Is bread bad for cholesterol?

Published

Presse Santé

Bread generally does not contain cholesterol, but varieties that contain animal products, such as milk and butter, do. White bread and other types of bread made with refined grains can raise a person’s cholesterol level.

Bread is a staple food for many different cultures, and there are hundreds of different types. Some varieties of bread contain dietary cholesterol, while others can raise LDL or “bad” cholesterol in the blood. However, studies suggest that dietary cholesterol has little effect on blood cholesterol levels. This article goes into more detail about bread and cholesterol, the role of whole grains in cholesterol control, and how to eat a healthy diet to reduce the risk of heart disease.

Does bread contain cholesterol?

The cholesterol content of bread depends on certain factors. There are two types of cholesterol: one in the blood and one in food, called dietary cholesterol. Most breads are made with flour, water, and yeast and do not contain cholesterol. But some types of bread are made from animal products that are high in saturated fat, which often contain cholesterol. Also, bread made with white or refined grains can raise LDL cholesterol levels. We examine this point in more detail below.

Saturated and trans fats

Some varieties of bread contain animal products such as milk, butter, or eggs, which contain saturated fat. Foods high in saturated fat are generally high in cholesterol. However, dietary cholesterol has little effect on a person’s blood cholesterol. Saturated and trans fats in food have a greater effect on raising a person’s cholesterol level.

The following table shows the approximate cholesterol and saturated fat content of different types of bread.

Type of bread Saturated fat Cholesterol
brioche (77 g piece) 11 g 134 mg
biscuits (101g) 4.36g 3.03mg
roll (60g) 1.85g 39.6mg

White bread

White bread contains refined bread flour, a process that removes the bran and germ to give the flour a finer texture.
However, this process also removes essential nutrients such as:

the iron
B vitamins
Dietary fiber

Therefore, some manufacturers add vitamins “enriching” refined flour, but do not replace fiber. This lack of fiber means white bread is less likely to make you feel full and more likely to trigger overeating. Refined grains, also called refined carbohydrates, are also digested faster by the body, which can raise blood sugar levels. A person with high blood sugar is more likely to have higher LDL cholesterol and lower HDL, or well, cholesterol.

Whole grains and cholesterol control

Whole wheat bread contains all the nutrients and fiber of cereals, making it a good source of dietary fiber. Fiber prevents the body from absorbing certain fats and cholesterol. This can lower triglycerides, another type of blood fat, and cholesterol levels and reduce the risk of heart disease. A 2019 study also found that replacing white bread, which has a high glycemic index (GI), with whole wheat bread, which has a low GI, for breakfast slows down the body’s glycemic response. Research links high blood sugar to high LDL cholesterol.

Types of wholemeal bread include those made with the following products:

integral
whole barley
Integral rice
whole oats
oatmeal
sprouted grains
whole rye
multiple whole grains

A heart healthy diet

A high level of LDL cholesterol in the blood contributes to the buildup of fats that narrow the arteries, called atherosclerosis. This increases the risk of:

heart attack
race
Peripheral arterial disease

Try eating whole grains as part of a balanced diet to lower cholesterol levels, as well as:

fruits
vegetables
poultry
fish
the nuts
non-tropical vegetable oils

Limit your intake of the following foods:

foods that contain saturated and trans fats
red and processed meats
dairy products made with whole milk
fried food
Salt
foods and drinks with added sugar
refined carbohydrates, such as white bread, pasta, and rice.

Frequent questions

Here are some answers to common questions about bread and cholesterol.

Does rye bread contain cholesterol?

Rye bread does not contain dietary cholesterol because it does not contain butter or other animal products.

Does gluten-free bread contain cholesterol?

Gluten-free bread made with animal products, such as milk, butter, or eggs, may contain cholesterol.

Summary

Bread is a staple in the diet of many people around the world. While most types of bread do not contain dietary cholesterol, some may contain animal products that are high in saturated fat. Foods high in saturated fat are generally high in dietary cholesterol. However, studies have shown that dietary cholesterol has little effect on blood cholesterol levels. Saturated fats are more likely to raise LDL cholesterol levels in our blood, as are refined carbohydrates like white bread. People should try to increase their fiber intake, including eating more whole grain breads, which can help lower cholesterol levels. This can reduce the risk of stroke and heart attack.

Presse Santé

Whether you’re an athlete looking for a competitive edge or someone who struggles to maintain their energy throughout the day, a superfood can help you reach your goals. According to a US study, eating it regularly can reduce fatigue by providing essential nutrients and helping boost physical activity. And the best? You can take it with you to the gym or the office without any problems. Do you want to know more? Keep reading!

The study in detail.

A recent American study conducted by the University of California, Davis, found that consuming 57 g of almonds per day can significantly improve a person’s ability to recover from physical activity. This randomized trial aimed to test the hypothesis that eating a daily serving of almonds might be beneficial in reducing inflammation and improving physical performance.

To do this, the volunteers were divided into two groups. One group consumed 57 g of almonds per day (divided into two equal servings, one in the morning and one in the afternoon) over a four-week period. While the second group ate a cereal bar of the same caloric value divided equally into two parts.

The researchers found that participants who consumed almond products experienced a significant reduction in markers associated with systemic inflammation compared to those who ate cereal bars with a similar caloric value.

Additionally, they observed improvements in exercise performance outcomes in those who consumed almonds daily; several participants even reported feeling less muscle soreness after exercising than before starting the four-week program.

The research team concluded that these data suggest that eating almonds may lead to better anti-inflammatory responses and increased physical performance capacity when combined with regular exercise. Making it an ideal dietary component for people looking to support their active lifestyle goals.

The benefits of incorporating almonds into your diet.

This study is very significant because it illustrates how this small change in diet can have a profoundly positive effect on overall health and well-being. In addition to being a valuable source of protein, almonds are also packed with essential vitamins and minerals like magnesium, potassium, and B vitamins, which help to better regulate energy levels and aid in muscle recovery. These nutrients will not only help athletes recover after strenuous exercise, but also those who engage in regular recreational activities such as walking, bicycling, or swimming.

In addition to providing nutritional benefits, almonds are also believed to reduce inflammation throughout the body, helping those with chronic inflammatory conditions like arthritis. Studies have also shown that people who consume a considerable amount of almonds see their cholesterol levels drop, which improves their cardiovascular health. In addition, due to its high fiber content, regular consumption of almonds can further improve digestive function, which is enhanced by the presence of healthy fats and proteins that facilitate their digestion by our body.

Dividing the 57 g of almonds into two snacks during the day reduces fatigue.

The study investigators noted that distributing the 57 g amount in small doses throughout the day helps maximize nutritional benefits. By allowing people to get the energy they need without consuming excess calories or fat.

This means that snacking on small portions of almonds split between 29g in the morning and 28g in the evening can not only provide long-lasting energy, but also prevent cravings between meals. Which makes it an extremely beneficial snack option for those looking for an energy boost without compromising nutrition.

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.

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.

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.
