The right amount of protein for you
- women need 0.75 grams per kilogram (so if you weigh 65 kilograms, you need 49 grams of protein every day)
- men need 0.84 grams per kilogram (so if you weigh 75 kilograms, you need 63 grams of protein every day).
Not all food proteins are the same.
There are 20 amino acids (or building blocks), and nine of these are called ‘essential’. This is because your body cannot make them (although it can make the other 11).
High protein foods
- lean meats – beef, lamb, veal, pork, kangaroo
- poultry – chicken, turkey, duck, emu, goose, bush birds
- fish and seafood – fish, prawns, crab, lobster, mussels, oysters, scallops, clams
- dairy products – milk, yoghurt (especially Greek yoghurt), cheese (especially cottage cheese)
- nuts (including nut pastes) and seeds – almonds, pine nuts, walnuts, macadamias, hazelnuts, cashews, pumpkin seeds, sesame seeds, sunflower seeds
- legumes and beans – all beans, lentils, chickpeas, split peas, tofu.
Getting more protein into your day, naturally.
If you’re looking for ways to get more protein into your diet, here are some suggestions:
- Try a peanut butter sandwich! Remember to use natural peanut butter (or any other nut paste) with no added salt or sugar.
- Low-fat cottage or ricotta cheese is high in protein and can go in your scrambled eggs, casserole, mashed potato or pasta dish. Or spread it on your toast in the morning.
- Nuts and seeds are fantastic in salads, with vegetables and served on top of curries. Try toasting some pine nuts or flaked almonds and putting them in your green salad.
- Beans are great in soups, casseroles, and pasta sauces. Try tipping a drained can of cannellini beans into your favourite vegetable soup recipe or casserole.
- A plate of hummus and freshly cut vegetable sticks disappear quickly! Or spread hummus on your sandwich for an extra protein hit at lunchtime.
- Greek yoghurt is a protein-rich food that you can use throughout the day. Dollop, some on your favourite breakfast cereal, put a spoonful on top of a bowl of pumpkin soup or serve it as a dessert with some fresh fruit.
- Eggs are a versatile and easy option. Better Health Channel has some good ideas on how to use eggs every day.
Protein shakes, powders and supplements
If you’re not getting enough protein in your diet, are protein shakes, powders and supplements a good idea? Unless you are exercising or training at the level of an athlete, the simple answer is probably not.
Most of us get more than enough protein through the food we eat. And any protein we eat on top of what our body needs will either be excreted from our body as waste, or stored as weight gain! Also, having too much protein on top of what our body needs can be damaging to our kidneys.
The best way for you to get the protein you need is to eat a wide variety of lean protein as part of a balanced diet. But if you are still interested in using protein shakes, powders and supplements, the best place to start is to talk to your doctor.
The dangers of a high protein diet
Most Australians eat far more protein than they need. And there are some dangers associated with eating a high protein diet:
- Some protein-rich foods (like red meat and full-fat dairy products) may increase your risk of heart disease, as they are high in cholesterol-raising saturated fat.
- It is also thought that a diet high in red meat – particularly deli meats such as ham, bacon and salami – may increase your risk of bowel cancer.
- High protein diets often restrict your carbohydrate intake. And this can mean we miss out on important vitamins and minerals and lead to problems associated with not getting enough fibre (such as bad breath, headache and constipation).
- And if you drastically reduce your carbohydrate intake, your body will go into a state called ‘ketosis,’ meaning it burns fat for energy rather than carbohydrate. While that sounds appealing, it often leads to side effects like moodiness, bad breath, difficulty concentrating, and low blood sugar levels. Your body may also start to convert protein into carbohydrates to feed the brain, and in the long term may also put you at risk of conditions like heart and kidney disease.
- A high protein diet may also adversely affect your kidney function if you have kidney disease.
- Protein is an important nutrient that helps your body grow and repair cells.
- Most Australians eat more than enough protein. But if you are vegetarian or vegan, you may not be getting enough protein. Or you may not be eating enough of the right type of protein.
- The best way to get the right amount of protein – and the right type –is to eat a wide variety of protein-rich foods as part of a balanced diet.
