An Australian study has concluded that globally accepted guidelines to drink 8 glasses of water a day are unnecessary.
The Monash Biomedicine Discovery Institute associate professor behind it said people have “died, in certain circumstances, because they slavishly followed these recommendations.”
The research discovered a new “swallowing reflex” that protects us, becoming “inhibited once enough water has been drunk”.
We are advised to “just drink according to thirst rather than an elaborate schedule.”
I fear this is actually very bad advice from the wrong conclusion.
Of course, we have some resistance to all over-consumption. And, of course, extreme over-consumption of anything can be dangerous.
But my understanding is that the full weight of scientific evidence points to us anticipating hunger early, while becoming thirsty late.
So we need these guidelines to encourage us to hydrate. And even low levels of dehydration affect us quite seriously.
The Australian researchers acknowledge this for elderly people.
Academic research is often blown out of proportion by the media. But academics have a responsibility too.
This report was based on just 20 participants and apparently didn’t correlate with other factors.
But they make some interesting points. My thanks to Aqua Maestro in the United States and my eldest daughter in Britain.
• Americans now recycle over 1 million single-serve PET water bottles every hour.
• More than 150 US colleges use graduation gowns and caps made from recycled PET.
• The average weight of a 50cl PET water bottle in the United States has halved since 2000 to under 10 grams.
• A pop up bar in London last month handed out free mineral water, while displaying 10 regional varieties of sea water with messages to highlight the dangers of swimming in the sea. An average 22 people are rescued by the Royal National Lifeboat Institution every day.
• 4 members of the Zenith team successfully completed the Royal National Lifeboat Institution’s H2Only challenge, raising hundreds of pounds in the process. For 10 days, the only drink they were allowed to consume was water.
To mark World Water Week recently, both Coca-Cola and PepsiCo showed how seriously they have acted on water stewardship and waste.
PepsiCo declared it had provided 9 million people with access to safe water since 2005. Coca-Cola has reached a further 2 million in Africa.
PepsiCo reduced its absolute water usage in 2015, despite manufacturing volume growth.
Coca-Cola announced it had become the first Fortune 500 company to replenish more water than it uses. In 2015, it used 300 billion litres and returned 338 billion litres. The Coke system now uses 27% less water per litre of product than in 2004, just 1.98 litres per litre of product.
September notched up 52 food and drink industry transactions on the bevblog.net mergers and acquisitions database.
3 involved sums greater than $1,000 million, 2 of them many times more:
• $66,000 million for Germany’s Bayer to buy US-based Monsanto with interests in agribusiness and ingredients.
• $9,900 million sales from the merger of Coca-Cola West and Coca-Cola East Japan to form Coca-Cola Bottlers Japan from April 2017.
• $1,090 million for Coca-Cola Femsa in Mexico to purchase fellow Coca-Cola bottler Vonpar in Brazil.
Among the 52 total, 11 were in alcohol, 8 in ingredients, 6 in packaging, 6 in soft drinks, 3 in confectionery and 3 in dairy.
21 were within national borders and 31 international. 26 featured the United States, 11 the United Kingdom, 6 France, 5 Switzerland, 4 Germany, 3 Australia, 3 Mexico and 3 the Netherlands.
Carton recycling in the European Union is at last within sight of reaching 50%. From under 30% in 2005, it has risen to 44% in 2015.
That represents a gigantic 16,000 million cartons. Apparently, the combined figure for recycling and energy recovery is an even higher 74%.
The recycling tonnage, however, has fallen slightly. But even that may be a good sign, if lightweighting requires less material.
Tetra Pak’s latest Index report on 100% juice presents an upbeat tone, based on extensive research including a survey of consumers in their thousands across 7 of the world’s top 10 markets. This found that:
• Over 80% of consumers see pure fruit juice as tasty, natural, healthy and refreshing.
• 42% drink it at least once a day.
• 47% is consumed at breakfast.
• More than 90% is consumed at home.
• 63% of respondents were aware of the sugar debate, but only 12% of these reported any doubts.
• For lapsed users, the leading replacement is water on 57% and tea on 36%.
Among other findings, I noted:
• Orange accounts for 46% of global consumption and apple 17%. Coconut has risen to … 1%.
• Premium not from concentrate juices have grown to take 29% of volume.
• Most of the leading national markets are forecast to remain static or declining, with the exception of significant growth from Brazil and China.
40 food and drink transactions were recorded in the bevblog.net mergers and acquisitions database for August.
6 were valued at between $250 million and $500 million, with just 1 above that level:
• $765 million for the US packaging takeover of AEP Industries by Berry Plastics.
Of the 40 total, 9 were in alcohol, 5 in soft drinks, 4 in bakery, 4 in snacks, 3 in dairy and 3 in packaging.
21 were within national borders and 19 international, involving 22 countries. The United States featured in 18, the United Kingdom in 11, followed by Canada on 3 and France on 3.
Could South Africa be leading the way ?
I’m not aware of any country that has a comprehensive nutrition strategy, which then forms the basis for planning production on farms.
Yes, many have national dietary guidelines. But without any connection to agricultural policy.
At least South Africa has quantified the challenges and set some goals.
The challenges are huge and come from opposing directions:
• 63% of women and 41% of men are overweight or obese.
• 14% of children under 5 are overweight.
• Yet 29% of children are affected by stunting.
The goals for 2025 aim to:
• reduce stunting to 10%
• reduce underweight to 5%.
