Legend or not? Do oysters increase desire?



Presse Santé

Oysters are a type of shellfish that many consider a delicacy. Others may also consider them an aphrodisiac, that is, a food that stimulates sexual arousal. Although scientists haven’t proven their effects on libido, oysters do contain several compounds that may enhance sexual desire or performance.

Oysters are bivalve shellfish that are highly nutritious and may provide some health benefits. There is a long history of people associating oysters with craving. The 18th-century Italian author Giacomo Casanova is said to have eaten large quantities of oysters in particular due to their stimulating properties.

However, there is still some controversy as to whether oysters are an aphrodisiac. Although they may contain nutrients, such as zinc, that play a role in sexual function, consumption of oysters is unlikely to specifically influence a person’s libido. A person can achieve a similar effect by following a healthy, varied, and nutrient-rich diet, which may include oysters. In this article, we’ll look at what aphrodisiacs are, if oysters are, and their potential impact on libido and sexual performance.

What are aphrodisiacs and how do people use them?

An aphrodisiac generally refers to a food or drug that arouses sexual desire. The term comes from the Latin name aphrodisiaca, which was used by 17th-century physicians to describe a new class of pharmacological substances. According to a 2020 study, aphrodisiacs have been widely discredited by the medical profession since the late 1800s. However, by exchanging information about aphrodisiacs between the 16th and 19th centuries, people all over the world improved their medical understanding of sex.

An earlier review classifies aphrodisiacs into three types based on their mode of action:

  • those that increase libido, potency or sexual pleasure.

The review explains that aphrodisiacs can act through several mechanisms:

  • increasing nitrous oxide to stimulate blood flow to the penis
  • increased hormones such as testosterone
  • stimulation of the nerves involved in sexual pleasure.

Aphrodisiacs can be taken in the form of tablets, food, or plant extracts. If people consume excessive amounts of aphrodisiac foods or purchase herbal products or medications that claim to be aphrodisiacs, there may be a risk to their health.

Nutritional value of oysters

100 grams (g) of raw oysters contain:

calories: 81 kilocalories
protein: 9.45g
lipids: 2.30 g
carbohydrates: 4.95g
zinc: 16.6 milligrams (mg)
copper: 1.58 mg or 176% of a person’s Daily Value (DV)
vitamin B12: 16 micrograms (667% of the DV)
iron: 5.11 mg (28% DV)
magnesium: 22mg (5% DV)
potassium: 168 mg (4% of DV)
selenium: 77 mcg (140% DV)
health benefits

Oysters are nutritious and contain many vitamins and minerals that can benefit your health. Here are some examples:

Protein – Oysters are a great source of protein and are relatively low in calories, which means they can help people feel fuller. Research suggests that high-protein diets may help reduce obesity. Protein is present in every cell, and an adequate supply is vital to maintaining healthy muscles, bones, and tissues.

Zinc – Supports various bodily functions including immunity, wound healing, growth and development. This substance also plays a role in sexual function, which could explain why many people consider oysters to be an aphrodisiac.

Vitamin B12: A B vitamin that is important for healthy nerve tissue, brain function, and red blood cell production. When levels of this vitamin are low, people can experience nerve damage and fatigue.

Omega-3 fatty acids: Evidence indicates that these fatty acids may play a role in heart health, brain function, growth and development. They also have anti-inflammatory properties and can help reduce the risk of heart disease.

Iron: This mineral is vital for the proper functioning of hemoglobin in the blood. It is also an important safe source for growth, neurological development, and the production of certain hormones. Other research suggests that low iron levels may contribute to sexual dissatisfaction, again indicating a possible sexual benefit.

Magnesium – This mineral has many functions in the body, including muscle and nerve function, blood pressure regulation, and immune system support.

Potassium: An essential macromineral that supports key processes in the body, such as kidney, heart, muscle, and nervous system function.

Selenium: An essential trace mineral that plays a key role in thyroid function and metabolism. It also contains antioxidant properties, which may help protect against cancer, heart disease, and cognitive decline.

Do oysters increase libido?

Oysters are saltwater mollusks that people eat as shellfish. They contain or promote the production of nutrients and compounds that can improve sexual performance, desire or arousal. Can be:


One reason people may associate oysters with sexual performance is because of their zinc content. A single oyster contains 5.5 milligrams (mg) of zinc, which is half the recommended daily amount for adult men and more than half for adult women. Some research indicates that zinc is essential for maintaining sexual health and testosterone levels. In addition, it can have a positive effect on fertility. While many people associate testosterone with male libido, some evidence also suggests that small amounts of testosterone can positively influence female libido.

D-aspartic acid

Oysters also contain D-aspartic acid, an amino acid that may play a role in increasing testosterone production. As such, it may play a similar role to zinc in stimulating sexual arousal.


Zinc may also help maintain levels of dopamine, a neurotransmitter that studies have shown is involved in sexual behavior. Dopamine is responsible for feelings of pleasure and reward. According to research, it can improve erectile dysfunction in men and sexual response in women. However, no study directly measures the effect of zinc, D-aspartic acid, or dopamine from oysters on libido. Therefore, its aphrodisiac effects are inconclusive.

Omega-3 fatty acids

Shellfish, such as oysters, are a good source of omega-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Some research suggests that omega-3s may help improve sexual performance. Scientists have studied the effects of omega-3s on the heart and cardiovascular system. For example, a 2020 review concluded that there is some evidence that these beneficial fats may help prevent heart disease.

He also adds that omega-3s are anti-inflammatory and improve the function of the vascular endothelium, which controls blood flow through blood vessels. As such, they could theoretically improve blood flow to the genitals. Using a rat model of erectile dysfunction, a 2016 study found that omega-3 fatty acids decreased oxidative stress, thereby reducing damage to muscle cells and blood vessels in the penis, which restrict blood flow.

Although studies don’t show that the omega-3 fatty acids in oysters directly increase libido, they may improve sexual performance, which could have an aphrodisiac effect in some people.

Other possible aphrodisiacs

An earlier study suggests that herbal aphrodisiacs could be an alternative to pharmacological medications for some people. Although more research is still needed, some research supports the following herbal compounds as potential aphrodisiacs:

  • ginkgo
  • ginseng
  • bruise
  • tribule


Aphrodisiacs are generally foods that stimulate sexual arousal. Although many people consider oysters to be an aphrodisiac, few studies confirm this. However, oysters do contain nutrients, such as zinc, that can help improve sexual performance. Although more research is needed to determine if oysters can increase libido, they are a good source of nutrition and possibly health benefits that people can include in their diets.

2 minutes is enough to increase your longevity



Presse Santé

Don’t have enough time to exercise during the week? Or are you unable to find the motivation to do it? A new study shows that 15 minutes of vigorous exercise per week or just two minutes of vigorous exercise per day is enough. This is good news for those who do not have free time for physical activity.

Reduced risk of premature death.

This study appeared in the European Heart Journal. It shows that fifteen minutes per week or two minutes of intensive exercise per day reduces the risk of premature death by 18%.

The new study comes to support the impact of physical activity on our life expectancy.

For the study, the researchers attached activity trackers to the wrists of 71,893 adults with an average age of 62.5 for nearly seven years. Five years later, the researchers identified those who died in the meantime. People who were not physically active had a 4% risk of death during this period. In contrast, people who practiced ten minutes of exercise a week saw this risk cut in half. In total, fifteen minutes of intense physical exercise a week has been shown to reduce the risk of death by 18%.

The more you move, the better!

Of course, the more exercise you do, the better. According to the recommendations of the World Health Organization, a “healthy person” performs an average of 150 to 300 minutes of moderate physical exercise per week. You can also opt for 75 to 150 minutes of vigorous exercise per week. Research shows that these guidelines reduce the risk of premature death by 21%. Do you exercise more than the number of minutes listed above? In this case, the benefits in terms of useful life are even greater.

The benefits of sport for your brain.

More mental resilience.

When exercise is done at high intensity, the body develops physically, but also mentally, as it “adapts” to new challenges and learns to handle more load and stress. On training days, overall mental performance is better than on rest days. Memory seems to improve, as well as coordination and reaction speed.

Better mood.

Through the production and exchange of dopamine, oxytocin, serotonin, endorphins, adrenaline, etc. in the brain and in the body, the organism is rewarded with a feeling of well-being during and after exercise.

Stress management.

When your brain releases chemicals, your body “receives” stimuli to relieve pain, reduce stress and inflammation, body aches, insomnia, fatigue, and anxiety. In addition, thanks to better mental resistance, athletes can better manage stressful situations. Sport is a way to release “bad stress” and balance the body for the mental and physical challenges ahead.

improved health.

Sport strengthens the functions of the cardiovascular system, the respiratory tract and the nervous system. Sport is a key factor in “refining” your metabolism. All of this should lead to better overall health.

power charge.

In many medical and sports articles it is said that after a few minutes of sports an effect called “runner’s high” is achieved and that it is due to the chemicals that are produced “to manage” the effort. This “energy charge” includes chemicals for load resistance, stamina, pain relief, etc. The end result is a feeling of “energy” (as long as the training does not continue until exhausted by fatigue). In many articles it is mentioned that even 20 minutes of activity can already help you “get” a high energy charge.

6 questions you should ask yourself for a 100% effective diet



Presse Santé

Your weight loss success largely depends on your willingness to rise to the challenge. If you take the plunge before you’re ready, your weight loss program could fail at the first hurdle.

Knowing that you need to make changes in your life and actually making them are two different things.

Use these questions to assess your readiness to lose weight.

Are you motivated to make long-term changes to your lifestyle?

Successful weight loss depends on making permanent lifestyle changes, such as eating healthy, low-calorie foods and including physical activity in your daily routine. This could represent a significant departure from your current lifestyle.

You may need to revise your diet to eat more whole grains, fruits, and vegetables, for example. It will be important to eat a variety of healthy foods. You’ll also need to find time for physical activity, ideally for at least 30 to 45 minutes, or more, most days of the week.

Find your motivation and focus on it:

Your true motivation is the best guarantee of success, but what is it? To make these changes, ask yourself first why you want to lose weight, all these changes to:

  • have better health,
  • better appearance
  • feel better about yourself
  • better way
  • start a new love story

Have you identified anything in your life that might distract you from your weight loss goal?

If you’re dealing with major life events, such as marital problems, work stress, illness, or financial worries, you may not want to add the challenge of reviewing your eating habits and time spent being physically active. It may be better to wait until the right time to embark on your weight loss program to limit the risk of failure due to external factors that are too heavy.

Do you have a realistic picture of how much weight you will lose and how fast?

Reaching and maintaining a healthy weight is a lifelong process. Start by making sure your weight loss goal is safe and realistic, such as losing 5 percent of your current weight.

Try to start losing 0.5 to 1 kilogram per week until you reach your goal. This means burning 500 to 1,000 more calories than you consume each day, through diet and exercise.

You could lose weight faster if you change your habits significantly. However, be careful. Radical changes that are not sustainable are unlikely to be effective in the long term.

Have you resolved emotional problems related to your weight?

Emotions and food are often intertwined. Anger, stress, grief, and boredom can trigger emotional eating. If you have a history of disordered eating, losing weight can be even more difficult.

To prepare for challenges, identify emotional issues related to eating.

Do you have support around you?

Any weight loss program can be difficult. You may face moments of temptation or discouragement. Having someone around you to offer encouragement can help. If you don’t have friends or loved ones you can rely on for positive help, consider joining a weight loss support group.

If you want to keep your weight loss efforts to yourself and not tell anyone about it, it will be more difficult. But maybe you’re ready to be responsible to yourself: set up dates with yourself then. With summary about:

  • – regular weigh-ins
  • – monitor your diet
  • – track your physical activity

Have you really accepted the weight loss challenge?

If you don’t have a positive attitude toward weight loss, you may not be ready. And if you fear what’s to come, you’re more likely to find excuses to veer off course.

Instead, try to take a nice view of your new lifestyle and stay positive. Focus on how good you will feel when you are more active or weigh less. Imagine celebrating all the successes along the way, whether it’s enjoying a new food, completing another workout, or losing your first few pounds.

If you answered yes to most or all of the questions

You are probably ready to make lifestyle changes that will help you lose weight permanently. Get ahead with healthy eating and regular physical activity, starting today!

If you think you need help, see a dietitian or join a reputable weight loss program. If you have a significant amount of weight to lose, you may benefit from follow-up with a therapist or obesity specialist.

If you answer no to more than one of the questions

You may not be ready to embark on a weight loss program right now, and that’s okay. Explore what’s holding you back and face those obstacles.

Consider seeking help from a professional weight loss tracker to help you deal with any roadblocks. Then, reassess your readiness for your weight loss program so you can get off to a great start.

Ready, set, let’s go

If you can’t answer every question with a simple yes or no, but overall you feel positive and confident with your answers, consider starting now.
