Carbohydrates are a foundation of a healthy diet
Carbohydrates are indeed a foundation of a healthy diet, providing a ready source of energy for all the body's activities. According to Dr Liz Blom, a Minnesota-based nutrition and wellness coach, "Carbohydrates are needed for building nonessential amino acids that the body uses to create proteins. They also help in the processing of fat and in the building of cartilage, bone, and the tissues of the nervous system."
Carbs are often the first thing to go when people try to shape up their diets, and it's true that simple carbohydrates such as white bread, pasta, cake, and other sugar-filled refined carbohydrates can hinder weight-loss efforts. However, it is important to distinguish between simple and complex carbohydrates. Complex carbohydrates, such as fibre-rich fruits and vegetables, whole grains, legumes, and beans, provide the body with energy and many other nutrients. They are also digested more slowly, making people feel full for longer, which can aid in weight control. On the other hand, simple carbohydrates, such as soda, cookies, juice, and other baked goods, often contain large amounts of sugars and fats, which can lead to weight gain and diabetes.
The amount of carbohydrates a person should consume depends on various personal factors, including age, sex, body type, height, weight, weight history, and activity level. The Dietary Guidelines for Americans recommend that carbohydrates provide 45% to 65% of the daily calorie intake for all age groups and sexes. The Institute of Medicine suggests a minimum of 130 grams of carbohydrates per day for adults, while other sources recommend 40% to 75%. In Australia, the average adult's daily requirement is 8700kJ (about 2100 calories), as prescribed by the Australia New Zealand Food Standards Code.
It is important to note that if you are trying to lose weight, it is not necessary to cut out all carbohydrates. Instead, focus on loading up on wholesome varieties of carbohydrates, like whole grains, fruits, vegetables, legumes, and even dairy products, and keep your portions in check. These healthy sources of carbs are packed with fibre, which fills you up faster and curbs your appetite better than simple carbohydrates.

How many carbs to eat depends on age, sex, weight, and activity level
The number of carbohydrates a person should consume depends on a variety of personal factors, including age, sex, weight, and activity level. The average adult's daily requirement is 8700 kJ (about 2100 calories), but this may vary depending on individual energy needs.
Age plays a role in determining carbohydrate intake. For instance, individuals above 50 should reduce their kilojoule intake, with females decreasing by 500 kJ and males by 1300 kJ per day. Younger males (under 31) need about 800 kJ more than females of the same age group.
Sex is another factor influencing carbohydrate consumption. Generally, males require more carbohydrates than females due to differences in body composition and energy requirements.
Weight also impacts the number of carbohydrates an individual should eat. Those with higher weights or looking to lose weight may aim for a lower carbohydrate diet, typically defined as consuming less than 20 to 120 grams of carbohydrates per day. However, it's important to note that completely eliminating carbohydrates from the diet may negatively affect overall health.
Activity level is a crucial consideration in determining carbohydrate intake. Individuals with higher activity levels, such as those engaging in intense or very intense exercise, will generally require more carbohydrates to fuel their physical endeavours.

Carb sources: whole grains, fruits, vegetables, legumes, and dairy
Carbohydrates are essential for a healthy diet, providing energy and helping the body process fat and build cartilage, bone, and the tissues of the nervous system. When deciding how many carbs to eat, it's important to consider individual factors such as age, sex, height, weight, activity level, and genetics. While there is no one-size-fits-all answer, a rule of thumb is that carbs should make up about 45% of your daily calories.
Now, let's delve into some healthy sources of carbohydrates, including whole grains, fruits, vegetables, legumes, and dairy:
Whole Grains
Whole grains, such as oats, rye, brown rice, and whole wheat, are excellent sources of carbohydrates. They contain all three parts of the grain—the bran, germ, and endosperm—which makes them more nutritious than refined grains. Whole grains are packed with vitamins, minerals, antioxidants, and dietary fiber. They have been linked to a reduced risk of heart disease, type 2 diabetes, and cancer.
Fruits
Fruits are well-known for their sweetness and carbohydrate content. While some fruits are higher in carbs than others, they are all nutrient-rich and offer various health benefits. For example, strawberries and cantaloupe are excellent sources of vitamin C, while oranges provide a good balance of carbs and vitamin C. Watermelon is a refreshing, low-carb option, and peaches offer a sweet treat with 15 grams of carbs per medium peach.
Vegetables
Vegetables are a cornerstone of a healthy diet and can provide a good amount of carbohydrates. Low-carb vegetable options include asparagus, spinach, garlic, and green beans. Mushrooms, while not always classified as vegetables, are a plant-based source of vitamin D and B vitamins. Cauliflower has gained popularity as a low-carb alternative to bread or rice, and it also provides a good amount of vitamin C.
Legumes
Legumes, such as beans, lentils, peas, and soybeans, are an excellent source of carbohydrates. They are known for their high protein and fiber content, as well as important vitamins and minerals. Legumes have been linked to improved blood sugar management and a reduced risk of diabetes. For example, black beans have a lower glycemic index than many other high-carb foods, causing a smaller rise in blood sugar after a meal.
Dairy
Dairy products, such as milk, yoghurt, and cheese, also contribute to your daily carbohydrate intake. While they are not typically the first food group that comes to mind for carbs, they can be part of a balanced diet that includes healthy sources of carbohydrates.

Avoid simple carbs: soda, cookies, juice, and other baked goods
Carbohydrates are a major macronutrient and one of the body's primary sources of energy. While some weight loss programs advocate for cutting carbs, the key is to find the right carbs rather than avoid them altogether.
Simple carbohydrates are digested quickly and cause a rapid spike in blood sugar levels. They are typically found in processed foods or those with added sugars, such as soda, cookies, and other baked goods. These added sugars provide empty calories and can lead to weight gain. They also lack vitamins, minerals, and fiber, which are essential for a healthy body.
It is best to avoid simple carbs like soda, cookies, and other baked goods. These often contain high amounts of added sugars, which provide extra calories without any additional nutritional value. Instead, opt for whole fruits rather than fruit juice. Whole fruits contain more dietary fiber and are a healthier option.
Additionally, be cautious of sports drinks, which often contain large amounts of added sugar. While they are marketed as performance-enhancing beverages, evidence of their effectiveness is limited.
When it comes to baked goods, opt for complex carbohydrates instead. These are digested more slowly and provide a gradual release of glucose into the bloodstream, keeping you energized for longer. Examples of complex carbohydrates include whole grains, fruits, vegetables, legumes, and even dairy products.
In summary, while it's important to watch your carb portions, it's crucial to focus on choosing quality foods. Opt for complex carbohydrates and whole foods that provide essential nutrients, fiber, and a more stable source of energy.

Low-carb diets: less than 20 to 120 grams of carbs per day
Low-carb diets are defined as those that contain less than 20 to 120 grams of carbohydrates per day. However, the optimal carb intake varies between individuals, depending on factors such as age, sex, body composition, activity levels, metabolic health, and personal preference. For instance, older individuals may need to reduce their kilojoule intake, while males under 31 years of age typically require more kilojoules.
The benefits of a low-carb diet include reduced appetite, lower calorie intake, and weight loss. A study comparing low-carb and low-fat diets found that participants on the low-carb diet experienced greater weight loss for up to a year compared to those on a low-fat diet. Additionally, a low-carb diet can lead to a reduction in visceral fat, which is strongly associated with many diseases.
It is important to note that not all carbs are created equal. Complex carbohydrates, such as fibre-rich fruits and vegetables, whole grains, legumes, and beans, provide the body with energy and essential nutrients. These foods are also digested more slowly, leading to a prolonged feeling of fullness, which can aid in weight control. On the other hand, simple carbohydrates, such as soda, cookies, juice, and baked goods, are high in sugars and fats and may contribute to weight gain and health issues like diabetes.
When considering a low-carb diet, it is essential to focus on the quality of the foods you eat. Eating a variety of nutrient-dense, whole foods ensures you meet your nutrient requirements and maintain adequate energy intake. Additionally, it is crucial to pay attention to your body's response and make adjustments accordingly. For personalised advice, consulting a dietitian or registered nutritionist is recommended.
