Coronary Artery Disease
Published in Stephen T. Sinatra, Mark C. Houston, Nutritional and Integrative Strategies in Cardiovascular Medicine, 2022
One final disturbing reason is the processing of canola oil. Canola and other vegetable oils are extracted from seeds by crushing them and heating them along with chemical solvents, such as hexane. Hexane is derived from petroleum and crude oil; it is used as a cleaning agent in furniture industries, and as an additive in glue and varnishes. The EPA classifies hexane as an air pollutant, and the CDC says it is a neurotoxin. Although vegetable oil manufacturers may suggest that hexane is completely safe, honestly, I am a little skeptical. I prefer an oil that is not heated at high temperatures or goes through a procedure of deodorization. When it comes to oils, I like cold-pressed EVOOs, as no chemical solvents are used and there is minimal processing. So, the question is – what do you cook with? Firstly, I am not a big fan of high-heat frying with any oil as high heat can cause the oil to oxidize, which tends to enhance inflammatory status. If I do use olive oil or organic butter, I prefer a quick sauté in a minimal heat. If higher heats are required, I prefer coconut oil. If you do not like the taste of coconut oil, avocado oil could be another option. Although I tend to keep olive oil away from the frying pan, I use it for “finishing” meals. It is outstanding when it is sprinkled over thinly sliced grass-fed beef, sautéed veggies like broccoli and asparagus, and certainly salads.
Malnutrition

In addition to increasing the concentration of the infant’s human milk or formula, older infants who consume pureed or table foods can consume increased energy with the addition of nutrients to foods consumed. In general, foods before the age of one are thought to be supplementary energy and protein intake while the child learns to consume various flavors and textures. Many infant foods such as pureed fruits and vegetables are low in energy at baseline. To increase the energy density of pureed foods, one teaspoon of any oil that is liquid at room temperature can be mixed into 4 oz (~120 g) of pureed food. For example, 4 oz (~120 g) of pureed green beans provides approximately 40 kilocalories. With the addition of one teaspoon of canola oil, which contains 40 kcal, the energy density can be doubled to 80 kcal/4 oz (~120 g).
All is changed – changed utterly

Other genetic modifications seek to enhance quality. A genetic trick which prevents the production of the enzyme responsible for the softening process associated with ripening fruit and vegetables means that farm produce has a longer shelf life and so less waste. Seed storage proteins have been engineered to contain much higher levels of the essential sulphur-containing amino-acids. These two amino-acids are deficient in many forms of plant protein, leading to nutritional disease in poorer populations largely dependent on them and unable to afford meat or fish (Figure 11.2). Oil seed rape (canola) is currently being genetically manipulated to produce new ranges of useful and essential oils. Other projects are directed to producing food products containing higher levels of naturally occurring vitamins and other health-promoting molecules.
Plant-made vaccines against parasites: bioinspired perspectives to fight against Chagas disease

Despite no signs of adverse effects have been observed by consumption of foods derived from transgenic plants, some sectors have still shown rejection for more than 20 years although biotech plant cultivation has increased, reaching around 2 billion ha [80]. Even in Latin America, biotech crops of soybeans, corn, canola, among others are currently planted. Thus, the use of edible plants producing recombinant vaccines could be close. However, the biopharmaceutical field has a big challenge on negative perceptions by some people. For instance, people are rejecting injectable vaccines against Covid-19, such as mRNA and DNA even though the scientific community has demonstrated risks and benefits accurately. Thus, the acceptance factor is key to reach marketed vaccines, especially for those derived from transgenic plants.

Among the tested natural oils, the canola oil was hydrolysed to a higher degree by SCNL at a high specific activity (220.00 U/mg). The canola oil contains less than 2% erucic acid and less than 30 mM glucosinolates, and has a relatively low level of saturated fat (≤7%) and a high content of polyunsaturated fats, such as linoleic acid and α-linolenic acid (formally called 9,12,15-all-cis-octadecatrienoic acid). α-linolenic acid is an unsaturated omega-3 fatty acid available in many plant oils. The activity of SCNL was strong for natural oils with medium-chain to long-chain fatty acids [C6:0–C16:0]. Among them, both olive oil (184.80 U/mg) and rice bran oil (176.69 U/mg) contain long unsaturated fatty acids, such as oleic acid and linoleic acid. These results were in accordance with a previous report14, indicating its preference to medium-chain fatty acids and long unsaturated fatty acids.
Experimental validation of acoustic and thermal modeling in heterogeneous phantoms using the hybrid angular spectrum method

Acoustic and thermal property characterization was performed on each gelatin and canola-oil component of the phantoms using techniques that have been previously described [25]. In particular, through-transmission testing was employed to measure the speed of sound and attenuation of the materials using the W-Type phantoms [28]. The density was calculated by dividing phantom mass by calculated cylinder volume. After through-transmission testing with the W-Type phantoms, a commercially available device (KD2 Pro Thermal Properties Analyzer, Decagon Devices, Pullman, WA) pierced the ends of the phantoms for transient-line-source measurements of thermal diffusivity. This device has two 30-mm-long probes spaced 6 mm apart, with one probe being used for heating and the other for temperature measurements. Thermal measurements were not possible in the canola oil with this tool and therefore previously published values were used [29]. The measurement uncertainty of each technique was determined based on the variability of the experimental data or the manufacturer's reported precision.
