Grapefruit Nutrition Facts

Grapefruit is widely cultivated in the tropical and
subtropical countries. It is a cross-breeding between oranges and pomelos.

Grapefruit is a citrus fruit that is packed with nutrients
essential for good health and overall well-being. The amazing nutrient profile of
grapefruit has increased its popularity tremendously among the health-conscious
people.

Let's Have a Look at
Why You Should Make Grapefruit an Essential Part of Your Diet:

To begin with, grapefruit has a high-water content, which
makes it low in calories. 100 grams of this juicy fruit contains approximately 40 calories. Hence, weight-watchers can add
grapefruit to their calorie-restricted diet.

Low Glycemic Food

Grapefruit has a low-fat content and a medium carbohydrate
content. The glycemic index of this fruit is 25 and it falls under the category
of low glycemic index fruits. So, individuals with diabetes mellitus who love
this fruit will be pleased to know that it does not cause a sudden spike in the blood glucose levels.

Rich in Vitamin C

This fruit is also appreciated for its high vitamin C
content. The high vitamin C content in grapefruit is valuable to the immune
system. Vitamin C is a natural antioxidant and it has the ability to ward off
something as simple as cold and flu and as serious as cancer. Other beneficial
vitamins present in grapefruit are the members of the B-complex family, which
include:

• Thiamine
• Riboflavin
• Niacin
• Vitamin B6

The list doesn't end here! Grapefruit also contains vitamin
A and E, two fat-soluble vitamins that
are crucial for the functioning of the body.

Minerals in Grapefruit

Grapefruit also contains an array of minerals that are
beneficial for the human body. Minerals present in grapefruit include:

• Calcium
• Magnesium
• Potassium
• Iron
• Zinc
• Phosphorus
• Manganese
• Copper
• Cobalt

Phytochemicals in Grapefruit

Like many other citrus fruits, grapefruit is a great source
of disease-fighting compounds that boost overall health and keep diseases and
infections are bay. Naringen, naringenin, narirutin and hesperidin are the plant compounds present in grapefruit that possess
strong antioxidant and anti-inflammatory activities.

The mildly acidic and slightly bitter taste of grapefruit
juice is due to the presence of naringin
in it.

Grapefruit juice contains highly toxic alkaloids and
saponins, but its strong antioxidant potential is enormous. Hence, the positive
effects of grapefruit outweigh the negative effects.

Research and Scientific
Studies: What Do They Have to Say?

One interesting study found that consumption of grapefruit
is associated with higher nutrient intakes. The study further reported that
grapefruit and 100% grapefruit juice are
a concentrated source of vitamin C and other vital nutrients.

Furthermore, pink and white grapefruit juice was found to have more favorable nutrient
density scores than other commonly consumed 100% fruit juices, including apple,
grape, pineapple and prune.

Similarly, fresh pink and white grapefruit tended to have
higher nutrient density scores when compared to some commonly consumed fresh
fruits such as apples, bananas and
peaches.

The study concluded that consumption of grapefruit was
associated with improved adequacy of intake of key nutrients including vitamin
C and magnesium, and a greater proportion of adults meeting their recommended
intake of dietary fiber.

Addition of grapefruit to your diet can improve the overall
quality of diet for many individuals who are striving to consume a healthful
diet with increased levels of fruits.

Healthiest Fats for Cooking

what should you use to cook with? Healthy alternatives include:

• Coconut oil — This is what I believe is the best cooking oil. It has a number of valuable health benefits, including a positive effect on your heart and antimicrobial properties. It’s also a great source of energy, thanks to its medium-chain fatty acids (MCFAs). When consumed, the MCFAs are digested and converted by your liver into energy that you can immediately use. Coconut oil also helps stimulate your metabolism to encourage a healthy weight profile.

• Olive oil — This oil contains healthy fatty acids that can help lower your risk of heart disease. While the standard recommendation has been to avoid using olive oil for cooking and to only use it cold, recent research¹⁰ in which 10 popular cooking oils were compared, contradicts this advice, showing extra-virgin olive oil actually scored best for both oxidative stability and lack of harmful compounds produced when heated.

• Grass fed butter — Raw, organic butter made from healthy grass fed cows’ milk contains many valuable nutrients, including vitamins A, D, E and K2. Furthermore, it contains various minerals and antioxidants that support good health.

• Organic ghee, which has been used for cooking for thousands of years, is another good choice.

A word of caution is warranted, however. Fake olive oil abounds, so it’s important to take the time to investigate your sources. Tests reveal anywhere from 60 to 90 percent of the olive oils sold in American grocery stores and restaurants are adulterated with cheap vegetable oils or nonhuman-grade olive oils, which are harmful to health in a number of ways.

Peanut oil and sesame oil are two other healthy options. While both are high in omega-6, peanut oil is high in antioxidants, and sesame oil has been shown to benefit diabetics. The caveat with these two oils is that you need to consume them unheated and in moderation, so as not to throw off your omega-6 to omega-3 ratio.

Black Seed Oil — The Forgotten Gem

Black seed (Nigella Sativa) oil is another exceptional fat with a long history of use in traditional systems of medicine, including Ayurveda and Siddha. The most abundant active plant chemical in black seed is thymoquinone; other bioactive compounds include ?-hederin, alkaloids, flavonoids, antioxidants and fatty acids.

As for its antioxidant activity, black cumin seed has been found to be far more potent than vitamin C.

How to Use Black Seed Oil

Black seed oil is a highly undervalued and oft-forgotten kitchen staple. When used in cooking, it imparts a warm, slightly bitter flavor that tastes something like a blend of thyme, oregano and nutmeg.

A mixture of black seed oil, honey and garlic also makes for a powerful tonic that can help soothe coughs and boost immunity, especially during cold and flu season or if you feel like you’re coming down with an infection.²⁸

Like all seeds, black seed oil is high in polyunsaturated fats. So, when taken in excess, it could make your mitochondrial membranes more susceptible to oxidation.

For this reason, I suggest limiting your daily intake to 1 to 2 tablespoons or less. A simple way to get a small amount of black seed oil into your diet on a regular basis is to use it in your homemade dressing. Here are a few suggestions:

• Mix apple cider vinegar, black seed oil, fresh lemon juice, cilantro and tahini. Experiment with the ratios to enhance the flavor you enjoy the most
• A simple and yummy dressing that goes particularly well with broccoli, asparagus or salad greens includes: 1 tablespoon apple cider vinegar, 1 tablespoon lemon juice, one-half teaspoon minced garlic, a dash of ground black pepper and a few fresh basil leaves, chopped
• Alternatively, you can use apple cider vinegar and/or black seed oil as substitutes for other oils and vinegars in whatever dressing recipe you’re already using. Keep in mind that the black seed oil does have a spicy kick to it, so substituting the full amount may make it too spicy. Start by adding just a small amount, and experiment to find the ratio of vinegar, olive oil and black seed oil you enjoy

How to Balance Your Omega Fat Ratios

Ideally, you want to maintain a ratio somewhere in the range of (4-2)-to-1 of omega-6 and omega-3 fats. This, however, is nearly impossible if you’re regularly eating processed foods or restaurant fare, as these are loaded with omega-6 from industrial vegetable oils like corn oil and canola oil.

While you do need omega-6, it should be in its unprocessed form, not industrial vegetable oils. Good sources are whole, raw plant seeds and tree nuts. In summary, to correct your omega-6 to omega-3 ratio, you typically need to do two things:

1. Significantly decrease intake of damaged omega-6 by avoiding processed foods and foods cooked in vegetable oil at high temperatures. A number of studies have found that people who regularly eat deep-fried foods have a significantly increased risk of stroke and death.

Common sources of harmful omega-6 to avoid include corn oil, canola oil, soy oil, hydrogenated or partially hydrogenated fats, margarine and shortening.

2. Increase your intake of marine-based omega-3 fats. Ideal sources include small fatty fish such as sardines, anchovies and herring, along with wild-caught Alaskan salmon, or a supplement such as krill oil.

Processed Vegetable Oils Do More Harm Than Good

In response to research and public opinion, many restaurants have since turned from partially hydrogenated oils to 100 percent vegetable oil. However, while these oils do not have trans fats, they’re just as bad, if not worse. There are three significant reasons for this:

1. When heated, vegetable oils degrade to extremely toxic oxidation products, including cyclic aldehydes,² which have been linked to neurodegenerative diseases and certain types of cancer. In her book, Teicholz cites research showing that aldehydes cause toxic shock in animals through gastric damage
2. Vegetable oils are a concentrated source of omega-6 linoleic acid, which has led to a severe imbalance between the omega-6 to omega-3 ratio in most people’s diets
3. Many of the vegetable oils produced today — especially corn and soy — are products of genetic engineering (GE) and a significant source of glyphosate exposure, and glyphosate has also been linked to gut damage and other health problems

In addition, processed vegetable oils (polyunsaturated fat) harm health by:

4. Creating high amounts of oxidation products when used in cooking (as they are very susceptible to heat), including aldehydes, which are what cause oxidized low-density lipoprotein (LDL) associated with heart disease. Aldehydes also crosslink tau protein and create neurofibrillary tangles, thereby contributing to the development of neurodegenerative diseases.

5. Damaging the endothelium (the cells lining your blood vessels) and causing an increase in penetration of LDL and very low-density lipoprotein (VLDL) particles into the subendothelium. In other words, these oils get integrated in your cell and mitochondrial membranes, and once these membranes are impaired, it sets the stage for all sorts of health problems.

6. Damaging your mitochondria and DNA by making your cell membranes more permeable, allowing things to enter that shouldn’t.

7. Making the cell membrane less fluid, which impacts hormone transporters in the cell membrane and slows your metabolic rate.

8. Inhibiting cardiolipin, an important component of the inner membrane of your mitochondria that needs to be saturated in DHA in order for it to function properly. Cardiolipin can be likened to a cellular alarm system that triggers apoptosis (cell death) by signaling caspase-3 when something goes wrong with the cell. If the cardiolipin is not saturated with DHA, it cannot signal caspase-3, and hence apoptosis does not occur. As a result, dysfunctional cells are allowed to continue to grow, which can turn into a cancerous cell.

9. Inhibiting the removal of senescent cells, i.e., aged, damaged or crippled cells that have lost the ability to reproduce and produce inflammatory cytokines that rapidly accelerate disease and aging.

10. Stripping your liver of glutathione (which produces antioxidant enzymes), thereby lowering your antioxidant defenses.3

11. Inhibiting delta-6 desaturase (delta-6), an enzyme involved in the conversion of short-chained omega-3s to longer chained omega-3s in your liver.4

12. Exposing you to toxic 4-hydroxynonenal (4HNE), which forms during the processing of most vegetable oils, even if the oil is obtained from organic crops. 4HNE is highly toxic, especially to your gut bacteria, and consumption of 4HNE has been correlated with having an obesogenic balance of gut flora. It also causes DNA damage and instigates free radical cascades that damage your mitochondrial membranes.5

13. Exposing you to glyphosate residues, as most vegetable oils are made with genetically engineered crops. Glyphosate has been shown to disrupt the tight junctions in your gut and increase penetration of foreign invaders, especially heated proteins, which can cause allergies.
