You can have an impact on an individual and global scale, starting with what you put on your plate and beyond. Take seaweed, for example. If you’ve ever enjoyed seaweed wrapped around your favorite fish in sushi, it’s still not well known in the West. However, algae farming could change this in the very near future. Read on to find out why kelp could be the next sustainable superfood.
Why algae are important
As far as humans are concerned, research conducted in 2020 indicates that algae may have played a role in humanity’s evolution from Homo erectus to Homo sapiens, serving as a staple food in times of famine. Evidence indicates that seaweeds were used as food and medicine in Asia, Europe, and South America at least 14,000 years ago. The Romans and Celts may have used seaweed to enrich infertile soils. However, it’s not just this rich global history that makes seaweed so interesting as a modern food crop. They provide a host of other benefits, from job creation to ecosystem restoration.
Algae could even be the future of food. This is largely due to seaweed aquaculture, also known as kelp farming.
Environmental Benefits of Seaweed Farming
Systematic kelp farming can be a viable solution to various challenges, from clean ocean water to economic stimulation. Seaweed farming requires few or no resources
Seaweed is a zero input crop and leaves the ocean healthier with each harvest.
Seaweed farming requires:
no arable land
no fresh water
Algae are what are known as “non-fed” aquaculture species, meaning that they generally do not need to be provided with additional nutrients to grow. It simply uses the nutrients present in the seawater.
Seaweed farming promotes healthy oceans
The ocean absorbs about 30% of the carbon dioxide (CO2) released into the atmosphere. This causes changes in the pH of the oceans and an increase in acidity, which negatively impacts fish, corals, and shellfish such as oysters, crabs, and sea snails, organisms that are an important part of the oceanic food chain. Fortunately, algae capture carbon and nitrogen from ocean waters, which helps reduce ocean acidification. They also provide habitat for a number of organisms that live in the oceans, thus contributing to the diversification of ocean ecosystems.
reduce the amount of carbon in the ocean
reduce the acidity of ocean waters
provide habitat for species that live in the ocean
diversify ocean ecosystems.
Plus, kelp farms aren’t just good for the ocean. It appears that kelp farms can help mitigate wave energy and reduce erosion and other effects on the shoreline.
The health benefits of seaweed
When it comes to the health benefits of seaweed, the list is quite long.
For starters, seaweed is known to be an excellent source of iodine. They also have slight nutritional variations depending on the type of algae. For example, kelp is a large brown algae found on shallow shorelines where salt water is rich in nutrients.
In 100g of raw seaweed you will find:
55 percent of the daily value (DV) for vitamin K1
45% of the Daily Value (DV) for folate
29 percent DV of magnesium
16% DV of iron
13% of the daily value of vitamin A
Pantothenic Acid 13% DV
13% DV of calcium
Note: The above DVs are for an average man.
Kelp is one of the most nutrient-dense foods on the planet.
Wakame is a seaweed that has been cultivated for centuries in Korea and Japan.
Two tablespoons, or 10 grams, of raw wakame contain:
280 percent of the DV for iodine
7 percent DV for manganese
5 percent DV for folate
4 percent DV for sodium
3% of the NA for magnesium
2% of the NA for calcium
Other types of algae include:
Nori, a red seaweed used to roll sushi and often sold in dried sheets.
Sea lettuce, a type of green nori that is often eaten raw in salads or cooked in soups.
Kombu, a type of seaweed used to make soups or pickles.
Arame, a type of soft seaweed with a firm texture, sometimes used in baking.
Dulse, a red algae used to flavor recipes and eaten as a snack.
Chlorella, a freshwater algae often used as a powdered supplement.
Agar and carrageenan, gelatinous substances used as binders and thickeners of vegetable origin.
Some research shows that algae often have bioactive compounds that provide different benefits.
These compounds include in particular
proteins with essential amino acids
polyunsaturated fatty acids
Seaweed has been found to have a number of medicinal benefits, including the following
protection against cell damage
Several compounds found in seaweed have been shown to have therapeutic potential. According to a 2021 study, certain compounds in seaweed have been shown to be able to induce cancer cell death and fight metastasis.
Does algae have any drawbacks?
Although algae is a veritable gold mine for human and planetary health, there are a few things to keep in mind.
too much iodine is not good
Seaweed is an excellent source of iodine, but how much? According to a 2021 study, eating kelp once or twice a week is probably not dangerous. However, regular consumption of iodine-rich seaweeds, such as kelp, could lead to excessive iodine consumption. Excess iodine can have a negative effect on thyroid function, especially in people with pre-existing thyroid disorders, pregnant women, and infants.
Not everything is necessarily positive in the field of algae farming. There are also potential negative effects, such as an increase in the amount of growing equipment in the water, which could lead to things like contamination from abandoned or lost equipment.

A single snack to eat regularly to reduce fatigue and promote muscle recovery
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.
Reduction of risk factors associated with type 2 diabetes.
A 2012 study by a research team at the University of Medicine and Dentistry of New Jersey, Rutgers, and published in The Journal of Nutrition, found that eating almonds regularly can reduce several risk factors associated with type 2 diabetes. The study involved two groups of adults between the ages of 25 and 75 who were at risk of type 2 diabetes. One group was required to consume a snack containing 42 g of almonds per day, while the other had You must refrain from eating any almond-based snacks. The study measured several diabetes-related biomarkers, including fasting blood sugar, insulin sensitivity, and levels of triglycerides, cholesterol, and leptin.
At the end of the 12-week study period, the researchers noted that participants in the almond group had significantly lower fasting blood sugar levels, better insulin sensitivity, and lower triglyceride levels than those in the control group. . They also found that cholesterol levels decreased significantly in both men and women who ate almonds, suggesting that regular consumption of almonds may help reduce risk factors associated with type 2 diabetes.
citrus full of flavors and nutrients
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.
- 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.
- Next, inspect the skin of the grapefruit and make sure there are no bruises or discolorations, which could be signs of mold or rot.
- 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.
- 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.
- 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?
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.
Here are fatty fish with a high concentration of PUFA.
