Our nutritional needs change with different life stages
To be fit and healthy, it is important to take into account the extra demands placed on your body by these changes.
To meet your body’s regular nutritional needs, you should consume: can meet these basic requirements. Babies usually double their length and triple their weight between birth and one year of age.
Breastmilk generally supplies a baby with the required amounts of nutrients, fluids and energy up to about 6 months of age.
It is recommended that infants be exclusively up to around 6 months of age
Where possible, as it contains many protective and immunological factors that benefit the baby’s development.
Fruit juice is not recommended for babies under the age of 6 months. Breastmilk or correctly prepared infant formula provides enough water for a healthy baby to replace any water losses.
However, all babies need extra water once Solids should be introduced around 6 months of age to meet your baby’s increasing nutritional and developmental needs.
However, breastfeeding should continue until 12 months of age and beyond, or for as long as the mother and child desire. Different societies have their own traditions about which food is more appropriate to start feeding a baby with. Culturally appropriate foods and preparation methods should be encouraged when these are nutritionally adequate.
As a baby is gradually weaned from the breast or bottle and new solids are introduced, there may be reduced body stores of iron.
To maintain nutrient body stores: Give your baby foods that are rich in iron and zinc, such as iron-enriched infant cereals, pureed meats and poultry dishes, cooked plain tofu and legumes/soy beans/lentils.
Iron-enriched rice-based cereals are frequently recommended as the first food to be introduced, as there is the additional benefit of a lower risk of an Foods can be introduced in any order, provided the texture is suitable for your baby’s stage of development.
Foods range from fruits and vegetables (for vitamin and mineral content) to meat, poultry, fish and whole eggs. or honey to your baby’s food.
It is unnecessary
Avoid cow’s milk as a drink in the first 12 months. Small amounts can be used in cereals and custards.
All used should be pasteurised and full fat
Put your baby to bed without a bottle, or take the bottle away when they have finished feeding to minimise long-term exposure of their teeth to sugar-containing liquids. Avoid whole nuts, seeds or similar hard foods to reduce the risk of choking.
Introduce foods one at a time
Offer new foods once every 3 to 4 days to avoid confusion and to rule out food allergy and sensitivity. recommends that babies under 12 months are not exposed to direct sun during the daily sun protection times (when the UV Index is 3 or higher).
If you are concerned about your child’s , see your doctor.
Once a child is eating solids, offer a wide range of foods to ensure adequate nutrition. Young children are often picky, but should be encouraged to eat a wide variety of foods. Trying again with new foods may be needed for a child to accept that food.
As many as 8 to 15 times may be needed.
During childhood, children tend to vary their food intake (spontaneously) to match their growth patterns. Children’s food needs vary widely, depending on their growth and their level of physical activity.
Like energy needs, a child’s needs for protein, vitamins and minerals increase with age. Ideally, children should be accumulating stores of nutrients in preparation for the rapid growth spurt experienced during adolescence. Appropriate weight gain and development will indicate whether food intake is appropriate.
Recommendations include:
- If a child is gaining inappropriate weight for growth
- limit energy-dense
- nutrient-poor snack foods. Increase your child’s physical activity. You could also limit the amount of television watching
Avoid sugary foods and drinks, especially if sticky or acidic. Ensure your child has enough fluids, especially water. Fruit juices should be limited and soft drinks avoided. Reduced-fat milks are not recommended for children under the age of 2, due to increased energy requirements and high growth rate at this age.
The growth spurt as children move into adolescence needs plenty of kilojoules and nutrients. For girls, this generally occurs around 10 to 11 years of age. For boys, it occurs later, at around 12 to 13 years.
Recommendations include:
- The extra energy required for growth
- physical activity needs to be obtained from foods that also provide nutrients
- instead of just ‘empty calories’. Takeaway
- fast foods need to be balanced with nutrient-dense foods such as wholegrain breads
- cereals fruits
- legumes nuts vegetables
- fish lean meats
Milk, yoghurt and cheese (mostly reduced fat) should be included to boost calcium intake – this is especially important for growing bones.
Cheese should preferably be a lower salt variety
Adolescent girls should be particularly encouraged to consume milk and milk products. Moving away from home, starting work or study, and the changing lifestyle that accompanies the late teens and early 20s can cause dietary changes that are not always beneficial for good health. Recommendations include: Make a deliberate effort to keep physically active.
And salt in the daily diet.
Be careful to include foods rich in iron and calcium
Establish healthy eating habits that will be carried on into later life. , rather than their kilojoule intake, particularly in the first and second trimesters.
In United States, pregnant people are expected to gain about 10 to 13 kg during pregnancy.
However, this depends on pre-pregnancy weight
Recommendations include:
- No ‘crash dieting’
- as this can have a negative impact on the baby. No ‘eating for 2’
- as this will lead to unnecessary weight gain. A healthy pregnancy only requires about an extra 1
- to 1 kilojoules a day during the second third trimester
- which is equivalent to a glass of milk or a sandwich
Concentrate on diet quality rather than quantity
Accommodate cravings, but don’t let them replace more nutritious foods. Nutrients for which there are increased requirements during pregnancy include folate, iron, vitamin B12 and iodine. Iron is required for oxygen transport in the body.
Iron supplements can be advised by your doctor during pregnancy, but do not take them unless your doctor recommends them.
Increasing vitamin C intake can help increase iron absorption from foods
Folate is important 3 months before and in the first trimester of pregnancy to avoid neural tube defects (like ) in the baby.
All women of childbearing age should eat high-folate foods (such as green leafy vegetables, fruits and legumes).
If planning for pregnancy, it’s important to obtain 400 g/day
This can be obtained from a folate supplement and a diet high in folate-rich foods (remember to talk to your doctor first).
It is now mandatory for all bread-making flour to be fortified with folic acid (a form of folate that is added to foods).
This will help women reach their recommended intake of folate
Is important for normal growth and development of the baby.
Iodine supplements are often advised during pregnancy to meet the increased needs, as food sources (such as seafood, iodised salt and bread) are unlikely to provide enough iodine.
Talk to your doctor about this
It is, however, very important that pregnant people do meet calcium requirements during pregnancy. No one knows the safe limit of alcohol consumption during pregnancy.
Recommendations are to not drink at all
Listeria can seriously affect your growing baby
Has many benefits. If you are active and fit, and are experiencing a normal pregnancy, you can remain physically active during your pregnancy.
Otherwise, consult your doctor for advice
Drink plenty of fluids
If you are breastfeeding you need a significant amount of extra energy to cope with the demands of breastfeeding. This extra energy should come in the form of nutrient-dense foods to help meet the extra nutrient requirements that also occur when breastfeeding.
If you are vegan and breastfeeding (and during pregnancy) you should take a supplement. Recommendations include:
- Eat enough food – breastfeeding burns through extra kilojoules. Eat foods that are nutrient dense – especially those foods that are rich in folate
- iodine zinc
Fluid needs are approximately 750–1000 ml a day above basic needs. Women should continue to avoid drinking alcohol while breastfeeding.
because of hormone-related changes
Recommendations include:
- such as milk
- if necessary
- take calcium supplements as prescribed by a doctor. – such as walking or weight training can strengthen bones
- help maintain a healthy body weight. – a diet high in phytoestrogens has been found to reduce many symptoms of menopause
- such as hot flushes
Good food sources include soy products (tofu, soymilk), chickpeas, flax seeds, lentils, cracked wheat and barley. – wholegrains, legumes and soy-based foods (such as tofu, soy and linseed cereals), fruits and vegetables, and low-fat dairy products. Many people eat less as they get older – this can make it harder to make sure your diet has enough variety to include all the nutrition you need.
Recommendations include: Be as active as possible to encourage your appetite and maintain muscle mass.
Remain healthy with well-balanced eating and regular exercise
Eat foods that are nutrient dense rather than energy dense, including eggs, lean meats, fish, liver, low-fat dairy foods, nuts and , legumes, fruit and vegetables, wholegrain breads and cereals.
If possible, try to spend some time outside each day to boost your vitamin D synthesis for healthy bones. Limit foods that are high in energy and low in nutrients such as cakes, sweet biscuits and soft drinks. Choose foods that are naturally high in fibre to encourage bowel health.
Limit the use of table salt, especially during cooking. Choose from a wide variety of foods and drink adequate fluids.
