Why Flaxseeds Have A Beneficial Effect On Breast Cancer Risk

By on in Cancer, Diet, Eating, General Health | 0 comments

It’s not because of reduced inflammation.

Adapting habits research has found to be beneficial for reducing cancer risk is a good idea, since your body does not give you any early warning signs.

Pain is not a good indicator for cancer.

Cancer usually takes quite a while to develop, pain occurs later.

We know that low-grade inflammation, the type of inflammation we usually are unaware of increases cancer risk, but what else than reducing inflammation can you do?

You can eat more lignans.

Lignans are plant-derived compounds with anticarcinogenic properties.

Lignans are metabolized to enterolignans, and as such, they have shown to reduce the risk of breast cancer.

Research has documented that patients with breast cancer who have higher enterolactone levels, a marker of dietary lignans, have significantly better survival (Buck K, et.al., 2011). This was for estrogen-receptor negative tumors.

21 studies showed that high lignan exposure was associated with reduced breast cancer risk in postmenopausal women (Buck K. et.al., 2010).

Where do you find high amount of these beneficial lignans?

You find this kind of lignans in flaxseeds.

When patients with breast cancer were given either a daily 25 g of flaxseed-containing muffin or a placebo, a reduction in apoptosis (death of cancer cells) was seen in the flaxseed group, but not in the placebo group (Thomson LU, et.al., 2005).

This was after only 32 days.

Higher intake of dried beans, but not grains, fruit or vegetable also reduced the overall mortality risk somewhat, and the highest lignan intake reduced the risk significantly (McCann SE, et.al., 2010).

I suggest you buy organic flaxseeds and grind 2 tablespoons in a coffee grinder for approximately 15 seconds. Put them in a little bit of water and stir. Do that once or twice daily, and drink it thick. I think they taste good when I do it that way. But, it does not matter how you do it, as long as you ingest them. You can also sprinkle it on food if you prefer that.

Just a simple habit like this may help you stay healthier.

1 Healthy Source Of Fat You Should Not Miss

By on in Blood Pressure, Diabetes, Diet, Eating, Fat, General Health, Nut consumption | 0 comments

 

Nuts are a very healthy source of fat for several reasons, and it is easy to add to your diet.

 

While all nuts provide health benefits, some offer more benefits than others.  

 

Pistachios are the best ones.

Research has documented that pistachios provide cardiovascular benefits by reducing LDL cholesterol, the so-called bad cholesterol and increase HDL cholesterol, the good cholesterol (Kasliwal RR, et.al.,2015). This was achieved with a daily consumption of 40 g of pistachios daily for 3 months, which also improved brachial artery flow-mediated vasodilation and carotid-femoral and brachial-ankle pulse wave velocity. These are measurements of the function of the inner lining of the blood vessels and arterial stiffness. In addition to all of this, the blood glucose levels also improved.healthy source of fat: pistachios

 

Even if you have diabetes, nuts can help you.  

25 g of pistachio nuts twice daily decreased fasting blood glucose, systolic blood pressure, and CRP, an inflammatory marker (Parham M, et.al., 2014). Not bad for snacking on some nuts twice a day.  

 

Another nut which is also among the best is walnuts.  

Walnuts measured the highest amounts of polyphenols when 9 types of nuts were compared (Vinson JA, Cai Y, 2012). Polyphenols are antioxidants that would inhibit oxidative processes leading to atherosclerosis.  

 

A high-fat meal has shown to decrease endothelial function, but if you add 40 g of walnuts to the meal, it will improve flow-mediated dilation (Cortes B, et.al., 2006). Walnuts will also decrease oxidized LDL cholesterol and inflammation. Oxidized LDL is the most dangerous LDL.

diabetes tacker: healthy source of fat

Do you have high cholesterol?

Even in people with high cholesterol, walnuts have shown to improve endothelial function and reduce total cholesterol and LDL cholesterol (Ros E, et.al., 2004).

 

You can even help to improve your brain function by eating walnuts. The polyphenol in walnuts has not only been found to reduce the oxidant and inflammatory exposure of brain cells but has also been found to improve interneuronal signaling (Poulose SM, et.al., 2014).

Is Saturated Fat Bad For You?

By on in Cardiovascular Disease, Cholesterol, Diet, Eating, Eating, Fat | 0 comments

 

It is important to know the facts about saturated fat, because there are different opinions on this topic.

 

If you get it wrong, there may be serious health consequences as a result.

 

I think you agree that it is important to have a healthy cardiovascular system, because the blood is supplying the tissue with nutrients. It is especially important for the heart. Any chance that the blood supply to the heart gets compromised, you will be in big trouble.

 

If somebody claims that saturated fat is healthy, and it will not increase your cholesterol, a reference with good evidence should be provided. Moreover, if the author is not providing any evidence, or is referring to an article in the popular press, the author is only presenting his or her opinion.

 

You need evidence in the form of research published in a medical journal.

 

Even if the research is published in a medical journal, it may still not be designed well and could be biased. That’s why you will always find references with a link to the original abstract in the articles I write, to make it easy for you check the facts.

 

I have not found any reliable research so far supporting that saturated fat is healthy. I have however found studies showing that saturated fat is increasing cholesterol, especially LDL cholesterol, the most harmful type. This means that saturated fat will increase your risk for cardiovascular disease.

 

In a very recent research, 92 men and women were put on a diet. The first group has a diet which consisted of high in saturated fat from either cheese or butter. Some of them are on a diet high in monounsaturated fat or polyunsaturated fat. Moreover, the remaining participants were in a low-fat diet high in carbohydrates. Each of the group had the diet for 4 weeks. This is what was found (Brassard D, et.al., 2017).  

 

LDL cholesterol increased the most after the butter diet, even more than after the cheese diet. Both the butter and the cheese diet increased the LDL more than the high carbohydrate diet. The diets are also high in monounsaturated fat and polyunsaturated fat.  

 

The following research is a summary of 12 studies. It also compared butter with cheese, and found the following. Cheese intake lowered LDL when compared to butter, but when compared to tofu, it increased LDL (de Goede J, et.al., 2015). This is the same as saying butter increased LDL more than cheese, and both butter and cheese increased LDL more than tofu.     

 

The HDL cholesterol, which has been considered protective for cardiovascular disease, was increased after the butter and cheese diets. It was significantly higher than for the carbohydrate diet. This may look like a benefit until you look at this study published in one of the most prestigious medical journals in the world the Lancet (Voight BF, et.al., 2012).

 

When people with genetically high HDL were compared with people without these genes, it did not seem to lower the risk of myocardial infarction.  

 

What would be found if people with genetically low LDL were examined? This has been done.  That particular study was published in another of the world’s most prestigious medical journals (Cohen JC, et.al., 2006).

 

It was found that people with genetically low LDL had a substantial reduction of coronary events. This is still the case even in the populations with a high prevalence of other non- cholesterol risk factors.

 

In another research, men with low cholesterol levels at the start were followed for many years. They had an estimated increased life expectancy of 3.8 to 8.7 years (Stamler J, et.al., 2000).

 

Research shows us that saturated fat from animal sources is not good, it will increase your risk for cardiovascular disease.

 

The good news is that you can control that to a large extent by changing what you eat. By doing so, you can produce the results you want.

Exposure To This May Decrease Your Testosterone

By on in Eating, General Health | 0 comments

As we get older testosterone will decrease somewhat. That’s normal and does not represent a problem, but we don’t want it to be too low.

There are certain things that have shown to affect testosterone levels. This research investigated the relationship between polychlorinated biphenyls (PCBs) and testosterone levels (Goncharov A, et.al., 2009).

It was found that testosterone concentration in men was inversely correlated with total PCB concentration. In other words elevation of PCB in the blood is associated with lower testosterone levels.                                                                                                  

How do we get exposed to PCB and other chemical toxins?

Fish and especially farmed fish are known to be contaminated (Shaw SD, et.al., 2008). It is better to avoid farmed fish since farmed fish usually is contaminated by several things. If you like to eat salmon keep in mind that Atlantic salmon which is what you usually get at restaurants and in stores is farmed salmon. It is difficult to completely avoid contamination now, but if you are going to eat fish, wild salmon is better.

If you are eating fish for the beneficial omega 3 fat, a high-quality fish oil is even a better choice, since most of the contaminants should have been removed in the manufacturing process.

This Causes Low Testosterone: Important For Men and Women

By on in Eating, General Health | 1 comment

Testosterone not only affects sexual function but also affects how we feel emotionally and physically.

Women also need testosterone even if they need less than men.

Testosterone levels may also have an effect on how long we live.

 

Research has shown that optimal blood levels of testosterone in older men is associated with reduced mortality (Yeap BB, et.al., 2014).

The use of testosterone was however not affecting the build up of deposits in the arteries of older men with low to normal testosterone (Basaria S, et.al., 2015).

According to these 2 studies, it would be beneficial if you can maintain optimal testosterone levels without using a testosterone replacement.

Low sexual desire in women has been associated with low blood levels of free testosterone, that’s the testosterone the body can use (Wahlin-Jacobsen S, et.al., 2017).

How we act may also be affected by our testosterone levels.

Salivary testosterone, that the free testosterone the body can use, has been associated with extraversion (Smeets-Janssen MM, et.al., 2015).

The food we eat can actually have quite an effect on our testosterone levels. You can either increase it or decrease it, depending on what you eat.

Most people are probably not aware of that, but the research has been available for many years, and it is very interesting. It is most likely not what you expected.

When seven normal men were eating a high carbohydrate diet for 10 days, their testosterone concentration was consistently higher than after ten days on a high protein diet (Anderson KE, et.al., 1987).

It is also interesting that the stress hormone cortisol was consistently lower during the high carbohydrate diet than it was during the high protein diet.

It is important to get enough protein, but we don’t need that much. Less than 1 g per kg of body weight is enough for most people unless you exercise very hard and a lot, then your needs will increase a little bit, but not that much.

Can Certain Food Cause Stress?

By on in Eating, Stress | 0 comments

Some people eat when they get stressed and nervous to calm themselves down, but can certain food cause stress?

That’s what this research investigated (Gibson EL, et.al., 1999).
Cortisol was measured in the saliva which means it was free cortisol, that’s the part of the hormone that will have an effect, since some are protein bound, and is not free to act on the tissue.

The cortisol was measured before and after a high protein (35% of total calories) meal and after a low protein(5% of total calories) meal in healthy participants.

The results showed a significant increase in cortisol after the high protein meal, but not after the low protein meal.

The increase in cortisol also correlated with poor psychological well-being.

Think of food as cell signaling compounds, they do a lot more than only provide energy.

A plant-based, vegan diet is low in protein, and this is one more reason why it makes good sense.

There has never been documented any benefits by eating more protein than we need, and research shows that we don’t need that much.
