When the truth is addressed, we really do not know much about nutrition science, especially its physiological influences on our health. This dilemma results in the ongoing debates about just what is a healthy diet. In reality, nutrition is an infant science that has been ignored by some who feel it is relatively an unimportant factor on our health issues.
Doctors do not help the situation – most will admit that they never received much education about how the diet can affect heath parameters. My own doctor never mentioned the fact that even though I had lost 20 pounds intentionally since my last visit, he never asked me any particulars about the diet that got me there. One would think that he might have inquired if the weight loss was not intentional, therefore indicating a health problem. He also never mentioned the resulting lab value changes, primarily total cholesterol, LDL, HDL, triglyceride, blood glucose, blood pressure values that had improved with the dietary changes I had made on my own.
But most people are not aware of how diet can affect our heath (the emphasis has been only on weight loss). When doctors don’t mention it, patients do not receive the proper information on diet interventions. For example, if their total cholesterol is too high, they are told to eat a low cholesterol, low fat diet (outdated advice) and/or placed on a statin drug. Nutrition science has come a long way since those days from a couple of decades ago. The prudent way would be to give diet a chance. Diet advice is abundant on the internet. However, you should be careful about some of it – look for help from certified nutritionists (Registered dietitians or others with certification from a health coach program, for example.)
The following article written by Reinoud Schuijers explains quite well the problems with the Standard American Diet (SAD) as the three “assassins” – refined vegetable oils, sugar and grains. He seems to follow a keto-type diet; however, research has not yet fully investigated the long-term effects of this highly restrictive plan.
Take charge of your own heath and encourage your doctor to help you take the path to healthy lifestyles. The internet is teeming with diet advice, but use it wisely. In my opinion (contrary to the following article) it may help to consult with a certified dietitian or certified health coach). But you don’t need to follow complicated meal plans – the best diet is one you form based on your lifestyle and food preferences. Say away from highly restrictive plans, fads and detoxification schemes as well as diet pills.
Ever since the advent of plant-based diets, one of the first questions that may come to mind is “how do I get enough protein in my diet?” The following post discusses some protein basics and provides an interesting article on some sources you may not have thought of.
Nearly all people in the United States get enough protein in a balanced macro-nutrient diet each day. The average intake of protein by adults is 98 grams/day, about twice the recommended dietary allowance (RDA) which is for men (56 grams) and for women (46 grams).
The ability of proteins to support tissue construction in the body varies depending on their content of essential amino acids (must be provided by the diet, we cannot make them). Proteins of high quality contain all nine of the essential amino acids and are called complete proteins and include all animal proteins (meat, milk, eggs, and milk products (dairy) and soy (for adults). Incomplete proteins are deficient in one or more amino acids and include plant sources such as seeds, beans, nuts, grains. Fruits do not contain any significant amounts of protein.
You can obtain all the essential amino acids by practicing protein complementation which is the process of combining proteins from different sources so that collectively they provide the proportions of amino acids required to meet the body’s needs. For example, beans combined with rice become together a complete protein by providing all nine of the amino acids.
According to a study carried out by researchers at the University of Sao Paolo, almost 60% of the calories Americans consume each day comes from ultra-processed food.
All foods are processed to some extent. The main problem in the Standard American Diet (SAD), is the high percentage of ultra-processed foods.
What is an ultra-processed food? It’s foods that contain additives like food coloring, synthetic coloring, artificial sweeteners, preservatives, chemicals that give food texture, as well as taboo additives like partially hydrogenated oils. Ultra-processed foods are also typically high in sodium, sugar, and calories. Just read the ingredient list on the food labels (if you have time) and you will soon realize many of these additives are currently in our food supply.
All cells face constant threats from what are known as free radicals. We obtain these potential scoundrels from the metabolism of the food we eat, the air we breathe and from sunlight’s action. Free radicals are in varying chemical states, but their main danger lies in their need for obtaining electrons for stability. In order to do this, they “steal” electrons from nearby substances such as body cells and DNA, causing potential damage and destruction. They may damage the instructions in a DNA strand creating a harmful mutation or create low-density lipoproteins (LDL) that could increase heart disease risk in an artery of the heart, or alter a cell membrane that could affect what enters or leaves a body cell. The body also uses free radicals in a necessary way as part of the immune system to help destroy foreign invaders such as bacteria, viruses, and toxins.
Antioxidants are found naturally in the body such as glutathione, coenzyme Q10, superoxide dismutase among other systems. We obtain many from various foods in the form of vitamins (C, E, beta-carotene and related carotenoids), minerals (selenium, manganese) and various phytonutrients such as flavonoids, phenols, polyphenols, phytoestrogens, and many more found in many plant foods.
Antioxidants probably number in the hundreds or thousands of different substances. Their main function is to act as an electron donor to help squelch the actions of harmful free radicals. Some antioxidants in certain situations can be called prooxidants – electron grabbers. This is likely to be the method found in the defense of the body (e.g. immune system) Nevertheless, they are all considered to be unique with different roles. “So, no single antioxidant can do the work of the whole crowd.” We obviously need a variety of foods to provide as many as we need to get the job done.
Health Benefits of Antioxidants – What’s the Hype?
Antioxidants came into attention when the research suggested that free radical damage may be involved in chronic diseases such as heart disease, cancer, and vision loss. Studies initially indicated that people who ate the most fruits and vegetables had lower risk of these diseases than people who ate lesser amounts. Clinical trials began to test individual nutrients found in fruits and vegetables that were known antioxidants (vitamin C, E, and beta-carotene) to test their efficacy against these diseases. This took the food and supplement industry and media by storm for a long time with proclaiming protection against diseases by consuming large amounts of antioxidants provided by their products.
However, despite these results and disappointments, antioxidant supplements represent a $500 million-dollar industry that continues to grow. Antioxidants continue to be added to cereals, sports and energy bars and drinks, and other processed foods. Lately, however, the hype appears to have abated somewhat due to the reports of no effects of these vitamins and minerals, and phytochemicals (my opinion).
Heart Disease and Antioxidants
In the Women’s Health Study, 39,876 women took 600 IU of natural vitamin E or a placebo every other day for 10 years. The results? At the end, the rates of major cardiovascular events and cancer were no lower among those taking vitamin E than they were among those taking the placebo. One large study (the HOPE Trial) found that those taking Vitamin E versus a placebo showed no benefits vs the placebo and vitamin E and that those in the Vitamin E group actually had higher risks of heart failure and hospitalization for heart failure. Not all trials were negative, however. In a recent trial of vitamin E in Israel, there was a market reduction in coronary heart disease among people with type 2 diabetes.
In the Women’s Antioxidant Cardiovascular Study, vitamin E, vitamin C and/or beta-carotene had much the same effect as a placebo on myocardial infarction, stroke, coronary revascularization, or cardiovascular death, although there was a modest and significant benefit for vitamin E among women with existing cardiovascular disease.
Age-Related Eye Disease and Antioxidants
Some good news for antioxidant supplements was found in a six-year trial, the Age-Related Eye Disease Study (AREDS). The results were that a combination of vitamin C, vitamin E, beta-carotene, and zinc offered some protection against the onset of advanced age-related macular degeneration in people who were high risk for the disease.
Potential Hazards of Antioxidants
Several studies have raised some concerns about supplemental beta-carotene. One study even found that when smokers were fed beta-carotene supplements, the chances of developing lung cancer were increased. Follow-up studies reported the same results. Another possible caution: In the SU.VI.MAX Trial, rates of skin cancer were higher in women assigned to take vitamin C, vitamin E, beta-carotene, selenium, and zinc supplements.
The studies so far have been inconclusive and are far from providing strong evidence that supplementation with antioxidants have much impact on chronic disease prevention. There was some positive benefits of beta-carotene on cognitive function in the Physicians’ Health Study after 18 years of follow-up; however most studies are of shorter duration, so few comparisons can be made.
What to do? There is abundant evidence that the first observations of fruit, vegetable and whole grain consumption were correct since subsequent studies have supported the fact that consumption of antioxidants via eating natural whole foods provides protection against many of our common chronic diseases.
Bottom Line: Get your antioxidants from whole, natural foods, not supplements. Research is still limited and results are not conclusive, but supplement companies still claim benefits even though more evidence of safety and efficacy is sorely needed.
The following article by Shannon Hilson writing on Medium is one of the best weight loss experiences ever This article is written by a real person in a real life situation, not by some so-called diet expert. Some experts tend to espouse nutrition platitudes, leaving the reader feeling guilty, depressed and tired of hearing the same thing over and over again. (my opinion).
This article can pertain to not only dieting (aka as torture), but weight management (staying at your desired weight goal).
The bottom line: Dieting is just not a pleasant state of mind or body – no matter how easy a Nutrisystem commercial may seem – “just eat the food….”
More lessons are to be learned from the French culture. They just keep giving and we (the U.S) just keep ignoring their clues reflected by their lower disease rates (some of the lowest on the globe).
For example, the cardiovascular disease rate: 86.89 deaths in U.S per 100,000 population; 43.25 in France. The obesity rates are much higher in the U.S. than in France. However the lower rates are climbing in France due to less adherence to their traditional diets and their higher intake of Westernized fast and processed foods.
The dietary lessons are relatively simple suggestions(in my opinion). The French generally do not diet or snack. They enjoy food and eat sensibly when it comes to portions. There may be others that are more complex. Please check out the table and graph in the article.
Was a new diet part of your 2020 resolutions? Great, but forget the new fads, diet pills, and starvation deprivation. There are many of the old diets still around- keto, paleo, Whole 30, NutriSystem, Jenny Craig to mention a few. Just look at the magazine covers at the supermarket checkout – keto seems to have taken over all the others. The keto diet is quite restrictive, difficult to maintain and the long-term effects are not known. There is little evidence that this type of restriction, although shown to be effective for weight loss, may not be a lifestyle choice for most people. Is there a better way? In my opinion, yes. The best diet is one you can live with and with a few adjustments compatible with the foods you choose. The best diet is one that with a little guidance and knowledge, is decided by you.
The following article is worth looking at if you want a simple approach. All you need is a plate, a bottle of water, real food and of course, your commitment. And even better, this plan lets you be in control in following a reasonable and evidence-based plan that can fit easily into your lifestyle.
The article speaks for itself and provides a few links to add to the basics, i.e. some things you need to know like a guide to non-starchy vegetables. Oh, you may have to give up fast food and processed foods for a while. But, you may be glad when you realize that you will feel a lot better (and healthier) and the effort will be well worth it.
Don’t get me wrong – I don’t want to say that weight loss itself is easy – it ‘s hard work but worth it when your goals are either weight loss or just changing to a healthier lifestyle. That is why this plan is appealing. it is straightforward and makes sense.
So join the new “non-diet” approach that will help you lose some pounds but even better, eating for health. That is what eating should be about, not body image, eating disorders and food restriction. Learning how to eat rather than just what to eat is the answer (my opinion). ENJOY!!
One more thing – Always consult a registered dietitian, certified nutritionist, and your primary physician to discuss any dietary change to make sure it is nutrient dense. Also make sure you have no underlying medical problems like high cholesterol, hypertension, pre-diabetes, diabetes or digestive issues, for example.
