Scientists Say People Who Drink Coffee Every Day Live Longer

Scientists Say People Who Drink Coffee Every Day Live Longer

Science has revealed some interesting facts about coffee consumption. If you have been debating on whether that second or third cup is going to help or hinder you in the health department you may want to read on. There have been some recent studies that seem to suggest that moderate coffee consumption is beneficial.

How The Study Was Conducted

Study subjects were followed for up to 30 years in order to collect data. They were provided questionnaires every four years in which researchers were able to assess the coffee drinking.

The Findings

People who had less than 5 cups of coffee a day experienced a lower risk of death due to cardiovascular disease, neurological diseases, Type 2 diabetes, and suicide.

Interestingly enough, the benefits were seen in both caffeinated and decaffeinated coffee. This suggests that it might not be the caffeine but the actual coffee beans that are creating the benefit.

A Science-y Explanation

According to Ming Ding, M.D., the study’s first author and doctoral student at the Harvard T.H. Chan School of Public Health in Boston, Massachusetts, “Bioactive compounds in coffee reduce insulin resistance and systematic inflammation. They might be responsible for the inverse association between coffee and mortality. However, more studies are needed to investigate the biological mechanisms producing these effects.”

A Surprising Link

The study also references the fact that coffee drinkers are more likely to smoke and drink alcohol. If you take this into consideration and do the testing only on non-smokers (never-smokers to be more specific), the protective benefits in coffee are glaringly evident.

The Cold Hard Numbers

The data gathered for this research is from 3 long term studies. The first contains 74,890 women in the Nurses’ Health Study. The second group is made of 93,054 of women in Nurses’ Health Study 2. The final group contains 40,557 men and is known as Health Professionals Follow-Up Study.

Deaths during the study totaled 19,524 women and 12,432 men. There was a range of what caused their deaths.

Who Should Avoid Coffee

Though the benefits are obvious, there are some groups that should limit their drinking of coffee a little more. Pregnant women and children should be cautious about the caffeine intake that might accompany the coffee.

What Now?

Though the study did seem to create links between coffee drinking and dying from some illnesses, there will need to be more studies done before anyone can say (without a doubt) that the correlations exist. This particular study was not conducted to asses a direct cause and effect between the illnesses and coffee drinking.

Before anything like that can be proven there would be a more reliable test. For instance, this test allowed the study subjects to fill out the amounts of coffee they consumed. In future studies it may be more reliable to have the researchers confirm and measure the amounts to verify.

We should also note that previous studies have not been able to see associations between coffee drinking and death related to specific death types.

An interesting question is if different types of coffee could have different types of benefits, or if all of them have the same positive effects? This is something that will hopefully be studied in the future as well.

Summary

Coffee can be part of a healthy well-balanced diet. Studies show that there are health benefits in consuming a moderate amount of coffee each day. The moderate amount is classified as less than 5 cups a day. If you are pregnant, you should be aware of the caffeine associated with drinking coffee and adjust your intake with the guidance of your doctor.

10 Brain Vitamins for Enhanced Brain Power

10 Brain Vitamins for Enhanced Brain Power

Your brain is the house your mind lives in. The brain is the most high-powered organ we have and requires the right amount and type of fuel to work properly. When we don’t give our brain the right fuel, it slows us down, dampers our focus, makes us more unhappy and unmotivated.

If you want to maximize your brain power so as to increase your focus, think more clearly and live a happier and longer life, then pay attention because this article will give you the top nutrients you need to maximize your brain power and what foods to include in your diet in order to get them.

Here are what your brain needs and where to get them:

1. Omega-3’s

Your brain is made up of 60% fat so if you want a healthy and optimally performing brain, you need to ensure you’re giving your brain the right building blocks and fat is one of the most important. Fat has been vilified over the years as being the big villain of health, but in reality, high-quality fat is not only good for you, it’s essential for your brain power and health.

Some of the most important fat to give your brain are Omega-3’s. Omega-3’s such as DHA are the essential nutrients that form the outer layer our brain cells. In fact, not getting enough omega-3’s in your diet can affect normal brain development and cognition. It has also been shown to be implicated in premature brain aging and cognitive decline.[1]

Getting healthy sources of omega-3’s from your diet is critical for optimal brain power.

Foods Rich in Omega-3’s: Walnuts, chia seeds, sardines, salmon, flaxseed, eggs, fish oil

2. Magnesium

Magnesium is an essential mineral that is critical for brain activity and has been known to calm the brain and nervous system to the point it has been called “Nature’s Natural Valium.” Magnesium is essential for hundreds of metabolic processes within the body and brain yet it is still the second most common nutritional deficiency in the world.

Magnesium helps the brain by:

  • Providing antI-inflammatory benefits
  • Lowering stress hormones
  • Increasing neuroplasticity
  • Relaxing the nervous system
  • Helping to lift depression
  • Reducing anxiety

Foods Rich in Magnesium: Almonds, spinach, cashews, avocado, black beans

3. Vitamin B1: Thiamine

Many B vitamins are known to be beneficial for brain health and well-being but for this article, let’s focus on some of the critical B vitamins.

B1, also known as thiamine, is needed for a large number of metabolic processes in the body including the processes that manage your energy. Your brain uses tremendous amounts of energy throughout the day. Having low levels of thiamine can rob your brain of the vital energy that it needs.

Thiamine can boost your mood, energy, and alertness by providing the energy your brain cells need to work effectively and keep their strength up.

Low levels of thiamine have been associated with:

  • Nerve damage
  • Nerve inflammation
  • Fatigue
  • Loss of short-term memory
  • Confusion
  • Irritability

Having enough vitamin B1 (thiamine) is essential for optimal brain performance and health by providing your brain the energy is needs to get through the day.

Foods Rich in Vitamin B1: Seaweed, sunflower seeds, macadamia nuts, lentils, black beans

4. Vitamin B6

Vitamin B6 is critical for helping to improve your mood to make you feel happier but is also important to combat mental fatigue. B6 is a critical component of building the neurotransmitters serotonin and norepinephrine.

Serotonin is known as your happy neurotransmitter and is vitally important for improving your mood. Norepinephrine helps your brain stay focused and alert.

Symptoms of B6 deficiency include:

  • Irritability
  • Loss of focus and concentration
  • Fatigue
  • Memory trouble
  • Muscle pains

Foods Rich in Vitamin B6: Grassfed beef, pistachios, tuna, turkey breast, avocado

5. Vitamin B9

Vitamin B9 is known as folate. Folate is especially important for normal brain development. Folate is an important component in creating many neurotransmitters that the brain uses to communicate and regulate our immune system. Folate is also a natural antioxidant and studies have shown that it can help preserve brain function and memory.[2]

Low levels of folate can be detrimental to the brain. Low levels of folate have shown to lead to increased degeneration in the cerebral cortex as well as cognitive impairment and decline.[3]

Symptoms of low levels of folate include:

  • Lowered immune function
  • Chronic fatigue
  • Increased irritability or anxiety
  • Brain fog

Food Rich in Vitamin B9: Spinach, beef liver, broccoli, asparagus, romaine lettuce.

6. Vitamin B12

B12 is essential for many aspects of our health and wellbeing including building strong bones, hair, skin, nails, immune system and heart health. B12 is also extremely important for your brain and mental wellbeing.[4]

B12 is necessary for many aspects of mental performance including being able to memorize and stay focused. It also plays an important role in producing serotonin and dopamine. Dopamine is your motivation and reward neurotransmitter.

Having low levels of B12 can have some serious consequences including:[5]

  • Brain fog
  • Memory loss
  • Depression[6]
  • Anxiety
  • Confusion
  • Depression
  • Hallucinations and Schizophrenia (severe cases)

B12 is commonly found in many animal products and meats, so vegetarians and vegans should pay special attention to their B12 to make sure they are getting enough of it in their diet from plant sources or supplementation.

Food Rich in Vitamin B12: Beef liver, sardines, wild salmon, eggs, nutritional yeast

7. Vitamin C

Vitamin C is a very powerful and important antioxidant for your brain. Your brain consumes a lot of energy and oxygen in order to do its job. Antioxidants like Vitamin C protect the brain from the wear and tear of doing its job.

Vitamin C is also needed to produce important neurotransmitters such as dopamine, serotonin, and norepinephrine. These neurotransmitters are important regulators of your mood, so without Vitamin C to produce these important neurotransmitters, your mood may suffer.[7]

Food Rich in Vitamin C: BroccolI, citrus fruits, bell peppers, watermelon, spinach

8. Vitamin D

The “sunshine” vitamin is arguably one of the most important vitamins that many people miss out on. Vitamin D is usually associated with bone health and heart health but it’s been shown in research that Vitamin D may play a critical role in your brain performance. Several studies have shown that low levels of vitamin D can impair cognitive function and performance.[8]

Fewer people are getting outside in the natural sunlight leading to more cases of vitamin D deficiency than ever before. The best part about Vitamin D is that you can get it for free or extremely cheap. Just a few minutes a day of natural sunlight can make a big difference in your Vitamin D levels.

Food Rich in Vitamin D: Natural sunlight or find a Vitamin D supplement.

9. Vitamin E

Vitamin E is a powerful antioxidant. Antioxidants are critical to help our bodies fight off oxidative stress. Oxidative stress is a metabolic process that occurs in the body that wears and tears on our cells. Antioxidants fight against this wear and tear to keep our cells youthful and optimally functioning.

Vitamin E is an often overlooked vitamin for brain health. It prevents oxidative stress from damaging an important component of our brain cells, DHA. DHA forms the outer membrane of our brain cells and Vitamin E works to prevents oxidative stress from damaging our brain cells to keep our brain young, energetic and high-performing.[9]

Symptoms of Vitamin E deficiency include:

  • Cognitive impairment
  • Diarrhea
  • Muscle weakness
  • Balance issues

Food Rich in Vitamin E: Almonds, kale, Swiss chard, parsley, olives

10. Zinc

Zinc is essential for neuron growth and performance. The highest concentration of zinc is located in your brain, particularly in your hippocampus, the area of the brain involved in regulating your limbic system, the region that regulates emotions. Neurons require zinc in order to communicate effectively to one another.[10]

Low levels of zinc are associated with:

  • Attention and focus problems
  • Lowered immune system
  • Acne or rashes
  • Diarrhea

Food Rich in Zinc: Pumpkin seeds, grass-fed beef, cashews, mushrooms, spinach

Keep Your Brain Sharp With Brain Foods

Your brain works hard and it takes plenty of nutrients and fuel to keep it working well. Getting the amount and type of vitamins, minerals and nutrients can make the difference in feeling energized or feeling sluggish throughout the day.

How would you fuel a Ferrari? You wouldn’t put the cheap gas in a Ferrari. It’s a high-performance machine, so you need to put in high-octane fuel to ensure optimal performance.

Eat a wide variety of foods that include a vast array of the top brain nutrients to ensure your brain is getting plenty of the resources it needs to work efficiently. If you want more brain power, make sure you give it brain power foods.
