By combining complementary proteins -- grains, like rice or bread, and plant-based protein sources, like peanuts, peanut butter or beans – you create a complete protein.
Per serving: 1,037kJ / 247kcal. 12g protein. 5g fat, of which 1.1g saturates.
P eople worried about ultra-processed foods should not dismiss beans on toast as part of a healthy, balanced diet, nutritionists have said.
Beans are incomplete proteins because they are low in one key amino acid (amino acids are used by the body to build protein) called methionine. Cereal grains—including corn, rice and wheat—are high in methionine yet lack another amino acid found in beans.
The combination of beans and rice creates a complete protein. Beans alone and rice alone both lack certain essential amino acids. If eaten together, however, each contributes what the other is missing to form a complete protein.
Avocados don't contain all the amino acids used by your body to build protein-based structures, but they contain all the essential ones. Essential amino acids must be obtained from the diet, whereas your body can make the non-essential types.
Eggs and beans are both fundamentally healthy ingredients, but if you use white bread, tinned beans and butter, you are going to be adding a lot of unnecessary sugar, salt and saturated fats to your breakfast.
Baked beans also count, so beans on toast or a jacket potato is a portion, but make sure you opt for reduced-sugar and reduced-salt versions.
“Beans and legumes are fiber-rich nutrient powerhouses and an excellent source of protein,” says Hopsecger. “One serving (1/2 cup cooked) of beans provides about 7 grams of protein, the same as 1 ounce of meat.” Beans and legumes also keep you fuller, longer because they are so rich in fiber.
With about 6 grams of protein apiece, eggs are an excellent source of this vital nutrient. But lots of other foods offer as much or more. For example, chickpeas (also known as garbanzo beans) provide nearly 8 grams of protein per 1/2 cup. People have enjoyed them since the days of ancient Egypt.
Eggs, beans and pulses count as high protein foods.
Just like hummus and whole wheat pita, peanut butter and whole wheat bread complement each other to form a complete protein. Two slices of whole wheat bread coupled with two tablespoons of peanut butter provide your body with 15 grams of protein and all nine essential amino acids.
Contains All Essential Amino Acids
The casein in Greek yogurt is a complete protein because it contains all nine essential amino acids: methionine, lysine, isoleucine, histidine, valine, tryptophan, threonine, phenylalanine and leucine.
Baked beans can be healthy as part of a balanced diet — but there are important things to note. Baked beans found in cans, such as Heinz, contain added salt and sugar that are a significant amount of the recommended daily intake.
Beans on toast are a classic for breakfast or lunch, now you know you can enjoy it without worrying about the calories too much. Plus it has nearly 12g of fibre!
The avocado, chickpeas or tomato in them will count towards your 5-a-day. A typical serving weighs around 50g (a portion of vegetables is 80g) and that includes other ingredients, so it isn't a whole portion, but every little helps. Boost your intake further by using vegetable sticks to dip.
Porridge also has the advantage of containing soluble fibre, which supports good gut and heart health. Now, if we compare this to two slices of wholegrain toast, we're also looking at around 30g of carbohydrates. This is elevated if you choose a bagel, which provides around 50g.
Porridge is an excellent choice at breakfast and is low in fats, sugar and salt. Avoid adding any sugar or honey. Fruit juice and smoothies count towards your 5 a day, although they are a source of free sugars so you should limit consumption to no more than a combined total of 150ml per day.
The benefits: Beans are a good plant-based protein source and provide a solid dose of carbohydrates for fueling. “When we break down muscle during exercise, the protein we eat helps to build it back up so we come back stronger, leaner, and faster,” Smith says.
Which foods are complete proteins? Animal proteins are complete, including meat, poultry, fish, eggs and dairy.
While naturally low in saturated fat, chickpeas are nutrient-dense. They provide nearly 20 grams of protein in a ½-cup serving. However, chickpeas aren't a complete protein because they don't provide adequate amounts of the nine essential amino acids. To make them a complete protein, eat them with wheat, oats or rice.
According to Harvard Health Publishing, all animal-based foods, including meat, dairy, and eggs, contain complete protein. The majority of plant-based protein sources, such as whole grains, legumes, seeds and nuts, spinach, broccoli, and mushrooms, are incomplete.
