Nutritive components of a diet are those that provide energy or calories to the body. They include carbohydrates, proteins, fats, vitamins, and minerals. These components are essential for the body to function properly and maintain good health. A balanced diet includes these nutritive components in the right portions, along with non-nutritive components such as water, fiber, and plant compounds. While non-nutritive components do not provide energy, they are still necessary for the body and can have health benefits, such as reducing the risk of certain diseases.

What You'll Learn
Carbohydrates
Your body needs to break down starches into sugars to use them for energy. Diets high in fibre have many health benefits, including helping you feel full and making you less likely to overeat. However, low-carb diets can limit your fibre intake and be challenging to maintain in the long term.
There are three types of carbohydrates: simple carbohydrates and complex carbohydrates, which are made up of many simple sugars, and fibre. While simple carbs are not necessarily "bad," complex carbs provide more nourishment to your body. As such, it is recommended to eat plenty of nutrient-rich complex carbohydrates and consume simple carbohydrates in moderation.

Fats
Nutritive components of a diet are those that provide energy or calories to the body. Fats are one such nutritive component.
There are two main types of fat: saturated and unsaturated. Saturated fats are found in animal products, such as butter, cheese, whole milk, ice cream, cream, fatty meats, and some vegetable oils like coconut, palm, and palm kernel oil. These fats are solid at room temperature and can increase your LDL (bad) cholesterol levels, which can lead to a higher risk of heart attack, stroke, and other major health problems. Therefore, it is recommended to keep saturated fats to less than 6% of your total daily calories.
On the other hand, unsaturated fats, which include monounsaturated and polyunsaturated fats, can help lower your LDL cholesterol levels. Monounsaturated fats include olive and canola oil, while polyunsaturated fats contain omega-3 and omega-6 fatty acids, which are important for brain function and skin and hair growth. Fatty fish, such as tuna, salmon, mackerel, whitefish, herring, and sardines, are excellent sources of omega-3 fatty acids. Plant-based foods like walnuts, flax seeds, chia seeds, soybeans, avocados, and olives are also good sources of healthy fats.
To incorporate more healthy fats into your diet, you can cook with vegetable oils, limit saturated fats, avoid trans fats, and aim to eat at least one good source of omega-3 fats each day. Trimming the fat and skin on meats, baking or grilling instead of frying, and choosing lean meats are also ways to reduce your consumption of unhealthy fats. Reading nutrition labels is important to help you make informed choices about the types and amounts of fat in your diet.

Proteins
Nutritive components of a diet are the parts of food that provide energy or calories to the body. Protein is one such nutritive component. Protein is a nutrient that the body needs to grow and repair cells, and to function properly. It is made up of building blocks called amino acids. There are about 20 different amino acids that link together in different combinations. The body uses them to make new proteins, such as muscle and bone, and other compounds such as enzymes and hormones. It can also use them as an energy source.
Some amino acids can be made by the body, and there are 11 of these non-essential amino acids. However, there are 9 amino acids that the body cannot make, and these are known as essential amino acids. Essential amino acids must be supplied by food and are found in animal sources such as meats, milk, fish, and eggs. They are also found in plant sources such as soy, beans, legumes, nut butters, and some grains (such as wheat germ and quinoa).
The amount of protein you need in your diet depends on your overall calorie needs. The daily recommended intake of protein for healthy adults is 10% to 35% of your total calorie needs. One gram of protein supplies 4 calories. As such, a person on a 2000-calorie diet could eat 100 grams of protein, or 400 calories from protein, supplying 20% of their total daily calories.
It is important to note that very high-protein diets are not recommended. While eating a relatively high-protein diet may be beneficial for the heart, it is important that the protein comes from a healthy source. For example, a 20-year study of over 80,000 women found that those who ate low-carbohydrate diets that were high in plant-based sources of fat and protein had a 30% lower risk of heart disease compared to women who ate high-carbohydrate, low-fat diets. However, eating a low-carbohydrate diet high in animal fat or protein did not offer such protection. Another study found that diets that replaced red meat with healthy plant proteins led to decreases in risk factors for cardiovascular disease.
If you are looking to increase your protein intake, there are many options. For example, you could try a peanut butter sandwich, using natural peanut butter with no added salt, sugar, or other fillers. Low-fat cottage or ricotta cheese is high in protein and can be added to scrambled eggs, casseroles, mashed potatoes, or pasta dishes. It can also be spread on toast in the morning. Nuts and seeds are also a great source of protein and can be added to salads, vegetables, or curries. Beans are another good source of protein and can be added to soups, casseroles, and pasta sauces.

Vitamins
Nutritive components of a diet are those that provide energy or calories to the body. Vitamins are essential micronutrients that the body requires to function, grow and repair itself. Vitamins are organic compounds that are needed in small amounts to maintain overall health.
It is important to note that while vitamins are essential, they should be obtained primarily from food sources rather than supplements. This is because foods contain a host of other beneficial nutrients, such as fibre, antioxidants, and carotenoids, which are not typically found in isolated vitamin supplements.
In some cases, vitamin supplements may be necessary to address specific deficiencies. For example, vitamin D and calcium deficiencies are common, and supplements may be recommended if these nutrients are not adequately obtained through diet alone.

Frequently asked questions
Nutritive components of a diet are the components that provide energy or calories to the body. They include carbohydrates, proteins, and fats, also known as macronutrients.
Some examples of nutritive components of a diet include carbohydrates, proteins, and fats. These are the macronutrients that the body needs in large proportions. Other nutritive components are vitamins and minerals.
Nutritive components of a diet provide energy or calories to the body. They are essential for the body's energy, carbohydrates, and nourishment. Non-nutritive components, on the other hand, do not have the same nutritional value but are still necessary for the body in small quantities. Examples of non-nutritive components include water, fibres or roughage, and plant compounds.
