Your bones may need calcium, but here's why it's time to moove on from milk

Because of a growing body of research, there is a dawning appreciation that allergy to the proteins in cow’s milk is behind a range of childhood illnesses.

Thanks in no small part to the efforts of the Milk Marketing Board from the 1950s onwards (do you remember “Full of natural goodness”, “Milk’s gotta lotta bottle”, or “Drinka pinta milka day”?) dairy produce enjoys an almost unassailable position in British dietary culture. Milk is seen as vital, an indispensable source of calcium and vitamin D, the foundation stone for healthy teeth and bones.

The health-care professions have been as taken in as anyone; not even evidence implicating dairy in the development of later-life problems such as heart disease has been able to undermine the belief that, for our children to get the best start, they need to be pumped full of cheese and yogurt, all washed down with a glass of nice-coldice- cold milk.

This cultural enthusiasm for dairy led the medical profession into a collective, decades-long blindness. Even today, parents who believe their child to be allergic to milk are likely to be dismissed as oddballs, clutching at improbable straws in an attempt to understand their offspring’s health problems. Dreadful eczema? That’s a skin disease. Intractable abdominal pain and digestive mayhem? There must be something wrong with the gut. Chronic cough and mucous? That’ll be the lungs.

Milk, after all, is what babies are made of. What could be wrong with such a natural, wholesome food? However, because of a growing body of research, there is a dawning appreciation that allergy to the proteins in cow’s milk is behind a range of childhood illnesses.

The journey towards this understanding has been made difficult by several confounding factors. First, there is more than one type of allergic reaction. Immediate hypersensitivity to milk, which is rarer, is easy to diagnose. Directly after exposure to cow’s milk protein, the affected individual displays a florid response, which includes swelling of the lips, face and eyes; a wheeze and breathing difficulty; and a rash called urticaria, which looks like widespread nettle stings.

Much more common in cow’s milk protein allergy (CMPA) is delayed hypersensitivity. This is tricky. There is no clear link in time between exposure and symptoms. These babies tend to have difficult-to-treat eczema, refractory respiratory problems and a range of digestive disorders such as reflux (where acid stomach contents come back into the gullet and mouth), diarrhoea or constipation, colicky pain and even bleeding into the bowel.

We still do not completely understand delayed hypersensitivity and it is likely to be more common than its currently estimated prevalence of around 5 per cent.

Even when delayed hypersensitivity is suspected, there are a number of factors that can frustrate the diagnosis. Unlike immediate hypersensitivity, there is no blood or skin-prick test that can be given. Confirmation can only come from strict exclusion diets, where one would expect symptoms to resolve over a period of between two and eight weeks.

Exclusion diets are hard to stick to. Doctors frequently advise parents to switch to soya-based products, but there is crossreactivity between cow’s milk and soya protein in around 60 per cent of cases. Failure to improve when on a soya-only diet is often mistakenly interpreted as ruling out CMPA.

Another common misconception is that breastfed babies can’t develop CMPA, yet the offending proteins in a dairy-consuming mother will cross into breast milk and provoke allergy in just the same way as with bottle-fed infants.

From an evolutionary perspective, consuming milk beyond babyhood is unnatural, yet all infants depend on milk in their first year or so. Breastfeeding mothers with allergic offspring can go dairyfree but bottle-fed babies are, figuratively speaking, up a gum tree.

Fortunately, there are now a number of formulas available to treat CMPA. In each, the protein components are hydrolysed – chemically “chopped up” into smaller units –which are less likely to provoke an allergic response. But these are very expensive and their growing use is a source of concern to those responsible for NHS prescribing budgets.

A better long-term solution is to encourage and support breastfeeding – currently fewer than a quarter of new mothers are still exclusively breastfeeding at six weeks.

This needs to be coupled with a thorough rethink of our relationship with dairy foods. Even experts in the field of CMPA remain spellbound by the belief that milk is essential for calcium and vitamin D, advising breastfeeding mothers to take artificial supplements if they are cutting out dairy.

But, in reality, milk is a relatively mediocre source of these nutrients. There are innumerable other foodstuffs that carry more calcium than milk – broccoli, figs, almonds, sesame seeds and leafy green vegetables, to name but a few.

As for vitamin D, getting ourselves and our children out into natural sunlight every day is nature’s time-honoured solution. Who knows, we might even inculcate a renewed enthusiasm for fresh air and exercise into the bargain.

No, the Brexit vote wasn't just about immigration

The data shows that most voters want a fairer society. Labour must fight for this in the Brexit negotiations. 

The result of the UK referendum to leave the European Union has shaken the political establishment to its core. As I have argued since then, it should be a wakeup call to all political parties.

Some have also argued that the referendum result is having international repercussions, with the election of Donald Trump to the White House cited as "Brexit Plus Plus". With the imminent election in France, and Germany’s later this year, responsible analysts are trying to understand why people voted the way they did and what this means. Too often, there are knee jerk explanations without any evidentiary justification to back them up. 

Analysis of who voted to leave shows the majority of people who voted to leave live in the South of England, and 59 per cent were from the middle classes (A, B, C1). Only 21 per cent of people in the lowest income groups voted to leave.

Analysis of why people voted as they did is more complex. This includes an increase in Euroscepticism particularly from older, middle class voters; concerns about globalisation and the impact on jobs; inequalities and being left behind; and new voters who didn’t vote in the 2015 General Election, for whom immigration was a concern. When this analysis is overlaid on analysis of that election, some themes emerge. The attitudes and values of the majority of the British public are firmly rooted in the desire for a fairer society, based on principles of equality and social justice. Although immigration played a part in the election and referendum results, perceived competence, being "left behind" and disillusionment with the direction of change were the key drivers.

Whether people voted to remain or leave, they did so because they believed that they and their families would be better off, and the majority who voted believed they would be better off if we leave the EU. Labour accepts and respects this. We have said that we will vote for Article 50, but we intend to hold this Tory government to account to ensure we get the best possible deal for the country.

In his speech last week, Jeremy Corbyn set out the issues that Labour will hold the government to account on. We have been absolutely clear that we want tariff-free access to the single market, to ensure that Britain continues to trade openly with our European neighbours, and to protect the cost of living for families struggling to get by. Getting the best deal for the UK means that we must continue to have a strong relationship with our EU neighbours.

Under my work and pensions portfolio, for example, we know that 40 per cent of pension funds are invested outside of the UK. If we want to guarantee a dignified and secure retirement for our pensioners, we must ensure that savers can get the best returns for the investments they make.

We also know that many of the protections that have until now been offered by the European Union must continue to be guaranteed when we leave. Provisions that secure the rights of disabled people, or that protect worker’s rights are an essential part of British society, enhanced by the EU. These cannot be torn up by the Tories.

Defending these rights is also at the heart of our approach to immigration. The dire anti-migrant rhetoric from some parts of the media and certain politicians, is reprehensible. I reject this scapegoating, which has fear and blame at its heart, because it is not true. Blaming migrants for nearly seven wasted years of Tory austerity when they are net contributors of over £2bn a year to the economy is perverse.

Of course we need to respond when public services are coming under pressure from local population increases. That’s why Labour wants to reinstate the Migration Impact Fund that the Tories abolished. We also need to ensure new members of communities get to know their new neighbours and what’s expected of them.

We believe that migrants’ broader contribution to British society has too often been obscured by the actions of unscrupulous employers, who have exploited new arrivals at the expense of local labour. A vast network of recruitment and employment agencies has developed in this country. It is worth hundreds of billions of pounds. Last year over 1.3m people were employed in the UK by these agencies. In 2007, 1 in 7 of these people came from the EU. We should ask how many are recruited directly from the EU now, and offered precarious work on very low wages whilst undercutting local labour. Labour will put an end to this practice, in order to protect both those who come here to work and those that grew up here.

Importantly, however, we cannot let our exit from the EU leave us with skill shortages in our economy. Our current workforce planning is woeful, particularly for the long-term. We need to reduce our need for migrant labour by ensuring our young, and our not so young, are trained for the jobs of the future, from carers to coders. Again, the Conservatives have undermined people’s chances of getting on by cutting college funding and the adult skills budget.

Unlike the government, Labour will not shirk from our responsibilities to the nation. Our plans for Brexit will respect the referendum result, whilst holding the Government to account and delivering a better future for all our people, not just the privileged few.
