All fruits are not created equally, and knowing which fruits are high in carbs and which are more keto-friendly will help you determine what fruits you can eat on keto. Most fruits taste sweet because they contain sugar. The more sugar they have, the sweeter they taste, and, sadly, the more carbs they have. However, some fruits have fewer carbs than others.
When you are on the keto diet, your goal is to reduce your carb intake and increase your healthy fat and protein consumption so that you can get your body into a state of ketosis. When your body is in ketosis, it uses the ketones from stored fats for energy rather than glucose that comes from carbs. The only way to achieve this is to limit your carb intake to less than 50 grams per day, and under 30 if you are just getting started. Fortunately, different fruits have different amounts of carbs, and you can find some that will work with your keto diet.

Fruit Has Changed Over Time

Many years ago, fruit grew in the wild, and people would pick it and eat it. Fruit is sweet, and it tastes good. In addition, it has healthy vitamins, minerals, antioxidants, and phytonutrients. As human beings began to settle down and farm, people began to farm fruit-bearing plants. People could select the qualities they liked best, and one of those qualities was sweetness.
The fruit that is grown today is bigger and sweeter than what used to grow in the wild, and it doesn’t contain the same nutritional value. Farming today focuses on faster growth rates and higher sugar content because the primary objective is increased sales and profits. As a result, this fruit has more carbs and less nutritional value.

Sugar Is in Fruit

Fruits contain naturally occurring sugar. There are three types of sugar: sucrose, fructose, and glucose. Fruits typically contain sucrose, which is a combination of fructose and glucose. These two sugars are simple sugars because each has only one sugar molecule.
Glucose is used to create energy for your body, but fructose has to be converted to glucose in your liver before it can be used. When you consume high levels of fructose, it is harder for your liver to convert it, and it can lead to cholesterol problems, fat storage in your liver, production of triglycerides, and free radical stress.
In addition, sugar has addictive properties for people and animals. Today, fruit is available all year long, and people use sugar on a daily basis. Before the modern times of instant access to anything you want, fruit was only available seasonally, and it was only available during its season. There was less of a concern with overconsumption because it was typically only available for short periods during the year.
There is more sugar in fruit today because corporations that grow fruit have selectively bred fruit-bearing plants to be bigger and sweeter, and they grow them year-round. This means that in addition to fruits being sweeter, their availability has led to increased consumption.

Fructose on Keto

Glucose and fructose are both sugars, but glucose is metabolized and used by your body to create energy for your cells to function. Fructose is also a carb, but it goes to your liver where it needs to be converted to glucose before it can be used as energy. When you digest fructose, your body will replenish its stores of liver glycogen, which can kick you out of ketosis. As with glucose, sucrose and fructose should be avoided when you are on the keto diet.

Are Fruits Nutritious

Most fruits are nutritious, but there can be a lot of carbs in fruit. When you are on the keto diet, it is important to focus on the foods that you can eat that are nutritious and low in carbs and to avoid those that are high in carbs. Many fruits do contain antioxidants that have health benefits such as lowering your risk or heart disease. Truth be told any fruit is better for you than processed junk food, but you need to limit how much you eat.

Chinese Medicine Diet

Interestingly, Traditional Chinese Medicine also agrees that eating too many fruits will lead to an imbalance in your body. This school of thought categorizes foods by their energies, which are cold, neutral, and hot. Raw fruits are thought to have cool energy, which promotes chilliness, congestion, depletion, fatigue, and mucus.
In addition, cool foods are thought to make you feel cold, give you a poor appetite, and cause stomach pain and bloating. As a result, Chinese Traditional Medicine recommends that people reduce their intake of fruits. This philosophy approaches eating from a medicinal standpoint, and they believe you should eat for health, not just for taste.
