Milk and Nutrition in the news

The Times March 31st 2017

Almost half of young people claim they are intolerant or allergic to milk.

The Food Standards Agency Food and You Survey found

46% 16-24 year olds said they had adverse reaction to milk.

Less than 1 in 10 older people had a problem with dairy.

In Britain only 5% are thought to suffer maldigestion of lactose – the sugar in milk according to BNF.

Bloggers are promoting cleam eating where gluten and milk are back for health.

Ella Woodward recommends raw coconut water or almond milk as milk alternative.

13% said had adverse reaction to gluten.

Less than 25%of people with food intolerance had had a clinical diagnosis of their condition and those who said they had food allergy less than 50% had seen doctor about it.

The number of people claiming adverse reaction to foods is rising.

In 2014 10% lived in household where someone had food allergy.

In 2015 that was 13%.

Britons drank 6.1 million fewer pints of milk last year – £240 million sales – Nielsen.

NHS warns that cutting out dairy products can result in calcium deficiency.

67% of women took most or all of the responsibility for cooking and only 30% of men.

 

 

News on DRVs – things are changing

Dietary Reference Values (DRVs) describe the distribution of requirements for energy and nutrients in a population.

SACN has recommended

Daily calorie requirements for men go up from 2550 to 2650 and for women from 1940 to 2079.

These recommendations are for healthy people with BMI of 22.5 – average in UK is BMI of 27.

The larger you are the more calories you require as there is more tissue and bulk.

Teenagers according to evidence need more calories as they have higher level of activity.

Pregnancy remains at just under 200 calories extra a day for the last 3 months of pregnancy and breastfeeding burns 335 calories a day.

Most of our daily calorie intake is needed to keep us ticking over and maintain body temperature.

They are not recommendations or goals for individuals.

In order to take account of the range of nutritional requirements in a population, there are 3 DRVs:

1. Estimated Average Requirement (EAR) – the average requirement of energy or a nutrient in a group of people, for example, 50 per cent will require less and 50 per cent will require more.
2. Reference Nutrient Intake (RNI) – the amount of a nutrient that is likely to meet the needs of most (97.5 per cent) of the population.
3. Lower Reference Nutrient Intake (LRNI) – the amount of a nutrient that is likely to meet the needs of only a small number (2.5 per cent) of people in the population with low requirements.

RNIs, which are set at the upper end of nutrient requirements, were not set for energy because, unlike other nutrients, an intake of energy in excess of requirements can have adverse effects in terms of weight gain.  Requirements for energy intake will also depend on energy expenditure.  A chronic excess of dietary energy intake over energy expenditure is related to overweight and obesity.  Recommendations for energy were therefore set as EARs for different population groups and were based on estimates of energy expenditure.

The UK DRVs for energy have recently been reviewed by the Scientific Advisory Committee on Nutrition (SACN).
SACN’s report updates the EAR values from the Department of Health’s 1991 report, which may be of relevance for our nutritional analysis programme.
