Mental health and physical health work together. After all, your brain is in your head and your head is attached to your body. Depressed people seem to have more illness than happy people but happy people can get sick, too. Working on optimal health is worth the time spent and can keep you and your children able to enjoy life more, when you're all well.
A quick overview about nutrition and the benefits can be found here. This is the Linus Pauling Institute at Oregon State University and is a wonderful site for free information about nutrition. You can download for free information about nutrients, what foods they are found in, and the problems caused by deficiencies.
A free source of information is here at mentalhealth.gov You can discover quite a bit, just by perusing the site. There are sections on suicide prevention, veterans, and a consumer guide. You also can read about various disorders, if that interests you.
What would you say if I told you that it is not entirely your fault to be overweight?
I, personally, have been studying nutrition since 1979. Still, I don't have all the answers. There is an area which is ignored or not known by most people. It does have to do with nutrition. I sat in a seminar done by a biochemist almost 35 years ago in which he stated that for a person to get the minimum daily allowance of nutrients from food alone, the person would weigh about 400 pounds. The reason he gave for this is that the soil is depleted of nutrients.
Below is a link to a US government study, which seems to support soil depletion, as a fact. It is logical to assume that if the soil is depleted of nutrients for the plants that the plants will be depleted of nutrients that would have been there had the soil been more nutritious for the plants. Therefore, if this is true, it is not your fault. If you want to read more about this here is that link: https://naldc.nal.usda.gov/download/47105/PDF
There are more diets and fad diets around now than there ever have been in the past. It is difficult to know what to do. There is a prominent doctor on the Internet who has done an enormous amount of research about all things medical including nutrition. If you have the time and the interest, you can go to his site and even subscribe to his newsletter to learn more about nutrition. https://mercola.com
Dr. Mercola says that there are types of eating, specific to body types and that everything or one thing doesn’t work for everyone. You can ask your doctor about your diet, but know that either nothing or very little is taught about nutrition in most medical schools, according to eight doctors with whom I have consulted on the subject. If you have any physical disorder, including thyroid issues, you may have a more difficult time with weight reduction, so it is good to be checked out by your own doctor, to determine if this is the case. - Charles Stewart, avid reader, freelance writer
