The 7 secrets of the Okinawan diet

Published

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.

Grapefruit is an exotic citrus fruit that resembles a thicker, rougher-skinned grapefruit. It comes directly from Florida, where it is eaten raw or cooked to enhance the flavor of dishes. But its uses don’t end there – researchers have identified the potential benefits of this power-packed superfood! In this article, we’ll dive into the world of grapefruit to better understand its health benefits and how to choose it at the store. Get ready to savor the delights of this unique fruit while enjoying its long-lasting benefits!

Grapefruit and pomelo: two different citrus fruits.

Grapefruit and grapefruit may look alike, but they differ in some important ways. The grapefruit is larger than the grapefruit, usually measuring between 15 and 20 cm in circumference. Its skin is softer and its flavor more pronounced. Grapefruit tends to contain more seeds than grapefruit. As for the grapefruit, its skin is thicker and more pointed than that of the grapefruit and its pulp is sweeter and less spicy. Grapefruit contains fewer seeds than pomelo. Both fruits are highly nutritious and provide multiple health benefits when included in a balanced diet.

Grapefruit: its health benefits.

Grapefruit is a large citrus that is gaining popularity due to its health benefits. It is highly nutritious and offers a range of vitamins, minerals and antioxidants that can help improve overall health.

Provides a variety of vitamins, minerals, and antioxidants.

Grapefruit contains many essential vitamins and minerals, including:

  • Vitamin C: It is a powerful antioxidant that helps protect cells from damage caused by free radicals. In addition, it promotes skin and bone health. Potassium helps regulate blood pressure, prevents muscle cramps, and maintains healthy nerve function.
  • Magnesium: helps improve sleep quality and reduce stress levels.
  • Calcium: contributes to bone strength and muscle contraction.
  • Match: helps absorb energy from food into body cells
  • The iron : helps in the formation of red blood cells that carry oxygen throughout the body.
  • Manganese: it adds flavor to foods and is an essential trace element for enzyme function.

The antioxidants found in grapefruit are also beneficial to human health by protecting against oxidative damage that can lead to chronic diseases such as cancer or heart disease. These include flavonoids like hesperidin, naringenin, and quercetin that have anti-inflammatory properties and help boost the immune system. In addition, grapefruit contains carotenoids such as beta-carotene, which acts as a natural sunscreen for the skin and helps preserve vision.

It can help with weight control.

Eating grapefruit regularly can also aid weight loss thanks to its fiber content, which is both plentiful and low in calories. Therefore, it supports digestion by helping to eliminate waste from the body more quickly than other fruits or vegetables with a similar fiber content. Additionally, studies show that compounds in grapefruit may also have anti-obesity effects on fat metabolism. While some of its organic acids (such as citric acid) can slow down the digestion of starch, thus lowering the glycemic index of foods when eaten with them.

Regulates blood sugar.

Studies have shown that eating foods high in dietary fiber can help improve blood sugar control, which helps the body control blood sugar more effectively. The insoluble fiber found in grapefruit makes it an ideal choice for those who have trouble controlling their blood sugar.

Additionally, grapefruit contains vitamins and minerals such as magnesium, calcium, and potassium, which also help regulate fluids in the body, helping to maintain healthy blood sugar levels. Eating grapefruit regularly can help people maintain healthier blood sugar levels and get the added benefits of its many vitamins and minerals.

Grapefruit: how to choose it?

To choose a grapefruit, several elements must be taken into account.

  1. First, look for a grapefruit that is even in color and feels heavy for its size. The heavier the grapefruit, the juicier it will be on the inside.
  2. Next, inspect the skin of the grapefruit and make sure there are no bruises or discolorations, which could be signs of mold or rot.
  3. Touch the rind of the grapefruit; if the bran is hollow, it means it is ripe and ready to eat. The exterior should also be slightly pliable when squeezed, indicating that it is ripe.
  4. When you smell a grapefruit, you should be looking for a grapefruit-like aroma. If it doesn’t smell much, it probably hasn’t matured properly yet. The texture of a ripe grapefruit should be slightly rough and thick, with a few wrinkles around the edges.
  5. Finally, when you cut into the fruit, you should see large sections separated by thin membranes that contain the edible segments. The color of these membranes can vary from white to pink depending on the variety, but they should all be juicy and sweet, with a few seeds here and there.

Ultimately, choosing a good grapefruit requires careful selection based on sight, smell, touch, and taste, as each element plays an important role in determining overall quality.

How much oily fish should you eat to improve your kidney health?

Published

on

Are you aware of the potential dangers to your kidneys if you don’t get enough oily fish in your diet? Most people are unaware of how vital maintaining a balance of healthy fats from different sources is to overall good health. Eating fatty fish too often may protect you from chronic kidney disease, according to an Australian study. In this article, we’ll explore everything about eating fatty fish and its effects on kidney health, including the benefits that can be gained from eating them, the types of fish that are better for you than others, as well as how much to consume per day!

This Australian study highlights the importance of eating fatty fish to maintain better kidney health.

A recent Australian study published in the British Medical Journal (BMJ) found that increasing consumption of omega-3 polyunsaturated fatty acids, found in oily fish and other shellfish, can reduce the risk of chronic kidney disease (CKD) and slow the onset of kidney damage. function. Through a pooled analysis of 19 different cohorts, the researchers were able to reach this conclusion by looking at data from participants around the world.

The research team collected data from 19 different cohorts with a total of more than 400,000 participants to assess how omega-3 polyunsaturated fatty acids (PUFAs) influence the development of chronic kidney disease. Their findings suggest that PUFA consumption is linked to a lower risk of kidney disease.

Lead author of this study, Dr. kwok leung ong, notes that “despite evidence of a protective effect of omega-3 polyunsaturated fatty acids against cardiovascular disease, little research has been done on their role on outcomes kidneys”. He believes this is an important step forward in understanding the role of our diet in the development and prevention of chronic kidney disease.

On average, if you eat two servings of oily fish a week, you are less likely to suffer from chronic kidney disease.

A study conducted jointly by the George Institute for Global Health and the University of New South Wales found that regularly eating at least two servings of fatty fish such as mackerel, sardines or tuna per week can greatly reduce the risk of develop kidney disease.

In this particular cohort study, participants were asked to complete meal frequency questionnaires, in which they were asked to report the types and amounts of food they regularly consumed. The data was then used to estimate an individual’s daily PUFA intake, allowing correlations between PUFA intake and CKD incidence rates to be inferred.

The results showed that people who ate two or more servings a week had a 15% lower risk than those who ate virtually nothing in seven days. In addition, higher levels of omega-3 polyunsaturated fatty acids from fish were also associated with a 20% lower risk of developing chronic kidney disease compared with low intakes from plant sources.

These findings could have huge implications for public health. Since this is the first time we’ve seen evidence showing the potential protective effects of PUFAs in preventing chronic diseases such as kidney disease, which can be difficult to treat once they get past the initial stages.

At this time, it is not clear exactly why these saturated fatty acids may provide such protection, but scientists are eager to continue exploring this topic in the hope that it may open up even more possibilities in terms of dietary interventions to promote a healthy diet. better long-term health. results.

10 foods that you should prohibit your cat for its well-being

Published

on

Presse Santé

When it comes to caring for cats, you need to make sure they have a nutritious and balanced diet. However, some foods can do more harm than good if they are part of your regular meals or treats. Knowing what foods not to feed cats is important to keep your pet safe and healthy. Here are the 10 foods you should never give your cat!

  1. Chocolate :

Theobromine is the toxic compound found in chocolate that cats are sensitive to. Depending on the type of chocolate and the amount eaten, your cat could experience vomiting or diarrhea, an abnormal heartbeat, seizures, or even death if he consumes enough. Keep all the chocolate out of your reach!

  1. Grapes and raisins:

While grapes and raisins are healthy treats for humans, they are very dangerous for cats, as they can cause severe kidney failure in some cases. Symptoms can include excessive consumption of water and urine, followed by abdominal pain, loss of appetite, dehydration, and ultimately death within days or weeks of eating these treats.

  1. Raw Fish :

Raw fish can contain parasites like tapeworms that not only harm your cat, but can also be passed to humans through contact with the cat’s skin or feces. Additionally, raw fish contains an enzyme called thiaminase that breaks down thiamine (B1), essential for cats’ health, making eating raw fish nutritionally hazardous as well!

  1. Onions and Garlic:

Onions and garlic belong to the Allium family and contain high levels of sulfur-based compounds, called thiosulfates, which can cause gastrointestinal irritation in cats when eaten in large amounts. Regular consumption of these foods can even lead to anemia due to the damage caused by a lack of red blood cells over time in your cat’s body!

  1. Dairy products :

Many cats experience adverse reactions when consuming dairy products, such as lactose intolerance, which leads to digestive problems such as diarrhea or vomiting, due to their inability to break down the lactose present in the milk after feeding.

  1. Caffeine:

Caffeine is very toxic to cats, as it acts as a stimulant on their nervous system, causing restlessness followed by a rapid heartbeat and breathing difficulties in some cases, if enough is consumed! It also causes acidic urine, which can lead to bladder stones if consumed regularly over a long period of time. So it’s best not to leave coffee beans within the reach of your furry friends.

  1. Raw eggs and meat:

Although some pet owners may feed their cat raw eggs or raw meat from time to time, these foods should generally be avoided as they may contain salmonella or other bacteria that could make your cat sick over time if eaten regularly enough. It’s also worth noting that raw eggs can interfere with the absorption of essential vitamins in a cat’s diet, which could ultimately lead to long-term nutritional deficiencies if eaten too frequently.

  1. raw potato:

Although raw potatoes may not seem like an unlikely cat snack, they are actually very dangerous. Cats, just like humans, can get sick from eating raw potatoes due to the calcium oxalate they contain. This substance can build up and cause kidney stones, leading to severe pain and uncomfortable visits to the vet. In short, it’s best for cats to avoid any raw potato products to keep them as safe as possible.

  1. Canned tuna:

Feeding tuna to your cats can spice up their diet and give them a lot of pleasure, but as owners it’s important to be aware of the potential dangers. Canned tuna contains too much fat and salt and not enough taurine, which can lead to vitamin E deficiency if eaten too often. Digestive problems can also arise, and cats are particularly susceptible to food addiction: when they eat a certain food, it can be difficult for them to change their diet. This is why canned tuna should always be considered a treat rather than a staple in your cat’s diet.

  1. delicatessen :

Deli meats consist of a variety of high-fat proteins that can cause gastrointestinal upset and weight gain in cats that eat them regularly. When you decide to give your cat a special food, make sure it is a safe food that will not harm her or disrupt her diet.
