Life stages
As we go through life, we move through different stages of development, each with its own biological, psychological, and social characteristics. At each life stage, our motor skills, social relationships, and cognitive abilities change, along with our nutritional needs and key psychological concerns. Top ten nutrients offers an overview of the nutrients recommended at each life stage and the right foods helps describe where to find them.
Pregnancy
The concept of ‘eating for two’ is over simplified, but nutrition during pregnancy is especially important, for the health of both mother and baby. The only source of nutrition a developing baby gets is from it’s mother, so it is crucial for the mother to get the right nutrients they need both before and during pregnancy.
For the mother, good nutrition could reduce the risk of key nutrient deficiencies such as anaemia and ease symptoms of fatigue, as well as reduce the likelihood of gestational diabetes and manage morning sickness. For the baby, the food consumed by the mother during this time directly affects the development of the brain and spinal cord, as well as influencing a child’s metabolism and immune system. Increasingly more research is also linking certain diseases, such as diabetes, back to the womb - emphasising the importance of prenatal nutrition.
Having said this, it is well known that mothers can have battles with eating during pregnancy: avoiding certain foods, craving for others, acid reflux, morning sickness, nausea. Our advice would be to go with how you are feeling, but play particular attention to key nutrients required for baby brain development.
-
A healthy, balanced diet, as recommended for all adults, but with emphasis on long chain omega 3 fatty acids, vitamins A, B9 (folic acid), B12, C, and D, iron, iodine and antioxidants to help the baby’s brain develop.
Regularly eating food rich in antioxidants and anti-inflammatory nutrients to prevent maternal inflammation, which can lead to mental health issues and disruption of brain development in children.
Reducing or avoiding foods that are high in sugar and omega-6 and low in omega-3 EPA, to reduce chances of inflammation.
Eating oily fish at least twice a week..
Important note
Oily fish is a good source of many of the recommended nutrients during pregnancy. Many pregnant women worry that by eating fish regularly, the baby will be exposed to too much mercury. However, you would need to eat several kilograms of fish each week for mercury levels to be of concern.
-
DHA and EPA
—
Helps to develop the baby’s brain, including memory, learning, behaviour, neural repair, vision and emotions. Low levels of DHA are linked to dyslexia, ADHD, autism, and dementia.
Found in oily fish, like mackerel, sardines, anchovies, salmon and herring, and plant based sources such as algae and seaweed.
Vitamins C and K
—
Lowers the risk of miscarriage from oxidative stress, protects the baby’s brain tissue, and prevents birth defects.
Found in citrus fruits, potatoes, and dark green leafy vegetables.
Folic acid
—
Protects the baby against spinal cord defects and brain damage.
Found in green leafy vegetables, citrus fruits, bananas, and beans.
Choline
—
Heightens mother and baby’s memory and learning.
Found in eggs, poultry, cruciferous vegetables, nuts, legumes.
Iron
—
Many pregnant women suffer with iron deficiency, which could cause neural complications within a developing foetus.
Found in broccoli, shellfish, tofu, nuts, beans.
Other good nutrients
—
Vitamin D, vitamin B12 and zinc.
Infancy & childhood
The first years of childhood, especially the first two years, set the foundation for thinking, learning and overall brain health. Good nutrition is fundamental to this. What we eat, and the behaviours we learn towards food during childhood, help to determine both our brain and physical health as we get older. This includes our mental health, concentration, hyperactivity, and risk of developing dementia, as well as our potential for developing diabetes, heart disease and cancer. A lack of the right nutrients might result in poor ability to sleep, issues concentrating, hyperactivity, mood swings and destructive behaviour.
-
A healthy balanced diet, focused on nutrients and eating patterns that support motor and physical development as well as growth. Sources rich in DHA, EPA, vitamins A, B12, and D, folic acid, iron, iodine, zinc and choline help to optimise brain development.
Eating regularly gives developing brains a more consistent supply of energy and helps with concentration.
Reducing or cutting out junk food and additives can help to minimise symptons of dyslexia, ADHD and autistic spectrum disorder.
-
DHA and EPA
—
Helps to improve memory, cognition, information processing, learning, and development of skills such as reading, writing and spelling.
Low levels of DHA are linked to dyslexia, ADHD, and autism.
Found in oily fish, like mackerel, sardines, anchovies, salmon and herring, and plant based sources such as algae and seaweed.
Iron
—
Improves cognition, memory and mood.
Found in shellfish, red meat, liver, beans, broccoli, green leafy vegetables, fortified cereals.
Zinc
—
Develops and grows the brain and other organs, and improves immune system function.
Found in shellfish, legumes, meat, nuts.
Calcium
—
Regulates electrical signalling in the brain.
Found in dairy, green leafy vegetables, and tofu.
Other good nutrients
—
Vitamins A, folic acid, vitamins B12 and D, iron, iodine, zinc and choline.
Adolescence
During adolescence, we become less naturally impulsive and emotional and more reasoning-based, due to the development of the prefrontal cortex. Considering the significant changes that happen in the brain at this time, adolescents are particularly vulnerable to anxiety, depression and other mental health issues. Nutritional choices have a big influence on the remodelling of the brain and play an important part in preventing these issues.
-
A healthy, balanced diet, as recommended at every life stage, but with emphasis on DHA, EPA, B vitamins, zinc and iron.
-
DHA and EPA
—
Helps to improve memory, cognition, information processing, learning, and development of skills such as reading, writing and spelling. Low levels of DHA are linked to dyslexia and ADHD.
Found in oily fish, like mackerel, sardines, anchovies, salmon and herring, and plant based sources such as algae and seaweed.
B vitamins
—
Supports those with depression, learning difficulties, and irritability.
Found in red meat, eggs, wholegrains, and legumes.
Zinc
—
Improves symptoms of ADHD, hyperactivity and impulsivity.
Found in fish, leafy green vegetables, fruits, nuts seeds, wholegrains.
Iron
—
Improves concentration and attention.
Found in meat, legumes, dark green leafy vegetables.
Adulthood
Our brains reach their prime in our early 20s. Beyond this age, our brains start to function less effectively, and our speed of thinking is the first thing to slow down. Over time, our memory and reasoning skills will also become slower as brain connectivity reduces.
This is a natural process that happens to everyone, and while we cannot fully prevent it, improved nutrition can help to slow it down. It can also reduce risks for obesity, type 2 diabetes and heart disease.
-
A healthy, balanced diet, with an emphasis on fish, fruit and vegetables.
Reducing or avoiding processed food and refined sugars, which reduce concentration.
-
DHA and EPA
—
Helps to regulate neuro-inflammation, preserve cognitive skills, and delay dementias.
Found in oily fish, like mackerel, sardines, anchovies, salmon and herring, and plant based sources such as algae and seaweed.
Antioxidants
—
Reduces oxidative stress and cellular damage, preserving brain network connectivity.
Found in berries, wholegrains, vegetables, legumes.
Polyphenols
—
Improve cognitive performance, reduce age-related neuronal decline, protect the heart and the nervous system, and are anti-cancer.
Found in almost all fruit and vegetables.
Older age
As we age, most of us will suffer a natural cognitive decline. This decline varies on a spectrum, starting with just mild cognitive impairment (MCI). Unfortunately for some of us, this can lead to neurodegenerative disorders such as Alzheimer’s and Parkinson’s Disease. As Western populations age the incidence of these disorders is increasing exponentially. Whilst the main risk factors are age and the genes you inherit, they are also greatly influenced by your diet and other lifestyle choices. Hence it is important to understand what we can do nutritionally at this stage of life to delay cognitive decline and potentially prevent the progression of neurodegenerative disease.
-
In a similar fashion to the adult life stage particular nutrients have been documented to delay the cognitive decline accompanying ageing. It is even more important to upregulate these nutrients as the brain continues to shrink and our likelihood of neurodegenerative disease increases.
