Starvation effects pass on to next 3 generations

Starvation effects pass on to next 3 generations

Starvation may affect the health of at least the next three generations, says a study.

“Events like the Dutch famine of World War II have compelled scientists to take a fresh look at acquired inheritance,” said Oliver Hobert from the Columbia University Medical Centre in the US.

Starving women who gave birth during the famine had children who were unusually susceptible to obesity and other metabolic disorders, as were their grandchildren.

Starvation induces changes in the cell structure, specifically in the RNAs (Ribonucleic acid) and these changes are passed on for at least three generations, the findings showed.

The research team starved roundworms for six days and then examined their cells for molecular changes.

The starved roundworms were found to have a specific set of small RNAs which persisted for at least three generations, even though the worms were fed normal diet.

The researchers also found that these small RNAs target genes with roles in nutrition.

The study was published in the journal Cell.

Thinking too much about food could make us eat more

A new analysis of 50 studies has found that thinking before eating may actually undermine people’s dieting goals.

Jessie De Witt Huberts of Utrecht University says that we are expert rationalizers when it comes to finding a reason to eat more. He said that people seem to

be very creative in coming up with such reasons, asserting that they can justify having the cake on account that it has been a hard day, or that they will exercise tomorrow, that it is a special occasion, or that it is impolite to refuse.

Huberts said that this is when justification processes become a slippery slope – as the reasons are often applied ad hoc, they no longer form strict rules that regulate when you stick to your diet and when you can cut yourself some slack.

A growing body of research has found that such justification can even come from performing well on a task or from doing good for others. In several studies, people who received positive feedback on a task were more likely to choose an unhealthy versus a healthy option.
