high and low glycemic index foods



Presse Santé

Foods with a high glycemic index (GI) raise blood sugar quickly and can cause health problems if eaten in excess. A low GI diet can help prevent and control diabetes and cardiovascular disease. One can also control their weight through a low GI diet as part of an overall approach to healthy eating.
This article explains what the GI is and which foods have a high or low GI. It also highlights the benefits of a low GI diet and gives an example of a low GI meal plan.

What is the glycemic index?

The glycemic index (GI) is a measure that ranks carbohydrate-containing foods based on their effect on a person’s blood sugar levels. Foods are classified from 1 to 100 and pure glucose is used as a reference, whose GI is 100.

The GI of foods is classified into three categories: low, medium or high:

Low GI: 55 or less
Average GI: 56-69
High GI: 70 or more

Glycemic load (GL) is another measure that some experts say gives a more realistic picture of the effect of foods on blood sugar. The GL takes into account the amount of carbohydrates in a serving of food, as well as its GI. The glycemic index can help people make healthy food choices and control the amount of sugar and carbohydrates they eat. This approach can help a person control their weight or a health condition such as diabetes.

Factors that influence the glycemic index of foods

Several factors influence how quickly a particular food raises a person’s blood sugar level. These factors may include:

– the degree of refinement of the carbohydrate
– the physical and chemical structure of the food
– the cooking method
– the amount of fiber in the food
– the amount of proteins, fats and acids that the food contains.

Generally speaking, refined and processed carbohydrates break down into glucose faster. Foods that contain fiber, protein, and fat release glucose more slowly and therefore have a lower GI. Longer cooking times can break down foods, meaning the person eating those foods absorbs the glucose faster.

High GI foods to avoid

A person who wants to control their weight or diabetes can find the GI of foods by consulting the international tables of glycemic index and glycemic load values. According to this table, the following foods have a high GI:

– white bread and wholemeal bread
– White rice
– breakfast cereals and cereal bars
– cakes, cookies and sweets
– potatoes and fries
– the chips
– fruits such as watermelon and pineapple
– sugary dairy products such as fruit yoghurts.

People following a low GI diet can eat foods with a medium GI of 56 to 69, but less often than foods with a low GI. Medium GI foods include rye bread and raisin bran cereals.

Benefits of a low glycemic index diet

High GI foods tend to cause a person’s blood sugar levels to rise, causing the body to produce more insulin. Once insulin has moved glucose into cells, blood sugar levels can drop, leading to low energy or low mood. In addition to these short-term effects, blood sugar dysregulation can have longer-term health effects, such as insulin resistance and diabetes. There is consensus that low GI and low GL diets are relevant for the prevention and control of diabetes, coronary heart disease, cancer, and possibly obesity. A low GI diet can be beneficial and help prevent certain health problems.

Knowing the GI of foods can help people control their blood sugar levels and prevent or delay diabetes-related complications. Low GI diets can help people with diabetes lower their blood sugar levels.

In addition, low GI diets may reduce long-term markers of glycemic control, body weight, and fasting blood sugar in people with prediabetes or diabetes. A low GI diet can also help fight gestational diabetes. This is a condition where a person develops high blood sugar during pregnancy, which usually resolves after delivery. According to a 2016 meta-analysis, a low GI diet may reduce the risk of macrosomia in people with gestational diabetes. This is a condition that results in larger than average babies, which can lead to many short-term and long-term complications for both the birthing person and the baby.

In addition to controlling glucose and insulin metabolism, a low-GI, energy-restricted diet can also help reduce body weight.

High GI foods can also affect mood and energy. A 2016 study indicates that, in healthy and overweight adults, consuming a high GI diet results in a 38% higher chance of depressive symptoms and a 26% higher fatigue and inertia score. A 2019 meta-analysis indicates a relationship between high GI and GL diets and coronary heart disease. Another meta-analysis from 2019 indicates an association between a high GI diet and colorectal, bladder and kidney cancers.

Low GI meal plan example

Here are examples of meal options for someone on a low GI meal plan:

breakfast options

Some low GI breakfast options include:

Scrambled eggs with smoked salmon
buckwheat pancakes with berries

lunch options

Low GI lunch options may include

chicken with mango and almonds on rye bread
cauliflower and celery soup

dinner options

Low GI dinner options may include

leg of lamb, peas and mint
Indian Spicy Vegetable and Cheese Parcels

snack options

Low GI snack options may include

a slice of cinnamon almond bread
roasted soy nuts

When planning meals, it can be helpful to count carbohydrates. By managing carbohydrates using the GI, people can better control their blood sugar.

Disadvantages of a low GI diet

Following a low GI diet can be a bit tricky. You need to know the GI of all the foods on your plate, which can be problematic when a meal has many ingredients. Following a low GI diet can limit a person’s options when eating out. A person should also consider the amount of fiber, fat, and protein in a meal to see how the meal as a whole may affect their blood sugar levels.

A 2015 study advises people to consider a low GL and low GI in the context of an overall healthy diet. Fiber and whole grains are essential components of a healthy diet and may predict health outcomes better than GI. Therefore, it may be more important for people to know the GI of foods while maintaining a balanced and healthy diet.


A person may want to follow a low GI diet to control their weight or health status. This can be done by learning about the GI of foods and making a meal plan. You should also consider other aspects of a balanced and healthy diet, such as fiber and whole grains, in this planning. Low GI diets may be beneficial in preventing and managing insulin resistance, diabetes, and cardiovascular disease. However, planning a low GI diet can be complex, so a person may want to consider seeking the advice of a dietitian.

Follow the sports diet to lose weight in a healthy and sustainable way



Presse Santé

The sports diet is the newest and most promising weight loss method on the market. Unlike other diets that are based on caloric restriction or special food combinations, the sports diet focuses on the level of activity. The theory behind this is that if you are more active, you will naturally eat less.

Although there is no single approach to fitness and weight loss, the sports diet can be a good option for those who want to lose weight without giving up their favorite foods or resorting to extreme measures. But what is this? And how can you start using it today? Read on to find out.

What is the principle of the sports diet?

The Sports Diet is a nutrition plan specifically designed to meet the demands of sports training and competition. The key principle of the sports diet is to ensure that the athlete’s body has the right mix of nutrients to support optimal performance.

To achieve this, the sports diet emphasizes foods rich in complex carbohydrates, lean proteins and healthy fats. These nutrients provide the energy and substrates necessary for muscle contraction, proper cell function and recovery after exercise. In addition, the sports diet also includes foods rich in vitamins, minerals and antioxidants, which help protect cells from damage and strengthen the immune system. Used correctly, the sports diet can be a powerful tool to optimize sports performance.

Who can follow a sports diet?

Many people think that the sports diet is only for athletes. However, the principle of the sports diet can be applied to anyone who wants to improve their health and physical performance. Anyone who wants to optimize their performance in a sport can benefit from a sports diet. This type of diet is designed to help the body function at its best by providing the right combination of nutrients. The details of a sports diet vary according to individual needs, but there are common elements.

For example, many people need to consume more protein than the average person to help repair and build muscle tissue. They may also need to increase their carbohydrate intake to fuel their activity level. A sports diet can help ensure that a person receives all the nutrients he needs to perform at his best.

Some recommend the sports diet to lose weight in a healthy and lasting way.

Anyone who has ever dieted knows that there are many different approaches to losing weight. Some swear by low-carb diets, while others believe cutting out sugar is the key to losing weight. But what if there was a way to lose weight by eating like a professional athlete? This is where the sports diet comes in.

Although not for everyone, the sports diet can be an effective way to lose weight, build muscle, and improve athletic performance. This diet is based on the principle of eating for sustenance, rather than pleasure, and thus eliminates most processed foods and junk food. Instead, it is based on 100% healthy and wholesome meals that will provide sustained energy throughout the day. Although it takes a while to get used to this new way of eating, many people find the results worth it.

Losing 9 kilos in 15 days, does it tempt you?

The sports diet is based on the principle that by eating the right foods, you can increase your metabolism and burn more calories. It is rich in protein and fiber to increase the feeling of satiety and reduce appetite, thus preventing the risk of overeating.

With this diet, you should strive to follow two distinct phases, each with its own set of challenges. During the offensive phase, you should consume 3 meals with a large amount of protein while eliminating carbohydrates and fats from your diet. This can be difficult to do, especially if you are used to eating high-carbohydrate foods.

During the stabilization phase, you should carefully monitor your caloric intake and limit yourself to 1,200 cal for the first few days and then allow yourself 1,500 cal moving up to 1,800 cal. The objective of this second phase is to help your body to better assimilate all the nutrients ingested during the previous week. For this program to work, you must be very disciplined, both in food and in sports. But if you stick with it, you’ll be rewarded with a dream body!

The 7 secrets of the Okinawan diet



Presse Santé

Intrigued by the longevity of the people of Okinawans, Japan, researchers have studied their diet to try to discover its secrets. Here are 7 of the most interesting findings on the Okinawan diet.

The Okinawan diet is often touted as the secret to a long and healthy life. And it is not for less: the Okinawa region in Japan has one of the highest concentrations of centenarians in the world. While many factors contribute to the longevity of Okinawans, their diet is considered one of the key elements. But what exactly do they eat?

  1. They eat a lot of sweet potatoes.

One of the most interesting findings that researchers have made is that Okinawans eat a lot of sweet potatoes. Sweet potatoes are a good source of vitamin A, which is important for healthy skin and eyesight. They are also a good source of fiber, which helps regulate digestion. Plus, sweet potatoes are low in calories and fat, making them an ideal food for people trying to lose weight. While there is no single answer to the question of why Okinawans live so long, the high consumption of sweet potatoes is certainly a contributing factor.

  1. They eat small portions.

Okinawans generally eat small meals, taking time to savor each bite, stopping when they feel satisfied rather than full. This helps prevent overeating and maintains a healthy weight. Additionally, Okinawa is known for its abundance of fresh fruits and vegetables, which are packed with essential nutrients. The Okinawan diet also includes plenty of fish, which is a good source of heart-healthy omega-3 fatty acids. Combined with moderate physical exercise and strong social connections, it’s no surprise that Okinawans enjoy such long and healthy lives.

  1. They eat a lot of vegetables.

Vegetables make up a large part of the diet for Okinawans, who typically eat more than 5 servings a day. This is in contrast to the Western diet, which is high in meat and processed foods. Okinawans’ high consumption of vegetables is probably one of the reasons why they enjoy such a long life. Vegetables are full of essential nutrients for good health and are low in calories and fat. They also contain antioxidants, which can help protect against disease. All of these factors contribute to a longer and healthier life.

  1. They eat fish regularly.

Fish is an excellent source of protein, omega-3 fatty acids, and other essential nutrients for good health. It’s also low in calories and fat, making it a smart choice for people watching their weight. Furthermore, fish is known to be good for the heart and brain, two organs that tend to deteriorate with age. Not surprisingly, studies have shown that people who eat fish regularly tend to live longer than those who don’t.

  1. They consume moderate amounts of pork.

Although pork is not as prominent in the Okinawan diet as it once was, it is still eaten in moderation. While pork is known to be a significant source of calories in many traditional Japanese diets, Okinawans eat only small amounts. They prefer to eat a lot of vegetables and fish. This diet is believed to be one of the reasons Okinawans have such low rates of heart disease and obesity.

  1. They drink green tea every day.

Green tea is rich in antioxidants, which help protect cells from damage. It also contains compounds that have been shown to boost metabolism and promote weight loss. Additionally, green tea has been linked to a lower risk of heart disease and various types of cancer. Considering all of these health benefits, it’s no surprise that green tea is a staple of the Okinawan diet.

  1. They practice “hara hachi bu”.

A Japanese saying that means they eat until they are only 80% full. And research has shown that this practice can lead to a longer life.

One of the reasons that hara hachi bu can be beneficial is that it can help prevent overeating. And we know that overeating can lead to a host of health problems, including obesity, heart disease, and diabetes. By eating less, Okinawans can avoid these problems.

Another reason is that it gives the body time to properly digest food. When we eat too much, our body has a hard time digesting all the food. This can lead to indigestion, bloating, and other problems. Conversely, when we only eat until we are 80% full, our body finds it easier to digest food.
