They could also decrease the frequency at which they have such a food. It is thought that 2 mg of mineral oil could leak into a serving of 100 grams of rice. This is not harmful in itself but over time, the oils could accumulate. If people are aware of this potential danger, they can make conscious choices to reduce their exposure to mineral oils until the food packaging experts develop an alternative to using recycled cardboard with mineral oil containing inks.

Answer to #5

Polyethylene terephthalate (PET) has been shown to not allow mineral oils to migrate into foods very easily. This result came from the lab in Zurich that was shown in this video. Food packaging manufacturers are aware of this mineral oil migration problem and will have to develop alternative packaging or develop inks that do not contain toxic mineral oils.

Answer to #7

People can utilize variety in their diets. They can select fresh, frozen, or canned starchy foods in place of pre-packaged starchy foods. For example, if someone eats rice on a regular basis, they could substitute rice with freshly cooked potatoes which do not have exposure to mineral oils in food packaging. Also, foods with a higher level of fat may absorb more mineral oils than their lower fat counterparts.
