Is this really me? Parasites and other humans’ cells in our brains change our psychology

Many people are suspicious about being manipulated in their emotions, thoughts or behaviour by external influences, may those be drugs or advertising. However, it seems that – unbeknown to most of us – within our own bodies exist a considerable number of foreign entities. These entities can change our psychology to a surprisingly large degree. And they pursue their own interests – which do not necessarily coincide with ours.

Guest Post: Why isn’t the world going vegan?

Written by Catia Faria

Universitat Pompeu Fabra

Last month, the Academy of Nutrition and Dietetics, one of the world’s most influential organizations in its field, published an updated version of a paper concluding that animal-free diets are absolutely healthy (Cullum-Dugan & Pawlak 2015). The article presents the official position of the Academy on this topic, according to which, when well designed, vegetarian and vegan diets provide adequate nutrition for all stages of the life cycle, including pregnancy, lactation, infancy, childhood and adolescence.

 It would be reasonable to expect that such conclusion had a significant impact on people’s dietary choices. If adopting a vegan diet imposed great costs on the health of human beings, then doing it might not be what we are required to do. Yet the health argument has been, again, debunked. So, why aren’t people going massively vegan? Continue reading

Strange brew: opiates from yeast

A recent series of papers have constructed a biochemical pathway that allows yeast to produce opiates. It is not quite a sugar-to-heroin home brew yet, but putting together the pieces looks fairly doable in the very near term. I think I called the news almost exactly five years ago on this blog.

People, including the involved researchers, are concerned and think regulation is needed. It is an interesting case of dual-use biotechnology. While making opiates may be somewhat less frightening than making pathogens, it is still a problematic use of biotechnology: millions of people are addicted, and making it easier for them to get access would worsen the problem. Or would it?

Smoking, Ice-Cream and Logical Progressions: Why We Shouldn’t Ban Smoking in Outdoor Public Places

It’s a beautiful warm sunny day, and you have decided to take your children to join a group of friends for a barbecue at the local public park. The wine is flowing (orange juice for the kids), you have managed not to burn the sausages (vegetarian or otherwise), and there is even an ice-cream van parked a conveniently short walk away.

An idyllic scenario for many of us, I’m sure you will agree; one might even go so far as to suggest that this is exactly the sort of thing that public parks are there for; they represent a carefree environment in which we can enjoy the sunshine and engage in recreational communal activities with others.

Blessed are the wastrels, for their surplus could save the Earth

Reposted from an article in “the Conversation”. 

In a world where too many go to bed hungry, it comes as a shock to realise that more than half the world’s food production is left to rot, lost in transit, thrown out, or otherwise wasted. This loss is a humanitarian disaster. It’s a moral tragedy. It’s a blight on the conscience of the world.

It might ultimately be the salvation of the human species.

To understand why, consider that we live in a system that rewards efficiency. Just-in-time production, reduced inventories, providing the required service at just the right time with minimised wasted effort: those are the routes to profit (and hence survival) for today’s corporations. This type of lean manufacturing aims to squeeze costs as much as possible, pruning anything extraneous from the process. That’s the ideal, anyway; and many companies are furiously chasing after this ideal. Continue reading

Supermarkets, Spending, and Influences on Choice

Something of a twitter storm erupted last week over a poster placed in a supermarket window. The poster, placed in a branch of Sainsbury’s, issued a “50p Challenge”, urging employees to encourage every customer to “spend an additional 50p during each shopping trip between now and the years-end”. After a passer-by named Chris Dodd took a photo of the poster and posted it on twitter, a Sainsbury’s representative confirmed that the poster was intended only for employees and that it was not intended for public display. See a news report here. Continue reading

On the Supposed Importance of Cultural Traditions for Whaling Practice

Today is the first day of the 65th meeting of the International Whaling Commission (IWC). The commission, set up in 1946 to ensure the proper conservation of whale stocks and assist in the orderly development of the whaling industry, determines how many, which, and for what purpose, whales can be killed. The meeting beginning today is important because it will re-open discussion about Japan’s right to whale for the purposes of conducting scientific research. This past March, Japan lost this right because its findings were deemed to be of little use, and it was clear that the “scientific” nature of the killings were only a ruse. The IWC imposed a moratorium on commercial whaling in 1982, but still allows that the meat of whales killed for scientific purposes could be sold for profit. The Japanese whaling industry exploited this fact in order to sustain what was effectively a commercial whaling industry. Whales were killed in the name of scientific research, and then the meat was sold commercially. The International Court of Justice (ICJ) ruled that this violated the requirement imposed by the IWC that the killing of whales be only “for the purposes of scientific research.”

Of the many arguments deployed by the Japanese authorities concerning their right to whale, one is of particular interest to me; namely, that whaling constitutes an important aspect of Japanese culture, and thus ought to be permitted to continue.[1] In what follows, I claim that arguments based on cultural tradition alone are insufficient to generate a right to whale. In cases where the species of whale being killed is not endangered, then (on the condition that the method of whaling used is sustainable) no further reasons need be given in order to defend the practice. Whaling will be just like eating meat,[2] and arguments from cultural tradition will be superfluous. However, if the species of whale is endangered, then whaling is permissible only in cases of practical necessity. Continue reading

When warning is not informing: Alcohol labels will not be as straightforward as cigarette labels

News outlets have been discussing a call to require health warnings on alcoholic drinks comparable to those placed on cigarette packets. Amongst other recommendations, the All Party Parliamentary Group (APPG) on Alcohol Misuse has called on political parties to include a health warning on all alcohol labels, and to deliver a government-funded national public awareness campaign on alcohol-related health issues.

If this proposal is to be implemented, it is important to note that there is an important disanalogy with placing health warnings on cigarette packaging. Whilst cigarettes always damage health to some degree, a large body of evidence suggests that moderate drinking is not only non-harmful to health but may in fact promote it. Continue reading

Should Vegetarians Consider Eating Insects?

In the last few years, there has been a push from various bodies—including the UN—to get Western countries to adopt eating insects as an alternative to meat. Insects have been hailed as a type of super food. They are: rich in protein; environmentally friendly to harvest; sustainable; and, they’re already eaten, and enjoyed, in many other parts of the world. There have been a number of occasions recently that I’ve been asked, as a (moral) vegetarian, for my thoughts on eating insects. “What if…?” and “Would you…?” questions are quite a common occurrence for veggies, but this one actually got me thinking.

Should the NHS fund Weight Watchers schemes?

The National Institute for Health and Care Excellence (NICE) recently recommended that the NHS should learn from commercial weight loss programmes such as Weight Watchers, Rosemary Conley and Slimming World. The NICE guidelines suggested that doctors should take a “respectful” and “non-judgemental” tone when helping patients to lose weight. As well as this, GPs were encouraged to continue to identify overweight patients for referral to state-funded commercial weight loss schemes, run by companies such as Weight Watchers, with obese adults being given priority.

The plan is estimated to cost hundreds of millions of pounds, but is also likely to save the NHS vast amounts in the long run, if successful in reducing obesity. Approximately 1 in 4 adults in the UK are obese, a condition that is linked with other ailments such as diabetes, heart disease and some cancers. The costs to the NHS attributable to people being overweight and obese are projected to reach £9.7 billion by 2050. Figures show that Weight Watchers and similar schemes manage to reduce participant’s body weight by 3 per cent, and NICE believe that even this small amount will help in the long term. Is it right, therefore, that the NHS subsidise the cost of these commercially run weight loss schemes?
