Flavonols are a class of antioxidant compounds found in tea, red wine, broccoli, beans, tomatoes, and leeks that have anti-inflammatory properties.
The data, mostly from animal studies, suggest that higher intakes of flavonols may protect against Alzheimer’s disease and dementia.

A recent longitudinal study found that higher dietary intake of flavonols was associated with a slowing of age-related decline in general and specific areas of cognitive function.
A recent study published in Neurology shows that a higher intake of flavonols, a category of flavonoids found in fruits, vegetables, tea, and wine, was associated with slower cognitive decline in older adults. The study adds to limited but growing data showing an association between dietary flavonol intake and brain health.

A healthy diet containing a variety of fruits and vegetables is essential for good health, especially brain health. In general, it is known that the vitamins and minerals present in these foods are important. But we now understand that it is the entire composition of the food, including bioactives like flavonols, that makes these foods beneficial.

Flavonoids and brain health

Flavonoids are a class of compounds produced by plants that possess antioxidant and anti-inflammatory properties. Flavonoids are found in commonly eaten fruits and vegetables, including berries, cherries, leafy greens, tomatoes, onions, apples, citrus fruits, and beans. Beverages such as tea and red wine are also important sources of dietary flavonoids.

Previous studies have shown that higher dietary intake of flavonoids is associated with slower cognitive decline that normally occurs with aging and also due to Alzheimer’s disease. These effects of flavonoids have been attributed to their ability to reduce oxidative stress, decrease inflammation in the brain, and increase brain plasticity.

There are six main subclasses of flavonoids, namely flavonols, flavan-3-ols, flavanones, flavones, isoflavones, and anthocyanins. Additionally, several compounds make up each subclass of flavonoids. For example, flavonols include compounds such as quercetin, kaempferol, isorhamnetin, and myricetin. Although animal studies suggest a beneficial impact of certain flavonols and their individual components on cognition, similar data from human studies is limited.

Does the intake of flavonols affect cognitive function?

The present study includes data from 961 participants who reside in Chicago retirement communities and public housing for the elderly and are enrolled in the Rush Memory and Aging Project. The Rush Memory and Aging Project is a longitudinal study whose objective is to identify the factors associated with the deterioration of cognitive and motor functions caused by aging and Alzheimer’s disease. Participants were between the ages of 58 and 100 and had not been diagnosed with dementia at the time of enrollment. The researchers annually assessed the participants’ cognitive function and risk factors associated with cognitive decline.

To assess cognitive function, a trained technician administered a battery of 19 tests spanning five different cognitive domains. These five areas were:

episodic memory: a form of long-term memory that encompasses memories of events and experiences
semantic memory: a form of long-term memory that encompasses factual and conceptual knowledge
working memory: a form of short-term memory that temporarily stores and manipulates information
perceptual speed: the ability to quickly process visual information
Visuospatial Ability: Ability to perceive spatial relationships and manipulate images mentally.

Based on overall performance on the 19 cognitive tests, the researchers quantified each participant’s overall cognitive function.

To assess dietary intake of flavonols and individual flavonol components, the researchers used a standardized questionnaire to estimate the frequency of consumption of flavonol-containing foods in the past year. The researchers then examined the association between dietary flavonol intake and cognitive function after adjusting for factors associated with cognitive decline, including age, gender, education level, smoking status, physical activity level, and participation in activities that enhance cognition. The analyzes suggested that a higher intake of flavonols was associated with a slower decline in general cognitive function.

In this study population, people who ate the most flavonols (an average of 7 servings of dark green leafy vegetables per week) compared to people who ate the least had a 32% decrease in their rate of deterioration cognitive.

2 Antioxidants Linked to Slower Decrease

Furthermore, higher consumption of flavonols (kaempferol and quercetin), but not isorhamnetin or myricetin, was associated with a slower decline in general cognitive function. Looking at changes in specific cognitive domains, the researchers found that higher flavonol intake was associated with slower declines in episodic memory, semantic memory, perceptual speed, and working memory, but not visuospatial ability.

Among individual flavonol components, higher kaempferol intake was associated with a slower rate of decline in all five cognitive domains. By contrast, myricetin was not associated with a change in cognitive abilities, but was suggestive for working memory. Quercetin consumption was associated with a more gradual decline in episodic and semantic memory, whereas isorhamnetin consumption was correlated with a more gradual decline in episodic and suggestive memory for visuospatial memory.

Leafy vegetables are the richest source of kaempferol. Tea, onions, leeks, broccoli, beans, tomatoes, and berries are some of the other main sources of other flavanols.

In addition to having beneficial effects on brain health, another recent study reported an association between increased intake of flavonoids, including flavonols, and a marker of subclinical atherosclerosis. This further highlights the potential protective effects of flavonoids on not only brain health but also cardiovascular health.

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.

10 valuable tips from a naturopath for the good of your thyroid

Published

on

Presse Santé

The thyroid gland is one of the most important, but also the most misunderstood, organs in our body. It helps regulate hormone production and metabolism, making it vital for optimal health! Unfortunately, with the increase in environmental toxins and stressors that we all face on a daily basis, many people suffer from hypothyroidism or hypothyroidism.

If you are looking to support your thyroid health naturally, either as prevention or as part of a healing process, then this article is for you! We are going to cover 10 practical naturopathic tips to incorporate into your mealtime diet that can help your thyroid function better and contribute to better overall health. He went !

  1. Prioritize clean proteins.

Incorporate clean proteins, such as wild-caught fish and pasture-raised eggs, into your diet. Try to eat these foods at least several times a week. These types of proteins are packed with nutrients that help regulate thyroid hormones, while also providing essential fatty acids that support overall health.

  1. Stock up on green leafy vegetables.

Be sure to include plenty of leafy greens like kale, spinach, Swiss chard, and broccoli in your meals. These vegetables are high in iodine, which helps the thyroid to produce hormones more efficiently. They are also loaded with vitamins and minerals that contribute to better overall health.

  1. Do not miss the products rich in probiotics.

Increase your intake of probiotic-rich foods, such as yogurt, kefir, sauerkraut, kimchi, or miso, all of which contain beneficial bacteria that promote healthy digestion and efficient absorption of nutrients from food. Probiotics have been found to have positive effects on the functioning of the thyroid gland, as well as the rest of the body’s endocrine system.

  1. Eliminate processed foods from your table.

Cut down on processed foods that contain refined sugars as much as possible and replace them with healthier options, including fresh fruits and vegetables, legumes, and nuts/seeds. Refined sugars can cause insulin levels to rise, which can affect how your thyroid gland works and lead to hormonal imbalance over time.

  1. Boost your body’s natural response with omega-3s.

Incorporate omega-3-rich foods into your diet, such as wild salmon, mackerel, sardines, and anchovies, all of which are excellent sources of healthy fats that help support the body’s natural inflammatory response and reduce inflammation throughout the body (including in the thyroid). ).

  1. Leave room for crucifers.

Eat plenty of cruciferous vegetables such as cauliflower, Brussels sprouts, and cabbage – these vegetables aid in good detoxification to remove excess hormones from our bodies more efficiently without overtaxing the liver or kidneys; This is especially important for people with an underactive thyroid who may have a buildup of hormones in their system due to poor removal process from other organs/glands affected by this disorder!

  1. Choose organic ingredients whenever possible.

It is essential to consume organic products (whether plant or animal based) to maintain optimal health. Since toxins found in non-organic crops can interfere with our body’s natural hormonal balance when ingested long term due to their buildup in our system. They can also decrease the absorption of nutrients from food sources!

  1. Consider iodine supplementation.

Consider supplementing your diet with iodine if recommended by your naturopath. Iodine contributes to the healthy production and metabolism of the hormones thyroxine (T4) and triiodothyronine (T3), both necessary for normal function and communication between cells! It is important not to self-medicate; Always talk to a professional first for best results and for your safety!

  1. Consider adaptogenic herbs.

Be sure to incorporate adaptogenic herbs regularly throughout the day. These herbs help nourish and restore balance between our endocrine system and adrenal glands, while supporting overall well-being during times of stress or fatigue. For example, Rhodiola Rosea root extract or Ashwagandha root powder, but make sure they are only quality products!

  1. Finally, don’t forget the selenium.

It plays an important role in regulating thyroid hormone production, so be sure to include Brazil nuts or shellfish on a regular basis if you want maximum benefits. Selenium also helps protect against oxidative damage caused by free radicals, which has been linked to certain autoimmune disorders that also affect thyroid function. So treat yourself and take advantage of its many advantages!
