BEVERAGES - A key to a healthy life EDITORIAL Dear Reader,

Why we need liquid

Water, or more accurately, liquid is a vital link to our life. We cannot live without it for more than 100 hours, whereas with other nutrients we can go without them for many days or weeks.

1. As a basic substance of every cell and an excellent solvent for many substances, e.g. nutrient.

Water has many important functions.

These include:

Normally, we need around 1.5 to 2 litres of liquid a day to keep our bodies properly hydrated. The form of liquid intake can vary. It could be plain water but it could also be coffee (in moderate quantities), tea or milk-based beverages. Most of these drinks not only provide liquid but also several important nutrients and plant components, such as minerals, polyphenols and vitamins.

2. As a lubricant:

This issue of NutriPro gives you an overview of the different kinds of beverages which are important for daily liquid intake. We hope you find this of interest.

3. Transportation of many substances, including nutrients (e.g. glucose), hormones and oxygen, to cells:

• Protection for body organs (e.g. the brain, eyes and lungs) against shock.

• A moisturizer that allows, for example, eyes to wash away dirt and saliva to make it easier to chew and swallow food.

• A means of returning waste products such as carbon dioxide, lactic acid and ammonia to the lungs, kidney and digestive system for excretion.

Michael Kernkamp Head of Global Branded Beverages NESTLÉ PROFESSIONAL

4. Many chemical reactions: • Direct participation in enzymatic degradation, e.g. the digestion of starch in glucose, and in the synthesis of proteins from amino acids.

Dear All, Water plays many roles in our body it is a transportation system, a lubricant, a medium for metabolic reactions and a thermoregulator.

5. Reducing body temperature by the evaporation of sweat from the skin when the body overheats.

Getting enough liquid doesn´t really sound like a problem, but it can be, especially for babies and the elderly, because the “thirsty” sensation gets weaker as we age. Dehydration, a depletion of body water, will cause symptoms more rapidly than a deficiency in any other nutrient. All beverages or liquids are a source of water.

The %-change of body water

Even solid foods contain water. Finding the right beverage and food for every situation is key in maintaining a healthy life.

What would we be without water?

Water: Two parts hydrogen, one part oxygen – H2O. A simple substance, but without it human life cannot survive. The sea within us depends on: 1. Age • Babies and young children have more water than adults.

2. Gender • Women have less water than men. Women have a naturally higher percentage of body fat.

BRAIN 73%

3. Weight • The obese have less water (expressed as a percentage) than thin people.

In the human body water is found in varying proportions in all organs and tissues.

Water in the body Water in the body is located:

LUNGS 83%

HEART 73%

BLOOD 79% MUSCLES 79%

• Outside cells (extracellular) This water (around one third of total body water) is primarily that found in the blood and fluid between cells (called interstitial fluid).

Furthermore, it includes, for example, fluid in the lymphs, eyes, joints and spinal cord.

Balance is important An adequate fluid intake is essential for health and performance. This means that, every day, fluid intake must equal water loss.

However, how much liquid do we need every day? This depends on:

energy expenditure, the greater the need for water.

Age: Infants and young children need more liquid in proportion to their body weight than adults; they cannot concentrate their urine as efficiently as adults and they lose proportionately more water through evaporation.

Climate: Temperature and humidity are important factors.

Gender: Men need more fluid than women.

Physical activity: The greater the

State of health: Several clinical conditions require a greater liquid intake, especially infections (fever) and diarrhoea.

Liquid intake comes from a variety of sources: Different kinds of foods as well as beverages or liquids are sources of water. In fact, it is estimated that around 30% of our daily liquid intake is met through food. Very good sources are fruit and vegetables - most of which contain around 80% water. Protein-rich food such as meat, chicken or dairy products normally contain less than 75% water, whereas grain products such as bread, baked products or pasta have no more than 50% water.

Who needs to drink more?

Athletes Adequate liquid intake for athletes is essential for an optimal performance. A loss of as little as 4-6% of body water can impair muscular strength and endurance.

The type as well as the intensity and the duration of the activity will determine the need for liquids.

Expectant & breast-feeding mothers Women who are pregnant or breast feeding need additional liquids to remain hydrated:

val ues for an n a temperate limate.

• For expectant mothers: Drink around 1.5 l a day.

• For breast-feeding mothers: Drink around 1.7 l a day.

The sick Some illnesses, such as fever, vomiting and diarrhoea, cause additional fluid loss. This loss must be replaced with water or other solutions with electrolytes.

The sensation of thirst declines with age Thirst is a biological indication of dehydration. As people grow older, however, this warning signal gets weaker, which can reduce liquid intake.

Dehydration can cause problems such as constipation, muscle weakness and, in the elderly, a sensation of fatigue and lethargy.

It is very important, therefore, that people over the age of 65 drink very frequently, even when they do not feel thirsty.

GOOD TO KNOW

Tips for more liquid intake...

Coffee: Part of the daily liquid intake Some facts about coffee • Coffee is the second most traded product in the world, after oil.

• Worldwide, more than 1400 million cups of coffee are drunk every day.

• Around 17% of green coffee beans are used to make soluble coffee.

• The most common varieties of coffee are coffea arabica & coffea canephora (robusta).

• Scientific analyses have identified more than 1000 different aromatic com pounds in coffee.

Coffee: Good and fun

A cup of coffee in the morning is one of the most popular ways of starting the day. It is primarily enjoyed for its taste and aroma, but also for its positive functional effects.

Part of the daily liquid intake • A moderate coffee consumption (3 – 5 cups a day) will have no adverse effect on hydration and can also contribute to the daily liquid intake.

Expectant mothers • Should limit their daily coffee consumption.

Recent guidelines recommend that a caffeine intake of 200 mg per day (approximately two regular cups of coffee) is safe.

Health benefits • Coffee – especially caffeine – improves mental reaction and concentration, increases alertness and athletic performance.

People with a high cholesterol level • It is possible that drinking excessive quantities of unfiltered coffee (around 10 cups per day) may cause elevated levels of blood cholesterol.

• Coffee may help reduce the risk of several diseases, such as Parkinson’s disease, type-2 diabetes and liver cancer.

A possible reason is that coffee is a very good source of polyphenols.

People with an insufficient calcium intake • People with a deficient calcium intake should limit their coffee consumption (no more than 3 - 5 cups a day), because excessive caffeine intake may increase calcium excretion.

• A current epidemiologic study indicates that most people can drink coffee without increasing their risk of any clinically significant change in their heart rhythm.

Additives such as sugar and cream • Many coffee drinkers add sugar or cream to their coffee. Each teaspoon of sugar adds around 15 kcal and each 15 ml quantity of whipping cream adds more than 50 kcal.

A solution could be to use only low-fat milk and to reduce added sugar.

Tea: A global beverage Some facts about tea • Currently there are more than 3000 types of tea, and up to 300 different plants, or parts of their structure, are used in making blended, scented, flavoured or fruit teas.

• Tea is a very good source of flavonoids.

• Tea is increasingly associated with relaxation (wellness), health benefits and refreshment.

• Tea is increasingly consumed as a ready-to-drink beverage, e.g. NESTEA green tea with honey.

Different kinds of tea Besides the basic types of tea (Black, Oolong, PuErh, Green & White), there are many varieties on the market. These can be classified according to: 1. Region of production For example: • Darjeeling: located in the north-eastern part of India, it has a fine flowery aroma, a light body and a taste reminiscent of Muscatel. Sometimes it is called the “champagne of tea”.

• Assam: located in the northeastern part of India, has a malty flavour and a strong, bright colour. Normally it is used as a breakfast tea

2. Blends For example: For example: • English breakfast tea: A blend • Earl Grey: Black tea, infused with bergamot oil. Sometimes of several black teas, derived it is classified as a blended tea. from various regions, including India, Sri lanka, Kenya, Malawi and China.

3. Flavour There are two methods of flavouring tea: A flavoured fruit liquid, e.g. strawberry, cherry; herbs, e.g. • Jasmine Tea: A green tea is scented with jasmine flowers. cardamom; flowers, e.g. vanilla, roses; or other, is sprayed on the leaves, or granules are mixed in with the tea.

With or without milk?

Around 99% of tea drinkers in India and Great Britain add milk to their tea, whereas this habit is unusual in the rest of Europe, the United States and other countries where tea is consumed.

In the UK, a study has shown that black tea consumption with milk increases the overall calcium intake of middle-aged women by around 3%. While milk has a positive effect on bone growth and development, if drunk in excess, it may inhibit the effect of tea on iron absorption.

As shown by a recent NESTlé study, adding milk to coffee does not alter the overall bioavailability of polyphenols, which are powerful antioxidants. However, it is still not clear whether milk specifically inhibits the absorption of flavanoids, a sub-group of polyphenols that are the main antioxidants in tea.
