Protein is used to grow and maintain tissue in the body, so it
is a vital part of everyone's diet. Red meat contains a lot of
protein but it is also high in saturated fat. Fortunately, there
are many healthy sources of protein, including lean chicken, pulses and nuts.
When people start eating a healthy diet, they are often
concerned about levels of protein. One of their main concerns
can be the fact that whilst red meat is high in protein, it should only be consumed in limited quantities, as it also contains a lot of saturated fat.
However, there's no need to worry about your diet lacking in
protein, as there are plenty of healthy vegetables, nuts and
seeds that contain this vital nutrient.
What protein does
Your body needs protein to grow and maintain tissue. Muscles,
internal organs, blood, skin and hair all require protein for a
healthy structure. You also need protein to repair any damage
that your body has sustained. For example, collagen is a protein
that makes up scar tissue and strengthens the walls of arteries.
Vital hormones such as insulin and thyroxine are made of
proteins. Insulin helps maintain blood-sugar levels, while
thyroxine helps control metabolism and body temperature.
Digestive enzymes that break down food are also made of
proteins, as are the antibodies your immune system needs to
fight off infection.
Proteins really are the building blocks of life.
Good sources of protein:
With red meat containing saturated fat and processed meats
often containing potentially harmful additives, it's just as
well there are many other, healthier sources of protein.
Lean chicken and turkey have a high protein content. But be
sure to buy organic poultry, because factory farmed meats may
contain antibiotic and hormone residues. You can also be sure
that free range chickens and turkeys have lived a good life.
Be sure to grill or stir-fry chicken when serving it – it
certainly won't count as a good source of protein if it's
deep-fried!
Oily fish – such as salmon, sardines and herring – is a great
source of protein, and it has the bonus of containing high
levels of Vitamin A. Eating oily fish also helps combat heart
disease and arthritis.
Mung beans, lentils and chickpeas can be combined to make the
base for a delicious, protein-rich curry. If you want a healthy
snack that is full of protein and will give you a satisfying
feeling of fullness between meals. Why not try a handful of
cashew nuts, walnuts, hazelnuts, raw shelled hemp seeds or flax
seeds.
The key to maintaining a healthy level of protein is to eat a
wide variety of nourishing, protein-rich foods. Try different
food combinations to get the optimum level of essential
nutrients.
