A little bit of fun science about proteins before we go into discussing foods high in protein!
Protein is a molecule made up of amino acids. It’s a nutrient your body needs to grow and repair cells. Proteins are the building blocks of your life. Every cell in your body contains protein. You need proteins because your body cannot produce essential amino acids on its own.
Proteins are called workhorses of your cell, because they compose structural and motor elements in your cell and they serve as the catalysts for almost every biochemical reaction that occurs in your body.
You need protein in your diet to help your body repair your cells and create new ones. Protein is also essential for growth and development in children and pregnant women.
Protein is an essential nutrient that helps build muscle tissue and maintain bone density. It also provides energy for daily activity.
The best source of protein is animal products, which include meat, poultry, fish, dairy and eggs. Plant-based protein sources include beans, nuts, seeds, soybeans, tofu, and other legumes.
High-protein diets favourably include large amounts of protein and only a small amount of carbohydrate. And, protein foods are broken down into amino acids during digestion. Your body needs a number of amino acids in large amounts to maintain good health.
How Much Protein You Need Daily
Protein is an essential macronutrient, and since your body cannot produce the macronutrients on its own, it’s important to get them through your diet.
The National Academy of Medicine recommends that adults get a minimum of 0.8 grams of protein for every kilogram of body weight per day, or just over 7 grams for every 9.07185 kilogram of body weight.
The acceptable protein intake can range between 10% and 35% of calories each day.
Protein deficiency and malnutrition can contribute to the loss of your muscle mass and your decreased immunity, weakening of your heart and your respiratory system.
Types of Protein Good For Your Health
When we eat foods high in protein, we also end-up eating everything that comes with them: the different fats, fiber, sodium, etc. It’s this protein package that’s likely to make a difference to your health.
Research data suggests that it’s the source of protein (the protein package, as it is called) rather than the amount of protein that can make a difference for your health.
Healthy protein sources like beans, nuts, fish and poultry can make a positive difference to your health, while eating red meat and processed meat can increase the risk of several diseases and even lead to premature death.
And there’re complete and incomplete proteins.
Complete Proteins
If the protein you eat has all the 9 types of amino acids, it is called a “complete protein.” Some sources of complete proteins are:
Incomplete Proteins
If the protein you eat doesn’t have all the nine types of amino acids, it’s called an “incomplete protein.” Some sources of incomplete proteins are:
Now, let’s see foods that are high in protein.
1. Milk
Milk is a good source of high quality protein. It’s also high in vitamins ((vitamin B2) and minerals, such as calcium and phosphorus. Vitamin B2 helps break down proteins, fats and carbohydrates. It plays a vital role in maintaining the body’s energy supply.
If you’re lactose-intolerant, you can buy lactose-free daily products, such as lactose-free milk or cheese (cheddar cheese) from your favourite online store. If you want to know more about food intolerance and how to deal with it, please refer to our exclusive blog post on the subject.

2. Yogurt
Yogurt is high in protein, with about 12 grams per 8 ounces (227 grams, to be precise). Protein supports your metabolism by increasing your energy expenditure or the number of calories that you burn in a the day. Yogurt, especially greek yogurt, can potentially influence your appetite management and delay feelings of hunger, which can contribute to your weight loss.
Yogurt can help your appetite regulation, as it increases the production of leptin hormones that tell your brain that you’re full. It may also help you reduce the number of calories you consume, which might aid your weight loss.
“Protein content in Yogurt: 245 grams of plain yogurt churned from whole milk contains about 8.5 grams of protein.”
3. Eggs
Eggs are a complete protein and are rich with vitamins and minerals. Eggs are low carbs and calorie, and are a cheap and healthy source of protein. One egg provides 6 to 8 grams of protein with just 70 calories.
Dietary cholesterol level in eggs has a very minimal impact on serum cholesterol levels or blood cholesterol levels, so they’re safe for your daily consumption. However, it’s recommended that you limit eating one egg per day.
Always eat egg with its yolk, a rich source of nutrition, which include vitamin D, omega-3 fatty acids, B vitamins and choline. Studies have clearly shown that whole eggs are very healthy for most people and may actually help prevent chronic diseases.
“Protein content in Eggs: One egg (50 grams) provides 6.3 grams of protein.”
4. Chicken
Chicken is a great choice for your increased protein intake. It’s a lean protein with 25 g in just 4 ounces. Chicken also provides a variety of B vitamins and minerals such as zinc and selenium.

Benefits of a Higher Protein Diet
Eating more protein is really good for you. It can help you lose weight and build muscle. Here’s how:
- Protein keeps you feeling full longer. So you won’t get as hungry or have as many cravings. It also gives your metabolism a little boost to burn more calories.
- Protein builds and repairs your muscles after working out. Even if you’re trying to slim down, it preserves your lean muscle.
- A protein-rich meal satisfies you way more than a carb-heavy one. Protein crushes hunger pangs, making it easier to stick to healthy foods.
- Studies show a high-protein diet may lower risks for heart disease, diabetes, and some cancers. Awesome!
- protein is great for overall health. It strengthens your immune system, balances hormones, and builds strong bones. It’s like a superhero nutrient!
Of course, don’t overdo just protein. Eat plenty of fruits, veggies, whole grains, and good fats too. But if you want to level up your fitness and health, packing in more protein is a smart move.
Understanding Daily Protein Requirements
Daily protein needs vary based on several factors:
- Body weight: Larger people generally require more protein.
- Activity level: Athletes and highly active individuals need more protein for muscle repair and recovery. Endurance athletes may need 1.2-2.0 g/kg body weight, while strength athletes may need 1.6-2.2 g/kg.
- Age and health status: Protein requirements increase during pregnancy, breastfeeding, illness, or injury to support growth, healing, and immune function.
The general recommended dietary allowance (RDA) for protein is 0.8 g/kg body weight per day for healthy adults. However, excessive protein intake provides no additional benefits and may strain the kidneys. It’s best to consult a healthcare professional to determine your specific protein needs based on your individual circumstances.
To help you understand how protein needs can differ based on body weight and activity level, here’s a text table illustrating the recommended protein intake for different individuals:
| Body Weight (kg) | Sedentary (g/kg) | Endurance Athletes (g/kg) | Strength Athletes (g/kg) |
| 50 | 40-45 | 60-100 | 80-110 |
| 60 | 48-54 | 72-120 | 96-132 |
| 70 | 56-63 | 84-140 | 112-154 |
| 80 | 64-72 | 96-160 | 128-176 |
It’s important to remember that these values are rough estimates and should be used as a starting point. Individual protein needs may vary, and it’s best to consult with a healthcare professional or registered dietitian for personalized guidance.
Incorporating High-Protein Foods into Meals
Kickstart your morning right with a protein-packed breakfast. Greek yogurt topped with fresh fruit and chia seeds, a veggie-filled omelet, or a protein smoothie are all great options.
For lunch and dinner, add in lean protein sources. Toss some grilled chicken or black beans into your salad. Stir-fry tofu or lean beef with veggies over brown rice or quinoa. Or make lettuce wraps stuffed with turkey and avocado.
Don’t forget snacks! Grab a spoonful of peanut butter or cottage cheese to fill you up between meals.
With a few simple swaps, it’s easy to get more protein into your daily diet. Your body will thank you for the energy boost.
Conclusion
Incorporating high-protein foods into your diet can have numerous benefits, from supporting muscle growth and recovery to promoting satiety and weight management. Understanding your daily protein requirements and including a variety of protein sources in your meals is key to maintaining a balanced diet. Whether you prefer plant-based or animal-based proteins, there are plenty of delicious options to choose from. By making informed choices and incorporating high-protein foods creatively into your meals, you can optimize your nutrition and overall well-being. Remember, balance and variety are essential for a healthy diet rich in protein.
