Fertility Diet - How Carbohydrate Affects Fertility and Infertility

Healthy Diet is always important for all people in any age and even more important for a couple trying to conceive. Most of the couple can be conceive naturally without changing their diet at all, but for some couples it may require some determination and affords, especially if you have try to conceive after a few months without success. Nutrients deficiency or intake of wrong kinds of nutrient may be the causes, because bearing a baby requires a lots of nutrients and co operation of the all the reproductive organs as well as your brain and glands. Is carbohydrate good or bad for fertility? In this article, we will discuss how carbohydrate effects fertility

I. Definition
Carbohydrate is also known as sugar, it plays an important roles by providing us with the largest percentage of energy between 40 to 55% of total calories. It contains glucose, galactose, and
fructose and can be classified into 2 types.

II. Types of carbohydrate
A. Simple sugar
1. Glucose
Glucose is also known as simple sugar and a source of energy and metabolic intermediate. It is made up with monosaccharides (single sugar) such as glucose, frutose and disaccharides ( 2 single sugars connected together) such as sucrcrose, lastose and maltose.
a) The good
It provides us with energy for our body daily activity, thereby reducing symptoms of nervous tension such as fatigue, tiredness and dizziness if it is taken with a equate amount.
b) The bad
i) Insulin
Since it releases sugar like a flash, it triggers the pancreas to release high amount of insulin to counter the high blood sugar in the bloodstream and for energy conversion by driving down the levels of sugar very fast, leading to your brain sending out the hunger again and again. The fluctuation of these process causes over production of certain hormones, resulting in nervous tension and distorting the menstrual cycle.
ii) Blood transportation
The fluctuation of level of sugar in bloodstream over a prolong period of time may cause clotting of the blood and plague accumulated in the arterial wall, limiting the circulatory system in transporting oxygen and nutrients, thus increasing the high blood pressure as our heart having to work harder to make this process possible, causing heart diseases and stroke and reducing the chance of fertility.
iii) Immune system
Glucose has similar structure of vitamin C. Since vitamin C is vital for white blood cells to phagocytize viruses and bacteria, this similar structure decreases the function of immune as high level of glucose, by competing with vitamin C upon entering the white blood cells, leading to less level of vitamin C for making our immune system stronger, causing cells oxidation and lessening the immune fighting ability in destroying foreign invasion.
iv) Liver
Besides secreting bile, liver also stores and manufactures glucose depending upon the body’s need. Researchers found that high amount of sugar intake may not only damage the liver through over-feeding, but may be toxic to it.
v) Allergic reaction
As the liver is damaged caused by constantly high level of sugar in the bloodstream, it is no loner function as it should such as converting foreign substance to the levels acceptable to our body immune system, leading to the immune allergic reaction in attacking the body tissues, including sperm.
vi) Kidney
Simple sugar is considered as yang pathogen, over intake of this type of products for a prolong period may cause kidney yin deficiency, distorting the regular menstrual cycle as resulting of abnormal production of certain hormones such as estrogen and progesterone.

2. Galactose
Galactose ( part of milk sugar) is a type of sugar which is less sweet than glucose with chemical structure C6H12O6. It is found to be coexists with lactose.
a) The Good
i) Immunity
Galactose is vital for the formation of the sugar-based fats and proteins including glycolipids and glycoproteins. While glycoproteins helps the immune system in regulating the formation of cells growth, thus reducing in the risk of cells oxidation, glycolipids strengthens the immune system in fighting against foreign invasion such as bacteria and virus, thus protecting our body against infection and inflammation.
ii) Nervous system
Glactose helps to improve the function nervous system in transmitting information between themselves and regulating the function of certain glands in production of certain hormones, leading to normal menstrual cycle by strengthening the glycoform on the surface of cell membrane, thus increasing the chance of fertility.
iii) Other benefits
Researchers found that The chemical compound glyco nutrients in galactose also improve the digestive system in absorbing vital vitamins and minerals.

b) The bad
Lactose intolerance
Believe it or not Not many people in the world can digest lactose, because of lack of enzyme lactase and our body can not produce it, leading to bloating, gas, and diarrhea.
Although galactose is simple sugar, it is also considered as "low" in the GI index and it is one of the "recommended food" for fertility. we will discuss this subject in an other article.

3. Fructose (fruit sugar)
Fructose is also known as fruit sugar with a chemical structure of C6H12O6, it slowly release blood sugar into bloodstream and has GI index number of 20. Fruits contains frutose include honey, tree fruits, berries, melons, and some root vegetables.
1. The good
It provides us with energy to perform daily activity, thereby deceasing the risk of fatigue, tiredness, dizziness, if not overdose.

2. The bad
a) Triglycerides
Overdose may cause frutose to be converted by liver into triglycerides, thus increasing the risk of heart diseases and stroke.
b) Fructose may interfere with signalling of production of appetite hormones, leading to obesity and food craving and weight gain.
c) Overdose with fructose may cause symptoms of insulin fluctuation as mentioned in glucose.


B. Complex sugar
It is made up with polysacchirades ( many simple sugars connected together) such as starches and modified starches, and non starch polysaccharides (fiber).
The difference between complex sugar and simple sugar is the long chain of sugar and how it effect the sugar levels in the bloodstream after intake. Remember, all of them provide us with energy through liver carbohydrate metabolism. Complex sugar, containing high amount of fiber releases sugar slowly into blood stream and have lower number in GI index.
1. Starches
Starch is produced by all green plants as an energy store and is a major food source for humans. Depending types of starches
a) The goods
i) Either slowly-digested starch or resistant starch.
b) Unprocessed foods such as whole grain
b) The bad
i) Most baked goods or anything made with flour.
ii)) All processed foods

2. Modified starches
A modified starches are chemically modified starches for industrial uses by stripping the outer part and germ of the starches, leading to lose of vitamins and minerals and release sugar just like glucose in the blood stream. It is adviced to avoid this types of food completely if you can or replace them with whole grain or other slowly-digested starches.

3. Polysaccharides
Any of a class of carbohydrates, consisting of a number of monosaccharides joined by glycosidic bonds. It is one
a) Anticoagulants
By reducing the stickiness of platelets, and making it harder for them to build up in artery walls, can also act as anticoagulants.
b) Cholesterol They work both to reduce blood lipid and LDL levels, and raise HDL levels
c) Anti-thrombotic effects.
d) Immune system
Activating T and B lymphocytes, help to regulate immune function, promoting both production of Interferon, a white cell medium, and tumor necrosis (death).
e) Insulin
they benefit diabetics by lowering blood sugar levels; and they improve pancreatic Beta cell function

III. What is GI index or glycemic load
The GI index or glycemic load is a table offered information about how foods effects blood sugar and insulin compare to glucose with GI number of 100
Any foods with number GI number below 55 or glycemic load number under 10 is considered low. Its table contains 1600 foods. Most of our daily intake foods are included in the index.

IV. How complex low GI number carbohydrate affects fertility
In take of carbohydrates with GI number below 55 or glycemic load number under 10 and their derivatives play major roles in the working process of the energy and enhance fertility for women and men alike.

1. Insulin resistance and sensitive
Since it release sugar gradually into blood stream, it does not cause abnormal function of pancreas in secreting insulin to counter the flash of sugar such as glucose, thereby, reducing the risk of insulin resistance and abnormal function of nervous system in hormones production.

2. Does not interfere immune function
Since many complex low GI number contain high amount of antioxidant, they help to increase the immune system in fighting against the abnormal function of immune system in producing certain class of protein binding to sperm and allowing other white blood cells to kill them, thus increasing the chance of fertility.

3. Detoxification
Vegetables and fruits with low GI number contain high amount of fiber, they help to push the large intestine clean, thereby the increasing the digestive function in absorbing vital vitamins and minerals.

4. Nervous and reproductive system
Since most complex low GI number carbohydrate contain high amount of minerals which are important for blood circulation and brain cells in information transmitting , including the nervous and reproductive systems. leading to improve functions of glands in production of certain hormones in regulating the normal menstrual cycle, resulting in decreasing the risk of infertility.

5. Other benefits
a) Cell regulating
b) Weigh loss
c) Muscle strengthening
d) blood clotting
Etc.

V. Carbohydrate for fertility
1. Shifting to slow carbs
a) Whole grain
b) Avoid refine starch
2 Eating low GI index fruits and vegetables
3. Replace daily intake of high GI with low GI foods

V. Summary
Now we known that simple sugar such as glucose is no good to our body, as it will increases the insulin resistance, weakened immune system as well as increasing the risk of abnormal hormones production, leading to infertility. In the other hand, choosing the complexed low GI sugar increase the function in production of certain friendly hormones in enhancing the process of natural conception. Can intake of carbohydrate be the causes of the unexplained causes of infertility ? It is up to you to judge.
